A Detailed Explanation of the Latest Fertilization Rules and Methods for Chinese Cabbage
Everyone must have eaten Chinese cabbage. The stir-fried Chinese cabbage is very sweet. Although the market price of Chinese cabbage is not high, there are still many people selling and growing Chinese cabbage. Because the market demand for Chinese cabbage is very large, growing Chinese cabbage on a large scale is still something that can be appropriately considered. In the process of growing Chinese cabbage, fertilizer is the most important thing. Only by applying fertilizer well can the yield of Chinese cabbage be guaranteed. So what are the fertilization rules for Chinese cabbage? How should fertilizer be applied? Let's take a look together!
1. Fertilizer requirement rules
During the growing process, Chinese cabbage needs a large amount of fertilizer, and it also has requirements for the nutrient composition of the fertilizer. The nutrient in greatest demand is potassium fertilizer, followed by nitrogen fertilizer, and finally phosphorus fertilizer. During the seedling stage, Chinese cabbage has the lowest fertilizer demand, but sufficient nutrients are still needed to ensure the growth of Chinese cabbage. After passing through the seedling stage and entering the rosette stage, the demand for nutrients increases rapidly. The nutrient level at this time will determine the final quality and yield of the Chinese cabbage. The fertilizer required during the final heading stage is no less than that required during the rosette stage, mainly potassium fertilizer and an appropriate amount of nitrogen fertilizer.
2. Fertilization methods
(1) Base fertilizer
Before planting Chinese cabbage, the base fertilizer in the soil should be applied sufficiently to improve soil fertility. Farmyard manure can be used as the base fertilizer. Because farmyard manure is rich in nutrients and has strong fertility, applying sufficient base fertilizer is very important for the growth of Chinese cabbage. The specific amount of fertilizer applied mainly depends on the planting area. Usually, the amount of base fertilizer per mu is about 4800-5200 kg, and an appropriate amount of compound fertilizer is then added.
(2) Seedling-promoting fertilizer
Seedling fertilizer is also very important for Chinese cabbage, because the seedlings are very thin and weak and need sufficient nutrients to promote seedling growth, increase the growth rate, and strengthen the resistance of Chinese cabbage. Quick-acting fertilizers such as ammonium nitrate can be used as seedling fertilizer, applied into each planting hole before sowing, and watered sufficiently after sowing.
(3) Plant-development fertilizer
Plant-development fertilizer refers to the topdressing work during the rosette stage of Chinese cabbage. The rosette stage determines the later yield, so fertilizer application at this stage should not be stinted. Reasonable fertilization and watering are important conditions for providing for the growth of rosette leaves, but the amount should also be noted to prevent excessive use from causing excessive vegetative growth and affecting the heading time of Chinese cabbage. Usually, when a small portion of the plants have already begun to head, it is time to apply plant-development fertilizer.
(4) Heading fertilizer
Heading fertilizer has already reached the final stage of Chinese cabbage growth, and at this time the fertilizer requirement also increases greatly. Begin applying heading fertilizer when the Chinese cabbage has not yet fully formed heads. Note to apply more potassium fertilizer, using fertilizer with strong fertility and long-lasting fertilizer effect as heading fertilizer. However, the amount still needs attention, as too little or too much will have a certain effect on the final result of heading. It is best to mix farmyard manure with chemical fertilizer and apply it by the furrow method.
The above is a brief introduction to the fertilizer requirement rules and fertilization methods for Chinese cabbage. No matter what crop it is, fertilizer nutrients are the most important. Fertilizing crops is equivalent to people eating meals. If you do not eat enough, how can you have the strength to go to work? It is the same principle. Therefore, during the planting process, do not let Chinese cabbage “go hungry”, so that the yield can be further increased.
