摘要

为探明建筑回填土条件下草坪草种植的适宜性以及再生水灌溉对草坪草生长和土壤理化性质的影响情况，选用黑麦草为试验对象，通过室内盆栽试验的方式，设置清水灌溉、再生水灌溉、清水—再生水交替灌溉3个处理，研究了呼和浩特市建筑回填土灌溉再生水对草坪草生长及土壤理化性质的影响。试验发现：(1)与清水灌溉相比，清水—再生水交替灌溉、再生水灌溉下的草坪草生长速率分别增长了23%，34%。(2)各处理草坪草在质地、盖度、均一性方面的得分表现为再生水灌溉＞清水—再生水交替灌溉＞清水灌溉，但差异性不显著（P＞0.05）。(3)到观测结束期时，再生水、清水—再生水交替灌溉下的土壤全盐量较对照组分别增加了8%，3%。(4)不同灌溉水质下黑麦草对土壤重金属的富集具有差异性，土壤中重金属含量有增有减。试验结果表明，再生水灌溉对草坪草的生长速率有很明显的促进作用，草坪草的颜色在再生水灌溉下要显著优于其他处理（P＜0.05）。同时，对试验土壤及草坪草的后期分析能够发现，短期内再生水灌溉下的土壤不会对草坪草产生盐害，土壤也均未受到污染，可见短期内建筑回填土下使用再生水灌溉草坪草是可行的。

Abstract

To explore the suitability of grass planting one lawn under backfill conditions as well as the impact of irrigation with reclaimed water on grass growth and soil properties. This paper chooses Lolium perenne as the test subject by setting up three groups

fresh water irrigation

reclaimed water irrigation and fresh+reclaimed water alternative irrigation in the form of indoor pot experiment. It studies the impact of irrigation with reclaimed water on grass growth and soil properties in Hohhot. The results showed as follows: (1) Compared with fresh water irrigation

lawn with fresh+reclaimed alternative irrigation and reclaimed water grows by 23% and 34% respectively. (2) The scores of quality

coverage and evenness of lawns indicate: reclaimed water irrigation＞fresh+reclaimed alternative irrigation＞fresh water irrigation. But the difference is not significant (P＞0.05). (3)When the observation is ended

the salt of soil irrigated by fresh+reclaimed alternative irrigation and reclaimed water increases by 8% and 3% respectively. (4) With different irrigating waters

Lolium perenne’s absorption of soil heavy metals varies and the heavy metal contents are different in the soil. The results showed that reclaimed water irrigation has an obvious role in enhancing the growth rate of the lawn and the color of the lawn irrigated by reclaimed water is visibly better than others (P＜0.05). At the same time

the further analysis of test soil and lawn showed that claimed water irrigation will not impose soil damage on lawns and soil is not affected. It can be seen that it is feasible to irrigate lawn with reclaimed under backfill conditions in the short term.
