As leguminous crops, peanuts can fix part of nitrogen through rhizobium, but have high demand for elements such as phosphorus and potassium, and the fertilizer requirement is different at different growth stages (seedling stage, flowering stage and pod setting stage). Fertilization is to supplement the lack of soil nutrients and meet the nutritional needs of peanuts from seedling growth to pod development. Fertilization at the seedling stage promotes root and stem growth, fertilization at the flowering stage guarantees flower organ development, and fertilization at the pod setting stage helps fruit enlargement. Reasonable fertilization can avoid problems such as weak plants, less fruiting and unripe seeds caused by soil nutrient imbalance, can improve peanut yield and quality, and can prevent soil fertility degradation through scientific proportioning.
