If the seeds of Chinese cabbage are properly maintained after planting, it will take 20 to 25 days to germinate. br/>； It takes about three weeks for Chinese cabbage to germinate without accelerating germination, and the germination rate is very low. Therefore, it is usually necessary to accelerate germination before sowing. The method of accelerating germination is simple. The seeds are directly soaked in warm water of 30℃ to 40℃ for about 24 hours, and then taken out for sowing. After sowing for about a week, they will germinate with high germination rate. br/>； Sowing method: br/& gt；; 1. Sowing date: The best sowing date of Chinese cabbage is from April to July, when the climate and temperature are more suitable, and it can germinate quickly after sowing, which is also convenient for management. If it is planted in a greenhouse, it can be planted at any time, regardless of time, as long as the temperature can be controlled. br/>； 2, soil treatment: it is best to choose soft and fertile soil for planting Chinese cabbage, which can not only supplement nutrients, but also not easy to accumulate water, which is conducive to growth. If possible, the soil can be disinfected once to reduce pests and diseases. br/>； 3. Sowing method: The sowing method of Chinese cabbage is very simple. Sprinkle the germinated seeds directly on the soil surface, and then cover them with two centimeters of soil. If the soil is dry, you can often spray water to improve the humidity and promote the seedlings to grow faster. More fertilizer and water are consumed at seedling stage, and thinner fertilizer and water can be applied after emergence, so as to promote the seedlings to grow more vigorously and emerge more orderly.
