Cultivation Techniques of Early-maturing and High-yield Cultivation of Spring Cabbage

One is to use good breeds. The use of strong winter, late bolting, cold-tolerant and high-yield varieties is the basis for the success or failure of spring cabbage cultivation.

The second is cold seedlings. The use of plastic film covering the small arch nursery, so that the cold insulation, ensure that the key to the growth of cabbage seedlings, to avoid the spring vernal cabbage through vernalization and early bolting, resulting in loss of production.

The third is to apply base fertilizer. Choose a well-drained sandy loam vegetable field, after the harvest of the former crop, turn it on the ground in time, and build a sorghum with a width of 1.7-2 meters and a ditch with a depth of about 30 centimeters so as to facilitate the drainage of 667 square meters. 1000 to 1500 kg of decomposed pig manure and 10 kg of compound fertilizer are used as base fertilizer.

The fourth is to strengthen management. The strong seedlings were transplanted in a timely manner, covered with a small plastic shed after planting, and the temperature in the greenhouse was about 20°C during the day to promote the rapid growth of the plants. Warm up the temperature and remove the shed after the weather is stable. Shallow cabbage roots, weak absorption capacity, strict requirements on fertilizers and water. During the whole growth period, many nitrogen fertilizers are applied to topdressing, and generally 15% to 40% of human waste is used as top dressing. Gradually increase the concentration as the plant grows, and top dressing is stopped 8-10 days before harvest. At the same time, field management such as cultivating and weeding and pest control should be done to promote early maturation and high yield.
