Planting technology of pollution-free healthy black peanut

July 27, 2021

Black peanut is a new variety rich in selenium, iron, zinc and other trace elements and melanin. It contains nutrients such as calcium, potassium, copper, zinc, iron, selenium, manganese, 8 vitamins and 19 amino acids required by the human body. Compared with red peanuts, black peanuts have 5% higher crude protein content, 23.9% higher arginine content, 19% higher potassium content, 48% higher zinc content, and 101% higher selenium content. Because black peanuts are rich in selenium and other trace elements, they play a good role in maintaining human growth and development, body immunity, and cardiovascular and cerebrovascular health.

1. Planting plot selection:

Choose plots where the air, soil, and water sources are not polluted in any way.

2. Soil selection:

Don't choose too fertile land, oil sandy land is the best. The terrain is required to be flat and convenient for irrigation and drainage.

3. Cultivation time:

It can be planted from early March to early May.

4. Seed treatment:

Seed in the sun for 3 days before peeling. After peeling, remove the kernels that have pests, germs, damage and can not be used. The rest are divided into large and small seeds and sowed in grades. It is not advisable to mix seeds of different sizes. Use 9 kg-10 kg of seeds per 667 square meters. Soak the seeds with 15 kg of water for 3 hours with "Bio-Ling" nutrient solution to increase the nutrient content of the seeds. At the same time, use 50 grams of dimethoate for seed disinfection. Before sowing, 400 grams of carbendazim was used for soil disinfection per 667 square meters.

5. Planting method:

Drill sowing, row spacing 30 cm; hole sowing, spring sowing, 9497 holes per 667 square meters, row spacing of 39 cm × 18 cm; summer sowing 11900 holes per 667 square meter, row spacing of 35 cm × 16 cm, 2 hole sowing Seeds.

6. Reasonable fertilization:

2,000 kilograms of bio-fermentation compost, 10 kilograms of urea, 35 kilograms of phosphate fertilizer, 30 kilograms of potassium sulfate, 0.5 kilograms of boron fertilizer, and 1 kilogram of zinc fertilizer are used as base fertilizer; Prevent ants. Top dressing: Spray 25-30 ml of Chlormequat at the 3-4 leaf stage, spray once every 7 days for 3 times. In the early stage of flowering, spray 15 kg of water each with "Bio-Ling" nutrient solution, spray once every 10 days, and spray 3 times in a row. Cover the base of the plant with soil during the blooming period to prevent the roots from unearthed, and spray "Bio-Ling" nutrient solution 7 days later.

7. Weeding:

Before sowing, use 700 grams of acetochlor for every 667 square meters to spray the ground with water, or use 75 ml of 50% acetochlor EC to spray the ground evenly with 100 kg-150 kg of water. In the 2-3 leaf stage of peanuts, spray 100 grams of water per 667 square meters on the ground. Finally, artificial weeding is carried out.

8. Pest control:

5% Jinggangmycin can be sprayed with 2000 times liquid to prevent and cure wilt during the peanut seedling stage. For virus-transmitting aphids, when the peanut ground aphid plant rate reaches 5%-10%, use 10% imidacloprid wettable powder 3000 times or 40% dimethoate emulsion 1000-1500 times to spray for control. For brown spot, black spot, anthracnose, etc., use 50% carbendazim wettable powder 1000 times or 80% mancozeb wettable powder 500 times to prevent and control, every 7-10 days 1 Times, spray 3 times in a row. When the leaves turn yellow during the growth period, the roots should be checked in time, and it is found that 50 grams of Guoguang Root Rot per 667 square meters is sprayed 3-5 times with 15 kg of water. To prevent and control ants, use potassium chloride powder and base fertilizer together.

9. Field management:

Peanuts need a lot of water during the flowering and pod-setting phases. In case of drought, they should be watered in time. Peanuts are afraid of waterlogging. In rainy seasons, you should pay attention to waterlogging, especially during the pod-setting period to prevent waterlogging to prevent rotten fruit.

10. Harvest at the right time:

The middle and lower leaves of the plant fall off normally, and the seed coat is harvested when the seed coat is pink. Dry in time after harvest to prevent mildew.
