Appropriately increase planting density and adopt large and small ridge cultivation, which can seal the ridge early and stagnate early(propagation tray).

Except for the short frost-free period that is sown in July, all other regions are sown around Liqiu(nursery plant pots).

The stubble for planting Chinese cabbage varies from region to region, and weeds should be removed before planting and planting to reduce the number of intermediate hosts(gallon plant pot). For line-on-demand, 5 ~ 6 seedlings per hole should be left; the second time, when the seedlings have 3 ~ 4 true leaves 12 ~ 14 days after sowing, the sowing date should be determined according to the variety, land and climate factors(72 cell seed trays wholesale). It should be evenly withdrawn on demand.
Transplanted seedlings should be selected within 20 days of seedling age(cell trays). Large seedlings after 20 days are slow and difficult to move.
