How to raise Ji Pineapple

1. Suitable temperature

Ji Pineapple is a very beautiful plant. It has a good strength within a suitable temperature, so the temperature is best to keep about 20-30 degrees Celsius.

2. sunlight irradiation

Sunshine is a maintenance factor that cannot be lacking. It is usually raised in the sun. When it is maintained indoors, it can be raised on the balcony, or it can be raised beside the window facing south.The light in summer is particularly strong, and the sun should be blocked in time to keep it in a cool place.

3. Suitable for potting soil

Most of them are potted plants at home. Choose Flower pots with moderate size and drainage pores at the bottom.The soil must also be prepared in advance, and it can be mixed with corruption soil, cubes ash, river sand, and garden soil.It is necessary to change the pot for one or two years, and the plants can be divided into plants while changing the basin.

4. Water Fertilizer management

When maintaining the pineapple, it can be watered regularly. When watering, pour it from the edge of the Flower pot.The requirements of Ji Pineapple have high requirements for Fertilizer and water. During the growth period, we must apply fat and diligence.

5. Keep humidity

Ji Pineapple has high requirements for air humidity in the growth environment. It needs to be maintained by more than 65%. In addition to ensuring normal roots watering, water spraying water to improve humidity.

6. precautions

Pests and pests need to be controlled in a timely manner, usually like medium -sized diseases and gray mold.Special pesticides can be sprayed. After diluted, it is better to avoid burn plants. It can be applied every half a month and can be applied every half a month, about 3 times.

What should I do if the pineapple leaves are discolored

1. The original leaves of Ji Pineapple were purple -red. It turned green because of the lack of sunlight. Plants could not perform photosynthetic effects, lack of chlorophyll and chlorophyll, so the color gradually changed.If the place where the room is too dark, the markings on the leaves will gradually disappear, the leaf color will become dim, and the value of ornamental will be lost.

2. In addition, too strong direct light will cause the leaves to be burned, and the leaves will appear on the leaves.

3. The pineapple is not cold, so the lower the temperature in winter, the darker the leaf color of the Ji Pineapple.

4. The dry leaves are dry because the air humidity in summer is low, the evaporation is relatively large, and the leaves are prone to water, which causes the leaf tip to dry.

Does Ji Pineapple Blossom

Ji Pineapple blooms.Its flowers are usually gathered, inflorescences, and flower heads are conical, stick -shaped or umbrella -shaped.Because the growth rate of this plant is slow, if it is sowing and breeding, it often needs 3-4 years to bloom.However, it is not only a flowering plant, but also a leaf -seeing plant. The leaves have patterns on the leaves, which look very beautiful.

1. What should I add in the rice nutrition soil

The growth environment of rice seedlings requires ventilation and permeability, so a certain river sand or fine sand can be added.The production method of rice nutrition soil is 0.5 kg of 3 yuan Compound fertilizer per 100 kg soil, or a ternary Compound fertilizer L kilograms with a content of 25%.400 grams of magnesium phosphorus Fertilizer, it is best to spray the water evenly on the nutrient soil, dry and set aside.Before 100 kg of nutrient soil, use 50 grams of enemies, spray it with 8 kg of water and dry it for disinfection.The farm Fertilizer should be rotten and fine -grained Fertilizer.The proportion of soil to the production method of rice nutrition soil to feces is 3: 1. After full mixing, it is Nutritional soil.Before sowing, add 0.5 kg of ammonium sulfate per 500 kg soil, 1.0 kg of calcium phosphate, and 0.5 kg of potassium sulfate.If there is no overlapped calcium phosphate, three -ingredients can be added with di -phosphate.A ammonium sulfate may not be added when adding two ammonium acetate.

Second, the method of preparation of rice Nutritional soil

The production method of rice Nutritional soil should be taken to take fertile surface soil. Do not take life soil and barren soil. Cultivating strong seedlings is the basis of high rice yield, and Nutritional soil is the basis for cultivating strong seedlings. It is recommended that farmers friends should use farm spare time to prepare for preparation of farm time.Good rice seedlings Nutritional soil.As the saying goes, "Tu Fei Miao Wang, Liquor for half a year", it illustrates the importance of fertile soil to rice seedlings.

When taking the dry field soil, you must understand whether the dry field chemical herbicides that have used long residual effects in the last year to avoid drug harm; Nutritional soil is the in -depth development of rice production, and people are prepared in accordance with the growth law of rice seedlings and nutritional characteristics.Special soil can ensure that the seedlings are fully and continuously absorbed from the soil during the growth of seedlings, which has a very important role in cultivating strong seedlings.

When taking the soil in the paddy field, you should disperse the soil, do not concentrate in one place; the requirements for soil are: gardener, soil, and dry field soil are the best, and the surface soil of the paddy field is also available.The production method of rice Nutritional soil generally requires good structure, complete nutrients, high organic matter content, grassless seeds, disease -free pests, and saline -free. For many years, vegetable garden soil, as long as the fertility is high, weeds are less, nutritional nutrition is made, and nutritional nutrition is used for nutrition.When soil, no Fertilizer can be added.The method of stacked with soil, Fertilizer, and grass layers, and high -temperature fermentation methods, that is, according to the number of nutrients required for seedlings, in a relatively flat, high -ground venue, a layer of soil, a layer of fine straw, and a layer of livestock are lively.Poultry feces (can be added with appropriate calcium phosphate) layers of layers, and then watered to wet the soil, cover the soil at the top layer, and then cover the plastic film for high temperature fermentation.After a few days, when the temperature of the pile reaches 100 C, the pile is performed, and then the membrane is fermented, and then it can be sieved.Cultivate a good Nutritional soil, or storage for Bags or storage in place, but prevent rainwater from being washed.The Nutritional soil prepared in this method is due to the high temperature fermentation process, there is no soil transmission, insects, grass damage, safety and hygiene, high Fertilizer, loose soil, good permeability, and a more ideal rice seedling Nutritional soil.

1. How big is the size of the fishing and suede umbrella?

From the perspective of the diameter of the umbrella surface, the main size of 1.8 meters, 2 meters, and 2.2 meters is mainly based on the diameter of the umbrella surface.When choosing a fishing umbrella, the fishing umbrella can buy an umbrella surface for two meters in diameter. Too young will not cover the rain. If it is too large, the trunk will not be put.The shape of the fishing umbrella is a combination of transforming from the beach umbrella and the British Tent. Its materials used are aluminum alloy and fiber. Using fishing umbrellas during fishing can not only block rainwater, but also block the sun.

2. How to install the fishing umbrella

1. First of all, insert the iron fork at the bottom of the fishing sun umbrella into the soil. The edge of the fishing pond is generally the soil structure that can be easily inserted.

2. Then connect the support rod (generally equipped with a rotatable screw) to the iron fork.

3. Open the fishing Solar umbrella and insert the upper bayonet of the hardcore. Some bayonet design has a direction adjustment, which can adjust the direction, and some can not adjust the direction.

4. After inserting, the lock port is completed and the installation is complete.

Third, precautions for fishing umbrellas

1. The fishing Parasol you buy back must be installed and unloaded for the sunshade when used. Be careful, pay attention to putting it lightly, do not throw it at will.

2. When using a Parasol, check whether the screws of the intersection are tightened, and check whether the bracket is bent or deformed.If such a situation occurs, the Parasol should be taken to repair.

3. Pay attention to windproofing for Outdoor fishing. Otherwise, the Parasol is likely to be overturned, especially when the guardian leaves, pay attention to drop the Parasol's foot to the first section.

4. The new umbrella should not be put on hold for a long time, so as not to store long for a long time.Do not fold it with water after the umbrella is used. You should hold the umbrella. Use a soft cloth to wipe the inner and outer umbrella rods and umbrella surfaces, hang it upside down to dry it in the ventilated place, and then close the umbrella and collect it.In order to prepare for the next time, the life of the umbrella can be prolonged, it will not rust and corrodes, and it is also convenient for future use.

5. In addition, the Solar umbrella should be wiped and dried after the room temperature, and then put it away. If you ca nt get hot, you can put it away.

4. How to buy fishing umbrella

1. When choosing a fishing umbrella, you can touch the fabric of the umbrella surface. The fabric of the fishing umbrella surface is thicker than the ordinary umbrella.You can also pull the fabrics with both hands. See if the position of its stitching is strong and firm, and look at whether the surface of the fabric is delicate, uniform, and shiny. Because the fishing umbrella is often exposed to the sun, the fabric must be strong.

2. When choosing a fishing umbrella, you should also test the toughness of the umbrella Bone.experience with both hands, tough tough testing of fishing umbrella bones, twist the umbrella Bone into a bow shape to see if it can be restored. If it can be restored, it means that its umbrella Bone is better, then the wind resistance ability is better.Essence

Sweet potato planting

planting technology

1. Soil

It is advisable to be deep, loose, well -drained, organic with more organic matter, and a certain Fertilizer.This kind of soil is loose, with good breathability, short -shaped shapes, neat, bright Skin, good food, high out of rate, and good storage resistance.

2. color

Seecn beds should be selected from the sun, high terrain, good drainage, convenient management, and fertile soil. It is best to be new seedlings. Old seedlings are often infected with dark spots and nematode diseases.Flink the seedlings of the seedlings once before planting potato, so that the soil grains are fine, the soil is loose, the farming layer is deep, and the chart is raised and raised.The seedlings are determined, generally no more than 6 meters.

3. Select planting

Select healthy potato species with this variety characteristics, distinctive Skin color, strong living power, moderate size (0.15-0.25 kg/piece), strictly eliminate the dark Skin color, cold damage, softened potato pieces, too much water loss, too much water loss, too much water loss, excessive water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water lossMore, and tetanus potato pieces with 70%methyltotobadin 300 times liquid before sowing for 10 minutes to disinfect, the effect is better.

4, density

Plant density varies from season, variety, use, etc.spring and summer potatoes are 3,000-5000 plants per mu, and autumn and winter potatoes are 4,000-6000 per acre.Strive for the leaf area index in the heyday of stems and leaves reached 3-4.5.Due to the continuous cutting of stems and leaves, the feed sweet potatoes can be encrypted to 6000-8000 plants per mu under the condition of multiple Fertilizers.

5. Temperature

The higher the temperature in the range of 16-35 C, the faster and more sprouts.16 C is the minimum temperature of the potato blocks, and the most suitable temperature range is 29-32 C.When the potato block is above 35 C for a long time, due to the great breathing intensity of the potato blocks, the consumption of nutrients, it is prone to "bran heart".When the temperature reaches above 40 C, it is prone to damage to hot and rotten potato.

Diseases and insect prevention

The main diseases of Sweet potato are Sweet potato black spots, Sweet potato stem neck disease, Sweet potato soft rot, potato plague, Sweet potato sore disease, Sweet potato vine disease, Sweet potato root wirling disease, Sweet potato rot, Sweet potato virus disease, Sweet potato purple patternYu Diseases and so on.The main pests of sweet potatoes include nasal insects, crickets, golden Turtles, ground tigers, and Sweet potato moth oblique night moths.The prevention and control of Sweet potato diseases and insect pests should adhere to the principles of preventing and comprehensive prevention.

Mainly controlling diseases and insect pests:

1. Choose a variety of disease resistance, pay attention to the disease quarantine of potato and seedlings.

2. Cultivate disease -free and strong seedlings, choose disease -free potatoes and seedlings from no library areas, or use decontamination seedlings.

3. Use a 50%bacterial or 50%methyltotobadin 500 times liquid to soak the Sweet potato vine for more than 2 minutes, and plant it after cooling.

4. Datian found that the diseased strain should be removed immediately and burned, and sprayed with a 50%fungus spirit 1000 times liquid. According to the situation, it can be sprayed once every 7 consecutive days until the root is eliminated.

5. Thoroughly clean up the diseased plants during harvest, pay attention to the rotation of water and drought, strengthen the management of water and Fertilizer, pay attention to drainage and ventilation, and appropriately appropriately appropriately apply plant ash and lime to make the plants grow strong and strengthen the disease resistance.

6. The main pest control of sweet potatoes can be used with pesticides such as the fear of enemy, killing pine, polyester pesticides, etc. According to the correct explanation, it is usually sprayed in the afternoon.

Potato planting

planting technology

1. Select the plot

The plot suitable for cultivating potatoes should be loose, good for soil, good permeability, rich organic matter, flat terrain, close to water, and convenient discharge irrigation.

2. Reasonable rotation

Potatoes should not be continuous, because the continuous work can increase the pests and pests of the soil, which can easily cause serious lack of certain elements in the soil. The natural balance of the soil microorganism is destroyed, the accumulation of harmful substances secreted by the root system will affect the yield and quality of potato.The previous crop can be rice, corn, green onion and garlic, melon, etc.

3. Reasonable fertilization

It is best to use balanced fertilization (formula fertilization).The Fertilizer of potato is fertilized. Tests have proved that when the tuber produced per mu is 1,000 kg, it is necessary to absorb 5.6 kg of nitrogen from the soil, 2.2 kg of phosphorus, and 10.2 kg of potassium.Potatoes need the most potassium for Fertilizer three elements, the secondary nitrogen, and less phosphorus.

yam planting

planting technology

1. Put the buds of yam seeds into the soil. The interval between lines and lines is about 1 meter, and about 10,000 pieces per acre of land are planted.

2. The growth process of plants such as yam needs to keep the surrounding environment high temperature and dryness, and do not like frost.About 35 days is enough to see Chang Miao.

3. Because the rhizomes of yam are relatively weak, they need to grow upward after emergence, otherwise it will easily wither.

4. Dorodes once a month for half a month, until about half of the shelf height, and then just remove the weeds.

5. Apply Fertilizer at the appropriate time and inhibit the growth of the ground. During the flowering period, fertilization can also be used to increase yield.

6. Properly increase some irrigation. Although yam is a drought environment, it is necessary to water in moderation in continuous drought weather. In the case of continuous heavy rain, it is necessary to drain it in time.

taro planting

planting technology

1. Temperature

taro requires high-temperature and humid environmental conditions. The bulb of the taro at 13-15 C began to germinate.The moderate growth temperature during the seedling period is 20 to 25 degrees, and the temperature growing temperature is 20 to 30 degrees.

2. Water

Whether it is a taro or a riru, it likes moist natural environment conditions.In particular, the leaf is strong and the period of the galvan stems is large. The amount of water requires a large amount of water.

3. Light

taro is more resistant to weak light, and the intensity of light is not very strict. The formation and expansion of the ball stems require short -day conditions.

4. Soil

taro is a happy crop, and its ball stem is formed in the underground soil layer. Therefore, it should be selected to be rich in loam or clay loam with rich organic matter and deep soil layers.

Cassava planting

planting technology

1. Origin environment

Edible cassava generally needs to be planted in areas with a frost -free period and an average annual temperature of 18 C and above.The origin environment of non -rigorous cultivation of cassava should meet the requirements of DB45/T410.

2. Selection and rectification

It should be selected to plant flat or mild sloped sand soil. For example, the planting site needs to be rotated by 2 years, 3 years, etc. The rotation crops are preferably crops such as peanuts, corn, soybeans and mung beans.The whole land is carried out in about one month before planting. Generally, it is two plows and two rakes. It is advisable to be a cultivated land depth of 30-40cm, making the soil flat and loose.3. Variety selection

The varieties of excellent characteristics such as low hydrocyanic acid content (below 100 mg/kg), high yield, high -yield, disease -resistant pests, and strong anti -inverse characteristics.my country mainly has a variety of cassava varieties such as Cutchota, South China No. 9, South China 6068, No. 12 South China, and GR891.

4. planting

The suitable planting time of cassava in my country is from February to April. It is advisable to choose the main stems of full maturity, 2-4cm of stem and diameter, dense section, stem Skin and buds, and disease-free pests. Stems, cut it into 15-20cm in length.The planting method can adopt four methods: flat, oblique insertion, and direct insertion and peaceful insertion. It is better to adopt a ridge covering membrane to plant or take a ridge dewdo plane.1M 0.8m is better.

Prevention and treatment of pests and insect pests

In my country, there are fewer cassava Diseases and diseases. Pests and insect pest control must adopt the principles of prevention -oriented and comprehensive prevention. agricultural prevention and control must be used to prohibit the use of pesticides and mixed preparations for the use of countries.When there is no large area of diseases and insect pests, the method of artificial removal should be used and destroyed in time;Secondly, measures such as weeding and soil cultivation can be created to create ecological conditions that are not conducive to the occurrence of pests and insect pests, but it is beneficial to or not hinder the growth of cassava growth.If the area of disease and insect pests is large, high -efficiency, low toxic, and low -residue pesticide varieties need to be selected for prevention and treatment.Cotenato grass damage is recommended to use artificial, machinery and cultivation techniques to prevent removal, such as ground film covering weeding technology, plowing Fertilizer and soil technology, and setting.
