Chinese kale is mainly produced in southern China, such as Guangdong, Guangxi, Fujian, Xiamen and Taiwan Province provinces. Planting in spring, especially in February and March, ripens in 6- 10 after planting.

Growth cycle of Chinese kale

1. Early maturity species type: Chinese kale can differentiate and form flower buds at high temperature, and it takes about two months from sowing to harvesting.

2. Medium-ripe type: The time from sowing to harvesting of Chinese kale is about two months, and the germination ability of lateral buds is moderate, and the harvesting period is basically two months.

3. Late-maturing seed type: Chinese kale takes nearly three months from sowing to harvesting, with strong cold tolerance, dense leaves, thick buds and high yield, and the harvesting period is as long as two months.

Key points of Chinese kale planting technology

1. Soil: Chinese kale has strong adaptability to soil, so sandy loam or loam with convenient irrigation and drainage should be generally selected, but it should be noted that such crops have not been planted in previous crops.

2. Planting: direct seeding or seedling transplanting can be used when sowing, and tender and strong seedlings with good growth, strong stems and large leaves should be selected when transplanting.

3. Illumination: Chinese kale needs sufficient illumination during the growth period, and insufficient illumination can easily lead to poor growth.

4. Watering: Mustard likes moist soil environment and is not drought-tolerant. The amount of watering should be controlled according to the temperature and humidity.

5. Topdressing: a small amount of nitrogen fertilizer should be topdressing after the seedlings grow slowly for 3-4 days, and the suitable quick-acting fertilizer should be topdressing after moss collection and topdressing for 2-3 times after moss collection.
