What are the precautions for planting cabbage in summer?

Early-maturing varieties should be selected for planting Chinese cabbage in spring, and seedling protection should be done well. However, heat preservation measures should be strengthened at seedling stage to avoid long-term exposure to low temperature, and the base of green smoke occurs first. However, if the grafting is too early and the outside temperature is low, it is easy to smoke in the open air for a long time under the influence of low temperature at seedling stage, so we should pay attention to sowing spring-sown Chinese cabbage in advance. When planting Chinese cabbage in summer, it is in the high temperature and rainy season in summer because it is in the fruiting stage of Chinese parasol trees. When planting, heat-resistant and waterlogging-resistant varieties should be selected, because of their high summer temperature and rapid evaporation of water.

At the same time, the time to inhibit the growth of seedlings should not be too long, and it should be about 10 day. In spring, the growth of Chinese cabbage seedlings was inhibited for less than 5 ~ 10 days. It is also necessary to water vegetable tumors frequently, reduce the temperature, keep the soil moist, strengthen pest control and improve the quality of Chinese cabbage. Chinese cabbage is planted in autumn, usually in summer. In the autumn harvest season, the weather is hot and rainy. We should do well in the seedling stage and bear fruit under the buttonwood tree. The climate is mild and sunny, and it grows fast when it bears fruit. Chinese cabbage has less pests and diseases, high yield and good quality. After harvest, it can be stored in winter.

Planting Chinese cabbage in summer should be done after Tomb-Sweeping Day every year. Control the planting amount and cover the soil with plastic film after planting. When about 18% of the seedlings are unearthed, the plastic film should be removed immediately. Seedling raising and transplanting should be done well after emergence. Spacing began about half a month after emergence, and the interval was kept at about 1 1 cm. The soil should be kept dry and wet moderately. It is not advisable to irrigate a lot to avoid water accumulation in seedlings. The watering time should be controlled in the afternoon.
