Early spring cabbage planting technology introduction!

Cabbage, also known as cauliflower, cabbage, lotus white (Yunnan), kohlrabi, is an important vegetable, which is planted everywhere. Let's learn about the planting techniques of cabbage in early spring.

Planting techniques of cabbage in early spring

1. Soil preparation and fertilization

In order to select fertile soil, fully mature farm manure should be applied to match the right amount of nitrogen, phosphorus and potassium ternary compound fertilizer. Thoroughly disinfect the seedbed before sowing. Generally, 5000 kg of rotten farm manure and 50 kg of compound fertilizer are applied per mu. In order to improve quality and stress resistance, high quality calcium fertilizer can be combined.

two。 Seed selection and seedling raising

Early and middle maturing cabbage varieties with strong winter and bolting tolerance should be selected for planting cabbage in early spring. Varieties with early maturity, high yield and strong disease resistance can be selected for open field planting in spring, such as Zhonggan 15, Jufeng Quanmei, Shuanghuan 15, Zhonggan 21 and so on. Cold-resistant, disease-resistant and winter varieties can be selected for cultivation in cold shed in early spring, such as Lubaowang, Shuanghuan 45, Xuan 8398, Chunqiang and so on. The seedlings should be raised by dry seed direct seeding, the seedling beds should be raked flat and poured with sufficient bottom water, and the seeds should be spread evenly. After sowing, cover the fine soil to preserve soil moisture, the fruit seedlings are too dense, need time seedlings, when the seedlings grow to about 2-3 true leaves, they should be divided into nutrition bowls.

3. Timely planting

The planting time is determined according to the cultivation model, in which the arch greenhouse can be planted in the first and middle of February, the plastic film in the small arch shed can be planted in the last ten days of February, and the plastic film mulching can be planted in the first and middle of March.

4. Field management

Fertilization: apply quick-acting nitrogen fertilizer with water flushing in time to promote early development. At the beginning of the package, the supply of compound fertilizer should be changed to Chong, 20-25kg per mu to promote the expansion of leaf bulbs.

Watering: control watering 7-10 days before harvest to prevent late ball cracking.

Pest control: cabbage diseases are few, mainly aphids and cabbage insects.

In addition, the harvest time of cabbage in cold shed in early spring is generally from the end of April to the beginning of May. Growers must harvest at the right time and go on the market in time after harvest.
