How to prevent root rot during cabbage planting?

Abstract: rotten roots appear during cabbage planting, how to prevent and cure them?

Rotten root and rotten heart are two major diseases that often occur in the process of planting Chinese cabbage. Once the disease occurs, it will not only lead to a decline in the yield and quality of Chinese cabbage, but also lead to death, which will greatly reduce the economic benefits of Chinese cabbage growers. So how to solve the root rot disease of Chinese cabbage? Let's first understand why there are rotten roots, and then find a way to solve the problem.

The cause of rotten roots

In production, Chinese cabbage with rotten roots basically occurs in fields with high humidity, but because the rotting roots of Chinese cabbage basically occur in October-December, and the weather is cool and the humidity is relatively high in these months, for example, there is more dew in the morning and evening, which virtually increases the humidity in the field, and Chinese cabbage grows very fast, and there is more demand for water and fertilizer, so it is slightly dry, and farmers not only go to irrigate. Therefore, Chinese cabbage often appears root rot disease due to excessive soil moisture in the field, and the phenomenon of disease occurs in areas due to the spread in the field. Therefore, the rotten roots of Chinese cabbage can also be attributed to root rot or retting roots.

How to avoid rotting roots of Chinese cabbage

For solving the rotten root of Chinese cabbage, it is more reliable to start with cultivation measures, such as planting Chinese cabbage in Duilong, avoiding planting in low-lying areas, avoiding stagnant water in the field, resulting in excessive soil moisture in the roots. at the same time, the field as a whole should be flat to avoid uneven, after watering, the flow in the field can be uniform to avoid local stagnant water. At the same time, the drainage performance of the field is better, for example, continuous rain often occurs in October, and under the changed circumstances, the water in the field can be discharged in time, which can greatly reduce the occurrence of rotting roots. However, the most important thing is that all Chinese cabbage growers must pay attention to small water irrigation when watering, preferring a small number of times rather than a flood irrigation.

At the same time, if the disease in the field is more serious, when planting Chinese cabbage, we should also consider buying disease-resistant Chinese cabbage varieties. During the onset of root soft rot in the field, streptomycin sulfate can be sprayed to treat the disease, and two or three consecutive sprays can alleviate the symptoms of the disease in the field.

To sum up, we still focus on management for the rotten roots of Chinese cabbage. Scientific watering and fertilization and timely field management can greatly reduce the incidence of root rot of Chinese cabbage in the field. therefore, it is once again suggested that friends who plant Chinese cabbage go to the field to inspect as often as possible, pay close attention to the growth of the field, once the disease is found, timely drug prevention, to avoid the spread of the disease.
