(2) Transplanting: Both spring and autumn can be carried out. The autumn is planted in the leaves, and the spring planting is carried out before the germination. The transplanting density is between 150,000 and 180,000 plants per hectare. 3. Field management: (1) Seedlings: After the seeds are germinated and emerged, when the seedling height is 5 to 10 cm, the seedlings and the seedlings are planted, and 2 to 3 strains of the seedlings are left in each acupoint. Found that the lack of seedlings, with the seedlings under the planting, to achieve seedlings and seedlings. (2) cultivating and weeding: timely cultivating and weeding and cultivating the soil during the seedling period, keeping the field free of weeds, and the soil is loose and moist.
