The latest course of Management techniques and methods in the Middle and late stage of Chinese Cabbage

Chinese cabbage is a very common vegetable in China, which is welcomed by many people. Although the market price is not very high, but the market demand is large, so its economic value is still very good. So now the planting area of Chinese cabbage is also relatively large, when planting Chinese cabbage, we must do a good job in management, especially in the middle and later stages. So today, the editor brings you the management technology of Chinese cabbage in the middle and later period. Let's have a look!

1. Rosette management

The rosette stage is a critical period for the growth of Chinese cabbage, when the demand for water and nutrients is very large. Therefore, during this period, we must do a good job in water and fertilizer management and rational watering. Pay attention to Chinese cabbage squatting seedlings, do not flood irrigation, mainly with small water irrigation. After the rainy season, we should pay attention to drainage and do a good job of ploughing to avoid the hardening caused by too much soil moisture. Watering can be carried out together with topdressing. Properly spraying new high lipid film can improve fertilizer efficiency, enhance disease resistance and increase yield of Chinese cabbage.

2. Pericardial period management

The management of Chinese cabbage in the heart stage has a direct impact on the yield, and the disease resistance of Chinese cabbage in this period is relatively weak. Diseases and insect pests are very easy to occur, so we must do a good job in the prevention and control of diseases and insect pests, such as downy mildew, black rot and aphids. In Chinese cabbage ridge before re-prevention, spraying pesticides should pay attention to comprehensive and thorough, if it rains after spraying, then make up spraying in time. Then remove the diseased plant, avoid expanding the affected area, and do a good job of disinfection at and around the affected plant, so as to ensure the healthy growth of Chinese cabbage.

3. Pest control

Pest control of Chinese cabbage is essential in the middle and later stage. For example, cabbage worm, beet armyworm, and so on, these pests will not only eat all parts of Chinese cabbage, resulting in the loss of commercial value of Chinese cabbage, affecting the efficiency of planting. Moreover, it may also carry germs and cause a variety of diseases, such as aphids can carry virus diseases, which seriously affect the growth of Chinese cabbage and reduce the quality and yield. Therefore, we should do different control work according to different pests, such as Pieris rapae and beet armyworm can be controlled by polyester drugs, and aphids can be controlled by aldicarb.

4. Disease control

Of course, disease control is also an indispensable management work for planting Chinese cabbage. The common diseases and insect pests of Chinese cabbage are soft rot, virus disease and so on. There are different diseases in different growth periods of Chinese cabbage. For example, soft rot is easy to occur from rosette stage to pericardial stage, and downy mildew is easy to occur from seedling stage to heading stage. Therefore, when we are planting, we must do a good job in management, timely drainage, spraying pesticides and strengthening prevention. To understand the symptoms of various common diseases, it is convenient to know what the disease is in time after the disease, and to make corresponding measures.

The above is a brief introduction to the management technology of Chinese cabbage in the middle and later stage. The management of Chinese cabbage is very important, which is directly related to the yield and quality of Chinese cabbage, so we must manage it carefully when planting. That's all for today's introduction. This article is for reference only. I hope it can help you all.
