摘    要:1996 ̄1997年的超高产夏玉米栽培试验研究表明,超高产夏玉米的最大叶面积指数可达5.7左右,叶片的功能期长,叶面积4.0以上的时间在60d以上,总光合势大,净同化率高。营养器官干物质积累的高峰期在吐丝后30d前后,吐丝前后的干物质积累比例约为4:6,经济系数在44%左右,研究还发现,黄淮海地区玉米生长季节的天气条件尤其是日照时间是影响玉米产量的重要因素。

关 键 词:夏玉米  超高产  生育特点

Abstract:In 1996-1997 field experiments were conducted to study the growth mechanism of super-high yield summer maize in Wenxian County,Henan Province.The resutls indicated that LAI,LAD and NAR of supper-high yield summer maize were higher than those of the normal,the DM accumulation of nutrition organ was the highest about 30 d after silking.It was also found that the yield of summer maize was mainly affect by the climate conditions especially the sunshine time,during growing season.
Keywords:summer  maize  super-high  yield  character  of  growth  and  development
