Abstract

Abstract: [Objective][Method]Conventional fertilization was used as control. Effects of biogas slurry application on soil microbial biomass, enzyme activity and nutrient content before and after harvest in broccoli were studied. [Result] Results showed that the number of bacteria and actinomycetes under biogas slurry application were significantly greater than those of conventional fertilization before broccoli planting, the differences were 91.16% and 79.09%, respectively. While the number of fungi under biogas slurry application lower than those of conventional fertilization before broccoli planting, the differences were55.03%. The soil urease activity and invertase activity under biogas slurry application lower than those of conventional fertilization before broccoli planting, the differences were 27.01% and 15.58%, respectively. The soil urease activity and invertase activity under biogas slurry application greater than those of conventional fertilization at broccoli harvest, the differences were 13.18% and 11.50%, respectively. The soil organic matter contents under biogas slurry application greater than those of conventional fertilization before broccoli planting and at broccoli harvest, the differences were 79.61% and 29.46%, respectively. [Conclusion] In conclusion, biogas slurry application can increase the quantity of soil bacteria and soil actinomycetes before broccoli planting. Biogas slurry application can improve soil urease and invertase activity, and soil nutrient content at broccoli harvest.
