摘要
针对福清沿海岩岸低效黑松防护林现状,采用不同整地方式、不同苗木、不同造林密度及不同抚育施肥措施,对1 500hm2的低效黑松防护林进行更新改造试验。结果表明,厚荚相思和马占相思是适宜的更新改造树种;迎风面采用条状劈带整地、块状挖穴,背风面采用全面劈杂炼山、块状挖穴,并进行施肥、抚育等措施,有利于提高更新造林的成活率、保存率,促进幼林的生长,使岩岸基干林带防护功能得到迅速恢复。
According to the present status of low-effect Pin us thunbergii for shelterbelt on Fuqing rocky coasts, The study on the transformation technique of low-effect Pinus thunbergii for shelterbelt by using different site preparation methods, different seedlings, different afforestation densities, and different tending and fertilizing measures. The result showed Acacia crassicarpa and Acacia mangium were suitable for afforestation species transformation. On the windward slope site preparation with strips or blocks and on the leeward the comprehensive bush clean and controlled burning, site preparation with blocks, fertilizing, tending were beneficial to improve regenerating afforestation rate and conservation rate, to promote the young tree growing, thus to restore shelterbelt function on rocky coasts rapidly.
