Peanut shell is a very common phenomenon, mainly due to the lack of calcium, boron, molybdenum, phosphorus and other necessary nutrients. Qiao fertilizer can reduce the occurrence of peanut shell phenomenon. 1, increase organic fertilizer due to the comprehensive nutrition of organic fertilizer, generally per acre applied maturity organic fertilizer 3000 to 4000 kg base fertilizer. The amount of basal fertilizer can be used for ploughing; it can be applied as a seed fertilizer with a small amount. 2, the application of calcium superphosphate because of superphosphate not only contains phosphorus, but also contains a lot of gypsum, also known as calcium sulfate, gypsum, for the soil to increase calcium fertilizer. Generally, 30 to 40 kg of calcium phosphate per acre is applied as base fertilizer. 3. The application of boron fertilizer boron is a necessary nutrient element for the normal development of plant organs and reproductive organs. Sandy soil and severe boron-deficient soil can apply 1 kg of borax per acre to make basal fertilizer or seed fertilizer. Ordinary soil can be used in the initial flowering period with 0.2% ~ 0.3% borax solution for extra-root dressing 2 ~ 3 times. 4, spraying molybdenum molybdenum fertilizer can promote the development of peanut nodules, dark green leaves, growing strong, fruit full and full. In the early flowering stage or the next stage of acupuncture, 0.3% to 0.5% ammonium molybdate solution is used for extra-root fertilizer. 5, deep application of potash potassium fertilizer to deep below the results layer to prevent the results layer containing too much potassium, affect the absorption of calcium, increase rotten fruit. Finally, if the peanut seedlings grow weak and the leaf color is light, 0.3% urea and 0.3% potassium dihydrogen phosphate solution can be added. Once every 7-10 days, continuous spraying 2 or 3 times can reduce the empty shell rate of peanuts and increase the firmness. The rate can generally increase production by more than 10%.
