摘　　要：为推广节水抗旱稻以提高水稻的水分利用效率,2008-2009年在上海市奉贤区庄行镇对节水抗旱稻"旱优3号"进行5种栽培方式的试验,并对其产量和经济效益进行了分析。结果表明:机插秧栽培方式产量最高;免耕栽培方式经济效益最好,并能改善土壤理化性质;传统栽培方式生产投入最大,收益最低。In order to extend the area of water-saving and drought-resistant rice（WDR） and thus improve water use efficiency of rice,field experiments with the WDR variety＂Hanyou 3＂were carried out under 5 kinds of cultural practices at Zhuanghang,Fengxian during 2008 - 2009.The results showed that mechanized transplanting got the highest rice yield,no-tillage culture gained the best economic benefit and improved soil physical and chemical properties,and traditional cultural practice was the highest in input but the lowest in income.
