How do you raise seedlings for Chinese cabbage?

1. Cold-frame seedling raising

For seedling raising, a cold frame can generally be used, sowing one month in advance. When the low temperature at 5 cm inside the cold frame is stable above 10 degrees Celsius, you can water thoroughly, and after the water has completely penetrated into the soil, you can broadcast the seeds. After broadcasting, cover with about 0.5 cm of fine soil. The fine soil must avoid stones, as well as sand and other impurities.

2. Direct seeding for seedling raising

Chinese cabbage seeds can generally also be direct seeded. For direct seeding, water is usually applied within 7 to 10 days before sowing. Before sowing, you must open a shallow furrow of about 2 to 3 cm, keep the distance between each row at about 50 cm, then sow in rows, and after sowing cover with plastic film.

3. Temperature management

Whether direct seeding or seedling raising, you should pay attention to keeping the temperature between 10 degrees Celsius and 25 degrees Celsius. A day-night temperature difference of at least about 10 degrees Celsius is best. If it is lower than 10 degrees Celsius, premature bolting is likely to occur. If the temperature is higher than 25 degrees Celsius during the day, be sure to ventilate to cool it down.

4. Light management

In terms of sunlight, napa cabbage is a light-loving vegetable. During the seedling stage, its requirements for light are not too strict, but a certain light intensity must still be ensured to prevent the seedlings from growing wildly and becoming thin.

5. Fertilization management

In terms of fertilization, the seedling growth amount is relatively small, and the demand for nutrients is also relatively small. When the base fertilizer in the seedbed is sufficient, generally no additional topdressing is needed. When the seedlings grow to 4 to 5 leaves, they can be planted out.

The above is an introduction to Chinese cabbage varieties and seedling raising methods. To grow Chinese cabbage well, everyone must be careful. Only by learning all these basics and applying them can you grow high-yielding Chinese cabbage.
