two。 Between March and April of the following year, the seeds will be treated before sowing. Because the seed coat is hard, in order to make the seeds germinate neatly and unearthed quickly, soak the seeds with 0.5% potassium permanganate cold water solution for 2 hours before sowing, rinse the seeds with clean water and soak the seeds in hot water about 80 ℃ for 30 seconds (the longest can not exceed 1min, otherwise affect the germination rate), and sow seeds after 24 hours. Using this method to promote germination, the germination rate can reach 80% MUE 90%, and the growth after emergence is robust and not easy to get sick.

3. After the seedlings come out, the management work such as weeding, loosening, soil and topdressing should be strengthened. It was transplanted in spring or autumn in the second year, and the plant spacing was 3-5m.
