摘要
采用全垦加大穴的造林方法,在湖南省的嘉禾县和邵东县石灰岩发育的红壤上进行了棱角山矾的应用示范林营造,其初步结果是:①嘉禾县应用示范点造林5年的棱角山矾胸径、树高平均年生长量分别达1.4 cm和60.8 cm,最大株胸径、树高年生长量分别达1.7 cm和84 cm,造林成活率达95%,保存率达90%;邵东县造林2.5年的棱角山矾地径、树高平均生长量分别达0.98 cm和84.8 cm,造林成活率达93%,保存率达87%。②棱角山矾适应性强,长势好,生长较快,是中度和轻度石漠化治理的优良树种。
Using both whole reclamation and large-dug-hole methods,the application demonstration forest of Symplocos tetragona was constructed in the red soil,which originated from calcareous rock,in Jiahe County and Shaodong County in Hunan Province.The primary results showed as follows： ① The DHB（diameter at breast height） and height average year growth quantity of S.tetragona,whose afforestation age is five is 1.4 cm and 60.8 cm respectively,and the biggest DHB and highest height of single plant average year growth quantity of S.tetragona＇s maximal tree is 1.7 cm and 84 cm respectively,and the survival rate and preservation rate of S.tetragona are 95 % and 90 % respectively in Jiahe County.The DHG（diameter at ground height） and height average growth quantity of S.tetragona,whose afforestation age is two and half years is 0.98 cm and 84.8 cm respectively,and the survival rate and preservation rate of S.tetragona are 93 % and 87 % respectively in Shaodong County.②S.tetragona has a strong adaptability and nice growing power and quicker growth quantity,and S.tetragona is excellent tree species of middle and low-grade stony desertification control.
