How to manage autumn Chinese cabbage at the seedling stage? A detailed explanation of the latest key technical points
Right now is the period when many regions are planting autumn Chinese cabbage, and in many regions the autumn Chinese cabbage has also entered the seedling-stage management phase, so how should autumn Chinese cabbage be managed at the seedling stage to achieve high yields? Follow the editor to take a look at the detailed introduction below.
1. Thinning at the seedling stage
At the seedling stage, the issue of planting density must be considered well. Planting too densely or too sparsely will both affect the later yield of autumn Chinese cabbage. Generally speaking, the spacing of autumn Chinese cabbage should be kept at about 25-30 cm. When the cabbage has grown two true leaves, thinning can be carried out once, and when it has grown 3-4 true leaves, thinning can be carried out again. While thinning, seedlings with stronger growth should be retained, while seedlings with weak growth and those infected by pests and diseases should be removed, ensuring that the seedlings grow strong and healthy.
2. Fertilizer and water management
Chinese cabbage has a relatively large demand for fertilizer and water during its growth process. Before planting, the base fertilizer must be applied in sufficient quantity. After transplanting, watering should be done appropriately according to the field growth conditions of the Chinese cabbage to promote its growth and development. However, during continuous rainy weather, attention must be paid to timely drainage and waterlogging prevention, so as to avoid root rot or root rot disease caused by water accumulation, which is extremely unfavorable to the growth of Chinese cabbage and also has a relatively large impact on the later yield.
3. Pest and disease control
At the seedling stage of Chinese cabbage, attention should also be paid to the prevention and control of pests and diseases. In the early autumn, the temperature is still relatively high, and it is the peak period for the occurrence of cabbage caterpillars and armyworms. When the pest infestation is severe, basically in 2-3 days the cabbage seedlings will be stripped bare, so control measures must be taken well. In addition, at the seedling stage, diseases such as damping-off, seedling blight, and downy mildew will also seriously affect the growth of Chinese cabbage and at the same time reduce the yield, so pest and disease control at the seedling stage is certainly important, but prevention is even more proactive.
