摘要: 以国豪油8号为试验材料,研究在油菜(Brassica napus L.)蕾薹期喷施不同浓度多效唑的效果。结果表明,油菜喷施多效唑既能培育壮苗、改善株型结构和产量性状,又能有效解决油菜倒伏问题。国豪油8号在蕾薹期喷施15%多效唑可湿性粉剂1 500 g/hm2可以增加单株有效角果数、每角粒数、千粒重和产量。

关键词: 油菜(Brassica napus L.), 多效唑, 浓度, 蕾薹期, 经济性状, 产量

Abstract: Using Guohaoyou No.8 as a test material,the effect of spraying paclobutrazol at different concentrations during the rape (Brassica napus L.) bud period was studied.The results showed that rapeseed could not only cultivate strong seedlings,improve plant type structure and yield characteristics,but also effectively solve the problem of rape lodging when spraying paclobutrazolin.The number of carob fruits per plant,the number of grains per grain,the weight of the rapeseed,and yield of Guohaoyou No.8 was increased by spraying with 1 500 grams of 15% paclobutrazol wettable powder per hectare during the bud period.

Key words: rape (Brassica napus L.), paclobutrazol, concentration, stem elongation period, economic traits, yield
