When should I topdress Chinese cabbage?
When it comes to cabbage, no one will feel strange. Every autumn and winter, there is a great demand for cabbage in the vegetable market, so there are also many farmers who grow cabbage.
Especially, Chinese cabbage planted in the open air in autumn in northern China is not only delicious but also has high nutritional value, which is very popular with consumers.
In the process of planting Chinese cabbage, sufficient water and fertilizer are needed to promote the growth of leaves, increase the weight of leaf bulbs, make the core compact and the leaves tender, so that Chinese cabbage has good commercialization.
In the actual planting process, farmers often encounter various problems, such as loose leaves, low yield, fertilization and so on.

How to manage high-yield and high-quality Chinese cabbage
Cabbage is a cold-tolerant and fertilizer-tolerant vegetable crop. The taste and nutritional value of cabbage planted in the open air after autumn are much higher than those planted in greenhouse.
However, Chinese cabbage has weak root system, poor resistance to stress and diseases and insect pests, and it is difficult to plant in the open air.
It is easy to cause diseases due to light, temperature and other reasons, resulting in reduced production. Farmers need to do a good job in fertilization management during the growth period of Chinese cabbage, which can significantly improve the resistance, yield and quality of Chinese cabbage.

Fertilization techniques for increasing yield, improving quality and preventing diseases of Chinese cabbage
Tip 1: Apply base fertilizer.
In the process of agricultural planting, fertilization is the best way to promote crop growth, and the top priority of crop fertilization management is topdressing base fertilizer.
The root growth of Chinese cabbage is poor, and the significance of topdressing base fertilizer is more prominent. Before planting Chinese cabbage, the soil should be ploughed and tidied up.
Organic fertilizer must be applied again before soil ploughing, which can improve soil moisture and air permeability and is of great significance to promote the root growth of Chinese cabbage. Proper compound fertilizer should be applied before sowing Chinese cabbage.
The quick-acting components in compound fertilizer can promote seed germination or seedling awakening, and the long-term effect of compound fertilizer can provide sufficient nutrient guarantee for seedling growth.
The soil is fertile, the water is good, and Chinese cabbage grows well.
Tip 2: Be diligent in topdressing.
However, there are many similarities between crops and people. Although Chinese cabbage is relatively cold-tolerant, its cold tolerance is directly related to its growth.
Therefore, in the growth period of Chinese cabbage, it is not only necessary to provide nutrients by base fertilizer, but also to add topdressing at the peak of fertilizer use, such as flowering stage, heading stage.
The liquid fertilizer fulvic acid from Tianqing Mine is mixed with calcium, magnesium, boron and zinc, diluted with water, and then washed or sprayed to quickly supplement various large, medium and trace nutrients, enhance leaf photosynthesis and promote nutrient synthesis.
Fertilization in this way can accelerate the growth of stems and leaves of Chinese cabbage, and supplement calcium and boron can prevent and treat diseases such as dry heartburn of Chinese cabbage and improve the stress resistance of Chinese cabbage. At the same time, it can also reduce soil-borne diseases and bacterial reproduction. Chinese cabbage has high yield, good stem quality, few diseases and strong cold and drought resistance.
Chinese cabbage grows well, with high yield and good leaf quality.
Tip 3: Comprehensive fertilization
No crop can be satisfied only by topdressing nitrogen, phosphorus and potassium, which is why topdressing nitrogen, phosphorus and potassium is the reason for most of the agricultural planting process.
This is because crops have a great demand for large elements such as nitrogen, phosphorus and potassium, but little demand for medium and trace elements such as calcium, magnesium, boron, zinc, copper, iron and manganese, which also play a decisive role in the growth of Chinese cabbage.
However, with a large number of topdressing and years of planting, there are few trace elements in farmland soil.
If crops grow out of date and trace elements are missing, there will be element deficiency, which will reduce the yield and quality. Therefore, the fertilization of Chinese cabbage should be comprehensive and not limited to a large number of elements.
