1. Planting time

Chinese cabbage is mainly planted in autumn. According to its different varieties, the sowing time can be divided into: early-maturing varieties are sown in early or mid-August, mid-late-maturing varieties are sown in Sow seeds from late August to early September, and late-maturing varieties are best sown in late August.

2. Base fertilizer for soil preparation

Cabbage can be grown in both north and south, so it does not have high soil requirements and can adapt to a variety of environments. However, it is rich in organic matter and loose and fertile. Sandy loam or loam is the best. The first crop of the plot chosen for planting should not be of the Brassicaceae family, and crops should be rotated reasonably. One week before sowing, the land should be prepared and fertilized. The land should be plowed deeply and finely raked, and then leveled and made into furrows. When making furrows, furrows should be opened to facilitate drainage and irrigation. Apply 5000-7000kg of decomposed organic fertilizer per acre, and also mix it with 50kg of nitrogen, phosphorus and potassium compound fertilizer. Spread it evenly on the soil and combine it with the cultivated land to mix the fertilizer and soil evenly.

3. Sowing and cultivating seedlings

Choose high-quality seeds with strong stress resistance, strong cold tolerance, and no disease. When sowing, you can use three methods: drill sowing, hole sowing and machine sowing. Choose the appropriate one. The sowing method is used for sowing, and the dosage per acre is generally about 0.5kg. When sowing, control the spacing between plants. If the climate, soil and other conditions are good, you can plant densely. Otherwise, plant sparsely. After the seeds germinate, keep the soil moist to speed up the emergence of the seedlings. When they grow to 2-3 or 4-5 true leaves, thin out and replenish the seedlings once each, and remove some weeds, diseased seedlings, and weak seedlings.

4. Planting

When the seedlings grow to have 5-6 true leaves, they can be transplanted. When transplanting, choose a sunny afternoon and try to avoid noon. Strong sunlight increases the survival rate. Also determine the density according to the variety and soil. Water immediately after transplanting to keep the soil moist. From now on, water once in the morning and evening for 3 consecutive days to slow down the seedlings and keep them alive.
