无芒雀麦叶组织物质周转规律及其与草地管理的关系

对无芒雀麦叶组织物质周进行了研究，结果表明，在生长期无芒雀麦净叶数和净叶伸长生长符合抛物线变动规律，叶累积死亡和累积枯萎长度按直线规律增长，根据植物种群生态学生物统计分析原理，还探讨了叶组织周转规律与草地合理利用的关系。

The law of Leaf Tissue Turnover of Smooth Bromegrass and the Relationship with Grassland Management

Studying on the leaf tissue turnover of Smooth bromegrass was reported.The results were that the net number and the extension growth length of leaves in this grass species might be described by a dynamic law of a parabola equation,and the cumulative length of leaves Senescence and the numbe of leaves death might be represented by a linear functiou over grouth seasion.This paper also discussed the relationship between the law of leaves tissue turnover and the rational utilazation of the grassland,depending on the demographic analysis method With pland population ecology.
