Detailed Explanation of Key Management Techniques for Chinese Cabbage at the Seedling Stage

Seedling stage management of Chinese cabbage refers to the management from the emergence of young sprouts to the rosette stage. At this time, thinning should be done in a timely manner, and at 2-3 true leaves or 4-5 true leaves, thinning should be carried out once each, while removing weeds, diseased seedlings and weak seedlings. When there are 6 true leaves (rosette stage), the seedlings should be finalized, and timely intertillage should be carried out to avoid damaging roots and leaves. Intertillage should be shallow rather than deep. For direct seeding, planting is generally done at 5-6 true leaves.

Transplanting and planting. The seedling age is generally 15-20 days, and when the seedlings have 5-6 true leaves, this is the optimal period for transplanting. Transplanting is best done in the afternoon. The appropriate density should be determined according to the characteristics of the variety. Water immediately after planting. Thereafter, water once each morning and evening every day for 3-4 consecutive days to help the seedlings recover and survive.
