　　Yield performance: Four-year-old trees yield an average of 8.6 kg per plant. When grafted onto 15-year-old Nuomici trees, the yield reaches about 30 kg per plant by the fourth year after grafting.

　　Key cultivation techniques: (1) Use Huai Zhi as the rootstock for grafting, perform grafting in spring or autumn; (2) For hilly or sloped land, conduct deep plowing and soil improvement before planting. Dig planting pits 80 cm in depth, length, and width, and apply organic fertilizer in layers. Transplant when the seedling reaches 50 cm in height, with a planting spacing of 5×6 meters, approximately 22 plants per mu; (3) Perform shoot topping or pruning after each new shoot emerges. After the autumn shoots (fruiting mother branches) mature, control water and fertilizer. Perform girdling in mid to late December to control shoot growth and promote flowering; (4) Apply reasonable fertilization during fruit development to inhibit summer shoot growth; (5) During shoot growth and fruit development, pay attention to preventing diseases and pests such as downy blight and stem borer.
