摘  要：
在栽培基质中填充废胶粒,建植黑麦草草坪,研究践踏前后其生物学特性的变化。结果表明:草坪建植第2年返青后,茎节数与盖度均随胶粒粒径的减小而增加,所有胶粒处理均明显高于无胶粒处理(对照);但茎枝长度却表现出相反的趋势,即随胶粒粒径的增加而增加,且均高于对照。践踏胁迫下,黑麦草盖度、地上生物量、分蘖数表现出一致的规律,即随胶粒粒径减小而增加,以1～2mm胶粒处理为最高,且所有胶粒处理均好于对照。践踏胁迫使黑麦草的茎节与叶片数损伤较大。践踏胁迫下,以1～2mm处理根质量为最高,高出对照138.77%。综合分析表明,基质填充废胶粒能增加草坪抗践踏能力,这与胶粒的弹性特征密切相关;在3种粒径胶粒中,以1～2mm胶粒明显优于其它粒径胶粒及未填充胶粒处理。

摘  要：
The biological characteristics such as the number of nodes,branch length,coverage,the number of leaves,tillers,overground biomass and root growth of Lolium perenne L.before and after trample stress were investigated by establishing turf system with waste crumb rubber as medium amendment.After lawn returning green in the second year,the number of nodes and coverage of L.perenne L.increased with the decrease of crumb rubber size,and all crumb rubber treatments were all distinctly higher than the treatment without crumb rubber(control) before trample stress,but the branch length showed the opposite trend,increased with the increase of crumb rubber size.Under trample stress,the coverage,overground biomass and tiller number of ryegrass(L.perenne)displayed the same rule.All of the parameters increased as decreasing crumb rubber sizes.The treatment with 1-2 mm appeared the highest,and all treatments with different crumb rubber sizes were better than control.Trample stress damaged the number of nodes and leaves greatly.In addition,the root biomass with 1-2 mm crumb rubber treatment under trample stress was the highest,and was higher 138.77% than control.So the waste crumb rubber filled in turf medium as amendment could enhance trample resistance of lawn based on above comprehensive analyses.This was directly correlated with elasticity of crumb rubber.In the three treatments,the size of 1-2 mm crumb rubber was the optimum medium amendment for sports lawn under trample stress,and the lawn character was clearly better than that of other treatments.
