摘 要:在山西省5个不同立地区进行美国黄松造林试验,对不同立地条件对造林成活率、树高和地径的影响进行了分析,结果表明:美国黄松在山西不同立地区生长适应性比较强,生长量较大,无病虫害。在不同海拔梯度下美国黄松树高和地径年生长量并无显著差异,在左云、静乐、阳城不同海拔条件下,美国黄松与油松树高、地径生长量均无显著差异,生长量表现不亚于油松,为此,可以初步认为:美国黄松适宜在山西省不同立地区生长。Afforestation experiment of Pinus tabuliformis was conducted in 5 different districts of Shanxi Province,and the effects of different site conditions on the survival rate,tree height and ground diameter of afforestation were analyzed.The results showed that Pinus ponderosa had strong adaptability to growth in different sites of Shanxi Province,with large growth volume and no pests and diseases.Under different altitude gradients,different precipitation,and annual average temperature,there is no significant difference in the annual growth of the height and ground diameter of the Pinus ponderosa.Under different altitude conditions of Zuoyun,Jingle,and Yangcheng,there is no significant difference in the height and ground diameter growth of Pinus ponderosa and Pinus tabuliformis.The growth performance is not inferior to that of Pinus tabuliformis.It can be preliminarily considered that the Pinus ponderosa is suitable for growth in different regions of Shanxi Province.
