Plastic film spring peanuts are an efficient planting pattern in production. Peanuts cover the film on the ground to improve the physical and chemical properties of the soil, promote the metabolism of the crops, achieve early sowing of peanuts, resist low temperatures and spring drought, promote peanut growth, increase yield, and morning markets, increase multiple cropping index, and improve peanuts. Quality and a significant increase in preterm birth are a good way to increase the yield and efficiency of peanut cultivation. Before and after sowing spring peanuts should be done in the following aspects: First, choose the soil. Peanut is a kind of oil crop that is resistant to drought and thin, especially sandy loam with good permeability and large temperature difference between day and night. Peanut grows in the field, grows heavily and cultivating. Not only plant growth is short, but also disease is severe, which seriously affects the yield and quality. Therefore, a reasonable rotation system must be adopted. The appropriate rotation crops for peanuts are grasses, such as corn, wheat, millet and sorghum, and legumes should not be used as a former crop. The rotation period is 3-4 years. Second, choose the best species. Covering the film can increase the soil temperature, enhance the ability to maintain grasshoppers, and increase fertilizer utilization. Peanut root system developed, the absorption and utilization of nutrients is high, so the increase in peanut production is more significant. In order to improve planting efficiency, cultivar mulch cultivation should choose varieties with large yield potential, high yield, and strong disease resistance such as Luhua 11, Huayu 18 and other varieties. Third, formula fertilization. Peanut is a high-yielding oil crop and has a large demand for fertilizer because it has a nitrogen fixation and the demand for nitrogen fertilizer is not very large, but the demand for phosphorus and potassium fertilizers is relatively large. In order to achieve high yields of mulch spring peanuts, it is necessary to ensure sufficient supply of nutrients and to use organic fertilizers in combination with chemical fertilizers. All organic fertilizers were used as base fertilizers at one time. Mushi farmyard fertilizer was 5000 kg and potassium sulfate compound fertilizer was 50 kg. The application of calcium fertilizer can effectively prevent rotten fruit disease and "black plaster spots", and apply 50 kilograms of superphosphate calcium phosphate fertilizer per acre. The increase of 1 kg of boron fertilizer and zinc fertilizer can significantly increase the fruit setting rate and increase the fullness of mango fruit. Fourth, drug seed dressing. Peeling shells of peanut seeds prematurely can easily lead to a decline in seed quality. The seeds lose the protection of their outer shells, and they can absorb the harmful gases and harmful substances in the air. The activity is greatly reduced. Peel the seeds of peanuts half a month before sowing. It is better to store the peeled seeds in a woven bag and store them in a ventilated and dry place. Before and after 3-5 days of sowing, choose sunny days before and after noon, lay newspapers on the mud or cement ground, spread the peanut seeds to dry for 3-5 hours. The tanned seeds were sorted and ranked, and diseased grains, residual grains, and germinated grains were picked out. Afterwards, the use of fungicides and other fungicides for seed dressing can effectively prevent stem rot and root rot. Fifth, the safe application of herbicides. Peanuts must be sprayed with mulching peanuts before emergence after emergence. Available per acre 100-150 milliliters of cable, or acetochlor 50-75 milliliters, 50-60 kilograms per acre, sprayed on the surface before the cover film. When herbicides are selected, one must have the right variety and the second must be accurate. Only in this way can we be safe, economical and effective. Six, timely sowing. There are often two types of misunderstandings in production. One is early sowing, and peanut seeding is too early. Due to unstable temperatures in the early spring and even a cold spring or cold wave, it poses a great threat to the early sowing of peanuts. At the very least, the lack of seedlings and ridges are severe, resulting in severe deterrence. The other is delayed sowing. Delayed sowing time, the role of plastic film coverage can not be fully realized, the corresponding delay in the listing period will affect the income of growers. Seven, suitable density. The density of cultivating spring peanuts should not be too small or too large, too small will affect the yield, the result rate of excessively large single plants will decline, the seeds will be wasted, and the yield will be reduced. Starting from the first, the base is 85-90 cm wide, 50-55 cm wide at the top and 10-12 cm high. Production usually uses a double film cultivation mode. The row spacing is controlled at 30 cm, the plant spacing is 15-18 cm, and the mu density is about 10,000 holes. Each hole has two grains and the amount of mu is 16 kg.
