Technical points for efficient cultivation and management of black peanut
How to plant black peanuts? Black peanut is a nutrient-rich peanut variety. Its content of zinc, potassium and selenium is higher than that of ordinary peanuts. According to online information, black peanut can also protect liver and protect heart muscle. Let's take a look at the key points of cultivation techniques for black peanuts. 1, plot selection Black peanuts are not strict with soil requirements. It is suitable for all kinds of soils with a pH of 5.5 to 7.2. It is required to be able to pour dry water and sputum. The depth of the plough layer is more than 30 cm, and the organic matter content is 0.5% to 1.0%. Place the land, carry out the rotation, try not to repeat it. 2, pay attention to the base fertilizer Spring sowing requires 25 to 30 centimeters of deep ploughing in winter, and 2500 to 3000 kilograms per mu of organic fertilizer. In the next year, it is necessary to shallowly plow 10 to 15 centimeters before planting, and to achieve the ridges and innocent rumors. Apply 50 kg / mu potassium sulfate compound fertilizer + 10 ~ 20 kg / mu potassium dihydrogen phosphate + 50 kg / mu phosphate fertilizer + 5 ~ 10 kg / mu urea, mainly applied between the peanut pier and the pier, when the situation is poor, it is to be planted After pouring enough water into the ditch, it can be ordered and fertilized. At the same time, planting sand in the ditch and applying 50% phoxim + 0.5% carbendazim 500 times solution to prevent diseases such as peanut stem rot and root rot. 3. Improve the quality of sowing Rigging: advocate ridge planting, ridge distance 30-40 cm, ridge width 55-60 cm, ridge height 10-15 cm, double row planting, row spacing 25 cm, hole distance 15 cm, seeding depth 5 cm, seeding amount 8500 ~ 10000 points / acre, 2 seeds per hole. Seed treatment: It is required to select double-grain fruit, and cover the shell for 2 to 3 days before shelling, and screen the first-grade rice for seeding after shelling, and advocate seed dressing with rare earth or seed coating, per kilogram of seed 2 grams of borax + 2 grams of rare earth can significantly improve yield and quality. Film mulching: Immediately after sowing in early April, 50% acetochlor is sprayed on the soil for weeding. The dosage is 100 ml/mu. It is required to be uniform and comprehensive. Then it is covered with black mulch and the ridge surface is flat and the membrane is tight. Both sides of the membrane are compacted with ridge soil. 4. Strengthen field management Broken membrane seedlings: When the peanut seedlings expose 2 to 3 true leaves, timely puncturing and rupturing the membrane to raise the cotyledons above the membrane surface, requiring 2 to 3 batches, in the morning or evening, no implementation at noon, then sealing Cover the membrane pores to keep warm and moisturize and prevent burning of seedlings. Check seedlings and seedlings: sowing 10 to 15 days after the emergence of peanuts, check the seedlings in time, find the lack of seedlings, timely soaking seeds and replanting, to protect the seedlings and seedlings. Appropriate cultivating, cultivating soil: Before germination and closure, properly cultivating loose soil, smashing the soil between the rows to the root of the plant, the thickness of 20 cm, so that the fruit needle is easy to enter the soil, combined with the soil, can be properly fertilized. Prolonged control: The main stem of the main stem is removed during the initial flowering period of the peanut, the control is prosperous, and the concentration of nutrients is promoted, which is beneficial to increase the result rate and single fruit weight. At the same time, for the elders of the saplings, 15% paclobutrazol can be sprayed 500 times. Strengthen the application of foliar fertilizer: the fertilizer needs to be large in the middle and late stages of peanuts. It should be applied from the flowering stage to strengthen the application of foliar fertilizer. Generally, it is sprayed once every 7 to 10 days, even sprayed 3 to 5 times. Commonly used foliar fertilizers are: 2% calcium perphosphate leaching solution, 0.3% potassium dihydrogen phosphate, 0.1-0.2% ammonium molybdate, 1-2% urea, especially 30 to 40 days before harvest, 1% urea + 0.3% dihydrogen phosphate Potassium helps prevent premature aging, promotes nutrient accumulation, increases yield, and improves pod quality. Strengthening water management: In the pod stage and pod ripening period, it encounters severe drought. It can be watered by planting ditch and water, avoid flooding and flooding, and should be shallow in time to prevent soil compaction in the ditch. In case of encounters, it is necessary to dig trenches in time. 5. Timely prevention and control of pests and diseases Black peanuts have strong resistance and less pests and diseases. Pay attention to strengthen the prevention and control of diseases such as rust and leaf spot, which can be used in the early stage of the disease with 20% powder rust 1500-2000 times, 70% methyl thiophanate 1200 times, 65% dysen. 600 times of manganese zinc and 120,200 to 300 times of agricultural resistance are controlled, with an interval of 10 to 15 days. 6. Appropriate harvesting Black peanuts have large water content during the maturity stage of the pods, slow dehydration, and short maturity period, which should be harvested at appropriate time to prevent sprouting and rotten fruit. When the leaves of the upper branches of the peanuts turn yellow, the network of the shells is clear, and the kernels are black and shiny, they should be harvested in time. The harvest is too early, the pods are not full, resulting in reduced yield, and the harvest is too late, and the pods are easy to fall off. The growth period is around 125 days. In summary, black peanuts are now a promising black food with broad prospects in health foods and medical foods. Interested considerations can be considered.
