@@@@在田间试验条件下研究施用沼液对大白菜产量和品质的影响，探讨施用沼液替代化肥的农学效果。结果发现，施用沼液可明显增加大白菜的产量；由大白菜产量和沼液用量线性模拟计算得知，投入2.9倍氮的沼液用量时，可以达到化肥处理的大白菜产量。施用沼液可提高大白菜硝酸盐含量，对提高大白菜中可溶性固形物有显著作用。与化肥处理相比，沼液处理的大白菜Vc含量较高，但差异不显著。

As the biogas slurry having the advantages of multiple nutrient and stable supply, a field experiment was carried out to study the effect of biogas slurry on the yield and quality of Chinese cabbage. The results indicated that the yield of Chinese cabbage in the treatments of biogas slurry was significantly increased. It was necessary to apply biogas slurry equivalent to 2.9 times of chemical nitrogen to obtain the same yield of Chinese cabbage in the treatment of chemical fertilizer according to the linear relationship between the yield of Chinese cabbage and dosage of biogas slurry. The soil nitrate content was increased after applying biogas slurry, so that the dosage of biogas slurry should be controlled in future experiments. The soluble solid content was significantly increased, and the Vc content was higher in comparison with the treatment of chemical fertilizer with no significant difference.
