Disinfect the soil with formalin or carbendazim 3-4 days before sowing and fill with bottom water. After the water dries, 33cm according to the row spacing, pull the wire to open the ditch, spread the sand mixture sparsely, and the seed amount per 667m2 is 6~7kg. After planting, cover the soil with about 1.5~2cm, gently press, flatten, and then cover with plastic film. At the same time, drainage ditches are opened around the seedbed to facilitate drainage in autumn. Be careful not to water the seeds before they germinate.
