通过磷、钾肥运筹试验，探索了不同运筹方法对水稻产量、产量构成及群体质量的影响，提出了前期施用氮、磷肥，后期施用氮、钾肥为理想的肥料运筹方法。明确了后期增施钾肥的肥效显著，田间表现为生长繁茂、穗大、粒多、粒重，后期清秀活熟，有利于达到高产高效。 Based on the experiments of phosphorus and potash fertilizer operation, the effects of different methods on rice yield, yield components and population quality were explored. The application of nitrogen and phosphate fertilizers and nitrogen and potassium fertilizers at the early stage were proposed. It is clear that the fertilizer efficiency of applying K fertilizer is significant in the late stage. The field performance is flourishing, spike large, grain more, grain weight, delicate and lively in the later period, which is beneficial to achieve high yield and high efficiency.
