1962年开始,在东北西部农田防护林营造过程中,尝试性的采用油松(pinus tabulaeformis)和樟子松(pinus sylvestris var.mongolica)为主要造林树种、获得了良好结果。近年来,采用油松、樟子松营造农田防护林带已日益增多,范围也逐渐扩大。因此,加深对油松、樟子松生理生态特性的了解,对降低造林成本,增加林木生长量,提高防护效能,加速这一地区大自然改造,将具有重要意义。
Beginning in 1962, good results were obtained using the pinus tabulaeformis and pinus sylvestris var. Mongolica as the main tree species for the construction of farmland shelterbelt in the western part of Northeast China. In recent years, the use of Pinus tabulaeformis, Pinus sylvestris to create farmland shelterbelts has been increasing, the scope also gradually expanded. Therefore, to deepen the understanding of the physiological and ecological characteristics of Pinus tabulaeformis and Pinus sylvestris var. Mongolica will be of great significance to reduce the cost of afforestation, increase the growth of trees, improve the protective efficacy and accelerate the transformation of nature in this area.
