Cabbage is also called cabbage. Do you know how to fertilize cabbage? 1, soil leveling in the field, about 15-20 days before transplanting with base fertilizer, turn the field over, let it bake for about 10 days, soil leveling again, rough leveling once, fine leveling once two days before transplanting, and then apply base fertilizer, 1 mu. In order to centralize fertility, base fertilizer can be applied to the planting wedge immediately, and then the hole soil can be turned over and mixed until it is dry, so that it can be transplanted. After transplanting, each seedling is watered with a little water, 0.5KG per plant, and then watered once a day until it survives.

2. After topdressing, irrigation and drought resistance, topdressing is carried out for the first time. 1 mu 10% of human and animal manure is topdressing, and 600-800KG is applied per mu. After that, topdressing is carried out for 3-4 times at the spreading stage, before heading and in the middle and late stage, with the topdressing concentration of 30-40%, and the total amount is about 1 mu 1500KG. Topdressing is mainly based on farm manure and pig manure, and a little chlorine organic fertilizer can be added, generally with 0 nutrient per100kg. Then, in the normal growth period, organic fertilizer should only be added less than twice to prevent the quality from being harmed.

When the temperature is high, the sun is strong, and it is sunny for a long time without rain, corresponding measures can be chosen to carry out drought resistance by lifting water and watering seedlings or watering wet seedlings. Irrigation is carried out at dusk on sunny days, and the remaining water in the ditch will be discharged immediately after irrigation, so as to prevent the root from being retched and endangering the growth and development. In addition, the topdressing of spring cabbage is different from that of autumn cabbage. In the case of the same base fertilizer, spring cabbage is generally dominated by watering clear water to fight drought and protect seedlings in autumn and winter, but watering clear water is not suitable for too much. As long as the vegetable seedlings rise well and there is no shortage of water, they cannot be watered. After the early spring, the growth and development of Chinese cabbage in spring is rapid, so it is necessary to topdress it with heavy fertilizer with the concentration of 40% up and down for 2-3 times, 1 time when the leaves among plants are covered with soil, which is called "line closure", and 1-2 times before heading, middle and late. 1 mu NPK fertilizer10-20kg.

The above is the knowledge introduction about cabbage. Before planting cabbage, there should be base fertilizer, and some human excrement and urine liquid, calcium phosphate or plant ash can be put in. In the process of cabbage growth, it is necessary to carry out reasonable topdressing and irrigation to ensure that the fertilizer and water in the cabbage field can be sufficient, which will help its growth. It is very important to do well the fertilization management of cabbage, which can effectively improve the yield and quality of cabbage, and growers should pay attention to it.
