摘　　要：研究两个玉米品种春播、复播条件下的生长表现,结果表明:与春播相比,玉米夏播苗期阶段缩幅较大,达13天,穗期阶段基本不变,花粒期阶段有所延长5天,株高增加31~55 cm,穗位增加20~25.8 cm;不同玉米品种在不同季节栽培时,产量表现不同,栽培优势也不同。新玉7号夏播、鲁丰1号春播产量较高,分别达1 538.8 kg/667m^2和1 340.9 kg/667m^2,生产中应根据时令选用品种。The growth performance of two maize varieties of Xinyu 7 and Lufeng 1 in spring and summer sowing conditions was studied,the results showed that： Compared with spring sowing,the seedling stages of summer sowing maize were greatly shortened about 13 days,little changed ear stages,and about 5 days prolonged flower stages,the plant height and ear height increased about 31 ~ 55 cm and 20 ~ 25. 8 cm respectively; The yields of different maize varieties differed in different sowing seasons. The yield of Xinyu 7 was higher when sowing in summer whereas Lufeng 1 was higher when sowed in spring,with the yield of 1 538. 8 kg/667 m^2 and 1 340. 9 kg/667 m^2 respectively.
