摘　　要：通过盆栽实验和田间小区实验,研究有机硅助剂对烟嘧磺隆的增效作用。结果表明,烟嘧磺隆加入有机硅助剂后增效作用明显,特别是对于阔叶杂草防效增效显著;不同有机硅助剂对烟嘧磺隆的增效作用相当;烟嘧磺隆施药剂量40a.i.g/hm2,加入质量分数为0.1%的有机硅助剂ss3#后对杂草防效与烟嘧磺隆施药剂量60a.i.g/hm2防效相当;添加有机硅助剂能够降低烟嘧磺隆用药量及用水量。Pot experiments and field experiments were conducted with organosilicone surfactants to determine weed control effect of nicosulfuron.The results showed that applying with organosilicone surfactants can provide a dramatic increase in weed control effect,especially on broadleaf weed.Different band of organosilicone surfactants had insignificant variance on weed control effect.Nicosulfuron at 40 a.i.g/hm^2,applied ss3#with 0.1% of spray volume,was similar to the control effect of nicosulfuron at 60a.i.g/hm^2.It indicated that application of organosilicone surfactant could significantly reduce dosage of nicosulfuron and water consumption.
