After many years of production practice survey statistics, the main reasons for peanut rotting fruit are rotting fruit, arid and rotten fruit, rainy rotten fruit, rodent rotten fruit, mechanical rotting. For these reasons, taking effective preventive and control measures is the key to seizing the bumper harvest of peanuts. 1. Drug treatment Peanuts should be coated with special seed coating agent for peanuts when sowing, so the effect is better. Or when peanuts are planted before planting, use 5% of phorate or phoxim 38-45 kg per hectare and mix 225-300 kg of soil. When sowing, use 50% phoxim 500ml, add 40-50kg of water, and 400-500kg of seed dressing. Peanut crusting period, with 90% crystal dipterex 2000 times Irrigation root, the effect is also more ideal. 2. Ridge planting Before ridging, apply “filling Fertilizer†to cultivate strong seedlings. For calcium-depleted soil, attention should be paid to the application of calcium fertilizer. 3. Rational irrigation and drainage of soil water and excessive water are not conducive to high yield of peanuts. Generally, when the soil moisture content is less than 10%, it is necessary to water the soil in time, and the watering should be suitable for furrow irrigation, and the spray irrigation effect is better. Drainage is to achieve "five channels" in common, when the continuous rainy water flow, keep the field without water, enhance the stress resistance of plants and pods, reduce the rate of rotten fruit. 4. Control of rodent pests Use poison baits to trap and kill rodents. One kilogram of zinc phosphide can be used, and 20 kilograms of millet or wheat can be added. It can be placed at equal distances or ratholes in the field. 5. Timely harvest of the top growth point of the peanut plant stops growing, the upper leaves turn yellow, the middle and lower leaves turn from green to yellow and gradually fall off, the stems appear aging and turn yellow-green, most of the pod husks become hard and clear, sponges Shrinkage of tissue shrinkage and a dark brown luster, when the skin is full and thin, showing the inherent luster of the species, can be harvested. The harvest is mainly based on manual removal to reduce fruit loss and increase production and income.
