通过对樟子松在甘肃干旱区的适应性进行研究分析得出:樟子松的耐旱性强于当地主要防护林树种二白杨和沙枣;也较常绿乡土树种侧柏、油松、刺柏、青海云杉适应性强,并表现出明显的生长优势。对樟子松的生长量、移栽造林技术、光合速率、蒸腾强度、水分利用效率、耐盐性、物候期等进行研究的结果表明:樟子松能适应甘肃干旱区气候、自然生态环境条件;同时长势也优于原产地,是优良的防风固沙造林树种,能抗病虫害、可作为用材林树种,改造当地“小老头树”防护林等,其发展潜力大,应大力发展。
Through the study on the adaptability of Pinus sylvestris var.mongolica in the arid region of Gansu, it is concluded that the drought tolerance of Pinus sylvestris var. Mongolica is stronger than that of the main shelterbelt Populus euphratica and Elaeagnus angustifolia; , Qinghai spruce adaptability, and showed obvious growth advantages. The results showed that Pinus sylvestris var. Mongolica could adapt to the climatic conditions and natural ecological environment of arid areas in Gansu Province. The results showed that Pinus sylvestris var. At the same time, its growth is better than its origin. It is an excellent windbreak and sand fixation afforestation species, capable of resisting diseases and pests. It can be used as a timber species to transform the local “small old tree” shelterbelt. Its development potential is great and should be greatly developed.
