摘　　要：试验应用 3个大豆品种经 3年研究 ,探讨了新型植物生长调节剂SHK 6对大豆产量与品质协同提高的效应及生理基础。结果表明 :1)SHK 6处理增强植株抗倒伏能力 ,同时明显提高了大豆产量 ,产量增幅可达到 2 9%～ 4 2 % ,改善了大豆产量构成因素 ;2 )SHK 6处理提高了籽粒蛋白质含量 ,其质量分数为 2 84 %～ 10 2 8% ,且改善了氨基酸组分 (除中黄 17外 ) ,例如必需氨基酸质量分数提高了 4 15 %～ 8 39% ,氨基酸总量增加了 4 84 %～6 6 5 % ;3)SHK 6处理显著提高了大豆根系对氮素的吸收、转化和向地上部运输 (伤流 )的能力 。Field experiments were conducted in 1999 to 2001 at the Research Center of China Agricultural University to examine the effect of PGR SHK-6 on soybean yield and quality. Sequential applications of SHK-6 were used for all experiments. Seeds were treated with SHK-6 at 0.4?mL·kg -1 seeds and spray applications in branching stage in 1999 to 2001 at 75?mL·hm -2 . The results were showed: 1) SHK-6 treatments increased 29% to 42% seed yields than the control and the yield-components were improved by SHK-6 treatment. 2) SHK-6 treatments increased 2.84% to 10.28% protein content in grains, and also improved 4.15% to 8.39% necessary amino acids and 4.84% to 6.65% total amino acids than the control, except for Zhonghuang 17. 3) The ability of root absorbed and transformed nitrogen was significantly increased by SHK-6 treatments, and also the ability of leaves reduced and transformed nitrogen was improved by SHK-6 treatments.
