[ Objective] The reference for the high-yielding peanut cultivation was provided through the research on the effect of 4 kinds of plant growth regulators on its yield and related trait. [ Method ] 4 kinds of plant growth regulators: Chaoshengban (there were two treatments and once spraying:900 g/hm2 in the flower-needling period;twice sprayings:450 g/hm2 in seedling period and 900 g/hm2 in the flower-needling period),and Guoguangaifeng(paclobutrazol · mepiquat chloride WP) of 2 250 g/hm2 ,Kuailvfeng of 1800 g/hm2 and Lilibao of 1125 g/hm2 in the flowerneedling period of peanut were sprayed ,respectively ,and the clean water as CK was sprayed. The effect of every treatments on peanut yield and its related trait was analyzed[ Results］ It was safety to spray the plant growth regulator in peanut production and 9. 32％ of peanut yield was raised in the treatment of Chanshengbao-spraying ;4.24％, in both Guoguangaifeng and Kuailvfeng-spraying ;0.42％,in Lilibao-spraying, compared with that in CK. [ Conclusion ] The plant growth regulators-Chaoshengbao should be preferred in peanut production.%[目的]研究4种植物生长调节剂对花生产量及相关性状的影响,为花生高产栽培提供参考.[方法]在花生开花下针期,以喷清水为对照,分别喷施几种不同的植物生长调节剂,即喷施花生超生宝1次(开花下针期900g/hm2)、花生超生宝2次(苗期450g/hm2和开花下针期900g/hm2)、国光矮丰(多唑·甲哌鎓可湿性粉剂)2250g/hm2、快绿丰1800g/hm2,花生控旺粒粒饱1125g/hm2,调查分析各处理对花生产量及相关性状的影响.[结果]喷施植物生长调节剂对花生生产安全,其中喷施花生超生宝的处理较清水对照增产9.32%,喷施国光矮丰(多唑·甲派鎓可湿性粉剂)和快绿丰的处理均增产4.24%,喷施花生粒粒饱的处理增产0.42%.[结论]花生生产应首选花生超生宝作为调节剂.
