化学除草剂在林业上的应用

使用果尔，禾纳斯，丁草胺和克芜踪等10余种除草剂，对浙江省的圃地，草坪，地被及林地等的化学除草进行了应用研究。研究结果表明：化学除草剂种类多，效用不同，应依不同目的有选择地合理运用，几种除草剂合用效果更好，如把果尔，禾纳斯和丁草胺分别加入克芜踪，除草效果均优于其单一使用，除草率都在91％以上，化学作草明显省工省成本，只是不同植物类型的区域，节省的成本多少不同，在实行化学除草时，各种植物对药物的敏感性不一样，绝大部分除草剂都能保护主体植物而杀灭杂草，但如果施用量不当，会产生药害，表6参8

Application of chemical herbicides in forestry

Studies were carried out on application of more than 10 kinds of herbicides such as Gaol,Acetochlor,Butylochlor,Paraguat and Sulfometuron methyl in nursery garden,lawn and forest land.chemical herbicides should be rationally selected and applied,according to the different purpose of weed control.Herbicides,which were mixed to be applied,would make a better weed control effect.For example,if Gaol,Acetochlor,Butylochlor was added to Paraguat,respectively,the weed control effect would be better than using individually,and weed control rates were more than 91%.The sensibility of most plants is different to herbicides,so most of the herbicides can kill weed,and protect the goal plants.However,irrational application of herbicides could make goal plants to be damaged.
