Latest Key Points for Seedling-Stage Management of Autumn Chinese Cabbage Explained in Detail
Chinese cabbage is the most common vegetable, and many families grow some, while autumn is just the good season for planting Chinese cabbage, especially in Northeast China, where many people are now busy planting Chinese cabbage. To achieve high yield and high quality in Chinese cabbage cultivation, seedling-stage management is extremely important. Now let's take a look together with the editor at the key points of Chinese cabbage seedling-stage management.
1. Thinning
Autumn Chinese cabbage is generally grown by direct sowing, so after sowing and emergence, the Chinese cabbage must be thinned. Thinning Chinese cabbage can be divided into two rounds. The first thinning is carried out after the Chinese cabbage has grown two true leaves, removing the seedlings that are too densely growing and weaker in growth; the second thinning is carried out when the Chinese cabbage has grown 3-4 true leaves. In this thinning, the plant and row spacing must be planned well, generally keeping a spacing of about 25-30 cm, and only retaining seedlings that are robust in growth and free of pests and diseases.
2. Fertilizer and Water Management
⟦NL>Although Chinese cabbage is a water-loving crop, it is not tolerant of waterlogging. To prevent Chinese cabbage from encountering long periods of rainy weather during the growing period, it is best to choose ridge planting when planting. This not only helps field ventilation, but also helps promptly drain accumulated water from the field after rain, avoiding root rot and death from waterlogging. After planting, the water needed for Chinese cabbage growth must be replenished in time. Chinese cabbage has poor heat tolerance, and the temperature at noon in autumn is still very high, so watering should be done reasonably to lower the ground temperature and also keep the soil moist. In addition to reasonable irrigation, timely topdressing is also needed. Before planting, sufficient base fertilizer should be applied, and during the seedling stage, rosette stage and heading stage, topdressing should be done in time, which can effectively increase the yield of Chinese cabbage.
3. Binding Management
When growing Chinese cabbage, many people find binding Chinese cabbage troublesome, but older people believe that binding Chinese cabbage is an indispensable step. In fact, if you want high yield from Chinese cabbage, this binding step is very important. Binding is generally carried out half a month before harvest. Sweet potato vines or rice straw can be used. First, gently lift the outer leaves of the Chinese cabbage, then tie them with rice straw or sweet potato vines at two-thirds of the height of the Chinese cabbage. Do not tie too tightly, as it easily affects the Chinese cabbage forming a heart. Note that watering must not be done within 3-4 days before binding, and after binding a small amount of water can be given to promote the growth of Chinese cabbage.
4. Pest and Disease Control
The pests and diseases of Chinese cabbage include aphids, damping-off, seedling blight, downy mildew, etc. Their occurrence seriously affects the growth of Chinese cabbage and also reduces the yield and quality of Chinese cabbage. Therefore, timely control is needed, mainly focusing on prevention and combining prevention with control. During the peak period of pests and diseases, spraying should be done in time to prevent the spread of pathogens and pests.
