摘要
为了探索稻瘟酰胺与氨基寡糖素配施对水稻防病、增产的效果,研究以两优2118为材料,开展了喷施不同剂量的稻瘟酰胺、稻瘟酰胺+不同剂量的氨基寡糖素配合施用的水稻田间抗病试验。结果表明:稻瘟酰胺与氨基寡糖素配施能显著提高水稻叶瘟、穗颈瘟及纹枯病的防治效果,增加水稻的千粒重,与施用高剂量稻瘟酰胺相比在水稻病害防治效果、增产率方面无明显差异。稻瘟酰胺与氨基寡糖素的配合施用有利于降低有机化合物的使用,符合当前绿色农业、农药减量的趋势,建议推广。
In order to explore the effect of combined application of fenoxanil and amino-oligosaccharins on rice disease resistences and yield increase,the rice cultivar Liangyou 2118 was used as material to carry out the field disease resistance test with different dosages of fenoxanil and fenoxanil+amino-oligosaccharins.The results show that the combined application of fenoxanil and amino-oligosaccharins can significantly improve the control effect of rice leaf blast,neck blast and sheath blight,and increase 1000-grain weight,which has no significant difference in rice disease control effect and yield increase rate in comparison to the single application of high-dose fenoxanil.The combined application of fenoxanil and amino-oligosaccharins is beneficial to reducing the use of organic compounds,which is in line with the current trend of green agriculture and pesticide reduction,so it is recommended to promotion.
