From the perspective of fertilization types, N, P, and K mixed application has the best yield increase effect; followed by single application of P, and then N and P mixed application. Higher levels of N can extend the flowering period, while higher levels of P and K shorten the flowering period. Applying N600 grams, P200 grams, and K200 grams per plant per year can significantly increase the nut tree per plant and increase the total yield and kernel yield.

1. Adult trees over ten years old apply 250 grams of nitrogen per plant, 150 grams of phosphorus pentoxide and 150 grams of potassium oxide (that is, apply 2 kilograms of nitrogen, phosphorus and potassium fertilizer per plant, the ratio is 3: 2: 2) , Apply another 50 kg of compost or green manure.

2. In the first year of young trees, three months after planting, apply 250 grams of ammonium sulfate and 250 grams of superphosphate.
