我县有油茶林面积26.8万亩,常年垦抚面积10余万亩。在这些油茶林中,杂草灌木丛生,严重影响了油茶生长。为此,1983—1984年我们试用草甘膦防除油茶林杂草,结果如下: 处理 10％草甘膦水剂(广西南宁市化工实验厂)1、1.5、2斤各加水100斤(再另加0.1％合成洗衣粉做湿润剂)及对照4个处理,每处理面积为1亩。供试林地系县油茶科学研究所及太子庙乡汪家冲油茶林。1983、1984年8月8日(晴天)用喷雾器喷雾、对照喷清水。各小区每次调查1平方尺,然后统计杂草死亡情况。 试验结果 1.地上部分:药后7天观察,各处理地上部的多年生白茅,香附子和1年生的竹叶草、地毯草等,叶片均开始发黄,尤以1.5％浓度的为多,达95％以上,并有30％左右叶

To this end, 1983-1984, we try glyphosate control weeds Camellia weeds, the results are as follows: 10% glyphosate treatment agent (Guangxi Nanning Chemical Laboratory) 1,1.5,2 kg each add 100 pounds (another Add 0.1% synthetic detergent as humectant) and control 4 treatment, each treatment area of 1 acre. For the Department of Forest County Camellia Institute of Science and Prince Edward Temple Township Wang Chong tea tree tea. 1983, August 8, 1984 (sunny) spray with a spray, the control spray water. Each plot survey 1 square feet, and then statistics weed deaths. Test results 1.
