| 摘 要： | 采用田间小区试验方法研究了玉米秸秆和根茬留田对土壤生化环境因子的影响。结果表明：玉米秸秆和根茬留田可增加土壤微生物量碳的含量，较对照和单纯化肥土壤微生物量碳分别增加38．4％－84．9％和27．2％＝51．6％；增强土壤pH值的缓冲性能；改善土壤团聚体结构；有利于土壤中氮、磷、钾、铜、锌、铁、锰等养分的释放与调控，为作物生长创造适宜的土壤生化环境。 |
| 关 键 词： | 玉米 植株 残体留田 土壤 环境因子 玉米秸杆 根茬 施肥 土壤肥力 土壤微生物量碳 生化环境 |

| Abstract: | Based on field micro-plot experiment, the effects of corn stalk and stubble remained in field on soil biochemical factors were discussed. The results indicated that corn stalk and stubble rationing application of N fertilizer would increase the content of soil microbial biomass carbon. Soil pH buffer capacity was strengthened. Soil aggregate structure was improved. Corn stalk and stubble remained in field would be helpful to maintenance and liberation of soil available nutrients( N, P, K, Cu, Zn, Fe and Mn) . |
| Keywords: | corn stalk stubble remained in field application of fertilizer soil fertility soil microbial biomass carbon |
