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。
In the cultivation of the matrix filled with waste rubber particles, planting ryegrass lawn, the study before and after trampling changes in its biological characteristics. The results showed that the number of stems and the coverage of stems increased with the decrease of the size of the colloidal particles, and all the colloidal particles were obviously higher than those without colloidal particles (control) But showed the opposite trend, which increased with the particle size increased, and were higher than the control. Under the trampling stress, the coverage of ryegrass, aboveground biomass and tiller number showed the same rule, which increased with the decrease of particle size, and the highest particle size was 1-2 mm, and all the particles were better than Control. Trampling under stress causes ryegrass stems and leaves more damage. Under trampling stress, root quality was the highest at 1 ~ 2 mm, which was 138.77% higher than the control. The comprehensive analysis shows that the matrix-filled rubber particles can increase the anti-trampling ability of the turf, which is closely related to the elastic characteristics of the rubber particles. Among the three kinds of rubber particles, 1 ~ 2mm rubber particles are obviously superior to other rubber particles, Unfilled micelles.
