摘　　要：采用大田试验方法,以青花菜品种耐寒优秀为试材,研究叶面喷施两种不同浓度硒肥对青花菜中硫代葡萄糖苷(硫苷)和硒含量的影响,其中富硒宝浓度设置为12.0、9.6、8.0、6.9、6.0、0(CK)mg·L^(-1),高浓缩有机硒肥浓度设置为2.5、2.3、2.1、1.9、1.8、0(CK)mg·L^(-1)。结果表明:6.0 mg·L^(-1)富硒宝、2.3 mg·L^(-1)高浓缩有机硒肥处理的青花菜总硫苷含量最高,分别为13.72、15.38μmol·g^(-1),比对照分别提高了5.86%、18.67%,差异均达显著水平;9.6 mg·L^(-1)富硒宝、2.3 mg·L^(-1)高浓缩有机硒肥处理的青花菜硒含量最高,分别为0.8113、1.7767 mg·kg^(-1),分别是对照的3.52、7.74倍,差异亦均达显著水平,表明这两种硒肥均可有效提高青花菜的硫苷和硒含量。同时,2.3 mg·L^(-1)高浓缩有机硒肥处理的青花菜总硫苷和有益硫苷(RAA、4OH、GBC、4ME、NEO)含量均高于6.0 mg·L^(-1)富硒宝处理,表明2.3 mg·L^(-1)高浓缩有机硒肥的效果更佳。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 15.38μmol·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 0.8113 and 1.7767 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.
