摘  要:
介绍了容器育苗的化学控根技术。以铜制剂为主的化学控根剂能缩短一级侧根长度,增加中上层根系的新根数量,改善根系结构,使得根系不再缠绕,它对苗木地上部分是否存在促进作用还存在争议。重金属铜对根系有生理伤害。铜控根剂在土壤中的释放遵循指数曲线,呈下降趋势,对土壤微生物也存在影响。

摘  要:
Root bound plugs decrease the quality of container seedlings,thus it is important to study the use of root-controling.The root controling technology includes air root controling,physical root controling and chemical root controling.The last one,with the emphasis on the copper products,can reduce the length of latter root,increase the numbers of the upper roots.The conclusion that chemical root-controling products can promote seedlings quality is under dispute.Copper root-controling product shall pollute the environment and injury plant physiologically.
