摘要
为进一步了解天然草与人造草混合系统草坪的特点,以纯天然草坪为对照,通过模拟践踏处理后,对混合系统草坪几项生理指标进行测定研究。结果表明:轻度践踏胁迫对混合系统草坪细胞质膜透性、叶绿素含量及可溶性糖含量的影响与不践踏时都达不到显著水平,SOD活性与MDA含量的变化也证实了这一点;而重度践踏在各方面都显著影响草坪草的生长,降低草坪质量;混合系统草坪中天然草受到人造草皮的保护,使草坪质量的稳定性加强,各项生理指标变化幅度降低。但是A2处理的人造草丝密度较大,影响了天然草的正常生长,草坪表观质量也较差;A8处理对天然草的保护作用不明显,与对照A0的差别不大;而A4、A6处理受践踏胁迫影响较小,对于天然草保护作用明显,显著提高了混合系统草坪的耐践踏性。
In order to further understand the characteristics of natural-artificial turf,the research tested some physiological indices of natural-artificial turf after mimic traffic processing,with the control group of natural turf.The results showed that the effects of light traffic on the plasma membrane permeability,chlorophyll content and soluble sugar content of natural-artificial turf were not obvious as those of non-traffic processing,and the changes of SOD activity and MDA content also proved this.However,heavy traffic had tremendous impacts on every aspects of turfgrass growth thus reducing turf quality.In natural-artificial turf system,the natural turfgrass was protected by the artificial turfgrass and the stability of the turf was strengthened so that the changes of every physiological index were smaller.But in group A2,due to the over density of artificial turfgrass,the growth of natural turfgrass was affected so that the visual quality of the turf was poor.The protection of artificial turfgrass was not obvious in group A8 compared with the control group A0.However,in group A4 and group A6,the turf was less impacted by traffic and the protection was very obvious thus greatly improving the traffic resistance of the natural-artificial turf.
