First, seedling cultivation æž‡æ· In the production and cultivation, grafting reproduction is the main, and 1 rootstock seedlings are cultivated. Choose the sandy soil that is sheltered from the wind, the texture is loose, and the fertility is medium and deep, and the fine roots are deepened, and the base fertilizer is used to form a ridge for use. 2 seedling grafting method.

Quality effect. Although it is more drought-tolerant, it is afraid of water accumulation, pay attention to irrigation and drainage.

V. Management of flower and fruit period In some years, the number of rainy days is long, and the formation of flower buds should be strengthened. Generally, it is necessary to ring the brush to promote Huawang 2 to suppress the tree growth. In the young fruit period to promote fruit growth and quality, it is necessary to increase the amount of nutrient transport in the whole garden. Prevent the occurrence of deformed fruit, cracked fruit and dead fruit.
Sixth, disease and pest control diseases are often leaf spot disease, anthracnose, leaf tip wilt, flax blight. Spraying targeted drugs + new high fat film for prevention and treatment.
