Detailed Explanation of Key Points of Scientific Fertilization Techniques for Cabbage
Cabbage is one of the common vegetables in our daily lives. It is rich in nutrients and has the effects of benefiting the spleen and stomach, relieving urgency and stopping pain. It can also treat symptoms such as abdominal bloating and lethargy, and regular consumption also has an anti-cancer effect. If you want to increase its yield during cultivation, mastering fertilization techniques is the key point. So how should cabbage be fertilized? Follow the editor to take a look at cabbage fertilization techniques.
1. Fertilizer Requirements and Characteristics
Cabbage has strong adaptability to soil and is a fertilizer-loving and fertilizer-tolerant crop. It is suitable for growing in sandy loam soil with deep soil layers, loose and fertile texture, rich organic matter, and strong water and fertilizer retention capacity. Cabbage has a relatively high demand for nitrogen fertilizer. In an environment with sufficient nitrogen fertilizer, its chlorophyll content is high, and the aboveground stems and leaves grow vigorously, which helps increase yield. However, if there is too much nitrogen fertilizer and relatively little phosphorus and potassium fertilizer, it will cause the plant to grow excessively, with large and thin leaves, loose heading or no heading, lower quality, affecting commercial value, and it is also prone to pests and diseases. Phosphorus fertilizer can promote the differentiation of leaf primordia, increase leaf differentiation, and improve yield, while potassium fertilizer can promote the transport of nutrients, make the head compact, and improve quality, and it is indispensable during cabbage growth.
2. Fertilization Principles
When fertilizing cabbage, the principle of giving priority to base fertilizer and supplementing with topdressing should be implemented, achieving a balanced combination of organic fertilizer and chemical fertilizer. In addition, when topdressing, attention should be paid to the ratio of nitrogen, phosphorus, and potassium fertilizers, generally with nitrogen fertilizer as the main component and a reasonable combination of phosphorus and potassium fertilizers. During the rosette stage and heading stage of cabbage, some trace elements such as calcium and boron should be appropriately supplemented to avoid heading failure or the occurrence of diseases. After fertilization, water should be applied so that the fertilizer can be absorbed by the plant as soon as possible and the fertilizer utilization rate can be improved.
3. Applying Sufficient Base Fertilizer
After selecting a good plot of land, half a month before sowing or transplanting cabbage, when preparing and plowing the land, apply 4000-5000 kg of fully decomposed organic fertilizer or farmyard manure per mu, combined with 50 kg of ternary compound fertilizer, and plow it into the soil layer together with deep plowing, or mix it evenly with the soil. The amount of base fertilizer applied generally accounts for 50%-60% of the total fertilization amount, and it can provide sustained fertility for cabbage growth.
4. Timely Topdressing
In addition to applying sufficient base fertilizer, cabbage has a great demand for fertilizer during several growth stages, so efficient fertilizer should be topdressed in a timely manner to provide what is needed for its growth. After transplanting, in order to promote strong seedling growth, apply 10-15 kg of nitrogen fertilizer per mu. When fertilizing, it is best to water and wash it through to reduce the fertilizer concentration, so as to avoid high-concentration fertilizer burning the seedling roots. When cabbage continuous cropping is formed, a large amount of fertility is also needed at this time. At this time, 20-30 kg of nitrogen-potassium compound fertilizer should be applied per mu, generally applied in furrows. Finally, there is one more time during the heading stage. Fertilizing at this time is to improve the yield and quality of cabbage. Generally, 10-15 kg of high-nitrogen compound fertilizer is applied, and some potassium fertilizer should also be combined.
