生长调节剂在大豆上的应用已有多年,有一定的增产效果。以往的研究工作大多侧重于产量及部分机理,诸如促使植株矮化、加速养分运转等方面。本文就生长调节剂对大豆产量及种子品质的影响,以及对叶片生长、茎节生长、物质运输等做探讨,以期有助于正确而合理地施用生长调节剂。 早在1965年Anderson等将2,3,5-三碘苯甲酸(TIBA)应用于田间。结果表明在大豆开花期喷施TIBA,使无限结荚型的大豆植株矮化,倒伏现象减轻,早熟,多荚 Growth regulators in soybean has been used for many years, a certain increase in yield. Much of the research work in the past focused on yield and some mechanisms such as dwarfing plants and accelerating nutrient operation. In this paper, the effects of growth regulators on soybean yield and seed quality, as well as on the growth of leaves, stems growth, material transport and so on, in order to help the correct and reasonable application of growth regulators. As early as 1965 Anderson et al. Used 2,3,5-triiodobenzoic acid (TIBA) in the field. The results showed that the spraying of TIBA at the flowering stage of soybean dwarfed the soybean plant with unlimited pods and the lodging phenomenon reduced,
