Spring is an excellent planting season for Chinese cabbage. In this season, the temperature and humidity are suitable, the sunshine is sufficient, the climate is relatively stable, and there is no strong wind to cool down. Generally, the sowing period of Chinese cabbage in spring is from late February to early April, and the harvest period is from mid-April to late May.
Summer is characterized by high temperature and humidity, long sunshine time and strong sunshine, so summer can be regarded as the main harvest season of Chinese cabbage. Generally, the sowing period of summer cabbage is from late April to early July, and the harvest period is from mid-July to early September.
Autumn is the secondary planting season of Chinese cabbage, and the temperature drops sharply in autumn, so it is not easy to grow high-quality Chinese cabbage. In winter, the average temperature is low, the light is weak, and the growth of Chinese cabbage is limited. Therefore, it is not advisable to plant Chinese cabbage at this time as far as possible, but if the ground temperature is high, certain measures can be taken.
Points for attention in planting Chinese cabbage:
1, Chinese cabbage has shallow roots and is suitable for growing in soil with strong water and fertilizer conservation ability. Planting Chinese cabbage requires flat soil and loose soil layer. Before planting, apply sufficient base fertilizer in the field, preferably manure and compost with long-lasting fertilizer effect, and apply high-quality organic fertilizer of more than 5000 kg per mu, combined with cultivated land. In addition to using organic fertilizer as base fertilizer, it can also be mixed with chemical fertilizer as base fertilizer. Generally, flat border or high border planting is used in northern areas, and high border planting is mostly used in southern areas.
2. Most Chinese cabbages are planted by direct sowing, generally by drilling. Chinese cabbages seeds are evenly spread on the border. After planting, water spraying should be insisted in the morning and evening until Chinese cabbages germinate. After Chinese cabbages grow two true leaves, the first thinning should be carried out, and the Chinese cabbages that grow too densely and grow weakly should be pulled out. After this thinning, the Chinese cabbages should be confirmed for the second time.
