Introduction Experiment of Sand Control Tree Species in Yuyang District,Shaanxi Province
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.
