The latest course of planting techniques and methods of peanuts

Peanut is one of the most important cash crops in China, which is planted in all regions of our country. With the improvement and improvement of planting technology, the output of peanut is constantly breaking through, and the economic benefit is getting higher and higher. So how to grow peanuts? Let's take a look at the peanut planting techniques.

1. Soil preparation and fertilization

Peanuts like relatively loose soil, if the soil is too sticky and hard, it is not suitable for peanut growth, so it is appropriate to choose a relatively loose loam. But it is not suitable for continuous cropping, so the content of organic matter in the soil is low, and the harm of diseases and insect pests is more serious. After selecting the soil, turn it deeply for 3-4 times to make it fully mature and loose. In the application of base fertilizer, generally apply rotten farm manure 2000-300kg per mu, or 300kg compound fertilizer per mu.

2. Seed selection and sowing

If you want to plant high-yield and high-quality peanuts, you should choose seeds with full grains and large size, and then sow them after drying. The method of hole sowing is generally adopted when sowing, opening holes according to the plant row spacing of 20 × 40 cm, putting 3-4 seeds in each hole, and covering a thin layer of soil after sowing. In order to promote the growth of seedlings, you can spread a thin layer of fertilizer on the surface, and pay attention to the temperature. If the temperature is too low, the germination rate of peanut seeds will be relatively low, so it is necessary to cover a plastic film to keep warm so that it can sprout quickly.

3. Replenish seedlings with inter-seedlings

When the seedlings are just unearthed, check them 1-2 times a day in time. When the seedlings grow neatly, they should begin to replenish the seedlings, and if there is a lack of seedlings, they should replenish the seedlings. If the seedlings are too dense and time seedlings, transplant the seedlings that are too dense to the place where the seedlings are missing. In this way, the distribution of seedlings is uniform, the yield will be increased, and the growth of seedlings will be accelerated.

4. Fertilization

Peanut is a fertilizer-loving crop. Fertilization is essential for its high yield and high yield, especially calcium and sulfur fertilizers. In the fruiting period, attention must be paid to the application of calcium fertilizer and sulfur fertilizer, and at the same time, attention should be paid to the supplement of boron and molybdenum to ensure adequate nutrition of peanut and promote its growth. Generally, 10-15 kg gypsum is applied per mu, generally 15-25 days after the flower needle is buried in the soil; 0.2% borax solution can be sprayed 45-65 kg per mu in the early flowering stage; 0. 0% can be used in the growing period. 1% ammonium molybdate aqueous solution 50 kg foliar fertilizer spraying 1-2 times.
