In order to sow evenly, mix the appropriate amount of fine sand or humus into the seeds and use seeding. Spring sowing: Sand storage should be carried out in advance, that is, the seeds are mixed with fine sand 1: 3 after harvesting, maintaining a certain humidity, buried outdoors, affected by low temperature in winter, and then taken out for seeding, with a pitch of 1-1.3 feet and a pitch of 0.7- 1 foot, covered with soil for 2-3 minutes. Sowing amount per acre is 3-4. The multiplication of the shoots occurs in early April in early spring, before the buds are unearthed. All the roots are dug out and divided into small clusters. Each cluster should have 1-2 small buds, and then planted at a row spacing of 1.3 feet and a plant spacing of 0.7-1 feet. Do not expose the buds to the soil to avoid being dried by the wind.
