S531; [目的]为山东日照地区甘薯种植提供技术支持.[方法]采用田间小区试验,设置3种颜色地膜处理:黑色膜(BM)、透明膜(TM)和不覆膜(NM),以及3种滴灌湿润比处理:不灌溉(P0)、30％湿润比(P1)、60％湿润比(P2),共9个处理,探究了不同颜色地膜和滴灌湿润比对土壤温度、土壤含水率以及甘薯生长发育和产量品质的影响.[结果]在相同湿润比条件下,覆膜处理可以显著提高甘薯生育前期土壤温度,到生育后期,覆膜和不覆膜之间差异变小;而在相同覆膜条件下,不同湿润比的土壤温度相差不大.在典型天(阴天),P2处理的土壤温度变化幅度小于P1处理和P0处理的.在生育前期TM处理较BM处理和NM处理可以增加表层土壤含水率,覆膜在多雨季节可以增加地表径流,降低土壤含水率;在相同覆膜条件下,不同湿润比...
