【Abstract】 Castanopsis carlesii nursery and reforestation experiment were carried. Its seed germination and seedling were observed, as well as its young forest growth. The seedling growth period was divided using sequential sample cluster analysis,and seedling height growth process was fit using Logistic model, t its volume growth process was analyzed using stem analytical methods. The existing research and practice was summed up on the basis of investigation and nursery of natural forests, and afforestation experiments, the artificial cultivation techniques of C. carlesii were put forward.更多还原
