摘　　要：芸豆种植中,覆膜不仅能增温保墒、还能增产增效,为探索不同覆盖物对芸豆生长保墒效果的影响。本研究以冀张芸2号红芸豆为材料,采用不覆膜、黑膜、白膜、全生物降解渗水地膜、黑膜膜下滴灌等5种不同覆盖物为处理,研究芸豆生产中的保墒效果。结果表明,芸豆全生育期降水量194.8 mm,耗水量在254.9~318.8 mm之间。渗水膜耗水量最低,为254.9 mm;膜下滴灌耗水量最高,为318.8 mm。黑膜与白膜处理的耗水量分别为263.0 mm与269.7 mm;不覆膜处理耗水量299.9 mm。芸豆收益以膜下滴灌最高,为11 559.8元/hm^(2),不覆膜收益最低,为6 996.0元/hm^(2)。白膜水分利用效率最高,为7.59 kg/(hm^(2)·mm);不覆膜水分利用率最低,为5.99 kg/(hm^(2)·mm)。For kidney bean production,mulching film can not only increase temperature and conserve soil moisture,but also increase yield and efficiency.The study explored the effects of different mulches on the soil moisture of kidney bean,the soil moisture conservation of Jizhangyun No.2 red kidney bean was studied by using five different mulching film treatments(non-mulch,black film,white film,full biodegradable water permeable mulch and drip irrigation under black film).The results showed that the precipitation during the whole growth period of kidney bean was 194.8 mm,the water consumption was between 254.9-318.8 mm.The water consumption of permeable film treatment was the lowest with 254.9 mm,which of the drip irrigation treatment was the highest with 318.8 mm,the black film treatment and the white film treatment respectively was 263.0 mm and 269.7 mm,the non-mulch was 299.9 mm.The economic benefit of the drip irrigation treatment was the highest with 11559.8 yuan/hm^(2),which of the non-mulch treatment was the lowest with 6996.0 yuan/hm^(2).The WUE of the white film treatment was the highest with 7.59 kg/(hm^(2)·mm)and which of the non-mulch treatment was the lowest with 5.99 kg/(hm^(2)·mm).
