积石柳是新近定名的柳树新种。研究结果表明，为中生阳性乔木，抗寒，适应性强，繁殖简便，速生，萌芽性强，生物量大，物理力学性能良好。叶片栅栏组织约占叶片总厚度的70％；愈伤组织生根数占70％。不定芽生根数占30％，一年内地径有三个生长高峰，树高有两个生长高峰；11年内胸径，材积尚处于速生阶段，而树高第4年达最高峰后进入缓慢生长阶段。生物量预测的最佳方程有二种，即枝生物量W1=0.0553D（2.5186）H（0.0156），叶生物量W2＝0.0322D（1.7172）H（0.3551）。
Shimen Liu is a newly named new willow species. The results show that, for the Mesozoic tree, cold, adaptability, easy propagation, fast growing, sprouting, biomass, good physical and mechanical properties. Leaf palisade tissue accounted for about 70% of the total leaf thickness; callus rooting accounted for 70%. The number of adventitious buds accounted for 30% of the total number of root growth in the year there are three growth peaks, tree height has two growth peaks; 11 years, DBH, volume is still in fast growth stage, and reached the peak in the fourth year after entering the slow growth stage. The optimal equation for biomass prediction is twofold: branch biomass W1 = 0.0553D (2.5186) H (0.0156), leaf biomass W2 = 0.0322D (1.7172) H (0.3551).
