摘　　要：以晚熟大豆品种贡选1号为材料,研究了烯效唑干拌种对大豆生长过程中的主要形态特征和产量的效应。结果表明:干拌种处理降低了株高,增加茎粗,缩短主茎长,增加了叶片数和分枝数,提高了叶片SPAD、叶面积指数和干物质积累,最终通过增加单株有效荚数提高了产量,以3.2mg/kg浓度拌种的增产作用最大。The effect of uniconazole on morphological characteristics and powder for dry seed treatment yield of soybean （Glycine max studied. The results showed that the uniconazole treatments yield. Uniconazole treatment could decrease the plant height stem diameter, leaf number, branch number, SPAD value, LAI through increasing the pod number per plant. The best yield mg/kg. with different concentrations （L.） ,cv. Gongxuan 1）were could significantly improve soybean and main stem length, and increase and UDM, and finally improve yield effect was the concentration of 3. 2mg/kg.
