How to Grow Black Peanuts? A Full Breakdown of the Latest Planting Methods
Black peanut is a type of colored peanut, also known as selenium-enriched black peanut. Black peanuts contain trace elements such as iron and zinc, as well as various vitamins and amino acids. Their nutrient content is higher than that of ordinary red-skinned peanuts, making them a very popular new peanut variety. They are now gradually being grown on a larger scale in our country, so how should black peanuts be planted? Below, the editor brings you the planting methods for black peanuts. Let's take a look!
1. Site Selection and Land Preparation
Black peanuts have relatively strong adaptability and do not have great demands on soil. However, if you want to grow high-yielding black peanuts, you still need to choose soil with a pH of around 6, deep soil layers, high vitality, fertile texture and good drainage and irrigation. After selecting the land, plow deeply 28 cm to improve soil permeability and remove harmful substances such as herbicide residues left in the soil. Strengthen the soil's water and fertilizer retention to promote root growth and germination of black peanut seeds. Then apply enough base fertilizer, mainly farmyard manure, with the amount controlled at 2800 kg per mu.
2. Timely Sowing
After preparing the land, select seeds that are free of external injuries, free of pests and diseases, high-yielding and vigorous in growth, and carry out seed dressing. Use agents such as phoxim and carbendazim for seed dressing, which can effectively prevent insect pests and diseases such as stem rot. Black peanuts are usually sown in spring, using hole sowing. When sowing, pay attention to sowing density, keeping row spacing at about 38 cm and plant spacing at about 18 cm. Place 1-2 seeds in each planting hole. If the temperature is too low when sowing, cover with film in time to raise soil temperature, keep warm, and promote seed germination and emergence.
3. Water and Fertilizer Management
⟦NL>Black peanuts have relatively high nutritional needs. In addition to applying enough base fertilizer before sowing, later topdressing should also be carried out according to the growth of the black peanuts and the fertility of the soil. The number of topdressings throughout the growth period should be about three times. The first is before flowering to promote plant growth and increase the flowering rate. Then apply another topdressing after flowering, and properly apply foliar fertilizer after the black peanuts enter the expansion stage. Topdressing should mainly be compound fertilizers such as nitrogen, phosphorus and potassium. Black peanuts are not tolerant of waterlogging, so we must control watering, especially avoiding standing water in the field during the pod-setting stage. Otherwise, the pods will rot and various pests and diseases will be triggered. However, during the pegging stage, the demand for water is relatively high. During this period and in dry conditions, pay attention to timely watering.
4. Pest and Disease Control
Pest and disease control in black peanuts is very important. If poorly managed, the entire field can be damaged, resulting in no harvest at all. Common pests and diseases of black peanuts include aphids and black spot disease, so we must do a good job in pest and disease control. Follow the principle of giving priority to prevention and combining prevention with control. Strengthen field management and do a good job in watering, fertilizing and cleaning the field. During periods of high incidence of pests and diseases, spray and disinfect regularly, and frequently inspect the peanut field so as to detect and treat problems early. Avoid unnecessary economic losses.
The above is a brief introduction to black peanut planting methods. During the process of growing black peanuts, we should also do plant adjustment work such as pinching off growing tips and removing leaves. Prevent excessive vegetative growth, which affects flowering and pod setting of black peanuts and reduces yield. Also, control the harvest time according to your own planting time and variety, because harvesting too early or too late will have a certain impact on the yield and quality of black peanuts.
