Why peanuts should be mulched early for early sowing, corn should be soaked before sowing, and soybe

Peanut early sowing should be covered with mulch: mulch film is mainly to increase the temperature, to reach the temperature required for seed germination, so that it grows earlier.

Plough the soil before sowing soybeans:

The important role of tillage in agricultural production is that it can change the compact soil layer at a certain depth into a loose and fine cultivated layer, thereby increasing the porosity of the soil, which is conducive to receiving and storing rainwater, promoting the conversion of potential nutrients in the soil into effective nutrients and promoting the extension of crop roots; Crop residues, weeds, and fertilizers on the surface can be turned into the soil to clean the surface of the tillage layer, thereby improving the quality of land preparation and sowing.

Soaking corn before sowing is an economical and simple measure to increase yield, which can generally increase yield by about 10%.

1. Corn soaking method:

There are many methods of corn soaking, such as: cold water soaking, warm water soaking, active water soaking, magnetized water soaking, fresh human urine solution soaking, rice vinegar soaking, potassium dihydrogen phosphate soaking, zinc fertilizer soaking, triasanol soaking, etc. However, the most common method is to put half boiling water and half cold water in a small jar, large pot or other container, and then put the seeds inside.

The water surface should be 20-25 cm above the seeds. At the same time, it is necessary to constantly stir with a wooden stick to make the seeds evenly heated. The temperature of the water should be controlled at 25-28, and the water should be heated to heat up when the water temperature is reduced, so that the seeds should be soaked for 2-3 hours, and when the seeds absorb water and expand, they should be immediately fished out for germination treatment.

Second, corn soaking should be precautioned.

Regardless of the soaking method, the following should be noted:

1. The soaking time should be flexibly controlled. The seeds are plump, hard-grained seeds, and the soaking time should be appropriately longer. Grain seeds, horsetooth seeds, soaking time is shorter.

2. After soaking, the seeds must be dried in a cool place, and then they can be sown or dressed, otherwise it will cause pesticide damage.

3. The soaked seeds should not be exposed to the sun and should not be piled into large piles to prevent "covering the seeds".

4. In the case of dry weather, bad moisture, and no watering conditions, it is not advisable to soak the seeds, so as not to cause the germinating seeds to appear "dry buds" and not emerge.

5. Fresh human urine should be used when soaking seeds with human urine, and the soaked seeds should be sown in time.

Hello, mulching is to raise temperature, soaking seeds is early seedling, and deep turning is loosening soil.

The time of peanut cultivation should be determined according to different regions. The suitable sowing date is mid-February and mid-March in the south, the suitable sowing date in the Yangtze River basin is in late March and late April, and the suitable sowing date in the large peanut and flower producing areas in the north is late, from April to early May. The general growth period of peanuts is 100-150 days.

Peanuts are generally planted when the average ground temperature is above 12. Peanuts can be planted after the Qingming Festival.

1.When planting peanuts, the temperature should not be too low. In the south, it can be done in March in the spring and July-August in the fall.

The climate in the north is relatively cold, so it is advisable to plant seeds in April-May. If you want to sow in advance, you need to cover it with plastic film after sowing, and you can't sow it in the spring when it's cold. Spring peanuts should be planted around April 20-25.

Peanuts are best sown between mid-to-late March and early April. Peanut planting is generally sown before the rain after the Qingming Festival, and the ground temperature can be stable at more than 8 degrees.

2.Peanut roots and plants sown with mulch in the spring will also grow well. During the flowering and pod-setting stage, peanuts help to increase the pod-setting rate and increase the yield.

Another benefit is that the self-resistance of peanuts sown at this stage is enhanced, and the damage of pests and diseases will be relatively reduced. Peanut farmers cooperate with scientific management, which creates a very favorable foundation for the final high yield and high quality of plastic film peanuts. Try not to plant cover peanuts in soil that is too heavy, other textures of soil can be planted with peanuts.

The sandy loam soil with high loose fertility is the best, so that the pods of peanuts are better developed, the peanut shell is good, and the fruit shape is large.

3.In the process of land preparation, fine ridges are needed to ensure that the ridges have enough moisture. At this stage, the ridge should not be too high.

When the ridge is too high to cover the film, there will be the phenomenon that the lower cover of the ridge slope is not tightly pressed, and it is easy to scratch the film, reduce the thermal insulation and moisturizing effect, and reduce the peanut fruit needle to penetrate the soil. Quantity. Before mulching, the ditch needs to be cut up and down, to ensure that the slope section is rectangular, and the upper and lower sides are close to vertical, so as to prevent the trapezoids on both sides from moving along the shed and tilting.

After the peanut seedlings emerge, it is necessary to do a good job in the seedling inspection, and the seedlings should be replenished in time 3 to 5 days after the emergence of the seedlings. Ensure that the number of seedlings per unit area reaches the planned number, and directly germinate and replant through replanting. During the flowering and podding stages, peanuts require relatively large amounts of water.

Lack of water can cause peanuts to suffer from drought at this stage, which gradually affects flower bud differentiation, flowering, fertilization, fruit needle elongation and pod development.

They can be planted in the summer, because they just need to be warm, and they don't need mulch at this time, because they don't want to be too hot.

The suitable sowing time for peanuts in the south is from February to March, the Yangtze River basin is mainly planted with spring peanuts and summer peanuts from March to April, and the peanuts in the north are sown in April and May, and the specific time is determined by the environment and climate of the planting place. Mulch can be used during the sowing phase.

It should be planted in the summer, because it will ensure that the land receives enough nutrients to allow the seeds to grow faster.

It is planted in October and needs to be mulched, because peanuts are very easy to grow smaller and smaller when they emerge.

Mulching peanut cultivation has the effect of increasing soil temperature, waterproof, rainproof and solidifying soil, improving soil physical and chemical properties, enhancing soil organic matter and nutrient use, etc., generally more than outdoor cultivation of peanuts can increase the yield by about 30%, especially in our local area, because mulching cultivation can significantly make peanuts sold in advance and enhance economic benefits, so it is generally planted in spring when planting peanuts with mulching and cultivating. The mulch film covering peanuts is determined according to the solar terms. Take the Jiaodong area as an example, melon seeds are planted in the spring equinox, so that peanuts are also like this in this solar term.

I usually build the peanut ridge at the beginning of April with a micro-tiller, the ridge is 90 cm wide, and the fertilizer is applied to the ridge together until the spring equinox when only precipitation occurs. Mulching peanuts can be planted first and then mulched, or they can be mulched and then planted, but for the water is very poor, long-term drought or early planting of the field should be sown first and then the mulching should be eliminated. The deep planting depth is generally shallower than that of open field cultivation, and usually 3 cm is the most suitable.

Mulching cultivation should ensure sufficient moisture planting, otherwise it should be planted after watering, so as to ensure the quality of sowing. Peanut mulching is more inconvenient than bare sowing relative finch crying posture when planting, but it saves the links of tree clearing, hoeing and soil loosening, which is generally less time-saving than bare sowing. Mulching not only further increases the production volume, but also reduces the product cost and significantly improves the economic benefits.

According to the statistical analysis of several comparative tests in China's factory area, the average yield of pods per mu of peanuts planted under plastic film cover is higher than that of 1 mu without naked sowing, and the yield increase rate is. After deducting the cost of 4kg of plastic film and herbicide, a total of 30 yuan, 1 kg of pods is calculated at RMB1, and 1 mu has a net income.

Therefore, the gestation process of peanuts cultivated under plastic film cover is greatly shortened, so that the first flowering period is earlier, the needle is early, and the flowering period is infiltrated and concentrated, which promotes maturity and increases yield. At the same time, the middle and late stages of peanut gestation are of course the high temperature period, the population coverage rate is expanded, the solar radiation heat can not directly reach the road surface to be absorbed, coupled with the impermeability of the agricultural mulch film, isolating the vaporization heat to erode downward, playing a role in temperature control, and relatively maintaining the most suitable temperature for peanuts in the continuous high temperature season.

Mulching cultivated peanuts can be sown 10-15 days before the local final frost, according to a certain plant row spacing, and then mulching can be done.

Mulch film to cover peanuts, generally choose in the early spring of each year in March to April, this time should pay attention to the mulch, so that the flowers can grow better.

Generally speaking, like socks tour in our northern region, most of the bridge is destroyed in the final frost period 10-15 days before the final frost period, the ground temperature of 5 cm under the plastic film reaches about 15, which can meet the temperature requirements of peanut germination and seedling, and the final frost has passed after the emergence of seedlings, which is conducive to the robust growth of seedlings.

Therefore, the cultivation of peanuts can be sown 10-15 days before the final frost of the local area, according to a certain plant row spacing, and then covered with plastic film.

The mulch covering of peanuts is determined according to the season. Take the Jiaodong area as an example, the spring equinox melon seeds, so that the peanut kernels are also like this in such a season. Usually at the beginning of April, the peanut ridge is built with a micro-tiller, the ridge is 90 cm wide, and chemical fertilizer is applied to the ridge together, until the spring equinox only needs to encounter precipitation to plant.

Garlic planting organic sowing and artificial planting two methods, I generally use artificial cultivation planting, artificial planting with the peanut spacing of the plantation is evenly proportioned, deep ploughing, so that after the peanuts come out, the seedlings are full of seedlings, and the yield is harvested.

Mulching peanut kernel planting has the effect of increasing soil temperature, waterproof, rainproof and soil consolidation, improving soil physical and chemical properties, enhancing soil organic matter and nutrient use rate, etc., generally more than outdoor planting peanuts can increase the yield by about 30%, especially in our local area, because the subfilm planting can significantly make peanut kernels sold in advance and improve economic benefits, so peanut kernels are generally planted in spring when using mulching cultivation. The suitable sowing date of peanut covered with plastic film is based on the fact that the final frost period has passed after planting and budding. Because of the effect of plastic film mulching, the soil temperature gradually increases, so the sowing date of agricultural mulch film and covering peanuts can be earlier than that of spring peanuts cultivated in open field.

In some areas of Henan Province, Shandong Province and Hebei Province, the suitable sowing date of peanut covered with plastic film is generally on April 10 25. Select pure white membrane, this membrane has good light transmittance, fast warming of the soil layer, and the level of water retention and soil consolidation is relatively strong, which is beneficial to the change of physical and chemical characteristics of the soil layer, helps the growth and development of rhizomes, and also helps the reproduction of soil microorganisms, promotes the absorption and application of nutrients, so as to store melons to mature and increase yield. The high temperature under the film is not conducive to the growth of wild grasses.

Do not have conjunctivitis in the middle and late stages of growth. Just after harvesting or receiving, it is more difficult to pick up the old agricultural mulch film in the field.

The soil in the fruiting layer underground is loose and permeable, which is conducive to irrigation in the field, reduces the probability of rotten fruits, and is convenient to carry out when feeling. However, the main disadvantage is that the root is very easy to lack water and lose moisture, the gap between the ridge rows is large, and the relative density per mu cannot be guaranteed. Generally, the plots with thick cultivated soil, convenient irrigation in the field, and high soil organic matter are more suitable for ridge planting. Regardless of the north and south, the peanut kernels covered with sub-film have a higher and stable yield than the naked sowing of peanut kernels.

According to the statistical analysis of planting experiments for many years, the yield of pods per mu is higher than that of 1 mu of open sowing, and the yield increase rate is 44%. Therefore, in China's peanut kernel factory area, more than 80% of the peanut fields are cultivated with plastic film mulching.

It should be determined according to the local environment, under normal circumstances, it is sown at the time of charging, and the appropriate thickness of plastic film can be selected for use.

The best sowing time for peanuts is in February in early spring every year, although the ambient temperature is low at this time, but the temperature in the soil can be increased, which is conducive to peanut germination and rooting, and can improve the yield of plants.

A look at the certificate and production date: when purchasing plastic film, not only to see the product certificate, but also to see the shelf life, the effective quality assurance period of agricultural film is 1 year, try to buy the plastic film closer to the consumption date. Because the agricultural film will be aged after a long period of storage, it will shorten the service life and lose its due protective hail selling effect.

Sowing is ready in February. It is best to choose white mulch, which can be well insulated and can improve the yield.

It's more suitable in March. It is best to choose a pure white mulch, which has very good light transmittance.

The time of planting agricultural film peanuts is dominated by spring peanuts, and the advantages of spring ploughing agricultural film peanuts depend on the corresponding increase in germination rate. Secondly, the peanut rhizomes and plants will grow well in spring ploughing, and the peanut is conducive to increasing the pod setting rate and increasing the total yield in the full blooming and pod-setting stage. Another advantage is that the peanuts planted in this link have improved resistance and a relative reduction in disease damage.

Peanut growers cooperate with each other with scientific and reasonable management methods, which can create a very beneficial foundation for the final increase in yield and high quality of peanuts with agricultural mulch. The climatic conditions of farming are different, therefore, the sharing of rural red plum blossoms refers to the sowing time in the Jiaodong area. In the Jiaodong area, it is generally around May Day, because most of the temperature in this case is suitable for sub-film planting, although the soil temperature is not high enough, but the peanuts are planted in the ground, covered with agricultural mulch, can be insulated and insulated.

You need to look at the weather conditions, as long as it rains around May Day.

Everyone will grasp the seedling situation and gradually plant peanuts covered with sub-membrane. The duration of peanut planting is generally in spring, and the weather in spring is extremely unstable due to high and low temperatures. This results in strong winds and cooled temperatures.

The damage caused by the strong winds to the agricultural mulch film is obvious. For example, after we planted the peanuts, we covered them with agricultural mulch film and did not bury them firmly, then the wind would blow the agricultural mulch film apart, blow up, or even blow it completely. Once the mulch film is destroyed, the peanut seedlings will freeze and crack due to the deterioration caused by the wind, which will affect the overall harvest.

Once it is found that the agricultural mulch film has been blown off, it should be quickly covered with a new film, and compacted to ensure the temperature and humidity of the land resources. The management method of covered peanut should do a good job in several aspects, the first in the seedling excavation export, to timely cut the film and cast the seedling, the film is generally selected in the area where the seedling can not be fully automatically broken and excavated, and the seedling should be released by artificial film breaking. Generally, the film is selected at 9-10 o'clock in the morning when the temperature is warm, and the moderately cultivated soil will be pressed after the film is opened to prevent the outflow of water and nutrients, which is beneficial to maintaining the soil temperature.
