Abstract

Abstract: Based on the experimental data,a characteristic and process for the shoot number changing of Stipa bveviflora were expounded,and its cause was analy-zed.A quantitative model of the ralationship between its shoot number and po-pulation yield was pointed out,as well did the optimum density range of vege-tative shoot of Stipa breviflova in this paper,which provided a theoretical basis for Stipa breviflora Desert-Steppe rational utilization.

Key words: Stipa breviflora, shoot number changing, population yield, tiller

摘要： 本文阐述了短花针茅(Stipa breviflora Grisb.)枝条数的消长特征与消长过程,分析了其消长的原因,提出了枝条数与种群产量关系的定量模型以及短花针茅营养枝的最适密度范围,为短花针茅草原的合理利用提供了理论依据。

关键词: 短花针茅, 枝条数消长, 种群产量, 分蘖
