摘　　要：播种后光照能明显地提高发芽率,发芽指数和幼苗的质量,浸种时光照和不同浸种时间,对发芽率影响具有统计学意义。播前在日照下浸种72小时,播后遮荫育苗,优于播前暗处理浸种和播后暗处理育苗的组合。After sowed, the germination rate, germination index and the quality of seedlings in deodar cedar can be improved by illumination.The seed immersed for 72 hours in sunlight, and shaded to culture seedlings after sowed, the results should be better than that in compound treatment such as dark treatment for seeds befor sowing and dark treatment for seedlings after sowing.
