摘　　要：设置了4种不同的遮光处理:全光照、遮光度40%、遮光度60%、遮光度70%,探讨不同遮光度对红椎大田播种育苗苗木保存率和苗木生长的影响。结果表明:遮光度对红椎大田播种育苗苗木保存率和苗木生长有显著影响。遮光度达70%时,其苗木保存率、苗木高生长与地径生长均表现最佳。＇4 shade treatments of full light, 40% shade rate, 60% shade rate and 70% shade rate were set to investigate their effects on the survival rate and growth of field sowing seedlings of Castanopsis hystrix. The results showed that, there was an significant influence on seedling survival rate and growth condition under various shade treatments. The treatment of 70% shade rate was best for seeding survival, seedling height and ground diameter growth of field sowing seedlings of Castanopsis hystrix.
