Fertilization skills of Chinese cabbage in autumn!

There are still a lot of cabbage growers in autumn, but the quality of cabbage varies greatly from household to house. the reason for these phenomena is actually caused by our wrong fertilization methods. Here are some techniques for fertilizing Chinese cabbage in autumn!

First, Sashi

After watering or raining in the early stage of Chinese cabbage, when the soil moisture of the border is suitable and can go down to the field, the quantitative chemical fertilizer is applied to the border or between the plants and rows. This method of fertilization is also relatively simple, but there will be volatilization loss of some fertilizer components. If ammonium bicarbonate is highly volatile, this method can not be used; urea can be spread, but only before the Chinese cabbage is used before the fan is full, the operation is not convenient, and when the cabbage seedling needs fertilizer and is urgent, attention should be paid to chemical fertilizer to avoid leaking into the leaf roll heart.

Second, flushing and applying

When Chinese cabbage is watered, the quantitative chemical fertilizer is sprinkled in the ditch to dissolve and infiltrate into the soil around the root system with the watering. This method wastes a lot of fertilizer, which is easy to leak and lose in the channel, can not reach the deep layer of the root system, and will infiltrate part of the fertilizer. The utility model has the advantages of simple use, labor and time saving and less labor. When severe fertilizer deficiency occurs in a large area, it can be used as the first choice for topdressing.

III. Burying and giving

In the middle and later stage of the growth of Chinese cabbage, trenches and holes were opened between plants and rows, quantitative chemical fertilizer was applied, and then filled with soil. Pay attention to safety when applying. The buried manure pit should be more than 10 cm away from the main root of Chinese cabbage. If it is too close to the root, it is easy to damage the root system. In order to prevent the negative effect, the fertilizer concentration must be reduced and the fertilizer efficiency should be improved by watering in time after burying and applying.

Fourth, foliar fertilizer spraying

In the management of Chinese cabbage, in addition to paying attention to timely topdressing, foliar fertilizer can be sprayed many times in combination with pest control. This fertilization method has the advantages of low dosage, fast fertilizer effect, and can avoid nutrients being fixed by soil, so it is a labor-saving and effective fertilization method. In addition to urea, potassium dihydrogen phosphate, potassium sulfate, potassium nitrate, compound fertilizer and other commonly used fertilizers, the fertilizers sold in the market containing a large number of elements and various amino acids have a certain effect. However, the nutrients needed for the growth and development of vegetables mainly come from base fertilizer and other topdressing, foliar fertilizer spraying can only be used as an auxiliary fertilization measure.

5. Facility topdressing

In recent years, with the popularization and application of science and technology, the matching drip irrigation technology has been widely used, and the fertilization method is moving towards automation. The specific application method is as follows: when the water source enters the main part of the drip irrigation facility, the Venturi fertilizer applicator is installed, and the chemical fertilizer is dissolved in a container and inserted into the suction tube filter of the Venturi fertilizer applicator. the fertilizer can automatically enter the soil around the crop root system with watering. The fertilizer is not easy to volatilize and has no loss. although the fertilizer is concentrated, the concentration is small, so it is relatively safe, labor-saving and time-saving, and the effect is good. Fertilization by drip irrigation is the most scientific and promising topdressing method at present. Therefore, the topdressing of Chinese cabbage can make use of this scientific and advanced fertilization method.

The above article introduces how to fertilize autumn Chinese cabbage and some simple methods of fertilization for autumn Chinese cabbage. I hope it can help you to better plant autumn Chinese cabbage in the coming autumn.
