固沙灌木平茬现状及平茬控制钻蛀性害虫探讨

Status quo of stumping of sand-fixing shrubs and discussion on trunk borer control by stumping

平茬是将植株地上部分伐除,促使新枝萌发的一种营林抚育措施,是维持灌木林生态和经济效益的有效手段之一。适时、适当的平茬,不仅能促进林木再生,防止或延缓灌木林的自然衰退,而且能有效地控制病虫害,尤其是蛀干性害虫的危害。本文概述了几种固沙灌木的平茬及平茬防治钻蛀性害虫的现状,以期更好地促进平茬兼防治病虫害的深入研究和应用。

Stumping is one of tending measures in forest culture and management by cutting off overground parts of plants to get rejuvenation. After stumping,shoot production gets greater than before.Stumping is one of the effective means to maintain ecological and economic benefits of shrub wood.Appropriate stumping in right time not only promotes shrubs to rejuvenate,delay or prevent shrubs from physical decay,but also controls plant diseases and pest insects efficiently,especially the damage caused by trunk borers. In order to promote further research and application on management of plant diseases and pest insects by means of stumping,status quo of stumping of several sand-fixing shrubs and control of trunk borers by stumping were summarized in the paper.
