| 中文摘要: |
| 在大田条件下，以合丰50和垦农4号大豆(Glycine max)为材料，研究了在V3期叶面喷施DTA-6、S3307和TIBA三种植物生长调节剂对大豆氮代谢相关指标及产量品质的影响。结果表明，V3期叶喷TIBA、S3307和DTA-6提高了大豆NR活性，提高了全氮、可溶性蛋白、NO3- N和游离氨基酸含量，增强了叶片合成能力，促进大豆生殖生长阶段叶片的氮代谢；V3期叶喷TIBA、S3307和DTA-6能够有效提高大豆的产量，而S3307和DTA-6对大豆蛋脂总量也有一定的促进作用。三种植物生长调节剂对氮代谢和产量品质的综合调控效果为S3307＞DTA-6＞TIBA＞CK。 |

| In the field planting conditions, The experiments researched the effects of three plant growth regulators（PGRs） of TIBA,S3307 and DTA on nitrogen metabo
lism related indicators, yield and quality in soybean by spaying in V3 stage. ‘Hefeng50’ and ‘Kennong4’(Glycine max (L.) Merr.), were selected as the experimental materials. The results showed that：The S3307 and DTA-6 increased the activity of Nitrate reductase in soybean leaves by spaying in V3 stage ，increased synthesis of NO3- N and; but the effect was not signigicant to flowers； PGRs decreased abscission cellulose activity in pod and abscission pod
by spaying at R3 stage, the regulation effect of TIBA was the best. Analysis showed that：The plant growth regulators decreased abscission cellulase activity, promoted flowers and pods development of soybean at V3、R1 and R3 stages, Conducive to increasing production. The comprehensive regulation effect is S3307＞DTA-6＞CK＞TIBA. |
