| 摘 要： | 2008-2009年在黄河流域棉区,采用池栽方法研究了3种土壤质地对棉花成铃时空分布及产量的效应.结果表明,土壤质地对棉花成铃时空分布和产量有一定影响.与黏土和壤土相比,棉花种植在沙土上,尽管在中下部果枝上的成铃数较少,但占总铃数的比例较高；在果枝内围果节上的成铃数较少,但占总铃数的比例也较高；伏前桃和伏桃占总桃数的比...

| Abstract: | Pool-culture experiment was conducted to study the effects of soil texture(clay,loam,sandy) on spatial-temporal distribution characteristics of bolls and yield of cotton in 2008 and 2009.The results showed the soil texture had some effect on spatial-temporal distribution of bolls and yield of cotton and the number of bolls setting on the fruit branches of the mid-lower part and the inner fruit nodes of cotton were the lowest,but the ratio of that to the number of total bolls were the highest in the sandy so... |
