Abstract: does cabbage need to be watered immediately after fertilization?

Cabbage is the most common vegetable we eat in winter, and I like cabbage very much. it is not only cheap, but also has a variety of practices, and every taste is delicious. At present, it is in the growing period of Chinese cabbage. Here we will discuss the water and fertilizer management of Chinese cabbage.

Does cabbage need to be watered in time after fertilization?

In fact, whether cabbage needs to be watered directly after fertilization needs to be discussed in detail according to the local planting environment and planting habits. According to the general planting habits, most growers use fertilization and watering together, which is more conducive to the absorption of fertilizer by cabbage and can reduce the harm caused by excessive chemical fertilizer. However, some growers do not water in time after fertilization, in fact, the impact is not particularly great, the key is to look at the water and fertilizer management of the whole planting process. Water and fertilizer are very important in the growth of Chinese cabbage.

The problem of water and fertilizer in Chinese cabbage

The amount of fertilizer needed by Chinese cabbage is very large, and the largest amount of fertilizer needed in the growth process of Chinese cabbage is potassium fertilizer, followed by nitrogen fertilizer and phosphate fertilizer. The demand for fertilizer in the young seedling stage of Chinese cabbage is not very obvious, but the demand for fertilizer is very strong when the Chinese cabbage enters the rosette stage and the final heading stage. Scientific and reasonable fertilization can ensure the good growth of Chinese cabbage in the later stage.

First of all, there is the problem of base fertilizer, which is generally dominated by organic fertilizer, and the use of base fertilizer needs to consider many problems, such as the target output value of Chinese cabbage, soil fertility and so on. Under normal circumstances, about 5000 kg of barnyard manure is applied per mu, and in addition, with the use of chemical fertilizer, about 5 kg of urea, 15 kg of diamine and 8 kg of potassium sulfate are applied per mu.

The topdressing of Chinese cabbage is generally divided into three stages, the first is the seedling stage of Chinese cabbage, the second is the rosette stage, and the third is the heading stage, the fertilizer and water requirements are different in each period. Let's talk about it separately here.

First of all, the seedling stage, the amount of fertilizer needed in the seedling stage of cabbage is not very large, the first is to raise seedling fertilizer, generally when the cabbage grows to three or four true leaves, at this time, according to the growth status of cabbage seedlings, about 5 kilograms of ammonium sulfate per mu is applied. Immediately after fertilization, cooperate with watering. The second topdressing at seedling stage is generally carried out about ten days after transplanting, generally topdressing 5 kilograms of urea, preferably buried in the shallow ditch next to cabbage.

The second is the rosette stage of Chinese cabbage, the fertilizer requirement of this period should be significantly increased, during this period, the general application of ternary compound fertilizer is about 20 kg per mu. It is best to cooperate with watering after fertilization to avoid the lack of water in cabbage, resulting in fertilizer damage to cabbage.

The last is the heading period of Chinese cabbage, which is mainly based on potash fertilizer to promote the heading of Chinese cabbage. Generally, about 10 kg of urea and 10 kg of potassium sulfate are applied per mu. During this period of time, the weather is relatively cold, so it is not suitable for overwatering, so it is best to use small water when watering. In addition, it is best to stop watering a week or so before harvest.
