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。
Soil microbial biomass C and peanut production under different film mulching stages were studied under the conditions of wind and sand and semi-arid area (Daping apical || peanut || Daping apricot) under the condition of “Fuhua 12” Impact. The results showed that the order of soil microbial biomass carbon in different peanut was: treatment Ⅱ> treatment Ⅰ> treatment Ⅲ> treatment Ⅳ (CK). The effects of different mulching stages on the yield and WUE of peanut reached a significant level. The order of yield and WUE were as follows: treatment Ⅱ> treatment Ⅲ> treatment Ⅰ> treatment Ⅳ (CK). Therefore, the treatment Ⅱ more suitable for the region.
