Four-season Chinese cabbage planting method (four-season fast-growing Chinese cabbage high-yield sowing and management technology)

When planting four-season cabbage, you should choose a pollution-free field with good drainage and air permeability. You can sprinkle some organic fertilizer water or apply some farmyard manure on the plants. Specifically, how to plant four-season cabbage with high yield?

1. Site selection

Soil is the foundation of planting. The selected soil should be pollution-free and not contaminated by heavy metals. It should face the sun, have good drainage, be fertile and loose, and have good air permeability.

The nutrient soil should be loose, breathable, and retain water and fertilizer. Generally, it is mixed with garden soil, leaf mold and organic fertilizer in a certain proportion.

2. Varieties

When choosing varieties for growing Chinese cabbage, it is best to choose varieties with strong disease resistance. If you choose to sow before late March, it is best to choose some late-maturing varieties.

If you choose to sow after late March, you can choose early and mid-maturing varieties. Choosing high-quality varieties can not only effectively ensure product quality, but also greatly increase yield.

3. Seed treatment

(1) Select healthy and disease-resistant varieties, and then use new lipid film to mix seeds, which can effectively repel underground pests and diseases, isolate virus infections, enhance seed respiration intensity, and improve seed germination rate.

(2) Choose the best time for sowing. Control the planting density during sowing and lightly rake the topsoil with a toothed harrow to allow the seeds to be sown deep into the soil.

4. Fertilizer

When planting Chinese cabbage, you should sprinkle organic fertilizer water on the plants. If you have farmyard manure mixed in the soil, you can apply some to the Chinese cabbage on a sunny day.

Chinese cabbage requires a large amount of fertilizer and likes water but is afraid of waterlogging. Therefore, when choosing a planting site, you should choose soil that retains water and fertilizer and has good drainage as the seedling bed.

Remove the residues of crops planted previously in the field in time, plow and dry the fields as early as possible, and do a good job of cleaning the fields. Apply sufficient base fertilizer, 1000-1500kg of decomposed chicken manure and 10-15kg of superphosphate per mu of land.

5. Pests

During the planting process, Chinese cabbage will also encounter a variety of diseases and pests, which have a great impact on the edible value and product value of Chinese cabbage. These diseases and pests will cause the leaves of Chinese cabbage to wither and rot, and in severe cases will lead to a complete failure of Chinese cabbage production.

Diseases include downy mildew, anthracnose, etc., and insect pests mainly include aphids, leaf miners, etc. Prevention and control measures include timely removal of weeds in the field, sprinkling some plant ash on the seedlings to prevent and control insect pests, or using insect killer lamps to lure and kill insects.
