Abstract: | Objective]To study the effect of spraying plant growth regulators on yield and yield components in the filling stage.Method]By spraying calcium chloride solution,potassium dihydrogen phosphate solution, borax, salicylic acid, sodium sulfite solution, the effect of plant growth regulators on yield and yield factors were analyzed.Result]The effect of spraying potassium dihydrogen phosphate was best, compared with control, the number of grains per spike,1 000-grain weight significantly increased,and yield increased by up to 3.61% in Cangzhou area. Conclusion]Calcium chloride solution is suitable in wheat production application in Cangzhou area. |
