摘要：香梓楠为热带南亚热带珍贵优良用材树种,使用轻基质网袋育苗,具有重量轻、通气透水性好和方便种植等特点,可以提高造林成活率和降低造林成本。选择树皮和锯末为基质原料,经晒干、粉碎、过筛、堆沤后,按一定比例把拌匀的基质灌装至网袋内制成育苗容器。香梓楠种子经催芽后移植至容器内,注意淋水,保持湿润;每半个月施肥一次,以氮肥和复合肥为主,宜勤施薄施:当苗高约15 cm时,移疏苗木,并适时进行空气修根,促进侧根的生长;约11月中旬以后可实施炼苗,当苗龄达12个月,苗高达45cm以上时,苗木可出圃造林。
Michelia hedyosperma is a superior timber tree species in the south subtropical area.The use of light mesh bag seedling substrate which is light weight,good ventilation and permeability,and convenient to plant,can improve the survival rate and reduce the cost of afforestation.In the paper,bark and sawdust were selected as a substrate material and mixed with a certain proportion after drying,crushing,sieving and steep piling,to make nursery container bags.Michelia hedyosperma germination after seeds were transplanted to the containers and maintained at a certain moisture content;nitrogen and compound chemical fertilizer were applied once every two weeks.When the seedling height is about 15cm,shift thinning and timely root trimming should be applied in order to promote the growth of the lateral roots;after mid-November hardening-seedlings can be implemented;when the seedling is 12 months and up to 45 cm,the seedlings can be used in afforestation.
