摘　　要：为探究磷酸二氢钾(KH_(2)PO_(4))喷施时期和质量浓度对冀东地区强筋小麦产量及其构成因素的影响,以强筋小麦品种中麦886为供试材料,大田条件下,设置4个KH_(2)PO_(4)溶液喷施质量浓度,分别为0(CK),2,3,4 g/L;3个喷施时期,分别为孕穗期、花后第10天、花后第20天,测定分析了完熟期强筋小麦中麦886的产量及其构成因素。结果表明:(1)在花后第10天喷施质量浓度3 g/L的KH_(2)PO_(4)处理下,强筋小麦产量达到最高,比同时期CK处理提高8.76%;(2)在花后第20天喷施质量浓度3 g/L的KH_(2)PO_(4)处理下,强筋小麦千粒质量达到最大,比同时期CK处理增大3.95%;(3)在孕穗期喷施质量浓度3 g/L的KH_(2)PO_(4)处理下,强筋小麦穗粒数达到最大,比同时期对照处理增大6.13%。本次田间试验下,在花后第10天喷施质量浓度为3 g/L的KH_(2)PO_(4)为提高冀东地区强筋小麦产量的最佳处理组合。The yield and composition factors of strong gluten wheat Zhongmai 886 during the full maturity stage were analyzed to investigate the effects of the spraying period and concentration of potassium dihydrogen phosphate on the yield and its components of strong gluten wheat in eastern Hebei province under the field experimental conditions with the material of strong gluten wheat variety Zhongmai 886,treatments of spraying 0 g/L,2 g/L,3 g/L,and 4 g/L potassium dihydrogen phosphate solution concentrations on the booting stage of 10th day and 20th day after flowering.The results showed that under the treatment of spraying 3 g/L potassium dihydrogen phosphate on the 10th day after flowering,the yield of strong gluten wheat reached its maximum,increasing by 8.76%compared to the control treatment at the same period;under the treatment of spraying 3 g/L potassium dihydrogen phosphate on the 20th day after flowering,the thousand grain weight of strong gluten wheat reached its maximum,increasing by 3.95%compared to the control treatment at the same period;under the treatment of spraying 3 g/L concentration of potassium dihydrogen phosphate during the booting stage,the number of grains per spike of strong gluten wheat reached its maximum,increasing by 6.13%compared to the control treatment at the same period.In this field experiment,spraying 3 g/L potassium dihydrogen phosphate on the 10th day after flowering was the optimal treatment combination for improving the yield of strong gluten wheat in eastem Hebei province.
