摘要
在风沙半干旱区间作(大扁杏||花生||大扁杏)条件下,以花生品种"阜花12号"为材料,研究了不同覆膜时期对土壤微生物量碳与花生产量的影响。结果表明:不同覆膜时期花生土壤微生物量碳含量顺序为:处理Ⅱ>处理Ⅰ>处理Ⅲ>处理Ⅳ(CK)。不同覆膜时期对花生产量、WUE的影响达到显著水平,产量与WUE的高低顺序均为:处理Ⅱ>处理Ⅲ>处理Ⅰ>处理Ⅳ(CK)。因此,处理Ⅱ较适宜本地区。
We had an experiment on the prunus armeniaca intercropping peanut Fuhua 12; and we studied effect of different plastic film mulch period on microbial biomass carbon of soil and peanut yield in the sandy and windy semi-drought area. The results showed： The microbial biomass carbon of different plastic film mulch period were： II 〉I〉 III 〉IV （CK）. The effect of different plastic film mulch period on peanut yield and WUE were significant, and the number of yield and WUE were II 〉 m〉I〉IV（CK）. So the treamentII was better for the sandy and windy semi-drought area.
