摘要:
于2010和2011年采用0、50、100、150、200、250、300、350 mg·kg-18个多效唑浓度对6片复叶期的晋遗31大豆进行叶面喷施。结果表明,50～350 mg·kg-1多效唑处理均表现增产，增产幅度2.22%～21.97%。其中以200 mg·kg-1产量最高（4 175.40 kg·hm-2）。喷施多效唑后大豆株高和结荚高度明显降低,分枝增多,节间距缩短,百粒重、总荚数、单株重和单株粒重明显增加。综合分析，6片复叶期叶片喷施200 mg·kg-1多效唑能够有效改善农艺性状并提高大豆产量。
Abstract:
In this study,soybean cv.Jinyi31 were leaf sprayed with 0,50,100,150,200,250,300 and 350 mg·kg-1 Paclobutrazol respectively at V6 in 2010 and 2011. Soybean yield increased from 2.22% to 21.97% under 50-350 mg·kg-1 Paclobutrazol,and the highest yield of 4175.40 kg·ha-1was obtained under 200 mg·kg-1 Paclobutrazol.Leaf spraying Paclobutrazol decreased podding height and plant height,shortened internode length,increased branches,pods and seed weight.Results suggest that 200 mg·kg-1 is optimal Paclobutrazol concentration for ameliorating agronomic traits agronomic and improving yield of soybean.
