樟子松容器苗抗旱造林技术研究

樟子松针叶短小、根系深长,耐旱、耐寒、抗风性强,是北方营造防风固沙林、水源涵养林的重要树种。针对北方干旱瘠薄阳坡、沙地裸根苗造林成活率低,多次造林不成功的现状,木兰林管局结合生产,开展了樟子松容器苗造林技术研究。用山皮土配制营养土,选择2 a以上合格苗培育容器苗上山造林较常规裸根苗造林方法大幅度提高了造林成活率和保存率,缩短了缓苗期,促进了幼树生长,保证了一次造林,一次成林,是一项成功的抗旱造林技术措施。

A technology reserch on container seedling afforestation of scotch pine

Scotch pine's needles are short,its roots are deep,it can resist cold and drought,so it is an important tree species for North China to creat Sand-Fixation Forest and Water Resource Conservation Forest.In the north,due to the afforestation survival rate of truncated plant in the sand of dry barren sunny slope is low,and multiple of afforestation fail.According to this,combining production,Mulan Forest Bureau does the tecnology reserch on container seedling afforestation of Scotch pine.It proves that: comparing the normal method of truncated plant afforestation,compounding nutrient soil with hill-skill soil and chosing more than two years'qualified seedling to cultivate Scotch pine for the afforestation on the hill improve the afforestation survival rate and preserving rate greatly,shorten the revival time,promote the young tree's growth,ensure that afforestation one time,forest establishment one time,and is a successful drought-resistant afforestation measurement,shoud be popularized positively.
