太行山南端主要造林树种适生范围及造林技术调查研究

本文研究了太行山南端的自然特点,调查了森林植被的垂直分布和不同土类条件下的生长规律,在总结了多年造林实践基础上,明确提出油松、栎类、侧柏、剌槐等主要造林树种的三个垂直区划带,井对其适生范围,生长指标和造林技术作了探讨,为造林选择树种、提高成活率和生长量提出了科学依据。

SURVEY AND RESEARCH FOR THE GROWING RANGE OF PRINCIPAL TREE SEEDS OF PLANTATION IN THE SOUTH END OF TAIHANG MOUNTAINS AND AFFORESTATION TECHNIQUE

In this paper the natural feature of the south end of Taihang Mountains,the vertical distribution of forest vegetation and its growing laws under the condition of different kinds of soil are studied.On the basis of summarizing the afforestation practice of many years we have proposed apparently three vertical division belts of principal treeseeds such as chinese pine,oak,oriental arborvitae and so on.We have studied the range suitable for their growth,the growing index and afforestation technique.Thus the scientifical foundation is given forchoosing planting seeds and making mountainous district green.
