在2013年7～8月鲁西地区连降大雨条件下，对大田环境下不同玉米品种设置雨后及时排水（处理A）和不排水（处理B）两个处理，调查其生理生态特征和经济性状。结果表明：玉米生育期受渍害胁迫而推迟，处理B中各品种的产量、穗粒重、植株干物质、株高、穗位、基部茎粗、叶面积指数等均低于处理A，而节根层数、节根条数则有所增加，不同品种对渍害胁迫的响应程度亦有所不同。

During July and August in 2013 , there were continuous heavy rains in Luxi area .Under this condition , the experiments were conducted in field through setting two treatments , drainage in time ( treatment A) and non-drainage (treatment B) after rain, to study the physiological and ecological characteristics and economic characters of different maize varieties .The results showed that the maize growth period was post-poned by waterlogged stress .The characters such as yield , grain weight per ear , dry matter , plant height , ear height, basal-stem diameter and LAI of different varieties in treatment B were lower than those in treatment A, while the layers and number of nodal -roots were higher .Different variety had different response to water-logged stress .
