摘    要:
研究了苗期(4叶期)、拔节期和灌浆期的白马牙玉米每层叶鲜重与单地上生物量(鲜重或干重的)回归方程。结果表明,按人上至下的顺序排叶序,则苗期的第2-3层叶、拔节期的第4层叶和灌浆期的第4-6层叶的叶鲜民相应生育时期的单株地上生物量呈极显著的正相关,可分别用以快速估测该生育时期的单地上生物量。

关 键 词:玉米 青贮玉米 叶鲜重 地上生物量

Abstract:
The linear regression equations of leaf fresh weight and single plant aboveground biomass of Zea mays in seedling, jointing and filling stages were studied. The results showed that if the leaf sequence were arranged from up to down, the leaf fresh weight of the second to third layer of leaves in seedling stage, the forth layer in jointing stage and the forth to sixth layers in filling stage had a extremely significant positive correlation with single plant aboveground biomass in the same time reproductive stage, respectively; and they could be used to rapidly estimate single plant aboveground biomass in its same time reproductive stage.
Keywords:Zea mays   leaf fresh weight   estimating   aboveground biomass
