First, buy seeds
To the complete certificate, the legitimate seed store to buy the local main push peanut seed, the seeds should be full, uniform, uniform color, no mixed varieties of shelled peanut seeds, the seed quality meets the requirements of GB4407.2-1996.
Second, ready to sow
5 days before sowing, the purchased peanut seeds are shelled for 2 to 3 days to improve seed vigor and eliminate some pathogens. 2-3 days before sowing, peeling the shell and sorting the seeds, selecting first-grade peanuts for seeding, using 50% carbendazim wettable powder according to the seed amount of 0.3% to 0.5% or 12.5% ​​oxystonitrile nitrile according to the seed The amount of 0.1% seed dressing, water can be dried to control root rot and stem rot; control underground pests and rodents with 50% phoxim EC 75 ml and water 1 to 2 kg of seed dressing 40 to 50 kg, Make sure that the seedlings are strong and strong.
Third, the sowing date is determined
Irrigation is carried out during the grain filling period of wheat. When the wheat flag leaves begin to turn yellow or start sowing 15-20 days before the wheat harvest, the seeds are planted by artificial seeding or sowing, and the planting depth is about 5 cm, and the depth is consistent.
Fourth, reasonable density
20kg ~ 25kg per mu. According to the row spacing of wheat, the row spacing of peanut plants is adjusted. Generally, the row spacing is 30cm~40cm, the hole spacing is 15cm~20cm, the high-fertility plot is planted 10000~10500 points/mu, and the middle fertility plot is planted 10500~11000 points/mu. Planting low-fertility plots from 11,000 to 12,000 points/mu, 2 capsules per hole.
Five, top dressing technology
Topdressing in seedling stage: mainly applying organic fertilizer and biological fertilizer, combined with applying a small amount of urea. The medium-yield plot with a yield of 300kg/mu can be applied with 1000~2000kg/mu of high-quality organic fertilizer and 10kg/mu of urea; or 1000~2000kg/mu of organic fertilizer and 50kg/mu of biological compound fertilizer. The fertilization amount of high-yield land with a yield of 400kg/mu or more can be increased by 25%~30% on the basis of the above. Top dressing period: Foliar spray of bean fertilizer, green leaf treasure and other biological fertilizer or 0.2% potassium dihydrogen phosphate.
6. Prevention and control of pests and diseases
With “prevention first, comprehensive prevention and controlâ€, pesticides must have the “three certificates†of high efficiency, low toxicity and low residue pesticides prescribed by the state, and promote the use of biological pesticides. When the peanut plant is 35cm ~ 40cm, the acre is sprayed with 15% paclobutrazol wettable powder or 5% uniconazole wettable powder 50g ~ 100g with water 30kg, the control is prosperous.
Seven, harvest storage
When the peanut growth period is about 115 days, and the peanut fruit filling rate is over 70%, it will be harvested according to the weather changes. After harvesting, the pods are stored in a clean, dry, ventilated, pest-free and rodent area when the water content is less than 10%.
