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10号"为材料,研究了不同秸秆还田量对花生土壤酶活性和产量的影响。结果表明:秸秆覆盖还田能显著提高土壤脲酶、过氧化氢酶、蛋白酶的活性,处理Ⅲ的土壤脲酶与蛋白酶活性较强,处理Ⅱ过氧化氢酶活性略高于处理I与处理Ⅲ。秸秆覆盖还田对花生产量和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 studied the effect of straw returning amount on the yield of peanut variety Fuhua10 and soil enzyme activity under intercropping system（prunus armeniaca-peanut-prunus armeniaca） in the sandy and windy semi-drought area.The results showed： The activity of urease,catalase and protease were increased significantly through straw returning.The urease and protease of treatment Ⅲ were stronger than other treatments,and the catalase activity of Ⅱ was higher than that of Ⅰ and Ⅲ.The effect of straw returning on peanut yield and WUE was at significant difference level.The peanut yield and WUE of different treat were ⅡⅢⅠⅣ（CK）.So treat Ⅱwas more suitable to the local area.
