Cabbage needs fertilizer properties

Cabbage takes the leaves as a product organ, and sufficient supply of nitrogen can increase the chlorophyll content and increase the intensity of photosynthesis. Dark green leaves are thick and are conducive to the expansion of the outer leaves and the enrichment of leafballs. In the absence of nitrogen, the leaves gradually yellow and dry from the outside to the inside. When nitrogen is in excess, the leaves are large and thin, and the ball is not tight, and the flavor quality, disease resistance, and storage are decreased.

Phosphorus can promote cell division and differentiation of leaf primordium, accelerate the formation of leaf ball, and promote the growth and development of root system. In the absence of phosphorus, the plants are short, the leaves are dark green, and the bulbs are slow.

Potassium can enhance photosynthesis and promote the production and transport of organic matter in leaves. The supply of potash fertilizer is sufficient, which can enrich the leaf ball and increase the yield; when the potassium is lacking, the edge of the outer leaf blade appears dry ribbon, and when it is severe, it can develop towards the heart blade.

Cabbage is a calcium-bearing crop, the outer leaf calcium content is as high as 5% to 6%, while the heart leaf calcium content is 0.4% to 0.8%. When the environment is bad and the management is not good, cabbage will produce physiological calcium deficiency and dry heart disease, which has a great impact on quality.
