There are tricks for increasing production and topdressing of Chinese cabbage: topdressing skills of Chinese cabbage

Chinese cabbage is a very common vegetable. Chinese cabbage is grown in almost every field in the countryside. Topdressing is the key to increase yield, so what are the topdressing skills of Chinese cabbage?

First, spread fertilizer

Generally speaking, after the Chinese cabbage field has just been watered or rained, the soil condition is suitable, and chemical fertilizer can be applied in the field or between the rows of plants. This method of fertilization is simple, but some of the fertilizers will volatilize and lose their effect. Volatile fertilizers are not suitable for this method of fertilization. But urea can be fertilized by sprinkling, but it needs to be used when the leaves of Chinese cabbage are not scattered all over the ground.

Second, flushing and applying

Flushing is to mix the fertilizer in the water, and then pour it on the cabbage, allowing them to seep into the soil with the water to nourish the roots of the cabbage. The advantage of this method is simple and convenient, time-saving and labor-saving. The disadvantage is that this method wastes a lot of fertilizer, which may not reach the deep layer of the soil and can not play a corresponding role. However, if there is a large area of lack of fertilizer in Chinese cabbage and the situation is urgent, this method can be used as the first choice.

III. Burying and giving

Burying fertilizer is generally in the middle and later stage of the growth of Chinese cabbage, it is necessary to dig a hole between the rows of the plant to bury an appropriate amount of chemical fertilizer, and then bury it. Special attention should be paid to fertilization, not too close to the root of Chinese cabbage, so as not to damage the root and play a negative role. The safe distance is generally more than 10 centimeters. After the completion of burying fertilizer, it is necessary to water in time to reduce the fertilizer concentration and improve the fertilizer efficiency.

Fourth, foliar fertilizer spraying

It is a simple and effective method to apply fertilizer with less amount of foliar fertilizer and fast fertilizer effect. It can also be combined with pest control for prickle foliar spraying. In addition to several common fertilizers, this method can also choose fertilizers that contain a large number of elements and various amino acids. However, this method can only be used as an assistant. The main source of nutrients for the growth of Chinese cabbage is base fertilizer and other topdressing.

5. Facility topdressing

Facility topdressing has drip irrigation and topdressing, which is a new technology. Specific operation: install the Venturi fertilizer applicator at the main part of the drip irrigation facility where the water source enters the drip irrigation facility, dissolve the chemical fertilizer with a container, insert it into the suction tube filter of the Venturi fertilizer applicator, and the fertilizer can automatically enter the soil around the crop root system with watering. In this way, the effect of fertilizer is maximized and the concentration is small, so it is safer.

There are many people who grow Chinese cabbage, but the output is different, which may be caused by improper topdressing methods. The above five tips hope to help novice vegetable farmers grow Chinese cabbage.
