The latest course of fertilization techniques and methods for cabbage

Cabbage is one of the common vegetables in our life, it is rich in nutrition, but also beneficial to the spleen and stomach, emergency analgesic effect, but also can treat abdominal ledger, drowsiness and other symptoms, often eat and prevent cancer. If you want to increase its yield when planting. Mastering fertilization technology is the key point, so how to fertilize cabbage? Come with the editor to take a look at the fertilization techniques of cabbage.

1. Characteristics of fertilizer requirement

Cabbage has strong adaptability to soil and is a fertilizer-loving and fertilizer-tolerant crop. It is suitable to grow in sandy loam with deep soil layer, loose and fertile soil, rich in organic matter and strong water and fertility conservation. Cabbage has more demand for nitrogen fertilizer. Under the environment of sufficient nitrogen fertilizer, it has high chlorophyll content and vigorous growth of aboveground stems and leaves, which is helpful to increase the yield. However, if there is too much nitrogen fertilizer and less phosphorus and potassium fertilizer, it will lead to overgrowth of plants, large and thin leaves, not tight or non-heading, low quality, affecting commodity value, and easy to cause diseases and insect pests. Phosphate fertilizer can promote the differentiation of leaf primordium, increase leaf differentiation and increase yield, while potassium fertilizer can promote the transport of nutrients, enrich the leaf ball, improve the quality, and is essential for the growth of cabbage.

2. Principles of fertilization

When applying fertilizer, cabbage should implement the principle of giving priority to base fertilizer and supplemented by topdressing to realize the content collocation of organic fertilizer and chemical fertilizer. In addition, attention should be paid to the proportion of nitrogen, phosphorus and potassium fertilizer, which is generally dominated by nitrogen fertilizer and reasonably matched with phosphorus and potassium fertilizer. In the rosette and heading stage of cabbage, some trace elements such as calcium and boron should be properly supplemented to avoid the occurrence of diseases caused by the failure of heading. After fertilization, the fertilizer should be watered so that the fertilizer can be absorbed by the plant as soon as possible and improve the fertilizer utilization rate.

3. Apply sufficient base fertilizer

After selecting a good plot, half a month before cabbage sowing or planting, when ploughing the land, apply 4000-5000 kg of fully mature organic fertilizer or farm manure per mu, in combination with 50 kg of ternary compound fertilizer, combined with deep ploughing to turn into the soil layer, or mix evenly with the soil, the application rate of base fertilizer generally accounts for 50% 60% of the total fertilizer application, which can provide continuous fertility for cabbage growth.

4. topdressing at the right time

In addition to applying sufficient base fertilizer, cabbage needs a lot of fertilizer at several growth stages, so it is necessary to topdressing and efficient fertilizer in time to provide its growth needs. In order to promote the growth of seedlings after planting, 10-15 kg of nitrogen fertilizer was applied per mu, and it was best to water and wash it to reduce the concentration of fertilizer so as not to burn the roots of seedlings with high concentration of fertilizer. When cabbage continuous cropping is formed, a lot of fertility is also needed, and 20-30 kg of nitrogen and potassium compound fertilizer per mu is needed. The last time is in the heading period, when fertilization is to improve the yield and quality of cabbage, generally apply high-nitrogen compound fertilizer 10-15 kg, but also with some potash fertilizer.

The above is the fertilization technology of cabbage, hope to help you, want to know more knowledge of cabbage planting, please follow us.
