Cabbage Fertilizer for Chinese Cabbage

Cabbage grows for a long period of time, accounting for about half of the entire growth period, and has a large amount of growth. The accumulation of matter in the ball-making period accounts for two-thirds of the total weight. It is the period when the fertilizer is needed most. Grasping the management of fertilizer and water during the ball-bearing stage of Chinese cabbage is the key to ensuring the high yield and quality of Chinese cabbage.

The top-dressing Chinese Cabbage usually chases 2~3 times of fat. The first time in the early stage of ball-bearing, combined with irrigation and top-dressing a heavy fertilizer, it is called “suction tube fertilizer”, and the application of ammonium sulfate or urea 10~15 kg per mu, or about 1500 kg of thin manure water in combination with irrigation, can also be chased. Cake fat 50 ~ 100 kg, but the cake must be fermented maturity. At the same time, 7.5 to 10 kg of superphosphate and potassium sulfate should also be applied to promote leaf ball growth. In the middle of the ball, combine irrigation with a “heart filling manure”, apply 10-15 kg of ammonium sulfate or 1000-1500 kg of human waste per acre, and promote the compaction of the bagasse. Deep digging. In the late ball stage, 10 kg of ammonium sulphate or 1,000 kg of human waste was applied. The topdressing should not be too heavy in the later period to prevent the burnt root from affecting the growth of the leafball.

Watering Chinese cabbage needs the most water after it enters the ball stage. Therefore, just after the end of the seedling, it will be poured with water, and then the second water will be poured every 2 to 3 days. This time it is very important. If the soil is cracked, Will cause lateral root fracture, fine roots dead, affecting the ball. Afterwards, water is usually poured 5 to 6 days to keep the soil moist. Irrigation should adopt furrow irrigation method, so that the water slowly infiltrate, so that it can not only ensure the water needed for the growth of cabbage, but also avoid the excessive water and promote the occurrence of soft rot. Irrigation should be done so that no water accumulates in the ditch, no water is present on the ridge (raft), and there is no water shortage in the root system. In the late stage of ball-bearing, watering should be appropriately reduced to improve the quality and enhance the storage stability. Watering should be stopped 7-8 days before harvest to avoid excessive water storage in the leaves.
