摘　　要：为获得大量白及(Bletilla striata)种苗,扩大栽培种植面积,实现白及规模化大田生产,试验采用3因素3水平正交试验对白及种子生长环境条件进行了研究。结果表明,基质配比育苗基质∶腐熟有机质=1∶1、温度25℃、光照时长16 h/d、湿度为100%的环境组合对白及种子生长最有利,出苗率达到69.45%。各因素的影响程度为温度>基质配比>光照时长。In order to obtain a large number of Bletilla striata seedlings,expand the cultivated area and realize the large-scale field production,L9（33） orthogonal experiment was conducted to study the environmental conditions of B. Striata seeds.The results showed that,the combination of substrate with seedling substrate∶matured organic matter=1∶1,temperature 25 ℃,light duration 16 h/d and humidity 100% was the most favorable for the germination of B. striata seeds,with the emergence rate reaching up to 69.45%. The impact degree of temperature was the biggest,followed by matrix ratio,and the third was illumination duration.
