How to fertilize Chinese cabbage? The single yield of Chinese cabbage is very high, so there are more requirements for fertilizer. If you want high yield of your own Chinese cabbage, how to apply fertilizer is very important. The following is a summary of the six major fertilization points and precautions for Chinese cabbage, and we will come to study if necessary.
First, the characteristics of fertilizer
In the vegetative growth phase of Chinese cabbage, adequate nitrogen nutrition is of great significance. The different growth cycles of Chinese cabbage, the demand conditions for fertilizers are also different, the absorption during seedling period is less, and the rosette period begins to increase. The core of the core absorbs the most nutrients.
Second, clever application of seedlings
When the cotyledons of Chinese cabbage grow out, they also have the ability to absorb water and absorb fertilizer. If there is insufficient base fertilizer or no fertilizer, 5 to 7 kg of urea can be applied per acre. The focus of fertilization is small seedlings and weak seedlings.
Third, the application of organic fertilizer
Applying enough base fertilizer is the basis for high yield for many crops. Chinese cabbage is also suitable for old crops, and new vegetable plots can be re-applied.
Fourth, attach importance to the application of potash
For Chinese cabbage, increasing potassium fertilizer can improve disease resistance. Generally, the amount of potassium applied is 15 kg of potassium chloride or 20 kg of potassium sulfate. A small amount of ash can also be applied in the absence of potash.
Five, reasonable topdressing
Generally, they are grasping the beginning of the seedling group and entering the beginning of the package and the topping of the rosette twice. At this stage, the Chinese cabbage can increase the amount of topdressing. The fertilizer should be based on nitrogen fertilizer, and the phosphorus and potassium fertilizers can be applied together.
Six, matters needing attention
If the nitrogen supply in the growth stage of Chinese cabbage is too small, Chinese cabbage will be severely reduced; if it is applied too much, it will not be resistant to storage. Therefore, it is very important to properly control the required measurement.
The above is the main point of fertilization of Chinese cabbage today. I hope to help all the novice farmers, and also welcome the old farmers to share more senior experiences!
