摘    要:研究了在高产条件下,不同行距配置、密度对兰考906群体结构、光合及产量的影响。结果表明,16.7cm的行距配置由于冬前分茶蘖多,春季分蘖少,减缓了营养生长与生殖生长的矛盾,成穗数、穗粒数较多。;23.3cm行距配置无效分蘖多,后期群体较小,功能叶衰老慢,粒重高;密度增加,产量并未提高。16.7cm行距配置375万/hm^2基因苗处理产量最高。

关 键 词:小麦  行距配置  密度  群体结构  产量

Abstract:Effects of different spacing form、density on structure of population、photosynthesis and grain yield of Lankao906 were studied under the high-yielding condition. The results showed that spacing form of 16.7 cm had little contradiction of vegetative growth and reproductive growth and higher tiller-survival per area than others.The spacing form of 23.3 cm had higher grain weight resulted from slowly-senescing leaves. The grain yield of spacing form of 16.7 cm and 375×104 basic seedlings per hectare was the highest.
Keywords:Wheat  Spacing form  Density  Structure of population  Grain yield
