光照强度与基质种类对室内立体种植地毯草无土草坪的影响

Effect of Light Intensity and Substrate Type on Indoor Vertical Planting of Carpet Grass for Soilless Lawn

为探究光照强度与基质种类对室内立体种植无土草坪的影响,以我国南方常用绿地草坪类型地毯草为研究对象,分别设置了弱光照强度与基质种类各3个梯度水平共9个试验处理,测量了其表观质量水平,计算了不同试验处理的生产成本。结果表明:光照强度和泥炭在基质中所占比重越高、草坪表观质量水平表现越好,光照强度对草坪外观质量水平的影响远高于基质组成,不同处理间生产成本差异高于表观质量水平差异。综合比较表观质量指标和生产成本的变化,选择光照强度8000 lx、泥炭和椰糠等体积比例混合的基质生产无土草坪效果较好,可以为室内立体种植无土草坪的实际应用提供理论依据和实践指导。

In order to investigate the effect of light intensity and substrate type on indoor vertical planting of carpet grass for soilless lawn,commonly used green lawn type in southern China,was taken as the object.This study set up a total of 9 groups of experimental treatments with three-gradient level of weak light intensity and substrate type respectively,measured their apparent quality levels and calculated the production costs of different experimental treatment groups.The results showed that the higher the light intensity and the proportion of peat in the substrate,the better the apparent quality level of the lawn,the effect of light intensity on the appearance of the lawn quality level is much higher than the composition of the substrate,and the difference in the production cost between the different treatments is higher than the difference in the apparent quality level.Comprehensively comparing the changes in apparent quality indexes and production costs,it is better to choose a mixture of substrates with a light intensity of 8000 lx,peat and coir in equal volume proportions to produce a soilless lawn,which can provide theoretical basis and practical guidance for the practical application of indoor vertical planting of soilless lawn.
