Planting method of Black Peanut

Black peanut is a kind of colored peanut, also known as selenium-rich black peanut, black peanut contains trace elements such as iron and zinc and various vitamins, amino acids and so on. The nutrient content is higher than that of ordinary Honghuashan, and it is a very popular new peanut variety. Now in our country also gradually began to grow on a large scale, so how should black peanuts be planted? The following small series brings you the planting method of black peanuts. Let's take a look together!

1. Land selection and preparation

Black peanuts have strong adaptability and do not have too many requirements for soil. However, if you want to plant high-yield black peanuts, you still need to choose soil with PH value of about 6, deep soil layer, large vitality, fertile soil and good drainage and irrigation. After selecting the land, deep ploughing 28 cm to improve the permeability of the soil and remove harmful substances such as herbicides remaining in the soil. Strengthen soil water and fertilizer conservation, promote black peanut seeds to take root and sprout. Then apply enough base fertilizer, mainly farm manure, and control the dosage at 2800kg/mu.

2. Timely sowing

After finishing the land, select seeds with no trauma, no pests, good yield and strong growth ability, and dress them. Seed dressing with phoxim, carbendazim and other pesticides can effectively control pests and diseases such as stem rot. Black peanuts are usually sown in spring, using the method of hole sowing. Pay attention to the sowing density when sowing, and control the row spacing at about 38 cm and the plant spacing at about 18 cm. Put 1-2 seeds into each planting hole. If the temperature is too low when sowing, it is necessary to timely cover the film to increase the soil temperature, keep warm, and promote seed germination.

3. Water and fertilizer management

The nutritional requirements of black peanuts are relatively large. In addition to applying sufficient base fertilizer before sowing, topdressing should be done according to the growth of black peanuts and the fertility of soil in the later stage. The number of topdressing in the whole growth period should be about three times, the first time before flowering, promote plant growth, improve flowering rate. Then after flowering, apply foliar fertilizer again. When black peanut enters expansion period, apply foliar fertilizer appropriately. The topdressing fertilizer is mainly compound fertilizer such as nitrogen, phosphorus and potassium. Black peanuts are not resistant to waterlogging. Therefore, we should control the irrigation of water, especially in the pod setting period of black peanuts to avoid ponding in the field. Otherwise, the fruit will rot and cause various pests. However, in the next needle period when the demand for water is relatively large, this period and drought should pay attention to timely watering.

4. Pest control

Black peanut pest control work is very important, if the poor management of the whole mu damage, resulting in no harvest. Black peanut common diseases and insect pests are aphids, black spot disease, etc., so we must do a good job of pest control. Take prevention as the main principle and combine prevention and control as the principle. Strengthen field management, do a good job of watering, fertilizing and clearing the garden. In the period of high incidence of diseases and insect pests, regular spraying disinfection, frequent inspection of peanut fields, early detection and early treatment. Avoid unnecessary economic losses.

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