The peanut cultivation technology requires that base fertilizer is applied at one time, and extra-root top dressing is not generally carried out because the extra-root top dressing is very easy to break peanut pins at the upper part of the field and scratch peanut pods at the lower part. And phosphorus and potassium in the soil are easy to be fixed, and the absorption of the root system is directly influenced. According to the growth physiological characteristics of peanuts, the flowering period and the pod bearing period are sensitive to phosphorus and potassium requirements, and after the flowering period and the pod bearing period are lacked, flowering, fertilization, fruit needle formation and pod formation are directly influenced.
