无土栽培中不同基质对草坪草生长的影响

Influence of Different Culture Medium on Growth of Lawn Grass under Soilless Culture

利用珍珠岩、锯末、煤渣、砂作基质代替土壤进行无土栽培草皮试验 ,通过测定不同基质的保水性能、草皮成卷时间、草皮重等指标 ,并采用方差分析及灰色系统理论中的关联分析法进行综合评估分析表明 ,珍珠岩作基质在无土栽培草皮中效果最佳 ,其次为锯末、煤渣 。

The trials for soilless culture of lawn grass were conducted with pearlite, sawdust, coal ash and sand as culture medium instead of soil. The result indicated that among the culture medium, the pearlite is the best sawdust and coal ash the second and the worst is sand viewing from the measurement of its moisture maintenance, the time for soil and the weight of grass by means of variance analysis and interaction analysis of the Grey theory to the data.
