摘 要:为提高困难立地的造林成活率,减轻风沙危害,在位于北京市北部的延庆县龙庆峡荒滩布置固体水造林的应用试验。试验过程中调查苗木的成活率和相关生长指标,并应用统计软件S-PLUS分析、研究固体水的应用效果。结果表明:在造林后的前3个月内,固体水能够显著提高造林成活率,苗木成活率均超过90%;固体水施用量的增加对苗木的成活率和相关生长指标的影响呈相应增加趋势;固体水缓释供水、持续供水和无渗漏等特点,使固体水造林技术更适合在干旱缺水、灌溉困难的地区推广应用。In order to enhance survival rate of trees planted in difficult sites and reduce sandstorm harm to Beijing, solid water application experiment was carried out for afforestation in the desolate alluvial flat of Longqingxia in Yanqing County of Beijing. Through statistical software S-PLUS, the survival rate and relevant growth indexes of plants were analyzed so as to study the application effect of solid water. The result indicated that in the first three months the solid water can enhance afforestation survival rate prominently which is over 90%. Meanwhile, with the increased employment quantity of solid water, the survival rate and relevant growth indexes of plants increased correspondingly. The slow release of water and constant water supply without leakage make the afforestation technology of solid water more suitable for application in arid areas where irrigation is difficult in production.
