When is the planting time of Chinese cabbage?

Chinese cabbage can be divided into spring cabbage, summer cabbage and autumn cabbage. The suitable sowing date of spring cabbage is usually from late March to early April. Summer cabbage is usually sown from mid-May to early July. Under normal circumstances, it is best to plant autumn cabbage 3-5 days before and after beginning of autumn, or it can be postponed or planted in advance according to the actual weather conditions. If it is Chinese cabbage or water cabbage, it can be sown at any time according to the seasonal climate and harvested within 1 month.

Chinese cabbage cannot be continuously cropped, nor can it be rotated with other cruciferous vegetables. Sowing method: dig a ditch with a depth of 5 ~ 10 cm, and water along the ditch first. After water infiltration, the seeds can be evenly scattered in the ditch and covered with fine soil with a thickness of 0.8 ~ 1 cm. The amount of seeds used per mu is about 0.5 kg. After the sprouts are unearthed, direct seeding Chinese cabbage should be watered frequently to keep the ground moist and reduce the surface temperature. When it doesn't rain, generally water 1 time on the day of sowing or the next day to soak the ridge surface, and water it for the second time on the third day of sowing to promote the emergence of most buds.

The seedling age is generally 15 ~ 20 days, and when the seedling has 5 ~ 6 true leaves, it is the best time for transplanting. Transplanting is best done in the afternoon. Determine the appropriate density according to the variety. Water immediately after planting. After that, water was poured once every morning and evening for 3 ~ 4 days to help slow down the seedlings and keep them alive.
