First, peanuts in the middle of the growth of water and drought. When the peanut leaves are wilting, they must be timely watered; when there is a lot of rain, drainage should be drained in time. Especially in the later stage of peanut growth, the peanut field must not be filled with water, otherwise it will cause root decay, stem failure, rotting or sprouting. Autumn peanuts should be prevented from drought in the later period, and the soil must be kept cool to promote the healthy growth of roots and prevent premature aging of leaves. Increase fruit rate
Second, prevent peanut pests and diseases. Late to prevent peanut rust, leaf spot, aphids, and other pests and diseases. Leaf spot disease should be sprayed to prevent and control disease at the early stage of disease. Otherwise it will affect the maturation of fruit and reduce production, reduce production by 20% -30%, available 75% chlorothalonil 1000 times and 30% copper oxychloride, since the beginning of the flower according to the disease every 10 to 15 days to spray 1 drug, Spray 2 to 4 times continuously. High density of planting, poor ventilation and light transmission, and easy rusting. Begin spraying when the size of the needle tip is light yellow on the front or back of the blade. Spray 40% triadimefon multilatex suspension about 13 days apart. Once liquid, or 70% mancozeb wettable powder 400 times, spray 2 or 3 times continuously;
Third, control seedlings fall down, prevent leggy. Dwarf peanut plants, control the height of the plants between 30 and 40 cm, prevent lodging and lodging; and sprinkle about 50 kilograms of lime per acre between the flowering stage and the early stage to improve the fruit setting rate. Peanut full fruit period, the gradual decline of nutrition, mid-term leggy, temperature, rain, light and excessive application of nitrogen fertilizer and other factors cause fewer scars, especially serious in the late period. Therefore, for peanuts with an imperishable trend, attention should be paid to the time and amount of application of nitrogen fertilizers, and the timely control of pesticides has a significant effect on improving the yield of peanuts.
