Key techniques of Peanut cultivation and Management

Soil preparation and fertilization: peanuts should be planted in loose soil, then turn deep into the soil for 3-4 times, and then sow with base fertilizer. Seed selection and sowing: seeds with full grains and large size should be selected and sown reasonably after drying. Inter-seedling replenishment: appropriate inter-seedling replenishment should be carried out after the completion of the seedlings. Reasonable fertilization: peanuts like fertilizer, and calcium fertilizer, sulfur fertilizer, boron and molybdenum should be applied together in the fruit period. Prevention and control of diseases and insect pests: pay attention to the prevention and control of rust and leaf spot, voles can be killed by trapping.

1. Soil preparation and fertilization

1. Peanuts are suitable to be planted in loose soil, while over-sticky soil is not conducive to peanut growth, nor is it suitable for continuous cropping, so the organic matter in the soil will be reduced, and the diseases and insect pests will be more serious.

2. After selecting the planting land, in order to make the soil fully mature and loose, we can turn the soil deeply for about 3-4 times, and then apply basic fertilizer, about 2000-3000 kg of rotten farm manure per mu or about 300kg of compound fertilizer.

2. Seed selection and sowing

The main results are as follows: 1. Seeds should be selected before sowing, which is beneficial to improve yield and quality. seeds with large size and full grains should be selected for planting, and the seeds should be dried before sowing.

2. Hole sowing is usually used to sow seeds, and holes can be opened according to the plant spacing 20cm and row spacing 40cm, and about 3-4 grains can be put into each hole, and then covered with thin soil once.

3. In addition, a thin fertilizer can be sprinkled on the surface, which is beneficial to the growth of seedlings. The temperature must be well controlled. If the temperature is too low, it will affect the germination rate of seeds, so it is necessary to cover a layer of thermal insulation plastic film to promote the rapid germination of seeds.

3. Replenishing seedlings

1. After the seedlings are unearthed, we must pay attention to their growth. When the seedlings are complete, we can begin to replenish the seedlings.

2. If the seedlings that are too dense need to be inter-seedlings in time, and the seedlings with deficiency should be replenished in time, so that the seedlings can be evenly distributed, which is beneficial to improve the growth rate of seedlings and increase the yield.

IV. Rational fertilization

1. Peanut is a kind of crop that likes fertilizer. In the fruiting period, in order to ensure adequate nutrition of peanut, calcium fertilizer, sulfur fertilizer, boron and molybdenum can be applied together to promote plant growth.

2. When the flower needle is buried in the ground for about 15-25 days, about 10-15 kg of gypsum can be applied per mu, and about 45-65 kg of 0.2% borax solution can be sprayed per mu in the early flowering period. during the growing period, 0.1% ammonium molybdate aqueous solution can be sprayed about 1-2 times.

V. Prevention and control of diseases and insect pests

1. The common diseases of peanut are rust and leaf spot. The rust can be controlled with 20% trimethoprim EC 30-40 ml per mu and 40 kg water per mu. Leaf spot can be controlled with 1000 times of 75% topiramate or 70-80 kg of carbendazim per mu.
