多效唑在我州杂稻制种上,已广泛应用于母本育秧和调节父母本花期,具有矮化秧苗,增蘖、增叶、提高秧苗素质,抑制幼苗发育,促进父母本花期相遇的效应,成为杂稻高产制种的主要技术措施之一。探讨其在杂稻制种上的适宜施用浓度,对进一步提高杂稻制种产量有不可低估的现实意义。现就近年收集到的试验资料整理分析于后。
Paclobutrazol has been widely used in hybrid rice seed production in our country and has been widely used in female parent seedling and parental flowering. It has the effects of dwarfing seedling, increasing tillering, increasing leaf quality, improving seedling quality, restraining seedling development and promoting parents’ Become hybrid rice high-yielding seed production of one of the major technical measures. To explore its appropriate application of hybrid rice seed production concentration, to further improve the hybrid rice seed production can not be underestimated the practical significance. Now collected in recent years, after the test data analysis.
