摘　　要：为有效防治番茄上的烟草花叶病毒,开展70%褐藻双寡糖粉剂和7%褐藻双寡糖水剂不同施用量对番茄的抗病毒效果研究。结果表明,70%褐藻双寡糖粉剂和7%褐藻双寡糖水剂均能显著降低番茄病毒病发病率,促进番茄生长,整体上70%褐藻双寡糖粉剂的抗病效果优于7%褐藻双寡糖水剂。与常规施肥用药相比,常规施肥减药30%+70%褐藻双寡糖粉剂500倍液处理番茄病毒病发病率降低56.67个百分点,单株果数增加了77.42%,效果最好。In order to effectively control the tobacco mosaic virus in tomato,the antiviral effects of different dosages of 70% brown algae oligosaccharide powder and 7% brown algae oligosaccharide aqueous solution on tomato were studied.The results showed that both 70% brown algae oligosaccharide powder and 7%brown algae oligosaccharide aqueous solution could significantly reduce the incidence of tomato virus disease and promote tomato growth.On the whole,the disease resistance effect of 70% brown algae oligosaccharide powder was better than that of 7% brown algae oligosaccharide aqueous solution.Compared with conventional fertilization and pesticide,the incidence of tomato virus disease treated with conventional fertilization and pesticide reduced 30%+70% brown algae oligosaccharide powder 500 times dilution decreased by 56.67 percentage points and increased the number of fruit per plant by 77.42%.
