[Method]Effects of spraying periods,different concentrations and spraying times of fenaminosulf on yield and output value of single cropping Z. latifolia were studied.[Result]In some regions where single cropping Z. latifolia could be harvested twice per year,fenaminosulf significantly promoted formation of swollen gall,and advanced the harvest period for about 50 d. Application of 0.5 g/L（ a.i.） fenaminosulf at 150,160 and 175 d post transplanting promoted swollen gall formation and enhanced the yield of Z. latifolia.In normal single cropping Z. latifolia growing regions,once application of fenaminosulf obviously advanced harvest period and improved yield and benefit of Z. latifolia,but with the increasing frequency of use,yield and benefit of Z. latifolia decreased significantly.[Conclusion]It is recommended that 1.0 g/L（a.i.） fenaminosulf can be applied for just once at 40-60 d post transplanting of Z. latifolia.展开更多
