After the seeds are ripe and collected in time, the seeds should be mixed with wet sand and put in the shade for stratification treatment. To keep the sand and soil regularly wetted, the seeds can be removed and sowed after about 6 months of sand storage; or soaked with concentrated sulfuric acid for 2 hours , And then rinse with water, and rub the carbonated seed coat, and then soaked in water for 1 to 2 yao, until the seed full absorption of low-humidity sand reservoir, after about 3 months of germination can be sown. Second, sowing. Sowing season, mainly in spring, usually in late March to early April. Shizujifei before sowing, irrigation at the end of foot water. The use of low bed broadcast, spacing 25 to 30 cm, 4 to 5 cm deep groove, soil cover 2 cm, after sowing repression, the seeds and soil in close contact. Third, seedling management. Seed germination unearthed, we must strengthen management and protection. When the seedlings up to 5 to 10 cm time seedlings, Dingmiao plant spacing of 10 to 12 cm. Leshan less pests and diseases, pay attention to soil weeding during growth, 6
