摘　　要：施用沼液对白菜产量、品质和养分吸收的影响试验结果表明,施用沼液能够显著提高白菜的产量,与化肥处理相比增加了白菜游离氨基酸的含量,提高硝酸还原酶活性,降低硝酸盐含量,改善白菜品质;与对照相比,施用沼液提高了白菜N含量和N、P、K、Ca的养分累积量,但是沼液用量过高也会降低养分农学利用率。The effect of slurry on the yield, quality, and nutrition absorption of Chinese cabbage was determined. Results showed that the yield of Chinese cabbage was enhanced significantly when slurry applied. Compared to the chemical fertilizer treatment, the content of free amino acid increased, and the content of nitrate decreased for the activity of nitrate reductase enhanced. The content of N and the accumulation of N,P, K,Ca increased compared to the control. However, the agronomic nutrition use efficiency would decline with slurry application increasing.
