Planting time of Chinese cabbage in the south

Chinese cabbage has strong adaptability and can grow well in the southern region whether planted in spring, summer or autumn.

The specific planting time should be determined according to actual weather conditions.

How to grow southern Chinese cabbage

1. Land preparation

Chinese cabbage does not have high requirements for soil and can grow normally in soil of various properties in all regions. However, in order to promote its vigorous growth and higher yield, it is best to prepare the land before planting and apply enough base fertilizer to the land to ensure that the nutrients in the soil are conducive to the later growth of Chinese cabbage.

2. Processing seeds

There are many varieties of cabbage. When planting, you should choose the appropriate variety according to the climate and soil conditions of the area. The cabbage seeds should be plump and disease-resistant. Soak the seeds in warm water for 15 minutes before sowing. After taking them out, mix the seeds with Benomyl to sterilize them. This can reduce the infection rate of pests and diseases.

3. Sowing method

The processed Chinese cabbage can be evenly spread on the soil surface, covered with a thin layer of soil, and sprayed with water to keep it moist. If the environment is suitable, seedlings will soon grow. Chinese cabbage consumes a lot of nutrients during the growing season, so it is necessary to apply fertilizer in time to ensure sufficient nutrition, and do a good job of weeding to avoid competing for nutrients.

Key points for planting Chinese cabbage in the south

1. Cabbage is very prone to disease if it is planted continuously on the same piece of land, and the soil will become barren and compacted. It is best to plant it in rotation with field crops. If the temperature is too high, the cabbage will stop growing, and its yield will also be affected to a certain extent. Therefore, it is best to control the growth temperature of cabbage below 30℃, and do a good job of shading and cooling in summer.

2. Chinese cabbage is prone to soft rot, which usually occurs during the heart stage. At this time, it is necessary to promptly remove rotten leaves and spray pesticides for timely treatment. In addition, sufficient water must be ensured. Spodoptera litura is a common insect pest that will gnaw on the leaves. In severe cases, it will eat up all the leaves. It should be treated in time and the insects should be eliminated as much as possible in the early stages of the infestation to avoid more serious problems in the later stages.
