摘　　要：叶面喷施硒肥是作物富硒的重要途径。以小冰麦33为试验材料,采用随机区组试验的方法,研究了孕穗期叶面喷施0、50、100 g/hm^2的亚硒酸钠以及6 g/L的有机硒肥对春小麦产量、农学性状、物质积累与分配以及籽粒硒富集能力的影响。结果表明,低浓度(50 g/hm^2)亚硒酸钠以及有机硒喷施显著提高了春小麦的生物量、千粒重以及籽粒Se浓度,而喷施高浓度(100 g/hm^2)的亚硒酸钠则对春小麦的生长表现出一定的抑制作用。但不同浓度和类型硒肥施用,均显著提高了籽粒Se浓度(0.17~0.885 mg/kg),且在安全富硒标准范围内。综上,吉林省中部地区春小麦孕穗期叶面喷施亚硒酸钠推荐用量为50 g/hm^2。Spraying foliar selenium fertilizer is an important way to enrich selenium in crops. The effects of foliar spraying of 0,50,100 g/ha sodium selenite and 6 g/L organic selenium(O-Se)fertilizer at booting stage on yield,agronomic characteristics,dry matter accumulation and distribution,and selenium enrichment ability of spring wheat were determined,and the experiment were used by randomized block design. The results showed that low concentration of sodium selenite(50 g/ha)and organic selenium could significantly increase the yield,biomass,1000-grain weight and grain Se concentration of spring wheat,while spraying with high concentration(100 g/ha)of sodium selenite inhibited the growth in spring wheat. However,the concentration of Se in grains ranged by 0.17~0.885 mg/kg with different concentrations and types of selenium fertilizers,which were all within the safe selenium enrichment standard. The recommended dosage of sodium selenite sprayed on spring wheat leaves at booting stage in central Jilin Province is 50 g/ha.
