Causes and Control methods of rotting Root of Chinese Cabbage

Rotting root of Chinese cabbage during planting is a common disease, which will lead to gradual withering and death of Chinese cabbage, which seriously affects the yield and quality and reduces the economic benefits of farmers. So what is the reason for the rotten roots of Chinese cabbage? What about the rotten roots? Let's introduce it in detail.

1. Rotting root caused by retting root

Chinese cabbage is a semi-cold vegetable, like a mild and cold climate, neither cold nor heat-resistant, but also like a humid environment, but not resistant to waterlogging. When planting in the environment of high temperature or low temperature, in case of overcast and rainy season, too much water in the soil during heavy rain will lead to root necrosis due to hypoxia and root retting. In addition, if Chinese cabbage is in the period of high temperature in the early growth period, there will be high temperature retting root; on the contrary, in the later growth stage of Chinese cabbage, if the temperature is too low, there will be low temperature retting root.

2. Rotting roots caused by soft rot

Soft rot is also one of the causes of rotting roots of Chinese cabbage. It is easy to occur soft rot when soaked roots are planted in high-lying and water-prone plots. In addition, too much nitrogen fertilizer is applied, or plants are bitten or damaged by insect pests, resulting in germs invading and infecting soft rot. Soft rot mainly harms the rhizome, the petiole appears water stains, the outer leaves lose water and wither, and when the disease is serious, the rhizome rots. It is full of yellow sticky matter, giving off a special stench and causing the whole plant to rot.

3. Preventive measures for retting roots.

Select the land with high topography and good drainage to plant, in order to avoid the phenomenon of retting roots caused by too much water in the soil, in the early growth stage, in case of high temperature climate, shading measures can be taken again to prevent high temperature retting roots; in the later growth stage, plastic film mulching and fertilization can be used to improve low temperature and prevent low temperature retting roots. In planting, intertillage can be used to weed, increase the permeability of the plant, so that the root system can breathe and stretch normally. In addition, in the later growth stage, intertillage can also increase the low temperature and reduce the probability of freezing injury. It is necessary to drain water in time after rain to prevent the phenomenon of rain and waterlogging, and flood irrigation is strictly prohibited when watering, so as to avoid retting roots.

4. Control methods of soft rot.

Precautions against soft rot should also avoid planting on low-lying, sticky plots, and avoid Solanaceae, melons and fruits, and cruciferous vegetables. In the onset of the disease can be used agricultural streptomycin sulfate or neophytomycin spray prevention and treatment, once a week, according to the condition of continuous spraying 2-3 times.

The above are the causes and control methods of rotten roots of Chinese cabbage. I hope I can help you. If you want to know more about vegetable cultivation, please follow us.
