摘要: 研究了玉米不同生长发育时期根际土壤酶活性对宽窄行休耕轮作和常规均匀垄2种种植方式的响应。结果表明:宽窄行种植方式下的土壤脲酶、酸性磷酸酶、中性磷酸酶和转化酶活性显著高于均匀垄种植方式,而蛋白酶活性二者差异不显著;不同时期的土壤酶活性也有一定的规律性变化,除土壤脲酶和酸性磷酸酶外,6月27日的土壤酶活性普遍高于8月和10月2个时期。可见玉米宽窄行种植方式具有较高的土壤脲酶、酸性磷酸酶、中性磷酸酶和转化酶活性,更好地为作物生长提供C、N、P的供应。对提高玉米产量具有重要意义。

Abstract: This paper studies the response to two kinds of planting patterns of narrow-wide row fallow crop rotation and conventional uniform row of soil enzyme activities in crop rhizosphere soil at different growth period.The results showed that urease, acid phosphatase, neutral phosphatase and invertase activities of narrow-wide row planting patterns were significantly higher than that of uniform row planting patterns, but the differences in protease activity of these two patterns were not significant.Soil enzyme activities in different period have regular changes.Except urease and acid phosphatase, soil enzyme activities on June 27th are significantly higher than that in August and October.Narrow-wide row planting patterns of maize have higher soil urease, acid phosphatase, neutral phosphatase and invertase activities, which can better provide C, N, P for corn growing.Consequently, further study on the effect of narrow-wide row planting patterns of maize on soil enzyme activities, will instructive in improving the yield of corn.
