Abstract

ABSTRACT Plastic mulching is considered as a simple, yet effective land management measure to modify microclimate in semi-arid areas. However, the influence of plastic mulching on local soil nematodes and soil quality needs to be investigated more deeply. To fill the knowledge gap, we compared the characteristics of soil nematode communities (density, trophic structure), soil enzyme activities, soil physicochemical properties, and their relationships between maize fields cultivated with use of plastic film mulching and no film mulching, under the same land conditions in Chifeng region, Inner Mongolia. The results showed that the total number of nematodes in most of the film mulched (FM) fields was lower than in no film mulched (nFM) fields. Most of soil chemical properties showed no significant difference between nFM samples and FM samples. Only 0–10 cm soil layer in nFM samples had significantly higher urease activity than in FM samples in June. Plastic film mulching may have an adverse effect on soil quality. Thus, the correct and effective use of plastic film mulch is one of the important measures for future agricultural development in semiarid areas.
地膜覆盖对半干旱区玉米不同生育期土壤线虫和土壤质量的影响
地膜覆盖被认为是半干旱区一种简单而有效的土地管理措施。然而,地膜覆盖对当地土壤线虫和土壤质量的影响有待进一步深入研究。为了填补这方面的知识空白,本研究比较了在相同土地条件下,内蒙古赤峰地区覆膜和不覆膜玉米田土壤线虫群落(密度、营养结构)、土壤酶活性、土壤理化性质的特征及其相互关系。结果表明:大部分地膜地线虫总数低于未地膜地;土壤的大部分化学性质在nFM和FM样品之间没有显著差异。6月份,土壤中0 ~ 10 cm土层脲酶活性显著高于土壤基质。地膜覆盖可能对土壤质量产生不利影响。因此,正确有效地利用地膜覆盖是未来半干旱区农业发展的重要措施之一。
