What is the market demand for Chinese cabbage? What are the high-yield cultivation methods?

Chinese flowering cabbage, also known as cauliflower, is one of the characteristic vegetables deeply loved by consumers, mainly eating stems and tender leaves. Chinese cabbage is sweet and delicious, tender and nutritious, and is known as the "crown of vegetables". Chinese flowering cabbage has strong adaptability to the environment, fast growth and short growth period, and can be cultivated all year round.

Environmental requirements for Chinese flowering cabbage planting

1. temperature: Chinese flowering cabbage is not strict about temperature, and the average temperature is 10-28℃, so it can grow smoothly. At the same low temperature, early-maturing varieties of Chinese flowering cabbage are easy to pass vernalization, while late-maturing varieties need a long time to pass vernalization. In the actual planting, it is necessary to choose the appropriate varieties of Chinese flowering cabbage according to the local climatic conditions and planting season.

2. Illumination: Chinese flowering cabbage is a typical long-day plant. Adequate light is good for Chinese cabbage.

3. Moisture: Chinese flowering cabbage is neither drought-resistant nor waterlogging-tolerant, and the requirements for moisture are very strict. It is necessary to keep the soil moist and waterless.

4. Soil: Chinese flowering cabbage has low requirements for soil, and soil with general fertility can be planted. Nitrogen is the main nutritional requirement of plants, followed by potassium and phosphorus.

5. Land selection and soil preparation: In order to obtain high yield, it is necessary to choose loam with transparent ventilation, smoothness and looseness, convenient irrigation and drainage, and rich organic matter. Before formal planting, the field should be fully dried, and before sowing, deep ploughing, harrowing, ridging, drying and sufficient organic fertilizer should be applied. The whole plot is about 30cm high and1.2cm wide.

6. Reasonable close planting: When the first true leaf of Chinese flowering cabbage is unfolded, it should be sown in time, and then 1-2 times. When planting 3-5 real leaves, sow them in time. The specific planting density depends on the variety characteristics. Main planting density 12 cm × 15 cm, main planting density 15 cm ×20 cm. It is necessary to check the leakage and fill the gap in time and eliminate inferior seedlings.

7. Fertilization management: In addition to applying sufficient base fertilizer, topdressing must be done in time so as to apply thin and diligent fertilizer as soon as possible. After Chinese flowering cabbage emerges, topdressing is usually done once every 10- 15 days, and topdressing is 8- 10 kg of high-quality ternary compound fertilizer per mu. After fertilization, water it in time to avoid fertilizer damage.

8. Watering management: flowering plants in China have strict requirements on water, so we must correctly master the methods and times of watering. Spray water once in the morning and once in the evening on sunny days. After entering the hot weather, you can appropriately increase the number of watering. Be sure to control the water quantity before harvesting, so as not to affect the quality.

9. Timely harvesting: The best harvesting height of Chinese cabbage is 20-25cm. If the harvest is too early, the cabbage will be too tender and too small, and the yield will be very low. But if the harvest is too late, the yield will be high, but the quality will be seriously reduced.
