Published: 2024-11-08 Author: mysheen
Last Updated: 2024/11/08, Fertilization: after deep ploughing (autumn ploughing), fertilizing in autumn, applying farm manure 3~5m3 per mu, every other year on both sides of the shelf, close to the planting ditch wall in the first two years, opening a ditch with a depth of 60-80cm and a width of 40cm between rows after the third year, and covering the soil immediately after filling. Topdressing twice a year, the first time in the budding stage (early May), the second time in the middle of plant growth (early July) topdressing available phosphorus and potassium fertilizer. With the expansion of the tree, the amount of fertilizer increased year by year, ammonium nitrate 25-100g/, calcium superphosphate 200-40O

Fertilization: after deep ploughing (autumn ploughing), autumn fertilization is carried out, 3~5m3 of farm manure is applied per mu, and it is carried out on both sides of the frame every other year. In the first two years, it is close to the planting ditch wall. After the third year, a ditch with a depth of 60-80cm and a width of 40cm is opened between the rows, and soil is covered immediately after filling. Topdressing twice a year, the first time in the germination stage (early May), topdressing available nitrogen and potassium fertilizer, the second time in the middle stage of plant growth (early July) topdressing available phosphorus and potassium fertilizer. With the tree body expanding, the fertilizer dosage increases year by year, ammonium nitrate 25- 100g/plant, calcium superphosphate 200- 400g/plant, potassium sulfate 10 - 25g/plant.

Irrigation: depending on the conditions, it is best to irrigate frozen water once in late January, irrigation is best after fertilization, or irrigation after thawing in early May, irrigation of fruit water from late May to mid-June, and irrigation once again in June and July if the rain is insufficient.
