How to manage the latest autumn cabbage at seedling stage

At present, it is the period of planting autumn cabbage in many areas, and autumn cabbage in many areas has also entered the seedling stage management link, so how to manage autumn cabbage in the seedling stage in order to achieve high yield? Let's take a look at the detailed introduction with the editor.

1. Seedlings during seedling period

The problem of planting density must be considered at the seedling stage. Too dense or too thin planting will affect the yield of autumn cabbage in the later stage. generally speaking, the distance between autumn cabbage should be kept at about 25-30 cm. On the other hand, when the cabbage grows two true leaves, it can meet again, and when it grows 3-4 true leaves, it can meet again. At the same time, the seedlings with strong growth should be retained, and the seedlings with weak growth and infected diseases and insect pests should be removed by hormone to ensure the strong growth of seedlings.

2. Fertilizer and water management

The requirement of fertilizer and water for Chinese cabbage in the growth process is still relatively large, and the basic fertilizer must be fully applied before planting. After planting, it should be properly watered according to the field growth situation of Chinese cabbage to promote the growth and development of Chinese cabbage. However, in continuous rainy weather, we must pay attention to timely drainage and waterlogging, so as to avoid stagnant water leading to root rot or root rot of Chinese cabbage, which is extremely disadvantageous to the growth of Chinese cabbage and has a great impact on the yield in the later stage.

3. Pest control

In the seedling stage of Chinese cabbage, attention should also be paid to the prevention and control of diseases and insect pests. The temperature in the early autumn is still relatively high, which is the peak period for the occurrence of cabbage insects and night moths. In the case of serious pests, cabbage seedlings will basically become bare in 2-3 days, so it is necessary to take good control measures. In addition, the occurrence of diseases such as standing blight, quenching disease and downy mildew at the seedling stage will also seriously affect the growth of Chinese cabbage and reduce the yield, so it is important for the prevention and control of diseases and insect pests at the seedling stage, but the prevention is more active.
