摘要: Abstract Bio-fertilizers are thought to be overwhelmingly superior chemical fertilizers for the improvement of soil quality and productivity. However, comprehensive effects bio-fertilizer on ecosystem possibility using multiple beneficial biota still not well understood. A two-year field study was conducted examine how crop yield, biochemical properties, enzyme activities, functional diversity responded different bio-fertilizers in sweet potato phase a double-cropping system (sweet rapeseed). Six fertilizer treatments, including one treatment (CF), two organic treatments (OM, manure; MC, manure plus fertilizer) three (MCN containing nematodes, MCE earthworms, MCP phosphate-solubilizing bacteria) were compared. The soils under CF had lowest values all parameters comparison with other treatments. Among OM performed better improving biological properties such as respiration microbial biomass, while these similar activities functionality. Crop yield positively correlated nutrient levels, biomass activity, most variables highly intercorrelated. Our results indicated that generally improved productivity levels field.
