Peanut mulching peanuts in the main producing areas of Jizhongnan, Jidong and other major peanut production areas in our province, a large area, but also an important cultivation mode of peanut production. Using mulching technology to cover the ground, peanuts can be sowed earlier, yields can be increased, and the morning market can be improved, and the multiple cropping index can be increased to increase planting efficiency. Here are some points that should be noted in the production of plastic film spring peanuts. Laparoscopic Suction tube And Retractor We're professional Laparoscopic Suction Tool manufacturers and

First, choose the right soil. Peanut is a kind of oil crop that is resistant to drought and barren. It especially likes sandy land with good permeability and large temperature difference between day and night. However, pure sandy land has poor fertility and has a great impact on peanut production. The yield of spring peanuts on plastic mulch is high and the demand for fertilizer is even greater. To maximize the output of peanuts, the land for cultivating mulch spring peanuts should be the soil with fertile sandy soil.
Second, choose the appropriate variety. The growth environment of mulching peanuts is superior. The mulching film can increase the temperature of the soil where the root system is located. The mulching ability is strong, the fertilizer utilization rate is high, and the peanut root system is developed. The absorption and utilization of nutrients is also high, so the peanut production is more significant. In order to increase planting efficiency, spring peanuts covered with mulching film shall be selected from medium-to-large-fruit peanut varieties with greater potential for yield increase, and high disease resistance, such as Huanhua No.2, No.4, No.4 and Luhua11. Huayu 16, Huayu 18 and other varieties.
Third, do timely sowing. There are two types of misunderstandings in production. One is to sow early sowing and the other to delay sowing. Premature sowing of peanut mulching film is prone to freezing seedlings. Since temperatures in early spring are unstable, the temperature fluctuates, and late spring and cold waves will pose great threats to early sowing peanuts. The emergence of light but the second broken ridge, a serious defamation. 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. According to typical years, the sowing date of mulching spring peanuts is about half a month earlier than that of spring peanuts in the open season. In the central and southern parts of the province, it is generally good on April 15-20, and the eastern part of Gansu is delayed by one week.
Fourth, do a balanced fertilization. Peanut is a high-yielding oil crop and has a large demand for fertilizer. Because it has nitrogen fixation itself, the demand for nitrogen fertilizer is not very large, but the demand for phosphorus and potassium fertilizer is relatively large. In order to ensure high yields of spring peanuts for mulching films, it is necessary to ensure adequate supply of fertilizers. Organic fertilizers and fertilizers should be used in combination with each other. Organic fertilizers should be used as base fertilizers. After the seedlings are harvested, the nitrogen fertilizer is applied once to recover 15 kg of urea per acre, and 10 kg of compound fertilizer is recovered during the period of podging. Generally, 5000 kg of Mushi farmyard fertilizer and 30 kg of potassium sulfate compound fertilizer are used as base fertilizer. The application of calcium fertilizer can effectively prevent rotten fruit and black plaster spots, and increase the application of 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 pods.
Fifth, master the appropriate density. The density of cultivating spring peanuts should not be too small or too large. A small amount will affect the yield, and the result rate of excessively large single plants will decline, resulting in a waste of seeds and a decrease in yield. In the production of a common use of a film of double row cultivation mode, spacing 30 cm, spacing 15-18 cm, mu density of about 10,000 points, two per hole, acres with 16 kilograms.
