摘要
果尔（Ｏｘｙｆｌｕｏｒｆｅｎ）为森林苗圃优良除草剂，苗床剂量６００ｍｌ／ｈｍ２（２３．５％乳油），６０天内除草效果达９０％～９６％；出苗后喷施果尔３００ｍｌ／ｈｍ２混合盖草能（Ｈａｌｏｘｙｆｏｐ）（１２．５％乳油）３００ｍｌ／ｈｍ２，除草效果更佳．氟乐灵（Ｆｒｉｆｕｒａｌｉｎ）对针叶树园地，苗期用量２２５０ｍｌ／ｈｍ２（４８％乳油）除草效果达８７％～９８％，但施药后需洗苗，并复盖０．５～１．０ｃｍ的红心土对苗木安全，其残效期可达４个月左右．乙草胺（Ａｃｅｔｏｃｈｌｏｒ）防除单子叶杂草有特效，是阔叶树种苗圃的良好除草剂．除草剂使用方法简便，一般采用药土或常规喷雾施药，除草效果好，经济效益显著．
In order to effectively controll the growth of weeds in the nursery,and to provide enough seedlings of higher gualitg for plantation,we have selected a few new types of forestry chemical harbicide Oxyfluorfen、Frifurlin、Acetochlor and Haloxyfop to ged rid of the weeds by experiments The results Showed that the efficiency of four chemical herbicide are quite satisfying, 87 to 98 percent of the weeds were killed.
