Influences of Combined Application of Water-soluble Organic Fertilizer and Inorganic Fertilizer on Yield,Nutrient Absorption and Economic Benefit of Cabbage

The influences of combined application of water-soluble organic fertilizer and inorganic fertilizer on the yield,nutrient absorption and economic benefit of cabbage were studied.The results revealed that:as compared with the single application of inorganic fertilizer,the application of water-soluble organic fertilizer in the manner of root-irrigation combined with inorganic fertilizer could significantly enhance the package rate,package weight,yield and economic benefit of cabbage,as well as the contents of chlorophyll,phosphorus and potassium in cabbage leaf,and could increase the accumulation and utilization efficiency of nitrogen,phosphorus and potassium in cabbage to a certain degree.The combined application of water-soluble organic fertilizer and inorganic fertilizer in the manner of root-irrigation obtained better comprehensive effect than that in the manner of foliage spray.
