摘  要：
以粉煤灰、腐殖土、水和绿矾作为草坪砖基质主要成分进行配合比设计,研究高羊茅、黑麦草、匍匐剪股颖3种草分别在4种配方条件下的植生效果,筛选了3种草各自适宜的基质配方。试验结果表明:在配方2 (粉煤灰∶腐殖土∶水∶绿矾=10∶20∶20∶1)条件下,3种草发芽数均可达最高,且高羊茅和黑麦草的株高最高;不同配方对3种草的颜色和质地没有显著影响,但配方1 (粉煤灰∶腐殖土∶水∶绿矾=10∶10∶10∶1)和配方2对于改善3种草的绿期、盖度和生物量等生长质量具有最佳效果;对于3种草而言,高羊茅在配方2条件下生态质量指标表现最好,而黑麦草和匍匐剪股颖则在配方1条件下表现最好,综合评分表明,高羊茅更适合作为植生草种。研究结果为草坪砖-基质配制及适生草种的选择提供了依据。

摘  要：
To screen the favorable substrates for lawn brick,four proportions mixed with the major components including fly ash,humus soil,water and Fe SO_4·7H_2O were established,on which Lolium perenne,Festuca elata,Agrostis stolonifera were grown respectively to detect the plant-growing effect.The results indicated that the seeds of all the three grass species germinated the most on the substrate mixed using proportion 2 (fly ash∶humus soil:water∶FeSO_4·7H_2O=10∶20∶20∶1) compared with other proportions and the plant height of Festuca elata and Lolium perenne could reach the highest level.No significant effect on the color as well as texture of the three grass lawns could be observed among the four proportions.However,the grouting substrate mixed using proportion 1 (fly ash:humus soil∶water∶FeSO_4·7H_2O=10∶10∶10∶1) and proportion 2 could improve best on the growing quality of lawn green period,coverage and biomass.For the three grass species,Festuca elata grown in the grouting substrate mixed using proportion 2 had the best performance of ecological quality while Lolium perenne and Agrostis stolonifera performed the best using proportion 1.Compared with comprehensive scores,Festuca elata was the most suitable grass species grown in lawn brick-substrates conditions.The investigation provide a basis for the preparation substrates and the selection of grass species for lawn bricks.
