摘　　要：为明确不同有机硒肥对毛豆植株生长和富硒效果的影响,采用大田试验的方式在毛豆开花期和结荚中后期以叶面喷施的方式施用液体有机纳米硒肥和有机螯合硒肥,分析毛豆植株生长、产量构成和毛豆果实硒含量。结果表明,叶面喷施2种有机硒肥均显著提高了毛豆分枝期、结荚期和成熟期的株高,喷施有机纳米硒显著降低了成熟期毛豆叶片SPAD值,喷施有机螯合硒显著增加了结荚期毛豆叶片SPAD;喷施有机纳米硒能够显著增加毛豆产量,喷施有机螯合硒显著降低了豆粒数、荚粒数、豆粒重等产量构成因素,同时也显著降低产量;喷施有机纳米硒后毛豆果实硒含量为0.45 mg/kg;喷施有机螯合硒后毛豆果实硒含量为0.26 mg/kg。综上,叶面喷施有机硒肥是增加毛豆果实中硒含量的有效技术手段,喷施相同硒浓度下,有机纳米硒对毛豆植株和富硒的有益作用优于有机螯合硒。In order to clarify the effects of different organic selenium fertilizers on the plant growth and selenium enrichment of soybeans,liquid organic nano selenium fertilizer and organic chelated selenium fertilizer were applied by foliar spraying at the flowering stage and the middle and late pod setting stage of soybeans,and the plant production,yield composition and selenium content of soybeans were analyzed.Results showed that foliar spraying of two kinds of organic selenium fertilizer significantly increased the plant height of soybean at branching stage,pod setting stage and mature stage,spraying of organic nano selenium significantly decreased the SPAD value of soybean leaves at mature stage,and spraying of organic chelated selenium significantly increased the SPAD of soybean leaves at pod setting stage.Spraying organic nano selenium could significantly increase the yield of soybeans.Spraying organic chelated selenium significantly reduced the yield components such as the number of beans,the number of pods and the weight of beans,and also significantly reduced the yield.After spraying organic nano selenium,the selenium content of soybean fruit was 0.45 mg/kg;after spraying organic chelated selenium,the selenium content of soybean fruit was 0.26 mg/kg.In conclusion,foliar spraying of organic selenium fertilizer was an effective technical means to increase the selenium content in soybean fruits.Under the same selenium concentration,the beneficial effect of organic nano selenium on soybean plants and selenium enrichment was better than organic chelated selenium.
