Cultivation techniques of winter cabbage

Overwintering cabbage as a hot vegetable, many people have begun to grow, but not everyone can grow well, need to master certain techniques, so what is the cultivation technology of winter cabbage?

First, sowing time

The seeds are generally sown from July to August in the Yangtze River basin and south of the Yangtze River, and in July in the north of the Yangtze River and the Yellow River basin.

Among them, the frost-free period in the Yangtze River basin and its southern area is long, the winter temperature is slightly higher, the sowing period is from the end of July to August 20, and the latest cannot exceed August 20; the frost-free period in the north of the Yangtze River is slightly shorter, and the temperature gets lower as it goes north. Sowing time should be advanced appropriately. In the areas north of the Yangtze River, Henan and Shandong in the south of North China, the sowing time should be from the first ten days of July to the end of July.

II. Site selection

The dry, cool and ventilated planting land should be selected, and the high border should be used in the seedling raising land. The seedling should be divided into two leaves and the distance between the seedlings and 10cm is square.

III. Other field management

Prepare sunshade and rain-proof equipment for reasonable watering and fertilization.

Winter cabbage is generally planted at the age of 30 Mel for 35 days. Due to the gradual decrease of temperature in autumn, the earlier it is planted, the easier it is to manage.

Fertilization: select the plot in the previous crop of cruciferous crops in the planting land, fully apply high-quality organic fertilizer 5000kg/ mu and general compound fertilizer 50kg, deep ploughing fine rake, fully sun.

The overwintering cabbage was fertilized according to the soil fertility before winter. If the fertilizer is insufficient, it can be irrigated with a small amount of urea 10kg/ mu and small water after the temperature rises; if the fertility is good, only water but not fertilizer will be applied, and the management principle should be mainly controlled.

Watering: watering and fertilization are usually carried out in the afternoon or evening after planting.

After the winter cabbage grows, it can be put on the market in February-March of the following year.
