| 摘 要： | 磷钾肥配合施用,可增强小麦群个体素质,提高成穗率,增加千粒重,达到高产稳产的目的。增施磷钾肥可提高强筋小麦蛋白质和湿面筋含量,改善小麦籽粒品质。中等肥力田块强筋小麦生产,氮:磷:钾配比应掌握在1:0．4:0．4,磷钾肥以底施50％、拔节期追施50％,施用量P2O596kg／hm2,k2O96kg／hm2为最佳。

| Abstract: | Phosphorus potassium cooperates and uses, can strengthen group and individual quality of wheat, raise the forming ear rate, increase 1000-grain weight, achieve the purpose of stable high yield. Increasing the phosphorus potassium can improve the strong gluten wheat protein and content of wet gluten, improve wheat grain quality. Producing strong gluten wheat in medium fertility field, nitrogen: Phosphorus: potassium should grasp matching at 1:0.4:0.4, basal dressing 50% and elongation stage dressing 50% phosphorus potassium, consumption by P2O5 96 kg/hm2; k2O 96kg kg/hm2 is best. |
