For the planting method of Chinese cabbage in the four seasons, the direct seeding method is used when the temperature is higher, on the contrary, it is replanted after sowing.

Selecting land for border: select the sandy soil field with no pollution, sunny direction and good drainage performance, adopt the way of narrow border and deep trench, and make the bed with a width of 1.2-1.5m. Select varieties: select suitable varieties, grow late-maturing varieties before late March, and early and middle-maturing varieties after late March. Fertilization: apply sufficient base fertilizer before planting, apply dilute manure fertilizer for 1-2 times on sunny days after emergence, and stop fertilization one week before harvest. Pest control: check frequently, remove weeds in time, and do a good job in pest control.

Planting methods of Chinese Cabbage in four Seasons

1. Select land for border

The fields with no pollution, excessive residue of heavy metals, sunny drying and convenient drainage are selected. The soil with good drainage performance, loose and fertile sandy soil, adopts the way of narrow border and deep trench, the border width is controlled at about 1.2-1.5m, and the border surface should be smooth.

2. Variety selection

The planting time is different, the varieties are also different, if planted before late March, it is best to choose late-maturing varieties; after late March, early and medium-maturing varieties are selected.

3. Fertilization

The cultivation of Chinese cabbage in high border has more overcast and rainy weather in spring, which will affect the growth of Chinese cabbage. In planting pakchoi, mature organic fertilizer was mainly applied, and rotten manure was applied as base fertilizer at the ratio of 4000 kg / mu. After emergence, dilute manure was applied 1-2 times in sunny day, and manure was stopped 7 days before harvest.

4. Disease and pest control

In the process of planting, it is necessary to remove weeds in the field in time, use silver-gray sunshade net to drive aphids, trap and kill with insecticidal lights, and check frequently to do a good job in pest control.

Breeding methods of Chinese Cabbage in four Seasons

Planting Chinese cabbage in four seasons is suitable for direct seeding when the temperature is high, and sowing and then transplanting when the temperature is low.

1. Wet the basin soil, spread the seeds and fine soil evenly on the soil surface, cover it with a thin layer of soil, spray the topsoil to keep it moist, generally sprout in 3-4 days, and it will take about 7 days if the temperature is low.

2. Keep the soil moist at the seedling stage, water once in the morning and evening every day when the temperature is high, and spray a thin mature organic fertilizer during watering 2 weeks after germination.

3. When the seedlings have 4-5 true leaves, they can be transplanted and planted, and the plant distance can be adjusted according to the size of pakchoi varieties, usually about 15-20cm. After planting, enough water should be irrigated, good shading work, and normal management can be carried out after the seedlings adapt to the environment and survive.

4. If transplanting is not needed, the seedlings should be carried out in time, and the larger seedlings should be pulled out so that the seedlings can be evenly distributed. The seedlings can be carried out many times, knowing that the spacing is appropriate, and Xiaobai should be given a mature organic fertilizer after each seedling.
