摘　　要：为提高绿豆产量,解决绿豆生产问题,以绿丰2号为试验材料,用6个浓度的烯效唑浸种,研究烯效唑对绿豆生长及苗期生理指标的影响,筛选出较适宜的3个浓度对3个绿豆品种进行田间试验,探究烯效唑浸种对绿豆生育期、根系、生长指标和产量的影响。结果发现,40 mg·L^(-1)的烯效唑浸种最为适宜,烯效唑浸种可以显著降低绿豆的株高,3个适宜浓度下株高平均降幅为6.3%、13.2%和18.6%;显著增加绿豆根重,3个适宜浓度下根重平均增加16.9%、34.4%和30.5%。烯效唑20和40 mg·L^(-1)处理能显著增加绿豆产量,产量平均增加7.1%和11.7%;并能增加绿豆的分枝、荚数、单株粒重、单株重、根长及侧根数;提高苗期保护酶(SOD和POD)的活性和叶绿素含量,减少MDA含量。In order to improve the yield of mung beans and solve the problem of mung bean production,mung beans were used as experimental materials.Six concentrations of uniconazole were soaked in seeds to study the effects of uniconazole on the growth and physiological indicators of mung beans during the seedling stage.Three suitable concentrations were selected for field experiments on three mung bean varieties to explore the effects of uniconazole soaking on the growth period,root system,growth indicators,and yield of mung beans.The results showed that soaking seeds with 40 mg·L^(-1)of uniconazole was the most suitable;Soaking seeds with uniconazole could significantly reduce the plant height of mung beans,with an average decrease of 6.3%,13.2%and 18.6%under three treatment concentrations;Significantly increased the root weight of mung beans,with an average increase of 16.9%,34.4%and 30.5%under three treatment concentrations;Treatment with 20 and 40 mg·L^(-1)of uniconazole significantly increased yield,with an average increase of 7.1%and 11.7%;And it could increase the branching,pod number,single plant grain weight,single plant weight,root length,and lateral root number of mung beans;Improve the activity of protective enzymes(SOD and POD)and chlorophyll content during the seedling stage,and reduce MDA content.
