摘　　要：2007年在黑龙江省甘南县进行了行间覆膜对玉米根系层土壤水分动态及玉米产量影响的试验研究,在玉米全生育期,采用时域反射仪(TDR)对土壤水分指标进行观测,分析了玉米全生育期农田土壤水分动态变化过程。在收获后对玉米进行测产分析。结果表明:行间覆膜与常规耕作比较,有效地提高了土壤含水量,具有较好的节水作用;玉米增产效果明显。A research about the effects of covering film between furrows on dynamic of soil moisture in root zone and yield of maize was developed in Gannan country, Heilongjiang Province in 2007. We made observations about the soil moisture index and yield of maize during whole growth period, and analyzed the dynamic change of soil moisture in farmland by Time Domain Reflectometry（TDR）. The results indicate that covering film between furrows can effectively increase soil water content and have fine function of watersaving, and the yield of maize increase obviously.
