Golden Baby Vegetable Basket: Spring Peanut Growing Technology

Peanut growth conditions are that if the 5 cm soil temperature is â‰¥12 Â°C, the seeds can germinate. For early maturing varieties such as â€œYueyou No. 116â€, its total growth period is 90 to 110 days, and the accumulated temperature should be â‰¥0Â°C around 2 450Â°C. For medium-maturing varieties such as â€œgranulationâ€, the whole growth period is 120 to 140 days. â‰¥0 Â°C accumulated temperature of 2 900 Â°C or so; Late-maturing varieties such as "Qinyou 71", the whole growth period> 150 d, need to â‰¥ 0 Â°C accumulated temperature of 3 250 Â°C or so. To achieve high production, we can take the following measures and methods.
1, apply base fertilizer. 300-400 kilograms of peanuts per acre, base fertilizer is generally controlled by 10 man-fertile organic fertilizers. Organic manure can be used to mix straw, sawdust, bark, rapeseed cake, distiller's grains, sludge, etc. The material is mixed and fermented and fermented. The fertilizer fermented by the organic fertilizer Fertilizer is fully decomposed, fast, and the organic matter is fully converted. In addition, 20-30 kg of ammonium bicarbonate, 50 kg of superphosphate, potassium chloride or potassium sulfate are used per acre. About 15 kilograms, 3 million kilograms of microbial fertilizer, can improve the soil, improve weight, improve the utilization of chemical fertilizers, improve soil consolidation and soil salinization, prevent soil diseases, uniform spreading before soil preparation, into the tillage layer.
2. Level land. The quality of the soil preparation is higher than that of the ground peanut field. It is required to be flat and free of debris that may puncture the mulching film, such as weeds and coarse soil. Press the width of the film to open the car, usually 80 cm ridge, ridge height 25 cm, ridge width 150 cm, sowing 2 rows of peanuts, spacing 25-30 cm, 80 cm wide plastic film cover, can also be 200 cm open car , The width of the car is 180cm, sowing 6-7 lines of peanuts. Careful attention should be paid to the construction of the drainage ditch when the site is opened, and the car cannot be filled with water.
3, selected fine varieties. Should choose early and mid-maturity, large fruit type, high yield potential, high quality Zhonghua No. 5 and other varieties; use of food or processed foods mainly for the selection of early-maturing, medium-fruit type, good taste quality Zhonghua 7 and other varieties; Hilly sand land; continuous cropping of peanuts, and bacterial wilt disease areas, Zhonghua No. 6 and other disease-resistant varieties should be selected. Before sowing, the germinated, discolored, and rotten seeds were removed, and ammonium molybdate was used for dressing. 2 grams of ammonium molybdate was mixed with 1 kg of peanut seeds.
4, timely sowing and reasonable close planting. The sowing time of spring sowing film mulching peanuts is about 10-15 days ahead of the local open field sowing. Soil moisture must be sufficient when sowing. Sowing depth 3-4 cm is appropriate. Density should be determined based on soil fertility and variety. Generally, the land with good fertility should be medium-mature and large-grain peanuts with about 8000 holes per acre, and about 8000-12,000 acorns with medium-early maturity. The basic control in 15 Ã— 27 cm is appropriate (ridge cultivation). Cover the soil after sowing, so that the car is smooth and easy to cover.
5. Spray herbicides. After planting cover soil, use 72% Dole emulsion per acre or 150% of a 48% pull rope emulsion, and dilute 50 kg of water, spray and spray the car.
6, cover micro-film. Cover the membrane immediately after spraying the herbicide. Membrane edges should be compacted with fine soil to achieve a flat film and tightness to prevent the wind from blowing through the film. Where there is a rupture in the mulch, it must be sealed with fine soil.
7, breaking the membrane seedlings. 10-15 days after sowing peanuts will emerge in succession, in the cotyledons unearthed and open, or cotyledons unearthed but can see the true leaves, with a finger or a blade to the seedlings will be a small cross-shaped mulch film, seedling film, and then Seal the membrane port with fine soil at the opening. Opening the seedlings should not be too late, especially to prevent high-temperature burning of seedlings in the film when sunlight is strong.
8, Qing Ke seedlings. Peanuts need to be cleared when the seedlings are established. The clearing trees have three functions: removing the weeds around the sowing hole; handing out the branches without growing out of the film; The seedlings are replanted in a timely manner to ensure full seedlings, and the membrane openings can be resealed during the clearing.
9, control leggy. The high-yield peanut-mulched fields, due to the better conditions of water and fertilizer, have a rapid growth and development in the early stage and a vigorous growth in the middle stage. Peanuts usually sown at the end of March or early April, during the period June 5-25, if the average pitch of the 8th to 12th section of the first pair of lateral branches reaches 10 cm and the plant height and the lateral branch length exceed 40 cm, the application 50 Kaclozole was sprayed with 50 kg of water, but spraying on the fruit was avoided. Crops with severe tendencies tend to spray again every 7-10 days.
10. Prevent disease and protect leaves in the middle and late stages of growth. According to the occurrence of local diseases, it can be sprayed with Bordeaux fluid and carbendazim for 3-5 times every 10-15 days in the flowering period to control leaf diseases (leaf spot and rust). The field with premature aging can be sprayed with 0.2% potassium dihydrogen phosphate for 1-2 times to prolong the leaf functional period. Pay attention to timely harvest, clear the field residual film. For details, please contact Beijing Huaxia Kangyuan Technology Co., Ltd.
