本研究采用大样本随机挖取单个无性系株丛的方法在伊犁河谷特克斯县境内的典型白羊草(Bothriochloaischaemum)草地进行取样,并定量分析了白羊草无性系构件结构及其生长规律。结果表明,在籽实成熟期,白羊草无性系的平均丛径为13.5cm。在无性系中,生殖分株与营养分株分别占总分株的27.9%和72.1%,而生殖分株与营养分株的生物量则分别是无性系总生物量的50.6%和49.4%。随着丛径的增加,白羊草无性系不同构件数量和生物量及总分株数量和分株总生物量均呈指数函数关系的异速增长。营养分株数量和生物量与总分株数量及总生物量之间呈幂函数关系,而生殖分株数量和生物量与总分株数量及分株总生物量之间均呈线性相关关系。
In this study, a large sample of a random clonal clump method of cloning in the Ili Valley, Nexus Turkestan typical two species (Bothriochloaischaemum) grassland sampling, and quantitative analysis of the structure of the Leymus chinensis clonal components and their growth patterns . The results showed that the mean diameter of the climaxes of A. chinensis clones was 13.5 cm at the maturity stage. In clones, the reproductive ramets and vegetative ramets accounted for 27.9% and 72.1% of the total ramets respectively, while the biomass of reproductive ramets and vegetative ramets were 50.6% and 49.4% of the total clones respectively. With the increase of bush diameter, the number of different components of A. chinensis clones and the biomass and the total number of ramets and ramet total biomass all showed an exponential growth relationship. There was a linear relationship between the number of vegetative ramets, the biomass and the total number of ramets and the total biomass, while the number of reproductive ramets and biomass correlated linearly with the total number of ramets and total ramet.
