After the autumn peanuts drop needles, the weather is dry and the temperature difference between day and night is large, which affects the development of the pods, so that the pods are not full. If the autumn peanuts are dropped after the needles are added, the leaves are supplemented with nutrients to improve the nutrition level of the autumn peanut plants. It can enhance the ability of autumn peanut plants to resist drought and adapt to large temperature difference between day and night, so that the pods develop well and the pods are full. At present, autumn peanuts have begun to drop needles, and foliar topdressing is at the time. The specific practices are as follows:
After the autumn peanuts are dropped, it is necessary to spray 0.1% borax, 0.1% magnesium sulfate, 0.1% zinc sulfate, 0.3% urea, 0.5% potassium dihydrogen phosphate, 1000 times triacontanol mixture every 7~10 days. Or 800 times Star Peng Phosphorus Potassium No. 1, 800 times Star Peng Calcium Magnesium No. 1, 1000 times amino acid compound micro-fertilizer mixture, or 25~30 times superphosphate and dry pure grass ash mixed leaching clear liquid, or 15~20 times The mixture of biogas slurry and 1000 times humic acid active liquid fertilizer is sprayed continuously for 3~5 times, and all the stems and leaves are evenly sprayed to start dripping with water drops.
