Choose sunny hillsides, valleys, hills, plains, roadsides and ditches with dry land, plough and apply base fertilizer, and form ridges or ridges according to the land.

2. Breeding method

1 Soak the autumn harvest seeds of sexual reproduction before winter, mix them with wet sand according to 1: 3, put them in a 0.7m deep pit, and cover them with 10 ~ 14? Thick and clean sand, compacted and covered with grass. Sow in spring or autumn in late June after thawing. 10. Seeds can be separated by 33? 7 ~ 10? As needed, or sowing, covering soil, watering and moisturizing. 30 two-year-old seedlings? Deep pit, soil compaction, root watering.

Asexual reproduction will chop off the roots of old plants and plant them again, in the same time and method as planting.

3. Field management before winter, loosening soil and weeding for 2-3 times, and the seedling height is 6- 10? When applying 225kg ammonium sulfate per hectare, the seedling height is 30? When topdressing calcium superphosphate per hectare 180 ~ 225 kg. Plastic pruning can improve the light and air permeability of the crown and increase the fruit setting rate. Off the ground 10 in full bloom? High trunk ring cutting 0.5? Wide skin can increase fruit setting rate 1 times. Healing began 20 days after girdling, and the healing rate was over 70% 1 month.
