Why don't I grow Chinese cabbage?

Farmers who grow Chinese cabbage often encounter this phenomenon. Some Chinese cabbages have no heart, or grow to the bottom of the dish, or grow into cabbage seeds after bolting, but more often they grow to the bottom of the dish.

In fact, there are many reasons why Chinese cabbage is not stuffed, and the most important reason is the climate. For example, the low temperature and high humidity environment will cause various diseases of Chinese cabbage, which will not only cause Chinese cabbage to be blocked, but also cause Chinese cabbage to rot and die. Of course, improper fertilization and improper water supply in management will lead to insufficient Chinese cabbage, so it is necessary to combine the climate of Chinese cabbage growth period, rationally fertilize and water it, prevent and control pests and diseases in time and ensure the healthy growth of Chinese cabbage. In addition, if the planting density is too high, it will also cause poor growth and cover up the heart.

Planting time is too early, which is easy to cause the leaves of Chinese cabbage to grow white. Therefore, Chinese cabbage planted in the open air in the early north is mostly for eating cabbage seedlings, not for storing cabbage in winter. Chinese cabbage has good cold tolerance, but it doesn't like high temperature. If it is planted too early or the weather is too warm during the growth period of Chinese cabbage, it is easy to cause the phenomenon that the leaves of Chinese cabbage grow vigorously without wrapping their hearts. Therefore, planting in greenhouses and keeping the temperature at a constant temperature will not affect the growth of Chinese cabbage.

Chinese cabbage has a large water content, so it needs a lot of water in the growing period, but the imbalance of water supply will also affect the normal growth of Chinese cabbage. Therefore, according to the weather conditions, water in time when it is dry, and drain in time when it rains, especially in the heart of Chinese cabbage, to avoid water shortage. Covering fields with straw or wheat straw can effectively keep soil moisture.

In addition, improper fertilization will also lead to long leaves of Chinese cabbage, especially if nitrogen fertilizer is applied in a partial way, ignoring potassium fertilizer and phosphorus fertilizer, which will easily lead to white leaves. Spraying foliar fertilizer at the filling stage of Chinese cabbage can ensure the compactness of Chinese cabbage filling. However, Chinese cabbage suffers from virus diseases, soft rot, filariasis, aphids and other pests and diseases, and its growth is poor, which is also easy to cause the phenomenon of not filling the heart. Therefore, timely prevention and control of pests and diseases is also effective.

In fact, artificial wrapping can greatly improve the density of Chinese cabbage during the wrapping period as long as there are no pests and diseases. There is a process for growing Chinese cabbage here, that is, tying Chinese cabbage. During the Chinese cabbage wrapping period, the leaves of Chinese cabbage are bound manually to play the role of auxiliary wrapping, and then the Chinese cabbage is wrapped slowly and automatically later.

To sum up, Chinese cabbage loses its storage and edible value if it is not wrapped. In production, it should be prevented in time, combined with weather conditions, rational fertilization and watering, timely prevention and control of pests and diseases, supplemented by manual bandaging to promote bandaging.
