Has established the Avey rhzomorph through the field test remains the analysis method in the sea cabbage and the soil, and remained to it in the sea cabbage and the soil has carried on the determination, the sample with the methyl cyanide extraction, after extracting the revolving concentration nearly did, with the few methyl cyanides dissolves, passed through PRS the solid phase extract (SPE) column to purify again, eluent air-dried after the nitrogen with the nitrogen methyl imidazole and the trifluoroacetic acid bitter wine grows, the derivative with the highly effective liquid chromatography analysis, used the external standard legal quantity. In the increase density 0.05, 0.5mgkg-1 scope, the sea cabbage average increase returns-ratio is 85.1%~93.3%, the coefficient of variation is 5.39%~12.05%; The soil average increase returns-ratio is 90.9%~98.5, the coefficient of variation is 1.10%~6.30%. Picks out limits is lowly for 5μgkg -1. The Avey rhzomorph derivative assumes the goo
