摘要
本文旨在研究陕西省榆阳区引种青海云杉、白刺、沙柳、刺槐的实验,对它们各自的苗木进行实验,并对苗木的高度生长量、地径生长量、成活率以及保存率进行相关数据统计.结果表明,苗高方面刺槐表现最好.地径方面沙柳表现稍微优于其他树种,但整体增长不大.冠幅方面白刺和沙柳表现最好.成活率和保存率四种树种的表现均较好,其中白刺的三年保存率最高.同时,还需要进一步对这些实验树种继续进行评估和推广.
Abstract
This article aims to study the experiment of introducing Qinghai spruce,white thorn,sand willow,and black locust in Yuyang District,Shaanxi Province,conducting experiments on their respective seedlings,and conducting relevant data statistics on the height growth,ground diameter growth,survival rate,and preservation rate of the seedlings.The results showed that Robinia pseud-oacacia performed the best in terms of seedling height.In terms of ground diameter,Salix psammophila performs slightly better than other tree species,but the overall growth is not significant.White thorn and sand willow perform best in terms of crown size.The surviv-al rate and preservation rate of the four tree species were all good,with White thorn having the highest three-year preservation rate.At the same time,further evaluation and promotion of these experimental tree species are needed.
