摘　　要：选择甘肃省河西走廊淡漠土区连续种植制种玉米12a的试验地,采用田间试验方法,研究了生物活性肥配方的筛选及其对土壤理化性质和玉米经济效益的影响。结果表明,生物活性肥配方最佳组合为:功能性改土剂0.12t,生物菌肥0.09t,多元复混肥1.20t。生物活性肥施用量与土壤总孔隙度、团聚体、持水量、玉米植物学性状、经济性状和产量呈显著的正相关关系,与土壤容重、pH值呈显著的负相关关系。经回归统计分析,生物活性肥施用量与玉米产量间的肥料效应可用二次函数拟合,经济效益最佳施用量为1.80t/hm2,玉米的理论产量为6 597.24kg/hm2。The formula of bioactive fertilizer and its effects on the physical and chemical properties of soil and economic benefits of maize was studied using field test in the Hexi Corridor light irrigation desert soil of Gan- su Province. The results showed that the optimum proportion of biological active fertilizer was as follows. functional improving soil agent was 0.12 tons, bacterial manure was 0.09 tons, and biological active fertilizer was 1.20 tons. There was a positive correlation between fertilization quantity and soil porosity, aggregate structure, water contents, saturated water content, botanical traits, the economic characters and yields of maize. In addition, There was a negative correlatation between fertilization quantity and bulk density, pH value. According to regression analysis, the optimal economical application rate was 1. 8 t/hm2, and the theoretical yield was 6 597.24 kg/hm2.
