| Abstract: | ＇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. |
