High-yielding Cultivation Techniques of Chinese Cabbage in Spring

Spring is the season for growing cabbage, so what are the high-yielding techniques for growing cabbage in spring? The following editor will introduce the high-yield cultivation techniques of Chinese cabbage in spring.

I. Variety selection

Suitable varieties should be selected for planting cabbage in spring, with bolting tolerance, cold tolerance, fast growth and good quality as the key points, such as Chunzhenbai 6, Gao Chunhuang, improved Jingchunlu, Jinbai 56, Jinxia 3, Xiaoza 56, Xiaoza 60 and so on.

Second, sowing seeds at the right time

The sowing time of different varieties is also different. Generally, spring cabbage is sown from March to April. If the soil moisture in early spring is not good, it can be watered 10 days earlier to make soil moisture. When sowing, each row is 2-3 rows, that is, the row distance is about 50cm, and the hole distance is about 40cm. Sow 5-6 seeds per hole, cover the soil after sowing, increase the soil temperature and improve the survival rate of cabbage seedlings.

3. Raising seedlings

In order to overcome the problem of short production season of Chinese cabbage in spring and early bolting through vernalization stage, it is necessary to use protective ground to keep warm and raise seedlings. The specific method can be that when the average daily temperature in the open field is more than 10 degrees, then transplant into the field. At the same time, strive for the heading of Chinese cabbage to be completed before the average daily temperature is 25 degrees, so that the growing Chinese cabbage is much bigger.

IV. Colonization

The growth process of Chinese cabbage in spring is basically in the plum rain season, and the cultivation time is short, so in order not to lose soil fertilizer, it is necessary to apply sufficient base fertilizer before planting, especially to apply phosphate fertilizer frequently, to prepare the soil with deep ditches and high borders, so as to facilitate drainage and irrigation and reduce soil stagnant water. under the condition of low temperature and rainy in early spring, plastic film mulching is one of the key techniques to grow Chinese cabbage in spring. Plastic film mulching can increase soil temperature, prevent soil fertilizer loss and reduce the occurrence of diseases and insect pests, cover high transparent plastic film, cover tightly with soil cover, and increase soil temperature.

5. Reasonable close planting

The seedlings will emerge 4-6 days after sowing, break the membrane to introduce the seedlings in time after emergence, make the cotyledons expose the plastic film, and compact the small holes of the plastic film with soil blocks to prevent the seedlings from burning. After the seedlings are broken, the seedlings will be planted once between 3-4 true leaves and 5-6 true leaves.

VI. Fertilizer and water management

Planting cabbage in spring should strengthen fertilizer and water management, timely ploughing, promote root development, base fertilizer can apply high-quality ternary compound fertilizer, rapeseed cake, holding boron, sprinkle urea on the border, and 20 kg urea and 20 kg potassium sulfate per mu during rosette period. watering should be carried out according to soil moisture, usually watering once every 5 days.

VII. Disease and pest control

The main disease of Chinese cabbage is downy mildew, spraying poison alum and carbendazim at seedling stage, spraying 1000 times dimethoate and 1000-1500 times phoxim to control aphids and cabbage green insects in the middle and later stage.

VIII. Harvest in time

Chinese cabbage should be harvested in time. Chinese cabbage can be harvested from mid-late May to early June, and can be picked and listed when the leaf ball is 80% hard.
