Chinese cabbage is a leafy vegetable with a large number of leaves and a heart-shaped leaf. It is the main harvesting organ. Generally, it can reach 4000-5000 kg per mu. Chinese cabbage has a long growth period. To get a high yield, you must master several key technologies:
1. Applying the base fertilizer: The base fertilizer is the basis for the harvest of Chinese cabbage. Generally, the soil fertility of old vegetable fields is high, and organic fertilizer can be applied in moderation. The nutrient ratio of compound fertilizer is mainly nitrogen and potassium, and combined with phosphate fertilizer. The new vegetable land should be re-applied with organic fertilizer and applied with ternary compound fertilizer.
2. Rose seedlings: In the seedling stage, water control nitrogen fertilizer should be controlled. In addition to the introduction of seedling fertilizer, it is generally necessary to seedling the seedlings during the rosette period, so that the outer leaves of the shoots grow robustly, promote the roots under the tie, and lay the foundation for the rapid growth and the absorption of nutrients and water in a large amount.
3. Topdressing: The first topdressing should be mastered in conjunction with irrigation during the late period of the rosette. The topdressing fertilizer is mainly based on the quick-acting nitrogen fertilizer, and the water-fertilizer enters the enveloping period. The 2-3th top dressing is carried out in the early and middle stages of the package. Mainly apply nitrogen fertilizer, up to two times, to control the dosage. After the core of the package, the nitrogen fertilizer was stopped. The amount of nitrogen fertilizer per top dressing should be determined by the growth of Chinese cabbage.
Foliar spray fertilizer: In the high-yield fertilization of Chinese cabbage, in addition to the large amount of nitrogen, phosphorus and potassium, the application of medium and trace elements should also be considered. From the current problems in the production of Chinese cabbage, some areas are mainly the physiological deficiency of calcium and boron. You can choose to spray foliar fertilizer containing calcium, boron and iron.
