摘　　要：为明确不同植物生长调节剂对连作大豆产量及其相关性状的影响,2022-2023年以农庆豆28为材料,在连作5年大豆的试验地上,采用随机区组设计,于大豆分枝期喷施缩节胺、烯效唑、矮壮素、玉黄金、吨田宝、壳聚糖6种植物生长调节剂,分析不同调节剂对连作大豆生理性状、农艺性状、产量、品质的影响。结果表明:吨田宝、玉黄金、烯效唑、壳聚糖等4种调节剂显著增加产量,两年的增产幅度分别为5.55%~10.3%和1.95%~11.59%,由高到低依次为壳聚糖>烯效唑>玉黄金>吨田宝。此外,吨田宝、玉黄金、烯效唑、壳聚糖4种生长调节剂的施用增加了大豆叶绿素、可溶性糖、可溶性蛋白含量,并且降低了株高,增加了单株荚数、单株粒数和百粒重。To improve quality and efficiency of continuous soybean cultivation through chemical control,effects of plant growth regulators on yield and traits of continuous cropping soybeans were studied.Nongqingdou 28 was used as material from 2022 to 2023.On the continuously 5-year-soybean planted experimental site,a randomized block design was conducted for plant growth regulators test.Six plant growth regulators were used,namely mepiquate chloride,uniconazole,chlormequat chloride,Yuhuangjin,Tontianbao,and Chitosan.They were sprayed during branching stage.Effects of different regulators were investigated on physiological characteristics,agronomic traits,yield,and quality of continuous cropping soybeans.Results showed that 4 growth regulators,including Tontianbao,Yuhuangjin,Uniconazole,and Chitosan,significantly increased yield,with an increase rate of 5.55%-10.3% in 2022,and 1.95%-11.59% in 2023 respectively.The increasing effects ranked in an order from high to low as Chitosan>Uniconazole>Yuhuangjin>Tontianbao.Additionally,the application of Tonianbao,Yuhuangjin,Uniconazole and Chitosan increased content of chlorophyll,soluble sugar,and soluble protein in soybeans,although reduced plant height.They also increased pods number per plant,grains number per plant,and hundred-grain weight.
