Before and after the beginning of autumn, it is a good time to grow cabbage, and cabbage wants high quality and high yield. In addition to selecting the planting time, it is necessary to do fertilization work. As the saying goes, the crops are full of flowers, and they all depend on the fat. Therefore, the length of cabbage is good, and it has a great relationship with fertilizer. The following Hui Nongwang Xiaobian will talk to you about the key points of cabbage fertilization.
Cabbage grows fast and requires a lot of fertilizer. Therefore, when planting cabbage, in addition to the essential base fertilizer, it is necessary to topdress according to the different stages of cabbage growth.
The base fertilizer for planting cabbage is generally based on fully decomposed farmyard manure, supplemented by chemical fertilizer. Before the land preparation, the farmer's fertilizer is evenly sprinkled, and then the farmer's fertilizer is turned to the bottom of the soil by deep turning, which is beneficial to the nutrients of the cabbage roots. When using farmyard manure as the base fertilizer, the farmyard manure must be fully decomposed, because in the process of decomposing, the ammonium nitrogen in the fertilizer can be converted into nitric acid which can be absorbed by the cabbage, and the bacteria and eggs remaining in the fertilizer can be killed.
After the seedlings in the cabbage, the amount of quick-acting fertilizer can be applied in an appropriate amount to ensure that the cabbage seedlings have sufficient nutrients during the growth process. When the cabbage enters the rosette stage, it is topdressed and watered. The sufficient water and nutrients can make the cabbage leaves produce more photosynthesis products, which provide powerful conditions for the growth of the cabbage after the rosette period. After the cabbage enters the ball-forming period, the potassium fertilizer is applied. At this time, the cabbage needs more water to increase the amount of fertilizer. The sufficient water and fertilizer can enrich the inside of the cabbage leaf ball, so that the grown cabbage is more solid, and the cabbage is full enough to increase the whole cabbage. Weight, thereby increasing the variety and yield of cabbage.
During the growth of Chinese cabbage, the most potassium is absorbed. The sufficient potassium can promote the light and effect of the leaves, and ensure the filling of the leaves. If the potassium is insufficient, the leaves will turn yellow and dry, and in severe cases, the cabbage will be development of. So whether it is in the application of fertilizer or in topdressing, you must not ignore the presence of potassium.
The above is the explanation of the key points of the cultivation of fertilization of cabbage after the fall of the Hui Nong Network. Do you understand? Fertilization is still an important agricultural step for the high yield of cabbage. Farmers must apply fertilizer and grow good food!
