1. A few shots of Shading nets are best

For the greenhouses that plant vegetables, not only should it be clever in summer, but also shade and cover the shade net.The shade net is divided into two, three stitches, four stitches, six needles and other species according to the fine degree of density or light transmission.The Shading net is too sparse, the Shading rate is not high, and the cooling effect is poor.The Shading net is too dense, the light is too small, and the vegetables are easy to grow.

After a summer practice, the greenhouse Shading net generally uses a three -needle Shading net, and two -needle Shading nets can also be used.Essence

At the same time, when the temperature is high in summer, the cooling effect can be enhanced by covering two layers of sunshade nets. The first layer is fixed, relatively sparse, and can be used with two stitches.The other layer is activity. You can use three stitches to open it when you need it, and put it away when you do not need it.Generally, the temperature of the temperature will be on the event at 10 am to 11 am, and the Shading net on the activity will be opened. When the temperature starts from 3 to 4 pm, it will be put away when the temperature starts to steadily decrease. This can control the temperature to a certain extent.Not long.

Second, the more the number of ungathetic net needles, the better, the better

Seeping a few stitches represent the number of pins in each inch. The more the number of pins represents the dense the eye, the better the Shading effect, but the too large number of needles will also cause the shade net to be too heavy, which is not conducive to ventilation and ventilation.Therefore, the number of needles for the choice of Shading nets needs to be determined according to the actual usage and needs.To achieve a good Shading effect, it will not affect the circulation of indoor air.

The main function of the Shading net is to block the sun and prevent plants from being sunburned or sunburned.If you want plants to better photosynthesis, you can choose a low -number of pins (such as 3 stitches or 4 stitches) may be more suitable.If you want to sunscreen better, you can choose a high -number of pins (such as 6 or 8 stitches).

1. What types of Shading nets

1. Round silk Shading net

Because the Shading net is woven by the meridians and weft lines, it is mainly woven by the editorial machine. Therefore, if the meridians and weft lines are woven by round silk, it is the silk Shading net.

2. Flat silk Shading net

Both the meridian and weft lines are flat -filaments woven.

3. Round flat silk Shading net

The meridian is flat wire, the weft line is round wire, or the meridian is round wire, the weft line is a flat wire.

2. How to choose a Shading net

1. color

The commonly used Shading nets include black, silver -gray, blue, yellow, green and other types. Black and silver -gray are used most commonly in vegetable coverage.The lighting and cooling effect of the black Shading net is better than the silver gray shade net. It is generally used for crops with low temperature and high temperature seasons and low requirements for light and light viral diseases.Capelles and other green leafy vegetables such as coriander and spinach.The silver -gray Shading net has good light transmission and has a aphido effect. It is generally used in the early summer, early autumn and the requirements of high -oriented virus diseases, such as radishes, tomatoes, Pepper and other vegetables.It is used for winter and spring anti -frozen coverage. Black and silver -gray Shading nets are available, but the silver -gray Shading net is better than the black sunshade net.

2, Shading rate

During the weaving, the shade net can regulate the density of the weft, so that the shielding rate can reach 25%to 75%, or even 85%to 90%.You can choose in different needs in the cover cultivation.Xiaqiu covers cultivation, and the requirements for light are not too high. The small cabbage and other green leafy vegetables with high temperature can be selected from the Shading net with a high shielding rate.

For fruit and vegetables with high light requirements and high temperature resistance, you can choose a sunny net with a lower lighting rate.winter -spring anti -frost and anti -cream covers is effective with a sunshade net with a high shielding rate.In general production applications, the Shading rate is generally selected from 65%to 75%of sunshade nets.When using it, it should be adjusted according to different seasons and weather conditions, by changing the time to cover and adopting different cover methods to meet the growth needs of different crops.

3. Width

The range of general products is 0.9 meters to 2.5 meters, and the widest is 4.3 meters. Some manufacturers can also be customized as needed.The use of 1.6 meters and 2.2 meters is currently more common.In the coverage cultivation, multiple stitching is used to form a large area of coverage. It is convenient to unveil the cover during use, easy to manage, save labor, save effort, and facilitate fixation. It is not easy to be scratched by strong winds.It can be stitched according to the length and width of the coverage area.When cutting the Shading net, the cutting iron should be scalded with electric iron.When stitching, the cotton wire cannot be used, and the nylon wire should be sutured to increase the stitching firmness.

Is the fermented fruit Skin the nitrogen fertilizer?

In fact, after the vast majority of fruit Skin is fermented, it can make nitrogen fertilizer.For example, after the banana peel is fermented, it can be made into nitrogen fertilizer. Both orange peel and apple Skin can be made into nitrogen fertilizer.

How to make fruit Skin production methods

1 You can chop the fruit Skin, and then put it in the sealing of the utensils prepared by everyone. It needs to be poured into the water and placed in the place where the sun can illuminate. 15 arrive 60 God, it can ferment very well.But everyone must pay attention, the utensils must be left 20% The upper and lower parts can prevent the gas from rising under the condition of fermentation, and then the utensils explode.

2 Or prepare a potted Flower pot in advance, put some soil layers in the potted Flower pot, and then spread the peel on the soil layer. In the second floor, a layer of peel should be paved.In addition, in this kind of push, that is so thin 5cm Green plants can be planted in the case of up and down.

What flowers are suitable for fermented fruit Skin

1. Apple Skin

1 As well as Apple fermented water is acidic and can be used to pour acid -like flowers. Most southern flowers are acidic, such as Milan, gardenia, azalea, Clivia, Jasmine, Fairy Classes, Cylinder, Smile flowers, Tong Tong, Golden Flower Tea, Costume, Red Palm, etc.Essence

2 As well as Watering apples of these flowers can not only improve the acid and alkali of the soil, provide a more suitable environment for flowers. Rich nutrients can also supplement the flowers with appropriate nutrients, making the leaves thick green, making flowers bloom more, Promote the growth of flower health.

2. Orange peel

1 , Orange Skin water is slightly acidic Fertilizer, suitable for like acidic plants, such as rhododendrons, laughing, Bailan, jasmine, gardenia, osmanthus, bacheme, ivory red and so on.

2 , Orange Skin is rich in vitamins and sperm oil. Under the dissolution of water, the nutrients in it will be acidic in the soil, which can well change the acid and alkali of the soil.If it becomes fade, it will provide the nutrients required for the root system, which is more beneficial to the growth of flowers.

[Plant seed preservation method] What are the commonly used seed storage methods of seed preservation method?

Several seed storage methods commonly used

seeds are the most basic agricultural production materials, the internal cause of agricultural production, and the carrier of various technical measures.Therefore, it is a key link in agricultural production, and it is also an important task in rural winter and spring.If the necessary knowledge and poor management will cause serious harm to pests, resulting in a reduction in the videline of the seeds, a reduction in the number, and severe the seeds of seeds, which will greatly lose agricultural production.Now introduce the storage methods of several main crop seeds:

1. corn

1.Ears store

This is a method of storage that is both economical and effective.This method is conducive to the cooked and dry after the seeds, reducing the harm of warehouses and microorganisms, but the use of warehouse capacity is low.Specific method: In the dry and cold area of winter, use sorghum stalks to prepare corn warehouses in the open -air venue and store fruit ears overwinter.Or leave the autumn corn ears.Suitable for farmhouses to store a small amount.However, this method should not be adopted in areas with high temperature and high humidity, because under such environmental conditions, corn can easily absorb moisturizing and recover, insects, mold, and dry, low temperature and closed storage methods must be adopted.

2.Grain storage

If the number of seed storage is large, this method is mostly used.The key is to reduce the moisture content of the seeds to less than 13 %.After the corn is decarned, the sun is dry and the warehouse is closed.During the storage period, the inspection of seed temperature, moisture and insect pests is strengthened. Once the phenomenon of fever, mildew, sweating, knotting, buds and insects should be taken in time, measures should be taken in time.At the same time, according to the weather and seed storage, ventilation and ventilation in time, and the seedlings must be carried out if necessary.

Two, Wheat

1.Heat in the warehouse storage

This is a storage method adopted by the heat resistance characteristics of Wheat, which has a good effect on insecticidal and promoting seeds.The method is simple and is not limited by the number of seeds.Specific methods: In the sunny weather, the Wheat seeds were exposed to reduce the water content below 12 %. The seed temperature reaches above 46 C but does not exceed 52 C. It lasts for two hours. Then quickly put the seeds into the warehouse while it is hot.And cover 2 to 3 layers of closed insulation, keep the seed temperature between 44 and 47 C. After 7 to 10 days, the sack was lifted and the ventilation temperature was performed until it was the same as the warehouse temperature, and then storage and storage were kept closed.

2.Pottery tank or altar storage method

This storage method is suitable for the storage of a small amount of Wheat species in farmhouses.That is, after washing the cylinder or altar to dry the sterilization and extinguishing insects, first put a certain amount of dried grass and wood ash on the bottom of the cylinder.The newspaper, the newspaper is strictly covered with a dry gray of about 10 cm thick, and then covered with sealing.Prevent moisture and insects during storage.

Third, rice

1.Warehouse storage method

This method requires that the seeds of the seeds are below 14 %.Before entering the warehouse, the board was put in the library, and a layer of grass curtain was spread on the board, and then the seeds were put in the seeds.The temperature of the warehouse is required to keep a stable state to avoid cold and heat.

2.Cellar method

This method is separated from the outside world, and the temperature and humidity change are small, which is not only suitable for storage of rice species with good maturity and low water content, but also for seeds with a little maturity and slightly high water content.The specific method is as follows: Choose a high -dry place, dig a long Square cellar, the depth of the cellar is 1.5 to 2 meters, and the width is not more than 2 meters.The rice seeds are covered with a mat, and then cover the soil for 30 to 60 cm. In early November, the seeds entered the cellar. When the temperature reached 0 to 2 C in April the following year, the seeds were removed.After the temperature rises in the spring, dry it in time to prevent the seeds from fever and deterioration.

Four, soybeans

Due to poor heat conduction of soybeans and prone to change at high temperatures, low temperature and closed storage methods should be adopted.Specific method: After the soybeans are designed, dry the air and dry in time, and control the seeds of the seeds below 12 %.After drying, spread out the cooling first, and then batch the library in batches.In addition to the closed doors and windows, the grasshopper or sacks that can be cleaned and disinfected by the bulk seed pile can also be placed through the clean and disinfected treatment. The cover should be flat, tight, and solid. This method can not only prevent moisture and insects.About 3 to 4 weeks after entering the warehouse, it should be carried out in time, ventilation, ventilation and wetness, and removing miscellaneous sieves to prevent abnormal conditions such as sweating, moldy, and red change.For farmers to store a small amount of seeds, you can use appliances such as glaze, altar tanks, or wooden boxes. The lower and upper parts are paved with some plants ash or dry sand and then closed. During the storage, it is mainly closed. However, it should be paid to timely ventilation.

Five, sorghum, valley

Select the seeds before entering the warehouse to remove impurities and batch grains.The specific method is as follows:

1.Ears storage method

When you choose spikes in the field, leave about 30 cm long stems, bundle small bundles, and hang it in the warehouse after drying.

2.seed

Several crop seed storage methods

Granular storage method

The seeds that have been descended must be dried enough to reduce the water to the safe water content (sorghum: below 13 %; valley: below 12.5 %), and store at low temperature densely.If the seed temperature is below 25 C, it can be safely stored. If the seed temperature exceeds 25 C, the seed water should be appropriately reduced.If the seeds enter the library, if the temperature decreases, it should be ventilated and cooling in a timely manner to prevent exposure.Pay attention to checking the moisture and fever of the seeds during storage.

Six, cotton

The cotton shell is hard, with short velvet on the surface, such as a large pile of storage, closed in the pile, short velvet and moisture. Due to the harvest of different periods, the maturity, and the water content of the water are different. ThereforeStorage after tie, it is best to use the frost before planting.The seeds are fully dry, and the water content is less than 12 % to enter the warehouse. It is suitable to control the height of the seed stack. It is advisable to ventilate and ventilate.Measurement.

In addition, during the storage process, new and old seeds cannot be stored together. Different crop seeds must be strictly prevented from mixed, and they cannot be mixed with Chemical Fertilizer pesticides. During the storage period, we must maintain relatively constant temperature and humidity, strengthen management, check regularly, find problems, find problems, and find problems.Take timely measures and solve it.

What are the seed preservation methods

1.

It is to store dry seeds in a dry environment, so that the seeds are often kept in dry storage during storage.In addition to drying the dry environment, it also needs to be combined with low -mild sealing conditions. This method can be adopted for seeds with low safe water content.

1, Ordinary Dry Tibetan Method

Usually storage of warehouses or basement in production.As long as the seed storage period is short (most1A), The safety water content is low and the germination ability will not be quickly lost in natural conditions, and it can be stored in a dry warehouse or in the basement.Some tree species mainly include fir, cedar, pipeline, locusting, oil pine, stinky, Hehuan, and cricket trees.The law is simple and easy to do, and the cost is low.The specific method is to put the seeds that have been properly dry and have reached a safe water content, put in a container (such as cloth Bags, sacks, barrels, boxes, etc.), and put them in storage rooms, cellar with low temperature, drying, and good ventilation., In -basement.It is necessary to check regularly during the storage. If the seeds are found to be hot, humid, and moldy, effective measures such as ventilation, dryness, stalling, and turning the warehouse should be taken immediately.

2, Low -temperature drying method

Place dry seeds in0~5, relative humidity is50%~60%storage under the conditions so that the life of the seeds can be kept1AThe above, but the seeds are required to be fully dry.To meet the standards of low temperature storage, there are generally special seed storage rooms or temperature -controlled and wet seed libraries.

3.

After loading the seeds into the container, seal it to isolate it from the external air, no gas exchange, and not affected by the changes in the humidity of the external environment.seeds (Yang, Liu, Elm, Sang, etc.) and precious seeds that need to be stored for a long time can be sealing and drying. This method is the best effect.The specific method is to put the seeds into the seal container and place it in0~5In the environment of .If the seeds are not large, use glass and other transparent containers to make it easy to observe the change of the seeds.To prevent the seeds of the seeds from rising, the desiccant must be placed in the seal container.Commonly used desiccants include: color -changing silicone, calcium chloride, charcoal, etc.seeds with low safe water content are the best storage effect with this method, but this method is not suitable for high moisture content seeds.

4, Super dry storage method

Also known as the storage of ultra -low moisture content, refers to the reduction of seed water content to5Below, a method of storage of seeds under the condition of room temperature or lower than room temperature after sealing.The effect of super dry treatment and low temperature storage is consistent, such as short -lived elm tree seeds, naturally stored1~2The month loses the germination power, and the super dry treatment reduces the moisture content of the seeds to2%Below, store at room temperature3The vitality of the month is still very high.Most seeds with low water content can be stored over dry storage, but different types of seeds have different degrees of dryness.Fat seeds have strong dryness and can be stored in super dry; starch and protein seeds have a large degree of resistance to dryness.The seeds are not dry and better, and there is a critical value of a super dry moisture.When the moisture content of the seed is lower than the critical value, the seed life is no longer extended, and dry damage occurs.The critical value of different seeds of different seeds is different.3%~5%The best moisture content of Eucommia seeds is super dry.3.5%~4.5%Essence

Second, wet Tibetan method

Put the seeds in a moist, moderate low -mild ventilation environment.Most of the seeds with high water content can be used in this method, such as: chestnuts, crickets, walnuts, etc., the temperature during wet hidden is best0~3Around .

1, Outdoor burial

Choose the width of high terrain, loose soil, good drainage, and backwind1~1.5MThe pit, the length is determined by the number of storage seeds. The depth requires below the soil frozen layer. Put some stones in the pit first, about the height10cmLeft and right, then spread some wet sand on it, the thickness is4CMOn the left and right, put the storage seeds on it, the seeds are placed on the ground10~20cmBy the time, it is covered with wet sand, and the soil is piled into a conical shape beyond the ground surface.10cm, Insert a pore bamboo Tube from the center of the pit to the bottom of the pit (for ventilation).The temperature and humidity in the pit are often checked, such as chestnuts, begonias, Du Li, etc. This method is well stored.

2, Indoor stacking method

The same is the same as the Outdoor burial. It is just sprinkled with water in the warehouse or the basement of the basement, and then supplemented by wet sand. The seeds are mixed with wet sand and stacked.

1. The life of the shade net is a few years

The service life of the Shading net is mainly related to the production materials, the environment, and the method of use. Generally speaking, the service life of the shade net ranges from 3 to 5 years, but if the production materials of the shade net are poor or the environment is harsh, then the environment is harsh, then then the environment is harsh.The service life of the shade net will be reduced a lot.

The Shading nets on the market are mainly divided into two types of production materials, one is the raw material is high -density polyethylene, and the other is the melting plastic particles melted with the two -recovered waste plastic and Shading net.And regeneration.The Shading nets produced by native materials are light, strong, strong, and durable. The service life is generally three to five years, and the price is slightly more expensive.The use of the Shading net produced by regeneration is only one to two years, and it will often be damaged after one year.

The service life of the shade net is also related to the environment and the method of use.The same Shading net will have a longer service life in the north than the life of the south. This is mainly due to the hotter weather in the south, and the sun radiation of the shade net is stronger.The internal network life of the shade net is longer than the life of the external network. The time exposed to the sun and the sun radiation intensity of the received will also affect the service life of the shade net.

Therefore, when you buy a Shading net, if you want good quality shade nets, do not greedy to buy a Shading net for cheap buying regenerative materials, resulting in a shorter service life, which will not achieve the expected results and suffer losses.

2. How to maintain a sunny net

1. Because the Shading net is made of polyester material, the texture is soft, Smooth, and durable. Therefore, it is necessary to pay attention to preservation when using a Shading net. Proper collection storage can extend the service life of the shade net, so as to achieve the purpose of multiple uses.Essence

2. When collecting the Shading net, it is best to choose it on a cloudy day, lay the net on the ground, and roll it up after drying.If there is water stains on the shade net, you need to wait for the water stains to be dried and then roll up.

3. It is important to note that the Shading net should avoid soil pollution as much as possible. If it is contaminated, it can be cleaned with a sprayer and put it away after drying.

4. Finally, the shade net should be stored in ventilation, avoiding the light, and on the shelf, pay attention to the antids and mouse bite.In this way, the Shading net can be used for a longer time.
