Autumn Chinese Cabbage Knot Fertilizer Can Increase Yield

After the Lunar New Year, the weather gradually cooled and the autumn cabbage entered the ball stage. Chinese cabbage needs about 50% of the total growth period in the period of the ball-bearing period. If defertilization occurs during the ball-balling period, it will directly affect the tightness of the core and reduce the yield and quality. This stage is the stage of re-applying the period of recovery. Generally, 20 mu of urea will be applied with water, and top dressing will be about 10 days. Usually, it takes 2-3 consecutive times for topdressing. In the later stage of the ball, due to shorter light, lower temperature, slower plant growth, aging of the root system, and poor function of nutrient absorption, the effect of top dressing is no longer obvious. At this time, top dressing is not suitable. It can spray foliar fertilizer such as potassium dihydrogen phosphate, urea or green leaf treasure, which can significantly increase the yield of autumn cabbage and improve quality.
