| 摘 要： | 以播种当年的草坪为研究对象,从苗期开始对草坪草进行梯度遮阴处理,观测草坪草的生长情况研究结果表明,遮阴促进植株的高生长,并且随遮阴强度增加,株高的生长呈先增后降的变化规律,以遮阴45%的株高最高;植株的单株重量以不遮阴的全光照最重,并且随遮阴增加单株重逐渐下降;根系长度也逐渐变短,地卜的枝条密度与单株重的变化一致.遮阴度过高对草地早熟禾草坪的生长和建成有严重影响.

| Abstract: | In this paper,Sowning turfgrasses in the same year as research object,we made gradient shading for them and observed and measured their growth from the beginning of turfgrasses seedling.The result showed that the plant height was improved by shading,and the change trend of plant height was increased first and then decreased,and it indicated the biggest value that the shade 45%of the plant was the highest.The weight of individual plant was the biggest without shading,and it was decreased as shade increased,a... |
