Effects of Spraying KH2PO4 on the Yield and Its Components of Strong Gluten Wheat
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 phos-phate on the yield and its components of strong gluten wheat in eastern Hebei province under the field experi-mental 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 di-hydrogen phosphate on the 10th day after flowering,the yield of strong gluten wheat reached its maximum,in-creasing 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 glu-ten 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%com-pared to the control treatment at the same period.In this field experiment,spraying 3 g/L potassium dihydro-gen phosphate on the 10th day after flowering was the optimal treatment combination for improving the yield of strong gluten wheat in eastem Hebei province.
