摘要: 为了研究化学控根在容器育苗中的作用,总结了化学控根的研究进展、原理、技术与方法,分析了化学控根的目的是防止栽培于容器中的苗木根系产生畸形。指出化学控根剂可以防止根系缠绕和生长畸形,进而提高根系对水分和养分的吸收,提高苗木的成活率并促进后期生长。目前常用的化学控根试剂主要是铜(Cu)试剂和锌(Zn)试剂,还有氟乐灵、乙烯磷以及生长调节剂等。通过分析,我们认为目前化学控根主要应用于木本植物的容器育苗,木本植物主根较为发达,化学控根是有效控制木本植物容器苗根系发育的主要手段之一,对提高苗木质量具有重要研究意义。

Abstract: To evaluate the functions of chemical root-control technology in container seedlings, we reviewed the research progress, theories, techniques and methods of chemical root-control. The main purpose of the root-control technology is to prevent the deformity of the root system of the seedlings planted in containers. Chemical root-control agents can prevent roots from twining and hyperplasia, promote uptake of water and nutrients, and therefore increase the survival rates of the seedlings and promote the growth during later stages. At present, copper (Cu) and zinc (Zn) reagents are widely used, as well as trifluralin, ethylene phosphorus and growth regulators. Chemical root-control technology is mainly applied to container breeding of woody plants because woody plants have strong taproots. Chemical root-control is one of the important technologies to effectively control root development and is essential for improving the quality of seedlings of woody plants.
