Abstract
To enhance the quality and yield of strong-gluten wheat in Luxi Region,this study investigated optimal micronutrient protocols for local varieties and elucidated the mechanisms by which different micro-fertilizers influence yield formation and quality regulation.Using strong-gluten wheat variety"Jima 44"as experimental material,four foliar spray treatments were applied:0.2%zinc sulfate,0.5%manganese sulfate,0.3%potassium dihydrogen phosphate,and 0.1%potassium dihydrogen phosphate,with water as the control.Spraying was conducted during jointing,booting,and grain-filling stages.Yield components factors,grain crude protein content,and wet gluten content were measured at maturity to compare the regulatory effects of different micronutrient fertilizers.Results demonstrated that the 0.3%potassium dihydrogen phosphate treatment yielded the most significant effects,followed by the 0.2%zinc sulfate treatment.Priority should be given to applying 0.3%potassium dihydrogen phosphate in wheat production practices.关键词
