用 25、50、100ug/g 的 A B T 生根粉3 号浸泡华北落叶松苗木根系4h 后造林,结果表明,生根粉在华北落叶松造林中效果明显,用50ug/g 生根粉浸根可使造林成活率提高10 个百分点,用 25ug/g 浸根可使苗木生物量、苗高和地径分别提高38.2% 、7.3% 和18.8% 。
Roots of Larix principis-rupprechtii were inoculated with 25, 50 and 100ug / g of ABT rooting powder 3 for 4h. The results showed that the rooting powder was effective in afforestation of Larix principis-rupprechtii. The survival rate of afforestation increased by 10 percentage points. With 25ug / g immersion root, seedling biomass, seedling height and diameter increased by 38.2%, 7.3% and 18.8% respectively.
