| 摘 要： | 羊草(Leymus chinensis)是根茎性禾草,是东北及内蒙东部地区广泛分布的主要建群种之一。以羊草为建群种的羊草群落分布广、面积大、是优良的天然草场。羊草草场的产草量与植物的地下部特别是根茎中贮藏性物质的含量有密切关系。因为多年生根茎性植物所制造的光合产物,除用于当年的生长发育之外,同时将多余的贮藏性物质(主要指可溶性糖

| Abstract: | Present paper disccuses seasonal dynamics of sacharide and protein content in Leymus chinensis growing in different habitats which are natural grassland, pasture grassland (under grazing and over grazing), hay grassland and irrigated grassland. Acceding to several year investigations, the interrelation of the seasonal dynamics of the substance content to the development of Leymus chinensis is reported and the regularity of interrelation between the sacharide content of rhizome and the biomass on the aerial ... |
