The proportion of nitrogen, phosphorus and potassium absorbed by peanut in formula fertilization was 1.1. According to this proportion, the plots with general yield should apply high-quality soil per mu.

1. Selection of improved varieties can select peanut varieties with high quality and high yield, such as Huayu 17, Huayu 16, 8130 and so on.

2. The proportion of nitrogen, phosphorus and potassium absorbed by peanut in formula fertilization was 1.1. According to this proportion, the plots with general output should apply 2000 kg of high-quality soil miscellaneous fertilizer, 50 kg of superphosphate, 15 kg of compound fertilizer, 10 kg of urea, 2 kg of potassium dihydrogen phosphate, 1 kg of borax and 1 kg of zinc sulfate. Soil miscellaneous fertilizer, calcium superphosphate and potassium dihydrogen phosphate were combined with soil preparation, and other chemical fertilizers were combined into ridges and furrows.

3. Seed treatment: one month before sowing, the peanut was shelled and dried for 2 or 3 days. After shelling, the seeds with bright and full seed coat were selected. Before sowing, 25% crustacean seed coating agent was used, and the seed was mixed according to the drug ratio of 1: 50: 1: 70, and the seed was sown after the seed epidermis was dry.

4. Sowing at an appropriate time when the ground temperature at a depth of 5 cm is stable at 15 ℃. There should be enough moisture when sowing. The planting method of double-row ridging and plastic film mulching is adopted, the ridge distance is 85 cm 90 cm, the ridge height is 55 cm 60 cm, the row spacing is 50 cm, the hole spacing is about 18 cm, and the hole depth is 3 cm 5 cm. Sow 9000 to 9500 holes per mu and 2 seeds per hole.
