摘要
通过应用 10 8生根宝不同浓度溶液沾根处理 ,云杉、落叶松、红松换床苗的成活率、苗高、地径、主根长、侧根数及新播苗的保苗率等均比对照有所提高。结果表明 :换床苗适宜浓度为 2‰ ,新播苗适宜浓度为 0 .5‰～ 1.0‰。
Using root dipping treatment with different concentrations of'108'rhizoncaline,applied experiment was done.Results Showed that survival rate,height of seedlings,ground diameter,length of principle root and amoant of lateral roots of spruce,larch and red pine is higher than check,with 2‰ of concentration for transplanted seedlings and 0.5‰～1‰ of concentration for non-transplanted.
