Abstract: Screenings of chemical herbicides to eliminate weeds in forests have been conducted in the nurseries,young stands,planting sites and fire preventing lines.In the Pine and Fir nurseries,Goal or Nitrophen was used to kill the weeds with an effect of over 90%;Pines,Firs,broa-dleaf trees and fruit trees,which are high than 1 m,were treated with leaf or needle spray of Glyphosate with an effect of over 85%;on the planting sites,leaf surface sprays of Glyphosate,2,4-DA,Glyphosate+Fosamine or Velpar+Glyphosate were treated to kill weeds and shrubs with an effect of 95%;on fire preventing lines,Glyphosate+Forsamine or Glyphosate+Velpar would achieve good results.
