1. Collection and storage of seeds. The seeds of Hovenia dulcis, which is healthy, free of diseases and pests and about 20 years old, must be collected for sowing and propagation. The operation time is generally after the autumn fruit is mature. The basic methods are natural and artificial. The manual method is to use seed collection tools for operation, or directly pick up the seeds falling on the ground. After the seeds are collected, they should be dried for a period of time. When the outer shell of the seeds is completely cracked, they can take out the seeds, and then store the seeds in the clean sand with the relative humidity of 40% - 50%.
2. Seed treatment. Before sowing, the seeds of Hovenia dulcis should be treated with 20% edible alkali solution and clean sand, then washed with clear water and soaked in clear water for standby.
3. sowing. The seedbed should select the sandy soil with good fertility, and remember to apply fertilizer after sowing seeds. Sowing adopts the way of ridge sowing, with a row spacing of 50cm and an interval of 5cm to 7cm to sow three or four seeds. After sowing, the seeds should be covered with fine soil of 3cm to 4cm.
4. Management after sowing. Before the seeds of Hovenia dulcis can germinate, they must be kept moist continuously. They must be protected from the sun and the sun.

The branches with mature leaves and robust buds, 15-20cm long, are cut, the lower cut of the branches is cut into a slope, and the cut is slick for standby. First of all, we need to use tools to Jack in the cultivation ground. The spacing between holes is 5 to 8 cm. Then we need to insert the prepared branches to be cutted into the air. The depth is 4 to 6 cm. After compaction with soil, we need to water them once. After that, we need to water them once every 10 days, but we need to water them thoroughly, so that the survival rate of cuttings can reach more than 80%.
