Cabbage has strong adaptability, both cold and heat resistance, and can be cultivated in the open field in spring, summer and autumn in northern China. Other relatively cold areas use more seedlings in spring and summer, summer sowing and autumn harvest, and some cities in North China, Northeast China and Northwest China mainly cultivate in spring and autumn.

2. A method for raising cabbage seedlings

Chinese cabbage is generally cultivated by seedling and transplanting, and spring Chinese cabbage is basically cultivated early. In cold areas such as Northeast China, greenhouse seedling raising is generally carried out in February and March, and the seedling raising period is between 60 and 90 days. Autumn Chinese cabbage seedlings are raised from June to July, and the seedling raising period is generally 35-40 days. Summer cabbage breeds from April to May, and the breeding period is about one month.

3, Chinese cabbage planting method

When the root system of Chinese cabbage starts to move above 5℃, and the average daily temperature reaches above 6℃, Chinese cabbage can begin to colonize.

4. Fertilizer and water management of cabbage

After planting Chinese cabbage, you need to water it slowly, but loosen the soil in time to raise the ground temperature and promote the recovery and growth of the root system. When cabbage enters the rosette stage, it will absorb more water and fertilizer, so it can be topdressing for the first time and supply enough water to promote the growth of leaf bulbs. After the bulbs are formed, you can control the watering.
