In general, fertilization is an essential part of a crop that grows well and grows. Recently, some netizens are asking about the fertilization skills of Chinese cabbage. The growers who grow Chinese cabbage know that the growth cycle of Chinese cabbage is long. Fertilization generally applies base fertilizer and top dressing according to the growth characteristics of their own cabbage. Let's take a closer look.
Base fertilizer
Whether the base fertilizer is sufficient determines the high and low yield of Chinese cabbage. The base fertilizer is mainly based on decomposed farmyard manure, supplemented by urea. The farmland requires about 2700kg of organic fertilizer, 5kg of urea, 15kg of diammonium phosphate and 7kg of potassium sulfate.
2. Top dressing
(1) Rose period
After the rosette period of Chinese cabbage today, it enters the rapid growth stage. At this time, sufficient water and fertilizer are needed to ensure the vigorous growth of the cabbage rosette. This period is the key period for determining the yield. The water and fertilizer will increase the yield of Chinese cabbage, and the water and fertilizer will be insufficient. Production will also drop accordingly. Therefore, at this time, 7 kg of urea and 5 kg of potassium sulfate can be applied per acre, and watering can be used to meet the needs of the growth of Chinese cabbage.
(2) Balling period
In the early stage of the ball, the outer leaves of the cabbage grow rapidly. At this time, the nitrogen fertilizer is required to be high. The urea can be applied 10 kg per acre and 7 kg of potassium sulfate to make the outer leaves of the cabbage grow rapidly. After entering the middle of the ball, the leaves inside the cabbage will grow up rapidly. At this time, it is a key period for enriching the interior of the cabbage. It can apply 7kg of urea per acre and 5kg of potassium sulfate to enrich the inner leaves of the cabbage while delaying the senescence rate of the outer leaves of the cabbage. Therefore, the nutrients for photosynthesis are continuously provided for the interior of cabbage.
3. Root dressing
In addition to the application of base fertilizer and top dressing, the Chinese cabbage can also reduce the incidence of heartburn and improve the vegetable yield of Chinese cabbage through the method of root dressing. At the same time improve the quality and yield of cabbage.
The above is the fertilization technique of Chinese cabbage. Let's see what else needs to be added. Would you like to know more about Chinese cabbage? Continue to pay attention to Hui Nong Internet!
