摘　　要：为探索绿旱1号的节水特性,比较了绿旱1号及原始受体＂6527＂在有水层管理和无水层旱管条件下的生育期和经济性状。结果表明,在无水层较有水层节水67.4%的条件下,2个品种生育期均延长2~5天。在无水层旱管方式下,＂绿旱1号＂千粒重、结实率、株高、有效穗降幅较小,但均未达显著水平,而原受体＂6527＂小区产量、穗总粒数、理论产量、穗实粒数降幅最大,均超过25%,且均达极显著水平（P〈0.01）。＂绿旱1号＂在节水栽培条件下,表现产量稳定、节约能源、减少环境污染等优点。Studies on the water-saving of ‘ LvhanNo.1 ’.Growth period and economic characters of all-water layer supply and non-water layer supply were compared.It indicated that the growth periods of ‘ Lvhan No.1 ’ and 6527 all lengthen 2 to 5 days by non-water layer,which saving 67.4% water compared by all-water layer.‘ Lvhan No.1 ’ decreasing range was not remarkable,which concluded of the 1000-grain weight,seed setting rate,plant height and effective panicles.However,plot yield,the grain number per panicle,the theoretical yield,the filled grain number per panicle of 6527 decreased range was larger and reached a very significant level （P0.01）,which range decreased by over 25%.When ‘ Lvhan No.1 ’ was cultivated by save-water,it can maintain stable yield and save energy and reducing pollution and so on.
