2.3.5—三碘苯甲酸(简称TIBA)是一种生长调节剂,对大豆有矮化壮秆、增花增荚、促进早熟的作用。根据大豆的生物学特性,大豆植株生长点形成的激素有利于促进植株茎叶的生长,抑制花荚的发育。在正常情况下,由于大部分能量用于营养体生长,籽实产量不高。在肥水充足条件下,往往造成营养生长过盛,招致早期郁闭倒伏。而2.3.5—三碘苯甲酸则可抑制生长点中激素的流动,解除激素作用,有利于花荚形成,因而可以促使大豆增产。
2.3.5 - triiodobenzoic acid (referred to as TIBA) is a growth regulator, dwarf strong stalks on soybean, increased flower pods, and promote early maturity. According to the biological characteristics of soybean, the growth of soybean plant hormone point is conducive to promoting the growth of plant stems and leaves, inhibiting flower pod development. Under normal conditions, seed yield is not high because most of the energy is used for vegetative growth. Adequate conditions in the fertilizer and water, often resulting in excessive vegetative growth, leading to early lodging depression. However, 2.3.5-triiodobenzoic acid can inhibit the growth of hormone in the growth of the flow, the elimination of hormones, is conducive to the formation of flower pods, which can promote soybean yield.
