Eliminate stagnant water After the autumn, if there is too much rain and poor drainage in the field, the roots of the peanuts will rot, the stems and leaves will decline, and the fruit rate will be reduced. In severe cases, the pods will rot or germinate. Therefore, when there is too much rain in the later stage, the ditch should be dredged in time to eliminate the accumulated water to ensure high quality and high yield of peanuts. Drought and watering The water requirement of the plants in the late growth stage of peanuts is reduced, and the moisture content of the soil is preferably 50% to 60% of the maximum water holding capacity in the field. Although the amount of water required in this period is small, in the case of dry weather, the roots are prone to decline, causing the top leaves to fall off, stems and branches to decline, and the rate of full fruit is reduced. Therefore, when the soil moisture content is lower than 40% of the maximum water holding capacity in the field, watering should be carried out immediately to protect the leaves and increase the fruit filling rate. When watering, use small water to quickly ditch or sprinkle irrigation, avoid flooding. Root dressing Although the nutrients needed in the late growth stage of peanuts are small, they have a great influence on the formation of yield and the improvement of pod fullness. The absorption capacity of peanut roots is weakened in the late stage. From the late stage of pod formation, 1% to 2% urea solution or 0.2% to 0.3% potassium dihydrogen phosphate solution should be sprayed once every 7 to 10 days, even spray 2~3 Second, each time 50 kg of spray fertilizer per acre to extend the functional period of 4 to 6 leaves in the upper part of the stem, and improve the fullness of the pod. Do a good job of three defenses to increase production Anti-Athlete: For the field with good water and fertilizer conditions and strong peanut growth, when a large number of peanuts are inserted into the soil, 15% of the paclobutrazol powder per acre is sprayed with 30-40 grams of water to 40-50 kg of water, or 20% of Zhuangfeng. 30 ml of water to 40 kg. It should be sprayed in the afternoon to avoid heavy spray and leakage spray. It should be re-sprayed after 8 hours of spraying. Anti-premature aging: For the application of insufficient or high-yield peanut fields, spraying foliar fertilizer in the late stage of peanut growth is an effective measure to obtain high quality and high yield of peanut. Spraying a mixture of 1% urea and 0.5% potassium dihydrogen phosphate 30 to 50 days before harvest, 50 kg per mu of spraying solution, spraying once every 10 days, generally spraying 2 to 3 times. Increase pod fullness. Prevention of pests and diseases: Because of the heavy rainfall and high humidity in the late growth stage of peanuts, it is necessary to do a good job in the prevention and control of leaf spot disease and cockroaches and cotton bollworms.
