1.Plot selection: Black peanuts are not strict with the soil requirements, and the best suitable for various soils with PH5.5-7.2 is the requirement of drought-irrigated, alfalfa-energy-absorbable, plough depth of 30 cm or more, and organic matter content of 0.5%- 1.0%, preferably in raw land, implement rotations and try not to repeat them. 2. Pay attention to basal fertilizer: Spring sowing requires deep plowing 25 to 30 centimeters in winter, and ploughing 2500 to 3,000 kg/mu of organic fertilizer, and 10 to 15 centimeters of shallow tillage before planting in the following year. When planting ridges, apply 50 kg/mu of potassium sulfate compound fertilizer+10-20 kg/mu potassium dihydrogen phosphate+50 kg/mu phosphate fertilizer+5-10 kg/mu urea, mainly applied between peanut piers and piers. At the time, it must be sowed and fertilized after pouring enough water in the sowing ditch. At the same time, planting 50% phoxim + 0.5% carbendazim 500 times solution in the trenches to prevent peanut stem rot, root rot and other diseases. 3, improve the quality of sowing: ridging: to promote ridging planting, ridge spacing 30 to 40 cm, ridge width 55 to 60 cm, ridge height 10 to 15 cm, double row planting, spacing 25 cm, hole spacing 15 cm, sowing Depth 5 cm, sowing rate 8500 ~ 10000 points / acre, sowing 2 per hole. Seed treatment: It is required to choose double-grained fruit, drying it with shells for 2 to 3 days before shelling, and screening first-grade healthy rice as a seed after shelling, promoting seed dressing with rare earth or seed coating agent, and applying seed dressing per kilogram of seed. 2 grams of borax + 2 grams of rare earth, can significantly improve the yield and quality. Film mulching: Immediately after sowing in early April, spray 50% acetochlor on the soil to close the weeds with a dosage of 100 ml/mu. The requirements are uniform and comprehensive, followed by covering with a black mulch, and the ridge surface is flat and the membrane is tight and moderate. Both sides of the membrane are compacted with a ditch soil. 4, to strengthen field management: broken membrane seedlings: When the peanut seedlings exposed 2 to 3 true leaves, broken holes in time to break the membrane will be the cotyledon up above the membrane surface, requires 2 to 3 batches, in the morning or evening, It is forbidden to implement it at noon, and then seal the membrane hole to seal it to keep it warm and moist, so as to prevent burns and seedlings. Seedlings fill seedlings: seeding 10 to 15 days after the emergence of peanut seedlings timely inspection, found that the lack of seedlings, timely soaking seed replanting, in order to protect the seedlings full Miaowang. Appropriate cultivator, earthworms: Before the flowering and sealing, appropriate cultivator loose soil, the row of soil to the plant roots, the thickness of 20 cm, the fruit easily into the soil, combined with soil, can be appropriate fertilization. Control and prosperous: The main stem of the peanut will be removed at the beginning of the flowering period, the control will be prosperous, and the concentration of nutrients will be promoted, which will help improve the rate of results and the single fruit weight. At the same time, for those who grow seedlings, they can be sprayed with 15% paclobutrazol for 500 times. Strengthen the application of foliar fertilizer: peanuts need a large amount of fertilizer in the middle and late, should start from the flowering period, to strengthen the application of foliar fertilizer, generally every 7 to 10 days spray once, even spray 3 to 5 times, commonly used foliar fertilizer: 2% superphosphate leaching solution, 0.3% potassium dihydrogen phosphate, 0.1-0.2% ammonium molybdate, 1-2% urea, especially 30-40 days before harvest, plus one injection of 1% urea + 0.3% dihydrogen phosphate Potassium is beneficial to prevent premature aging, promote nutrient accumulation, increase production, and increase the quality of pods. Strengthen water management: In the period of pods and pods ripening period encountered more severe drought, can be watered by planting ditch small water, avoid flood irrigation, and timely shallow rake to prevent soil compaction in the ditch. When you encounter squatting, you need to timely dig trench drainage. 5, timely control of pests and diseases: black peanuts stronger resistance, fewer pests and diseases, pay attention to strengthen the prevention of rust, leaf spot and other diseases, can be used in the early onset of 20% Triadimefon 1500 ~ 2000 times, 70% thiophanate 1200 Times, 65% mancozebite 600 times, agricultural resistance 120, 200 ~ 300 times to prevent and control, interval 10 to 15 days. 6. Appropriate harvesting: Black peanuts have a large amount of moisture in the ripening period of the capsule, dehydration is slow, and the ripening period is short. It should be harvested in an appropriate period to prevent sprouting and rotting fruit. When the leaves of the upper fruit branch of peanuts turn yellow, the network of shells is clear, and the seeds are black and shiny, they must be harvested in time. The harvest is too early and the pods are not full, resulting in a reduced yield. The harvest is too late and the pods are easy to fall off. The fertility period is about 125 days. Portable Multi-parameter Analyzer Multi-Parameter Analyzer, Water Quality Analyzer, Portable Multi-Parameter Analyzer, Versatile Multi-Parameter Analyzer INESA Scientific Instrument Co., Ltd , https://www.inesarex.com Black peanut is a kind of high protein, high arginine, high selenium, high potassium, high melanin, protein, high arginine, respectively, higher than normal peanut 5% and 23.9%, potassium, zinc, selenium content were It is 19%, 48%, and 101% higher than regular peanuts. The advantage of black peanut is special nutrition. It plays an important role in maintaining the body's growth and development, body immunity, cardiovascular and cerebrovascular health care, etc. It has the functions of preventing and treating cancer, protecting the liver, protecting the health of heart muscle, preventing cardiovascular and cerebrovascular diseases, and strengthening human immunity. Anti-aging and other effects, in the health food and medical foods have broad prospects, is a very promising black food. After two years of trial planting, in the case of intercropping orchards, the average yield was 350 kg/mu, and the high-yield plots reached 425 kg/mu, with an output value of 3,500 yuan/mu or more, which was 3 to 5 times that of ordinary peanuts, and the economic benefits were very significant.
