The latest Technical and method course of Fertilizer and Water Management of Chinese Cabbage

Everyone must have eaten Chinese cabbage. Although it is cheap and common, its nutritional value is very high. It is rich in nutrients and has a large market demand in our country. Now the planting area of Chinese cabbage is also relatively wide, when planting Chinese cabbage, we should do a good job in fertilizer and water management. So what exactly should be done? The following editor brings you the fertilizer and water management technology of Chinese cabbage, let's have a look!

1. Fertilizer and water management in germination period.

Water is an indispensable condition for germination of Chinese cabbage seeds. If there is a high temperature stage of Chinese cabbage seeds after sowing, then in order to improve the germination ability of Chinese cabbage seeds. To do a good job of watering, but also can reduce the soil temperature. But water should not be too much, if there is a cloudy and rainy day after sowing, then less or no watering can be done. If it produces stagnant water, it should be drained in time. Adequate base fertilizer should be applied before sowing, and there is no need for topdressing from sowing to the ungerminated stage. If the base fertilizer is insufficient, a small amount of seed fertilizer can be applied appropriately.

2. Fertilizer and water management at seedling stage.

The growth of Chinese cabbage in seedling stage is relatively small, so the demand for water and fertilizer is relatively small. However, the roots of Chinese cabbage seedlings are not very developed, and the ability to absorb water and fertilizer is not strong. So we still have to provide sufficient water and nutrients for the seedlings according to the changes of climate and weather. Control the amount of water according to the change of soil weather and soil moisture. Then apply the seedling fertilizer properly together with watering to control the amount of fertilizer. For some weak seedlings, some chemical fertilizers should be applied properly, mainly by digging ditches and burying them, keeping the distance between 5cm and the roots, avoiding root burning, and watering properly after each topdressing.

3. Fertilizer and water management in rosette stage.

After entering the rosette stage, the roots of Chinese cabbage will occur in large numbers, and the growth rate of leaves will increase sharply. And this is also a critical period for Chinese cabbage to form big leaf balls, so the demand for water and fertilizer will greatly increase. However, under normal planting, this is still a high incidence period of downy mildew in Chinese cabbage. The incidence of downy mildew requires temperature and humidity, so although we can not control the temperature of the open field, we can solve it through humidity.

Therefore, in the rosette period, it is necessary to appropriately reduce the amount of water, so that the soil can be dry and wet. However, in the middle of the rosette period, a flood can be properly watered, and then a deep ploughing can be carried out, which is the last intertillage of Chinese cabbage during the whole growth period. Then control the amount of water to promote cabbage squatting seedlings for about half a month. Ammonium sulfate was the main topdressing fertilizer in rosette stage, and topdressing was about 15-20kg per mu. Farm manure of about 1000kg can also be applied per mu. When topdressing, it is best to bury the fertilizer and try not to apply it on the surface to improve the fertilizer efficiency.

The above is a brief introduction to the fertilizer and water management technology of Chinese cabbage. The method of fertilizer and water management should be adjusted reasonably according to the growth stage of Chinese cabbage to ensure the normal growth of Chinese cabbage. That's all for today's introduction. This article is for reference only. I hope it can help you all.
