When transplanting, the seedlings are separated to prevent seedlings from bullying. Each row of 3 rows, spacing 43-45 cm, spacing 24-26 cm. Among them, Zhongmu No. 2 has a density of 4000-4200, and Huyujing No. 2 and Caicha No. 2 have a density of 4300-4500. After the first film was transplanted and planted in a directional manner.
