PP_(333)是一种新的植物生长延缓剂。1981年后,国外始有PP_(333)矮化果树、作物及观赏植物的报道,但迄今尚未推广。国内仅见到两篇PP_(333)的综述,尚无实验报告。因此,我们研究了PP_(333)在13种主要农作物和蔬菜中的生物学效应及其应用范围。
PP 333 is a new plant growth retardant. Since 1981, there have been reports of dwarfing fruit trees, crops and ornamental plants in foreign countries since PP_ (333), but so far they have not been popularized. There are only two reviews of PP_ (333) in China and no experimental report yet. Therefore, we studied the biological effects of PP 333 and its application in 13 major crops and vegetables.
