7. Planting key points
1. Select Heiye and Huaizhi as grafting rootstocks, and graft in spring or autumn;
2. For hilly and sloping land, carry out deep plowing and soil improvement before planting, dig deep pits for planting, apply organic fertilizer in layers, and transplant after the seedlings have 2 rounds of shoots, with a spacing of 5 m × 6 m and about 20 plants per mu;
3. Complete pruning of fruiting trees within one month after harvest, and promote 1 round of shoots in early-to-mid August and 1 round in late September;
4. After the last autumn shoots mature, carry out ring cutting or spiral girdling on large branches to control shoots and promote flowering. Fertilize reasonably during the fruit development period, mainly with decomposed organic fertilizer, and thin the fruit after the second physiological fruit drop, leaving 10 small fruits per panicle;
5. During shoot growth and fruit development periods, pay attention to the prevention and control of diseases and pests such as downy blight and stem borers.
