Chinese cabbage must have many people planting it, and it is also relatively good at planting techniques. However, if you want high-quality and high-yield products, you must master the technical points of fertilization of Chinese cabbage. Next, we will summarize the technical points of high-quality and high-yield cabbage. .

1. Pay attention to the application of potassium fertilizer. Potassium application can enhance the disease resistance and storage resistance of Chinese cabbage, but the application of potassium fertilizer is often neglected in production. Generally, the amount of potassium applied is 20 kg of potassium sulfate or 15 kg of potassium chloride. In the absence of potassium fertilizer, a part of the plant ash can be applied.

2. Apply enough organic fertilizer. Applying the base fertilizer is the basis for obtaining a good harvest of Chinese cabbage. Generally, the soil fertility of old vegetable fields is high, and the application of organic fertilizer should be appropriate; while the soil fertility of new vegetable fields is not high, it is particularly important to re-apply organic fertilizer and phosphate fertilizer as base fertilizer.

3, clever application of seedlings fertilizer. After the cotyledon of Chinese cabbage grows, the main root has reached about 10 cm; and the first-order lateral root has occurred, which has the ability to absorb water and absorb fertilizer. In the case of insufficient base fertilizer or no fertilizer application, a small amount of seedling fertilizer should be applied. 5-7 kg of urea to promote growth. When applying fertilizer, it is important to apply small seedlings and weak seedlings to promote the formation of strong seedlings.

4. Reasonable topdressing. Generally, it is necessary to grasp the seedlings of the seedlings and start to enter the rosette period and start the top dressing twice before the start of the core, which is the key to ensure the high yield of Chinese cabbage. At this time, Chinese cabbage is in a rapid growth period, and the amount of topdressing should be increased. Nitrogen is the main factor, nitrogen fertilizer is combined with phosphorus and potassium fertilizer, or water feces are applied regularly. During the growth period, the leaf surface sprayed with 1000 times diluted 891 plant growth factor (titanium citrate) or 0.5%-1% urea and potassium dihydrogen phosphate mixture can increase the vegetable yield of Chinese cabbage and improve Commodity value.
