How to prevent premature senility of peanuts?

How to prevent premature peanut aging? To prevent premature aging, please guide peanuts to do the following: 1) Selection of land. Select the field with higher fertility, apply sufficient base fertilizer, deeply plow 25~30 cm in advance, and dry the ridge. 2000kg of decomposed manure or 25 - 35kg of cake fertilizer, 50kg of ternary compound fertilizer, 50kg of phosphorus fertilizer, 1kg of zinc fertilizer and 250 - 500g of boron fertilizer are applied as base fertilizer per mu. 2, weeding, plastic film after the ground temperature rise, grass damage is often more serious than the open field, therefore, chemical weeding must be carried out after sowing. Mu can be used with 72% of 100 ml of duer, 50 kg of water while the soil is wet spraying. Cover immediately after spraying. 3. Topdressing. After mulching, the soil temperature rises, the fertilizer decomposition accelerates, the plant absorbs more in the early stage, and it is easy to remove fertilizer after pod setting, especially in the plot with poor soil fertility. Therefore, in the flowering period should be 20 kilograms of urea mu, water dressing. Foliar fertilizer can also be sprayed 2-3 times, and a mixture of urea and potassium dihydrogen phosphate can be selected, or sprayed with treasure, etc., after 4 p.m. 4. Watering. When soil moisture is insufficient, especially around noon in summer, plants will temporarily wilt and cause premature senescence. Should be watered in time in the evening, and in the row shallow loose soil to preserve moisture. 5. Prevention of disease. Leaf spot is the main disease of peanut. It is easy to occur due to heavy rain and humidity. 50% carbendazim WP 800-1000 times solution, 50% mancozeb 500 times solution, 70% thiophanate-methyl 1000 times solution or 75% chlorothalonil WP 600 times solution can be sprayed before and at the initial stage of disease. 7-10 1 time a day, continuous spray 3 times, pay attention to rotation of medication.
