植物生长调节剂对连作大豆产量及其相关性状的影响
Effects of plant growth regulators on yield and related traits of continuous cropping soybean
摘要
Abstract
To improve quality and efficiency of continuous soybean cultivation through chemical control,ef-fects 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 random-ized 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 Ton-tianbao,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.关键词
