杂草是影响甜菜生长的主要因素之一,为了探讨化学除草剂对甜菜田禾本科杂草的防效,我们于2003年进行了此项试验,以掌握其适宜的用量、防除效果及对甜菜的安全性,为大面积推广应用提供依据。 1 试验材料试验药剂:10.8%高效盖草能乳油,5%精禾草克乳油,15%精稳杀得乳油,6.9%威霸浓乳剂。喷雾器械:背负式工农16型喷雾器。 2 试验方法 Weeds are one of the main factors affecting the growth of sugar beet. In order to investigate the control effect of chemical herbicides on grass weeds in beet fields, we conducted this experiment in 2003 to understand its proper dosage, Safety, provide the basis for large-scale popularization and application. A test material Test drugs: 10.8% high cover grass can EC, 5% fine grass EC, 15% fine kill emulsifiable concentrate, 6.9% Wei Pa concentrated emulsion. Spraying equipment: Knapsack worker-peasant type 16 sprayer. 2 test methods
