11个造林树种在京北荒滩应用固体水效果比较研究

Comparison of Eleven Afforestation Tree Species Using Solid Water on Wasteland in the North of Beijing

以往研究表明,固体水能够提高造林成活率,特别在困难立地造林应用中已取得较好效果。为进一步选择应用固体水效果较好的树种,为今后困难立地造林树种选择提供参考,于2004年4月在北京市延庆县龙庆峡荒滩进行固体水多树种造林应用试验。通过分析树种成活率和相关生长指标,对比研究固体水多树种应用效果。结果表明,在荒滩造林绿化中,固体水能够提高各供试树种成活率和生长指标;银杏、旱柳、国槐、新疆杨、白榆、侧柏、刺槐、毛白杨和樟子松等9个树种应用固体水效果较好。

Researches indicated that solid water can enhance the survival rate of trees, especially in difficult site ,satisfactory effects of afforestation could be obtained. Experiment of afforestation with multiple tree species using solid water was carried out on the wasteland of Longqingxia in Yanqing County, Beijing to select suitable tree species. Through analyzing survival rate and correlative growth indeice of nursery stocks, application effect of multiple tree species using solid water was contrastively studied. The result indicated that on the wasteland solid water can enhance survival rate and growth indices of the tree species, and nine tree species using solid water had good application effect.
