Can Chinese cabbage be planted before and after cold dew?

1, Chinese cabbage can be planted before and after cold dew. Chinese cabbage can be divided into spring cabbage, summer cabbage and autumn cabbage. The suitable sowing date of spring Chinese cabbage is generally from the middle and late March to the middle and early April. Summer Chinese cabbage is usually planted in the middle and late May to the middle and early July. Under normal circumstances, it is best to plant autumn cabbage about 3 ~ 5 days before and after the cold dew, or postpone or advance it according to the specific weather conditions. If it is Chinese cabbage or water cabbage, it can be planted in accordance with the solar terms at any time and place, and can be picked within 1 month. Chinese cabbage can be planted all year round. Chinese cabbage in spring and summer also has Chinese cabbage in autumn and winter.

But in other cases, the taste of Chinese cabbage is not good. Generally speaking, it tastes like "Sao Chou" and doesn't taste like Chinese cabbage. Only the Chinese cabbage grown in beginning of autumn was obtained during the light snow solar term, which confirmed that first frost was hit by autumn cold, and the kiln that could not be eaten in winter was hidden in the basement, so this kind of Chinese cabbage was the best, and it was delicious when fried. If Chinese cabbage is taken as an example, the best sowing date should be about one week before and after cold dew. Because there will be a process of wrapping Chinese cabbage.

3. The optimum temperature of the core is 12-22℃. At this suitable temperature, cabbage leaves can grow and develop rapidly. In addition, if cabbage is wrapped in a winding core at a relatively high ambient temperature, leaves may curl due to the high temperature and high humidity of the internal structure of the wrapped winding core. Therefore, when cabbage is planted, it is usually in the cold dew and the ambient temperature is gradually decreasing. Chinese cabbage is a cruciferous vegetable, which likes wet and cold, and it is warmer in early autumn and after long summer.

4. It is suitable for the germination and seedling growth of Chinese cabbage after planting, and will not last long, so as to prevent various diseases and insect pests of Chinese cabbage at seedling stage. Cabbage is an easy bolting vegetable. If it is subjected to continuous ultra-low temperature in spring seedling stage, it is easy to produce immature bolting and endanger the yield of Chinese cabbage. Most kinds of Chinese cabbage should be wrapped in mustard balls, which requires some ultra-low temperature stimulation. How to make the core compact is beneficial to improve the yield, storage and taste.
