- 摘要:
- 以“贡选1号”为试材,研究了不同时期喷施烯效唑、多效唑、豆歌、矮壮素、缩节胺等植物生长调节剂对套作大豆形态及产量的影响。结果表明:调节剂处理后植株株高降低,以分枝期喷施150 mgL-1多效唑效果极显著;茎秆增粗,以分枝期喷施100 mg L-1烯效唑效果显著;分枝数增加。单株荚数、百粒重增加,二者均以分枝期喷施100 mgL-1烯效唑效果极显著。调节剂处理后产量增加显著,以分枝期喷施100 mgL-1烯效唑效果最佳,较对照增产77.6%。结果表明:在改善大豆株型、提高产量方面,均以分枝期喷施100 mgL-1烯效唑效果最优。
- Abstract:
- The effect of spraying growth regulator on morphology and yield of relay cropping soybean was studied under the wheat/maize/soybean relay cropping system.In this experiment the plant was treated by different kinds of growth regulator at branching and initial blooming stage.The results showed that growth regulator could significantly reduce plant height,increase branch number,enhance stem diameter,and could significantly improve yield by increasing pod number per plant and seed weight,and yield increased by 77.6 % when spraying 100 mgL-1 S-3307 at branching stage.Results suggest that the effect of spraying 100 mgL-1S-3307 at branching stage was best in improving plant morphology and yield.
