The hole expansion and soil improvement is carried out every autumn, which can be applied to crop straw, livestock and poultry manure, biogas residue fertilizer, cake fertilizer and so on. The deep soil improvement of the whole garden should be completed within three years. The amount of basal fertilizer applied by expanding holes in each tree is not less than 75kg per year.

Strong fruit fertilizer and fruit picking fertilizer were applied in July and October.
