Abstract：Adopting field test method and taking broccoli cultivar‘ Naihanyouxiu’ as test material，this paper studied the effects of foliar spraying 2 selenium fertilizers with different concentrations on the contents of glucosinolate and selenium in broccoli．Among of them，the concentrations of selenium fertilizer‘Fuxibao’were set to 12.0，9.6，8.0，6.9，6.0，0（CK）mg · L-1，concentrations of the other fertilizer ‘Highconcentrated Organic-selenium Fertilizer’ were set to 2.5，2.3，2.1，1.9，1.8，0（CK）mg · L-1．The results showed that the total glucosinolate contents of broccoli treated with 6.0 mg · L-1 ‘ Fuxibao’ and 2.3 mg ·L-1 ‘ High-concentrated Organic-selenium Fertilizer’ were the highest，being 13.72 and 15.38 μmol · g-1，respectively，increased by 5.86% and 18.67% comparing with their corresponding controls．The differences had all reached a significant level．Treatments of 9.6 mg · L-1 ‘ Fuxibao’and 2.3 mg · L-1 ‘ High-concentrated Organic-selenium Fertilizer’ had obtained the highest selenium contents in broccoli，being 0.811 3 and 1.776 7 mg · kg-1，respectively，reaching 3.52 and 7.74 times of their corresponding controls，respectively．The differences were also reaching a significant level，indicating both selenium fertilizers could effectively increase the glucosinolate contents and selenium contents in broccoli．Meanwhile，the total glucosinolate contents and beneficial glucosinolate（RAA，4OH，GBC，4ME，NEO）contents of broccoli treated with 2.3 mg · L-1 ‘High-concentrated Organic-selenium Fertilizer’ were higher than that treated with 6.0 mg · L-1 ‘ Fuxibao’，
indicating 2.3 mg · L-1 ‘High-concentrated Organic-selenium Fertilizer’had better effects on improving．
