野燕枯是一种内吸型除草剂,对野燕麦有较好的防除效果。但野燕麦发生面积大,出苗不整齐,最佳防治时期短,采用人工或拖拉机地面喷雾,难以在短时间内进行大面积防除。为此,我们于1986年进行了飞机喷洒野燕枯防除野燕麦试验。 试验在乌鲁木齐市西郊一○四团三连冬麦田(八农7416)进行,供试药剂为40％野燕枯水剂(西北大学陕西武功化工厂产),用国产运五型飞机悬挂GP-81型喷液设备喷施, Wild Yan dry is a systemic herbicide, has good control of wild oats. However, wild oats occurred in large areas, irregular emergence, the best control period is short, the use of artificial or tractor ground spray, it is difficult in a short period of large-scale control. To this end, we carried out the wild-weed control of wild oat in 1986. The experiment was carried out in the 104th winter wheat field of Sanlian Sanlian (Baonong 7416) in the western suburbs of Urumqi. The test agent was 40% wild yam (produced by Shaanxi Wugong Chemical Plant of Northwest University) -81 spray equipment spraying,
