摘 要:为摸清贵州省现有油茶低产林的类型和经营状况,笔者对贵州省5个重点油茶产区(县)进行了调查,在样块、样地、林分测定的基础上,分析了油茶低产林的成因,划分了2个油茶低产林类型及5个亚类型,确定了4个油茶低产林经营类型,提出了各经营类型的经营技术。To find out the existing types and operating status of low-yield O. camellia forests in Guizhou province, the causes of low-yield O. camellia forests were analyzed after surveying the five key O. camellia producing districts and analyzing the kind of block, plot and standing forest. Two major types of low-yield O. camellia forests, five types of low-yield O. camellia forests were classified and four management types of low-yield O. camellia forests were figured out and the management techniques of different management types were proposed as well.
