以草牧场防护林的主要组成树种—樟子松、兴安落叶松和各品种杨树作为研究对象,采用设置标准地的方法,重点调查了樟子松、兴安落叶松和中东杨在不同土壤类型上以及其他主要杨树品种与樟子松在相同土壤类型上的生长状况。通过对它们生长指标的直观比较和分析,提出了樟子松、兴安落叶松、中东杨和其他各品种杨树适生的土壤类型,为该地区成功营造草牧场防护林提供基础数据和理论依据。
Taking the main tree species of shelterbelt (Pinus sylvestris var. Mongolica), Larix gmelinii (Larix gmelinii) and all varieties of poplar as the research object, the methods of standard setting were used to investigate the effects of Pinus sylvestris var. Mongolica and Populus davidiana on different soil types As well as the growth of other major poplar species and Pinus sylvestris var. Mongolica on the same soil type. Through the direct comparison and analysis of their growth indexes, the suitable soil types of poplar, Pinus sylvestris var. Mongolica, Populus davidiana, poplar and other varieties were put forward to provide the basic data and theoretical basis for the successful establishment of the shelterbelt in the area.
