植物生长调节剂在培养壮苗、提高移栽成活率、延长保存时间等方面都取得了很好的应用效果。ABT增产灵和土菌消(化学名称为3—羟基—5—甲基异噁唑,简称HMI)是两种新型的植物生长调节剂,在适宜的浓度下对多种作物的生长有促进作用。如提高发芽率,加速幼苗生长,增加禾本科作物的 Plant growth regulators in the cultivation of strong seedlings, improve the survival rate of transplanting, prolonging the preservation time have achieved good results. ABT Zeng Ling and soil bacteria eliminate (chemical name for 3-hydroxy-5-methyl isoxazole, referred to as HMI) are two new plant growth regulators, in the appropriate concentration of a variety of crops to promote the role of growth . Such as increasing the germination rate, speed up seedling growth, increase the grass crop
