Planting techniques of Peanut

Peanut is one of the most important cash crops in China. Peanut is planted in all regions of China. With the improvement of planting technology, peanut yield is constantly breaking through, and economic benefits are getting higher and higher. So how do peanuts grow? Let's take a look at 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 relatively loose loam planting. However, it is not suitable for continuous cropping, so that the organic matter content of the soil is low, and the damage of diseases and insect pests is also serious. After selecting the soil, it will be deeply turned 3-4 times to make it fully mature and loose. In the application of base fertilizer, generally apply decomposed farm manure 2000-300 kg per mu, or apply 300 kg 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 larger size when selecting seeds, and sow them after drying. When sowing, generally adopt the method of hole sowing, open holes according to the row spacing of 20×40 cm, put 3-4 seeds in each hole, and cover a thin layer of soil after sowing. In order to promote the growth of seedlings, you can sprinkle 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 for insulation to make it sprout quickly.

3. Thinning and replenishing seedlings

When the seedlings are just unearthed, check them 1-2 times a day in time. When the seedlings grow neatly, they should start thinning and replenishing seedlings. If there are missing seedlings, they should be replenished. If the seedlings grow too densely, they should be thinned in time, and the seedlings that grow too densely should be transplanted to the missing seedlings. This makes the seedlings evenly distributed, the yield will also be improved, and the seedling growth will be accelerated.

4. Fertilization

Peanut is a fertilizer-loving crop. To achieve high yield and excellent yield, fertilization is essential, especially calcium, sulfur and other fertilizers. During the fruiting period, attention must be paid to the application of calcium and sulfur fertilizers. At the same time, attention should be paid to supplementing boron and molybdenum elements to ensure sufficient nutrition for peanuts and promote their growth. Generally, gypsum is applied 10-15 kg per mu, generally applied 15-25 days after flower needle is buried; 0.2% borax solution can be sprayed 45-65 kg per mu at the initial flowering stage; 0. 1% ammonium molybdate solution 50kg foliar fertilizer spraying 1-2 times.
