I. Propagation methods: seed, cutting and striping propagation

(1) seed propagation: the fruit ripens in autumn, is dried and stored after harvest, sows and raises seedlings in March in spring, prepares the beds according to the general seedling land, spreads the seeds evenly in the ditch according to the row spacing of 6-7 inches, opens shallow ditches, spreads the seeds evenly in the ditch, covers soil for 2-3 minutes, covers grass and water, and emerges in about half a month. When the seedling height is 4-5 inches, it can be planted, and the plant row spacing is 0.8-1 foot × 1.2-1.5 feet.

(2) Cuttage propagation: the sturdy and robust branches were cut from June to August, which were 3-5 inches long and inserted obliquely in the seedbed. The temperature was 24-28 ℃, the soil was moist, it took about 15 days to take root, and it could be planted in about a week. The planting specifications are the same as above.

(3) striping propagation: when the plant is growing vigorously from June to August, the branches of strong and old plants are selected and corrugated, which is buried in about an inch of soil, pressed slightly, and can take root in more than 10 days, and be planted in the same year or the following spring.
