JD37 Compound microbial fertilizer was mainly made up of wormcast and one plant growth-promoting rhizobacteria strain JD37 screened by microbiology laboratory,which showed significant increase in growth of pakchoi and water pot experiment test,pakchoi fresh weight increased 45.6% and water spinach fresh weight increased 45% compared with control greenhouse cultivation test,pakchoi yield increased 18.2% and water spinach yield increased 107.4% compared with control group.The vegetable quality detection results showed that there was on significant difference between the content of ascorbic acid in both chemical fertilizer and compound microbial fertilizer group,soluble protein content increased significantly in compound microbial fertilizer group.The value of nitrite content in compound microbial fertilizer group was only half of chemical fertilizer group.The experiment results suggested that JD37 compound microbial fertilizer could reduce the nitrite content of vegetables simultaneously.The study lay a soild foundation for the further application of JD37 compound microbial fertilizer.
