摘 要:
对羽叶山黄麻进行了苗木培育和造林试验,结果表明:不同育苗方式苗期生长差异明显;育苗方式对造林成活率和苗木生长影响明显,大田苗造林成活率极低,塑料袋容器苗造林后缓苗现象明显,对伏旱季节的适应能力差;黑色硬质塑料控根容器苗造林后能平稳生长,受伏旱季节影响不明显;直播造林苗分异明显,优势株形成后,表现出较强的生长势;不同的整地方式和地面覆盖对成活率无明显影响,但对苗木地径生长影响明显,爆破整地明显有利于苗木地径生长;羽叶山黄麻用于岩溶峡谷石漠化地区植被恢复,在松动土石坡可优先选用直播方式造林,在土层浅薄的石漠化灌草地块造林,可选黑色用硬质塑料控根容器苗。

摘 要:
Nursery stock cultivation and afforestation of Trema ofienali Hand-Mazz were tested.Results indicated that there were evident differences on seedling growth in seeding time by different ways of nursery stock cultivation.Different ways of nursery stock cultivation had evident influences on survival ratio and growth of seedlings.Field seedlings showed low survival ratio.Seedlings being seeded in plastic bag caused seedlings growing lowly after afforestation and adapted poorly in summer drought.Seedings being seeded in horniness plastic container brought seedlings common growth after afforestation and weren't influenced greatly by summer drought;The differentiation of seedlings seeded derectly was obviously.Once field seedlings formed advantage plant,it would show strong growth potential.Different scarification and soil mulch didn't have evident influences on survival ratio of seedlings,but influenced root diameter growth evidently,scarification by blowing up was beneficial to root diameter growth evidently.Trema ofienali Hand-Mazz should be used for revegetation,while direct seeding was selected primely for afforestation in looseness stone and soil sloping.Rigid plastic container seedlings root control were selected for afforestation in thin soil of stony desertification grassland.
