Planting in autumn is generally from late August to early September and spring planting is from February to March. Plant spacing 2*3 or 3*4 meters. The width of each planting hole is 1 meter, mixed soil 2-3 tons of mixed fertilizer, 25 to 50 kilograms of mature pig manure or 2-5 kilograms of oil cake, 2 kilograms of superphosphate, 1 month after planting seedlings. When planting, the rootstock should be 5-10cm above the ground, drench the rooted water, and then water at any time to ensure survival. After 1 month of seedling survival, Fang Keqin applied thin manure to remove manure and added a small amount of urea.
Second, the soil, fertilizer, and water management shall be cultivated and weeded in due course.
Saplings are applied 1-2 times a month to remove manure water and appropriate amount of urea.

Saplings applied 0.3-0.5 kg of urea per plant, 0.5 kg of phosphorus and potassium fertilizers, and 30-50 kg of livestock and manure;
Young planting trees each applied 0.8-1 kg of urea, 1.2-1.5 kg of phosphorus and potassium fertilizers, and 50 kg of livestock and manure.
In adult fruit trees, organic fertilizers are mainly used to increase potash fertilizer. Each year, a total of 2-3 kilograms of oil cake, 2-3 kilograms of phosphorus and potassium fertilizer, 20 kilograms of green manure, and 70-100 kilograms of human and animal manure are applied per plant. Base fertilizer accounts for 50% of annual fertilization, 20% of spring fertilization, and 30% of summer fertilization. If appropriate, add root fertilizer (foliar spray).
