Cultivation points ① Garden construction: Choose loose, fertile, well-drained, sunny sloping land or flat dam land to be converted into civil gardens. Ridge cultivation with the density of 3m-6m× 5m-6m; (2) plastic pruning: no pruning within 4 years, light pruning or no pruning after 5 years, gradually cultivating the trunk and 3-4 three-dimensional main branches and auxiliary main branches to form a natural round-headed or tower-shaped crown structure; (3) Fertilizer and water management: the trees in the full fruit period should be mainly organic fertilizer, and potassium fertilizer should be added to supplement trace element fertilizer in a targeted manner. Fertilize 3 ~ 4 times a year, that is, accelerating germination fertilizer, stabilizing fruit fertilizer, strengthening fruit fertilizer and picking fruit fertilizer; ④ Pest control: mainly control red and yellow spiders, and at the same time control aphids, scale insects, black spot and anthracnose.
