The preservation period of common vegetable seeds

1. Tomato seeds.It can generally be stored for 3 to 4 years, and the longest does not exceed 4 years, otherwise the bud rate will be reduced.The simple method of identifying the old and new seeds: new seeds have hairs and tomato flavors; old seeds have fewer Skin and less fur or fall off.

2. Cucumber seeds.It can generally be stored for 2 to 3 years, exceeding this period, and the germination rate generally decreases by 20%to 30%.

3. Eggplant seeds.storage time is generally within 6 years.The exterior Skin of the new seeds is shiny, and the luster decreases differently due to the different storage period.

4. Chili seeds.Can not exceed 3 years.The seed germination rate of 2 years was reduced by about 10%, and the storage of 3 years was reduced by about 30%.The new seeds are golden yellow and the seeds are apricot yellow.

5. Onion seeds.summer planting onions, applying new species.If the aged species is used, the green onions will draw the seeds.spring green onions can be used in the first year.

6. Celery seeds.It can be stored for 3 years, and the seeds cannot be used in that year. It should be used for 1 year.

7, leek seeds.The new species of the year was good, and the germination rate was reduced in 2 years.

8. Cabbage seeds.It can be stored for 2 years and can be planted in that year.For more than 2 years, the seedling rate is reduced by 20%to 30%, and the disease resistance is reduced.

9. Coriander seeds.It should be used after 1 year of storage, and the storage time should not exceed 3 years, otherwise the fragrance will be reduced.

Vegetable seed storage method

1. First of all, the harvested seeds should be screened and picked out the grain, soaked, soaked, and cracked granules. Such seeds are easy to turn back to deteriorate, which will affect other seeds.Full seeds.

2. Try to dry the filtering high -quality seeds. The seeds must be dry and dry, otherwise it will be easy to get back and mildew.Some families without agricultural experience have no judgment experience of the dryness of the seeds. These families may have electronic scale. Therefore, they can take some samples to weigh every day. When the weight of the seeds is not alleviated, it proves that the seeds are dry enough to dry enoughEssenceOf course, the seeds cannot be exposed, otherwise it will affect the germination rate.

3. After the seeds are dried, in order to prevent insects from the seeds, the seeds need to be packed into a sealed container such as jar, sealed Bags.Although the seeds are dried, they are still breathing and their ability to live. Therefore, the container cannot be completely seal and impermeable. Otherwise, the seeds cannot breathe and lose their vitality and die.The container should be placed in a cool and ventilated place.

4. In order to be able to completely prevent insects, you can mix the seeds and insect -proof drugs. Generally, you can use the bosom spirit for ant -driven ants sold in the market.Mix the anticardy -proof medicine before being packed in the container, and mix the medicine evenly.

5. Because the pores are opened for the container, the seeds in the container are still likely to absorb moisture. Therefore, in order to prevent seedlin, you can go to the market to buy some desiccant packets and put it into the container to reach the moisture -proof effect.If you can't buy a desiccant, you can also use breathable paper to use a little lime instead of the desiccant packet.

6. Another trick is a good way to save the seeds in the ancients: on the sunny day, choose a wall that is good, avoid rain and the sun, find some rotten mud, mix the seeds into the mud, and then apply the mud to the wall to the wall., Will be planted in the coming year, and then buckle the mud from the wall.This method not only prevent insects, but also prevent mildew.

1. How much is a pound of konjac seeds?

The price of konjac seeds is about4~6A pound around the yuan, but there are differences in different prices such as the quality, variety, origin and market of seeds.In fact, the "seed" of konjac is not the seeds of botanicals. The formation process is very special. The "seeds" of konjac "seeds" with sexual reproduction are a typical non -sex organs -small spherical, seed first and second generationDifferent prices, the price of different places is different, and the price is large.

2. Where can I sell konjac seeds

There are farmers' markets or seed stores.

Konjac is cold, Xin, toxic; can promote blood circulation and stasis, detoxify and swelling, wide intestines and laxatives, phlegm and softness; Indications to lower blood pressure, blood sugar, phlegm nucleus, damage and bleach, stasis, stomach pain, sore throat pain, gums, gums, gums, gums, gums, gums, gums, gums, gums, gums, gums, gums, gums, gums, gums, gumsSymptoms and other symptoms.In addition, konjac has the effects of calcium supplementation, balanced salt, clean stomach, intestines, detoxification and other effects.

The grape glycosan with the largest content in the konjac has a strong expansion power, and has more than any kind of plant glue.You can fill the gastrointestinal and intestines to eliminate hunger, and because the heat it contains is minimal, it can control weight and achieve the purpose of weight loss and bodybuilding.

Konjac contains a gel -like chemical, which has the magical magic of anti -cancer and cancer.As long as the mature konjac is separated by simply extraction, it is made into a konjac fine powder, and the fine powder is added to the water, and the konjac gel can be produced.After being eaten into the body, this gel can form a translucent film coat, which is attached to the intestinal wall, which hinders various harmful substances, especially the absorption of carcinogens."Anti -Cancer Demon Cloth".

Konjac also contains a natural antibacterialin, which uses konjac fine powder as the main raw material. After making foods with other raw materials, konjac can form antibacterial membranes on the surface of the food, which can prevent bacterial invasion, extend the storage time, and play fresh and anti -bacterial bacteria.effect.

Third, the cultivation of konjac

1Soil: Konjac requires deep soil layers, loose and fertile, and neutral sour sandy loam planting rich in organic matter and humus.pH (pHAlkaliCurefor6.5~7.5GenerallypH5.5~6.5orpH7.5~8Both can grow.

2Humanity: Konjac requires good soil drainage, low groundwater level, and soil water content50~65%The sandy loam, the relative humidity of the air55~70%The annual rainfall is1000~1500Millimeter.

3, Temperature: Mochia fertility requirement for temperature15~25, exceed35growth is suppressed, lower than12The upper part of the ground is naturally poured, and the dormant period can be patient-5, lower than-8The lump of the ground is frozen.

4Light: Konjac is a shade -resistant crop. It is most afraid of light and direct shooting. It requires that the sunshine intensity is weak, the time is short, and the most suitable light intensity developed on the ground is sunlight.1/3The root development requires dark light.

Fourth, how to plant konjac seeds

1Following land fertilization: After the konjac is selected, the land is deeply cultivated once in autumn and winter. When farming, it can be combined with farming home Fertilizer according to the actual situation.1Mi Baogou,15~25centimeter.

2Plant taro selection: Select the seeds of konjac seeds to choose a small and shallow barogy nest, full ball stems, thick top buds, and the upper part of the tuber1The traces of the circle or falling off the roots of the beard, the lower and the bottom surface and the bottom surface, no root, no wrinkles, no scars, no injuries, weight is in300Gramm.

3, Plant taro disinfection: Monaco seeds should be used before sowing1000The agricultural chain -soluble powder of the units of 10,000 units to the water20kilogram(1000ppm)Soaked taro0.5~1Take it out and dry it after hours1~2God, this can reduce the occurrence of diseases.

4planting time: Konjac seeds are generally treated10Cm earthen temperature stable12Sowing only above , according to the climate of various places, it is usually in various places3It is advisable to be from the beginning of the month to late April, and it can be planted before the winter at the latest.

52. Sowing method: When the konjac is planted, the two lines of adjacent rows should be staggered and placed.45In the diagonal gap, the slope is budding upwards, and the taro is the root -shaped stem. The top buds are continuously placed in one direction, and then covered with soil.

Five, the planting management of konjac

1Cover management: After the konjac is broadcast, it should be vigorously collected by various crops, horn, shells, dead leaves and other coverage to meet the standard of "grass can not be made, and the ground is not exposed".2000About a catty,9After the month, pay attention to removing unwroded covers.

2Clear weeds: The root of the konjac roots is shallow. In order to prevent the young and tender root system and underground stems that are developing in the middle of the cultivation, it will affect the normal growth of the plants. You can use manual removal of weeds.On the surface, to prevent pressure from underground root stems.

3Clear ditch to cultivate soil: Konjac is afraid of drought and should not be impregnated. Therefore, the planting fields should be checked in the ground after the rainy season, especially after heavy rain, and drainage water to ensure that the water roads are Smooth.Combined with the Qing ditch, the fine soil inside the ditch is cultivated into the ridge surface.

4Scientific Fertilizer: Monacon topdressing is mainly to apply rotten dung water when leaf exhibition leaves. You can also apply dried pork dung slag to the soil to absorb the roots of the konjac roots between the plants.Following pursuit, Compound fertilizer with insufficient bottom Fertilizer.

Six, the diseased and insect prevention of konjac

1soft rotten

[Symptoms] Affects petioles, ball stems and leaves. After the victim, it tissue black, softened, and emitting a smelly odor, and even the fruits were rotten and inverted.

[Prevention] Strengthen the management of cultivation, regularly cultivate rectification, drainage and ventilation. When choosing seeds, carefully select non -rotten, wound -free taro, and soak the agricultural linolentin solution of appropriate proportion before sowing.

2White silk disease

[Symptoms] Affects the base of the petiole, which will cause damage to the petiole or ball stem.

[Prevention] Strengthen management and timely eliminate stagnant water, do not connect with peanuts, eggplant and soybeans, and use the proportion of Bordeaux liquid to switch to the spray of the petiole and the soil surface when the konjac fluid is switched to the bulb's stem expansion.disinfect.

3Leaf blight

[Symptoms] Harmly leaves, the infection ability of the germs is extremely strong, causing the konjac to wither and die.

[Prevention] The prevention and governance measures of leaf blight are basically the same as soft rot.

4Pest

[Symptoms] The insect pests that affect the growth of konjac are mainly Sweet potato moths, konjac lineworms, and bean moths.

[Prevention and treatment] Remove weeds and dead leaves during winter and spring, use konjac and corn for field sets. It can also use artificial insecticides to remove insect pests, and pay attention to choosing rotten farmhouse Fertilizer when using farmhouse Fertilizer.

When is Wheat mature

The Wheat varieties planted in different areas are different and the sowing period is different, so the maturity period is also different.If it is planted for winter Wheat, it is usually sowing in autumn, and it is mature from late June to early July in the next year.If it is planted spring Wheat, it is generally sown between the Qingming season and May, and it matures in mid -July to late August.The Daxinganling area matured in mid -August to early September.

Generally speaking, the harvest time of Wheat should be determined according to the maturity of the Wheat.The maturity of Wheat can be judged by observing the appearance of Wheat and determining the moisture content of Wheat seeds.When the Wheat grains are yellow, the shell becomes light yellow or white, the grains are hardened and the moisture content is reduced to less than 15%, and it can be considered.

However, it should be noted that the harvest time of Wheat is not fixed, and it is also affected by factors such as weather, soil and planting technology.For example, if the weather is too humid or too dry, it will affect the maturity and output of Wheat.In addition, if Wheat planting density is too large or insufficient fertilization, it will also cause poor Wheat growth, which will affect the maturity and yield of Wheat.

Therefore, when choosing the harvest time of Wheat, we need to consider multiple factors.In addition to observing the appearance of Wheat and determining the moisture content of Wheat seeds, it is also necessary to adjust according to factors such as local weather, soil conditions, and Wheat growth.If the weather is too humid or dry, it may be necessary to delay or harvest time in advance.If the Wheat grows poorly, some remedial measures may be taken, such as increased fertilization or adjustment of planting density.

When is the most suitable sowing of Wheat

1. winter Wheat

It is usually sown in autumn so that Wheat can grow a certain root and leaves before winter, thereby safely and overwinter.In temperate areas, the suitable sowing time of winter Wheat is usually from September to November, and the specific time depends on the local climate and soil conditions.

2. spring Wheat

Sowing in spring, the growth cycle is short, no need to experience winter.spring Wheat sowing time is generally from March to May, especially when the temperature of the soil is stable above 10 C in spring.

Wheat planting method

1. Land preparation

Wheat adaptability to soil is wide, but good soil conditions are the basis for improving production.Before planting, deep cultivation must be performed. The depth is generally not less than 20 cm to break the bottom layer of the plow, improve the soil structure, and improve the water and Fertilizer ability of the soil.At the same time, according to the condition of soil nutrients, the base Fertilizer is reasonably applied. Generally, Organic fertilizer is 2000-3000 kg per mu, and the Compound fertilizer is 50-60 kg to meet the needs of the entire growth period of Wheat.

2. seed treatment

Selecting high -quality, high -yield, and disease -resistant Wheat varieties are the key to increasing production.Corresponding to the seeds before sowing, remove the grains, pimples and impurities to improve the purity of the seeds.At the same time, the seed coating or pharmaceutical species can effectively prevent underground pests and soil -transmitting diseases, and ensure that the seedlings are strong.

3. Sowing technology

Wheat sowing should master the appropriate amount, sowing depth and sowing method.The amount of sowing is determined according to factors such as variety characteristics, soil fertility, and climate conditions. Generally, the amount of sowing per mu is about 10-15 kg.The depth of sowing is appropriate for 3-5 cm, and excessive or too shallow is not conducive to emergence.The sowing method can be rake with mechanical strips or sprinkled to ensure that the seeds are distributed evenly and the soil is strictly covered.

4. Irrigation and drainage

During the growth of Wheat growth, the amount of water is large, especially in the extension period, the pregnancy period and the grouting period. The water should be irrigated in time according to the soil emotion and weather changes.At the same time, pay attention to drainage and waterlogging during the rainy season to prevent the stagnant water in the fields from being damaged by Wheat root system.

5. Fertilization and fertilization

During the growth of Wheat, nitrogen, phosphorus Fertilizer and Potassium fertilizer should be applied in a timely manner according to the conditions of seedlings and soil nutrients.Especially in the extension period and pregnancy period, the appropriate amount of nitrogen fertilizer can significantly increase the yield.In addition, leaf surface Fertilizers such as dihydrogen phosphate can also enhance Wheat resistance and improve quality.

6. Prevention and treatment of diseases and insect pests

During the growth of Wheat, it was easily attacked by a variety of diseases and insect pests, such as rust, giant mold, aphids, and pulp insects.Comprehensive prevention and control measures combined with agricultural prevention, biological control and chemical prevention should be adopted to reduce the amount of pesticide use and ensure green production of Wheat.

7. Weeding and China Farming

Clear weeds in the field in time to reduce nutrient competition and improve ventilation and light transmission conditions.Mid -cultivation can be loose soil, promote root development, and improve soil temperature, which is conducive to Wheat growth.

8. Harvest and storage

After the Wheat matures, it should be harvested in time to prevent losses caused by natural disasters such as rainfall and wind.When harvesting, choose sunny weather and use a joint harvester for mechanical harvest to improve harvesting efficiency.After harvesting, it should be dried in time to reduce the moisture content to prevent mildew.When storage, the warehouse should be kept dry and ventilated, and regular inspections should be kept to ensure the safe storage of Wheat.

[rice species germination] Points of rice seeds soaking germination technology point Points of rice seeds precautions precautions

The main points of rice seed soaking germination technology

rice seeds need to be exposed to planting for 2-3 days before soaking to improve the germination and germination rate of seeds.However, it is not advisable to grow on the cement floor and slate.When soaking, seed disinfection should be performed, and then soaking.rice seeds are soaked in water soaking. If you really need to be soaked in static water, you must be squeezed or changed at least twice a day.Generally, early rice is soaked for more than 48 hours, and medium and late rice must be soaked for more than 36 hours.

After soaking, the buds are mainly grasped, mainly at high temperature (35 C -38 C) breaking the chest, the temperature (25 C -30 C) long buds, low temperature (normal temperature) dry buds to practice buds.The temperature and water of the valley species are adjusted in the method of leaching temperature and covered with closed coverage, and the temperature and humidity are uniform in the inside and outside of the valley piles in the piles, which makes the buds and roots be consistent.The criteria for germination are half a grain of buds and a grain of root.

1,Expose

Select the seeds one week before the routine rice seeds soaking6 to 8 hours, then put the sun -exposed seeds in a dry and cool place to cool the heart to promote the breathing effect and enzyme activity of the seeds, which is conducive to improving the seed germination rate and germination potential;Bacteries attached to the rice shell.However, do not expose the hybrid rice seeds before soaking. After the exposure is seeding, the germination rate is generally reduced by 5%to 10%. The negative impact on the seeds with weak living power is greater.

2,Seeding

Select the seeds with water, remove the floating on the surface, and choose a full rice seeds to cultivate neat and strong seedlings.

3,Promote living water soaking

It is not easy for the planting time, it is best to useThe method of "daily immersion and night dew" is to soak the seeds during the day and remove it at night. It is best to put the seeds in the flowing water for 6 hours when soaking (if there is no flowing water for about 4-6 hours, it will be changed once every 4-6 hours).To eliminate the direct soaking of the old (old) for 48 hours.

Adopting intermittent soaking methods: the best time for conventional early rice soaking33-35 hours, more than 48 hours are not conducive to seed buds and germination rates.(The specific soaking time depends on the temperature and water temperature, and the seeds are used to suck water.seeds have suck water).Miscellaneous early rice should be used to decline, intermittently immersion method, and avoid continuous soaking for a long time.The process of rice soaking in rice is the water absorption process of the seeds. After the seed absorption, the activity of the seed enzymes begins to rise. Under the action of enzyme activity, the embryo starch is gradually dissolved into sugar, releasing the nutrients required for embryo roots, germ and embryo axis.When the rice seeds absorb water to the valley weighing 24%, the embryo begins to spare, saying that it is broken or dew.When the seed absorption reaches 40%, the seeds can germinate normally. At this time, the water absorption is the saturated water absorption of the seeds.When the amount of water absorption is reached, on the one hand, due to the water temperature of the soaking, the higher the temperature within a certain temperature range. The faster the seed absorption, the shorter the water absorption time.On the other hand, it is affected by rice varieties and combination types.Due to the strong activity of hybrid rice water absorption, the soaking time of hybrid rice seeds is shorter than the soaking time of conventional rice seeds.

4,Promote pharmaceutical soaking

It is recommended to use potion soaking, except for coating seeds.Water soakingAfter 6 hours, the bacterial spores attached to the seeds moved, and then the pharmaceutical sterilization was performed.At present, the commonly used potions are 25%fresher 2000-3000 times liquid (that is, 5 kg of 2ml of water, 4-5 kg of planting 4-5 kg) for 6 hours.Or use 500 times strong chlorine essence (2 grams of strong chlorine essence and 1 kg of water) for 6-8 hours, the disinfection solution should be higher than the surface of the seeds (do not change the water during disinfection), and then repeatedly rinse the rice seeds with water repeatedly.Rinse the residue solution.

5.Sprout

At present, many farmers like to put seeds in woven Bags to germinate, and even because the temperature cannot come, the seeds are exposed to the sun, which often causes burning buds.The best and easiest way is to use double -layer, disease -free, and moist sacks to germinate, put a layer of diseaseless straw on the ground, spread a sacks, spread the seeds evenly, and cover the other sack on it.Just pay attention to whether to add water.You can also put a sack or a relatively ventilated woven bag, and you can use straw to keep the insulation.After the valley species is heating, the control temperature is in35-38 C, the temperature should be piled up with too high temperature, and measures should be taken to improve the pile temperature.After about 20 hours, the grain can be exposed.The temperature is normal in mid -to -late May, and the daily immersion and night exposure method can be used to germinate normally without the need to add insulation materials.

6.Refining

Before sowing, spread out the germination of germination at room temperature to refine the budsSowing after 3 to 6 hours.Make valley species adapt to air temperature and improve the seedling rate.

7.Sow

After the grain species is dew, the temperature is adjusted toFrom 25 to 30 C, the temperature can be promoted to the roots. When the buds are half a grain of valley and 1 grain of the roots, the lower fields can be sown.

precautions for rice seed germination

1,Flip it every day when germination1-2 times, the temperature of the seeds is uniform, the temperature of the upper and lower, the temperature is uniform, and the germination is neat.

2,When germination, you must pay attention to temperature changes, prevent and control high temperature burning, exceed40 C seeds lose their germination.

3,seed85%broke the chest, reduced the temperature to 25 C, the buds and root length were controlled within 2 mm, and the plant was spread out.

4,After breaking the chest, proper water replenishment, pay attention to the ventilation and oxygen, you can urge the strong bud.

5.According to their respective production plans, the germination, sowing in a timely manner, and controlling the seedling age in3.5 Leaf age, prevent small seedlings in the early stage, and insert large seedlings in the later stage.

How to grow tomato seeds to grow tomato seeds for a few days to germinate

How to grow tomato seeds

The small tomato seeds that have been dried on the paper will be exposed to the sun for a day before planting (the germs and viruses are eliminated, and the germination rate is increased), and then the seeds that have been dumped into pieces are scattered into pellets.

This is the key step of tomato seeds that cannot be omitted.

Turn the rake flat and the sun, rich in humus, fertile Fertilizer and loose seedlings "beds", and then lay a layer (20 mm thickness) on it.

First spray the water in the seedling bed, then sprinkle the small tomato seeds evenly on the seedbed, and then support the arc -shaped bamboo skeleton to cover the plastic film, and use stones and soil pressure to be surrounded by the surrounding area (moisturizing and insulation)Essence

How many days do tomato seeds germinate?After 3-5 days (temperature factors), the seeds will sprout. When the embryo leaves grow, they should open a plastic film on the morning of the day to change the fresh air for them.

When the true leaves appear, they should carefully spray the light feces urine and Fertilizer with a romance pot.

When the soil in the cultivation bed is dehydrated, it is necessary to supplement it with a barrel in time.

In this way, you can transplant it in the planting field without a month of operation (use a flat shovel to cut one inch of thickly cultivated soil to take the seedlings, and the soil transplants will return early).

Many people growing tomatoes are not very good. They waste a lot of manpower and material resources. At this time, you need to learn more about tomato cultivation technology. Speaking of tomato cultivation technology, Xiaobian is the expert in this area.Let me introduce the tomato cultivation technology.

Tomato cultivation technology

1. For environmental conditions

Temperature: Tomatoes have strong adaptability to temperature and can grow at 10-30 C temperature.There are certain differences in temperature requirements at different fertility stages.The optimal temperature of the seed germination is 25-30 C, the minimum temperature of the germination is 12 C, and the temperature of the seedling period is suitable during the day.

Among the tomato cultivation technology, temperature is the most critical point.

2. Main cultivation technology

1. Cultivation season: Export processing tomatoes are mostly for open field cultivation.Tomato is a vegetable crops that are not resistant to high temperature and are afraid of frosting, and are suitable for planting during a frost -free period at an average temperature of 15 C or more daily.

2. my country's region is vast, and the north -south climate is very different. Lulba planting tomatoes are generally in South China such as Guangdong, Guangxi, Fujian and other places. There are no frost throughout the year.

3. In summer, high temperatures are more rainy, and typhoons often have typhoons. Only autumn and winter weather is fine, sufficient light, less rain, warm climate, most suitable for planting, generally sowing from August to October, transplanting in September to October, starting in mid-November, starting in mid-November.Receive until late February of the following year.In the middle and lower reaches of the Yangtze River, the frost -free period is very long and can carry two stubbles a year.spring stubble generally sowed seedlings from November to December, planted in mid-to-late March of the following year, harvested in mid-to-late May, and seedlings were pulled in mid-to-late July;Harvest in early October, and in late November.
