摘　　要：本文以无土栽培的方法,对建兰设计了4种有机和无机混合的基质配方进行栽培观察筛选。在实验期间,分别对不同基质配方的理化指标如:总孔隙度,通气孔隙度、最大持水量、pH值、EC值、基质阳离子交换量进行分析比较,并对建兰的出芽率、芽苗增高量、干鲜重、含水量、叶片叶绿素含量以及根系活力进行观察、分析和统计比较,最后综合得出:最适合建兰生长的基质配方是花岗岩:花生壳(4:6)。To solve the problem the confused application of unqualified soilless cultures in the commercial orchid cultivation which seriously affected orchid quality, we designed and tested through soilless culture 4 organic and machine mixed matrix formula for Cymbidium ensifolium. During the experiment follwing matrix characteristics and plant characteristics were determined matrix formulations：total porosity, aeration porosity, maximum water holding capacity, pH value, EC value, cation exchange capacity; budding rate of orchids, increased bud height, dry and fresh weight, water content, leaf chlorophyll content and root activity. Statistical analysis of the results showed ： that the best formula for Cymbidium ensifolium was ：granite matrix with peanut shell （4：6）.
