Fertilizing method for reducing weight, improving efficiency, improving quality and increasing yield of cabbage

The invention provides a fertilizer application method for reducing weight, improving efficiency, improving quality and increasing yield of cabbage, and belongs to the technical field of crop nutrition and fertilizer application. The cabbage fertilization method comprises the following steps: calculating the fertilizer demand of the cabbage in the growth period according to the target yield, testing soil and carrying out formulated fertilization, and carrying out combined application of organic fertilizer and inorganic fertilizer. Applying 30% of an organic fertilizer nitrogen source and 70% of an inorganic fertilizer nitrogen source by taking the total nitrogen amount as a standard; inorganic fertilizer phosphorus and potassium sources are supplemented based on the application amount of the organic fertilizer phosphorus and potassium sources to meet the fertilizer requirement of the cabbage in the growth period. According to the fertilizing method, the content of nitrogen, phosphorus and potassium in the cab
