Cabbage is one of the indispensable vegetables in our lives. It grows fast and has a short growth cycle, but improper management will cause the cabbage to not grow a heart (wrap a heart), affecting yield and quality. Reasons why Chinese cabbage does not grow heart:1. Sowing too early Unable to adapt to climatic conditions leads to lack of patience. 2. Lack of water During the growth process of cabbage, the water requirement is very large. Failure to water it in time will cause the cabbage to not grow heart. 3. Improper fertilization During the growth process of cabbage, excessive application of nitrogen fertilizer may cause the leaves to grow wildly, while not paying enough attention to the application of phosphorus and potassium fertilizers, resulting in excessive nitrogen fertilizer and insufficient phosphorus and potassium fertilizers, causing the cabbage to not grow core. 4. Improper drainage If there is too much rain, the fields will be waterlogged and humid, which will affect the growth of the cabbage roots and cause the cabbage to not grow heart. 5. Pests and diseases During the growth process, Chinese cabbage is susceptible to many diseases and pests, such as soft rot, dry heart disease, powdery mildew, cabbage worm, diamondback moth, aphids, etc. The occurrence of diseases will affect the growth of cabbage and cause the cabbage to not grow heart. We all know that cabbage is a leafy vegetable and one of the most commonly eaten vegetables. The quality of the cabbage is greatly affected by whether the cabbage is firm or loose. What method can be used to make the cabbage wrap faster? 1. Scientific topdressing in stagesChinese cabbage is a leafy vegetable that requires more nitrogen, but the more nitrogen the better. After the cabbage is planted, until the cabbage heads, it mainly grows for nutrition. Using more nitrogen fertilizer can promote the growth of cabbage plants to be larger and greener. On the basis of sufficient base fertilizer and farmyard manure, apply more nitrogen-based fertilizer. In this way, the cabbage plants grow rapidly, and then adding phosphorus and potassium fertilizers will make the cabbage grow stronger and more vigorous. When the cabbage is in the head stage, high-nitrogen and high-potassium compound fertilizer is applied, about 25 to 30 kilograms per mu of land. The cabbage will not be depleted of fertilizer, so it will naturally grow faster when it is in the head stage. |
