The latest planting method of black peanut

Black peanut is a kind of colored peanut, also known as selenium-rich black peanut, black peanut contains iron, zinc and other trace elements and various vitamins, amino acids and so on. It has a higher nutrient content than the ordinary Honghua Mountain and is a very popular new peanut variety. Now in our country also gradually began to grow on a large scale, so how to grow black peanuts? The following editor brings you the planting method of black peanuts, let's have a look!

1. Land selection and preparation

Black peanut has strong adaptability and does not require much soil, but if you want to grow high-yield black peanut, you still need to choose the soil with a PH value of about 6, deep soil layer, high vitality, fertile soil and good drainage and irrigation. After selecting the site, the soil preparation will be turned to a depth of 28 cm to improve the soil permeability and remove harmful substances such as herbicides that remain in the soil. Strengthen the water and fertilizer conservation of soil and promote the rooting and germination of black peanut seeds. Then apply sufficient base fertilizer, the base fertilizer is mainly farm manure, and the amount is controlled at 2800kg/ mu.

2. Sowing seeds at the right time

After finishing the soil, the seeds with no trauma, no diseases and insect pests, good yield and strong growth ability were selected for seed dressing. Seed dressing with phoxim and carbendazim can effectively control diseases and pests such as insect pests and stem rot. Black peanuts are usually sown in spring, using hole sowing, paying attention to the sowing density, controlling the row spacing at about 38 cm and the plant spacing at about 18 cm. Put 1-2 seeds in each planting hole. If the sowing temperature is too low, film mulching should be timely to increase the soil temperature, heat preservation, and promote seed germination and emergence.

3. Water and fertilizer management

The nutritional demand of black peanut is relatively large, in addition to applying sufficient base fertilizer before sowing, topdressing work should be done in the later stage according to the growth of black peanut and the degree of soil fertility. The times of topdressing in the whole growth period should be about three times, the first time before flowering, to promote plant growth and increase flowering rate. Then it was applied again after flowering, and foliar fertilizer was applied properly when the black peanut entered the expansion period. Topdressing fertilizer is mainly compound fertilizer such as nitrogen, phosphorus and potassium, and black peanut is not resistant to waterlogging, so we should control the watering of water, especially in the podding period of black peanut to avoid stagnant water in the field. Otherwise, it will rot fruit and cause all kinds of diseases and insect pests. However, in the needle period when the demand for water is relatively large, this period and drought should pay attention to timely watering.

4. Pest control

The prevention and control of diseases and insect pests of black peanuts is very important. If the management is poor, the whole mu will suffer, resulting in no harvest. Common diseases and insect pests of black peanuts are aphids, black spot and so on, so we must do a good job in the prevention and control of diseases and insect pests. Give priority to prevention and the principle of combination of prevention and treatment. Strengthen field management and do a good job in watering, fertilizing and clearing gardens. In the high incidence period of diseases and insect pests, regular spraying and disinfection should be done, and peanut fields should be inspected regularly to achieve early detection and early treatment. Avoid unnecessary economic losses.

The above is a brief introduction to the planting methods of black peanuts. We also have to do a good job of plant adjustment such as picking hearts and leaves on the way to planting black peanuts. Prevent the plant from flourishing and grow, affect the flowering and pod formation of black peanut, and reduce the yield. And according to their own planting time and varieties to control the harvest time, harvest too early and too late will have a certain impact on the yield and quality of black peanuts.
