摘　　要：为促进中微量元素肥料的合理使用,本研究针对黑龙江省黑河地区的土壤状况,使用铁、锰、钼、硼及镁肥处理种子,分析中微量元素肥料对大豆出苗、株高、干物质积累、叶面积、叶绿素含量、产量及产量构成因子的影响。结果表明:供试的铁、锰、钼、硼及镁肥对大豆的出苗无不良影响,对分枝和荚数无影响,各处理的干物质积累量、叶面积及叶绿素含量均较CK增加,差异不显著。钼肥和硼肥较CK增产7.4%、5.3%,达到显著水平;镁肥和锰肥较CK增产11.8%、10.0%,达到极显著水平。In order to promote the rational use of medium and trace element fertilizers,this study used iron,manganese,molybdenum,boron and magnesium fertilizers to treat seeds based on the soil conditions in Heihe area of Heilongjiang Province,and analyzed the effects of medium and trace element fertilizers on soybean seedling emergence,plant height and dry matter accumulation,leaf area,chlorophyll content,yield and yield component factors.The results showed that the tested iron,manganese,molybdenum,boron and magnesium fertilizers had no adverse effect on the emergence of soybeans,and no effect on the number of branches and pods.The dry matter accumulation,leaf area and chlorophyll content of each treatment were all increased compared with CK,no obviously different.Compared with CK,molybdenum fertilizer and boron fertilizer increased production by 7.4%and 5.3%,reaching a significant level compared with CK;magnesium fertilizer and manganese fertilizer increased production by 11.8%and 10.0%compared with CK,reaching a very significant level.
