当前营造混交林,日益为林业生产、科研及教育部门所重视。我国南方地域广阔,自然条件多种多样,在建设以杉木为主的用材林基地的同时,应该根据各地区不同的立地条件,选择适宜的造林树种,进行多种形式的混交造林。各地区的实践证明,在我国南方发展混交林既是提高林分生产力的重要条件,又是扩大杉木栽培范围和克服杉木纯林一些缺点的有效措 At present, the construction of mixed forests is increasingly valued by forestry production, scientific research and education departments. While southern China has a vast geographical area and diverse natural conditions, it is necessary to select suitable afforestation species and carry out various forms of mixed afforestation according to the different site conditions in different regions while building a woodland base mainly consisting of fir. Practice in various regions proves that the development of mixed-use forests in southern China is not only an important condition for improving stand productivity, but also an effective measure to expand the scope of fir cultivation and overcome some shortcomings of pure Chinese fir plantation
