通过对水稻品种９５２０穗肥促、保不同比例试验，探索了穗肥不同运筹方法对水稻群体质量的影响，明确了高产栽培条件下水稻穗肥最佳运筹方法。超高产栽培条件下，穗肥运筹应采用平衡法，即分别在叶龄余数３．５、２．５、１．５、０．５时四次等量施用；穗肥的促、保不同比例对产量影响无明显规律，具体应视苗情而定，高产栽培可选择６∶４或５∶５。 The effects of different methods of panicle spike fertilization on rice population quality were explored through experiments of promoting and conserving spike fat of rice variety 9520, and the best method of panicle spike fertilization under high-yielding cultivation was clarified. Under the condition of super-high-yielding cultivation, the balance method should be adopted for panicle and panicle operation, that is, the same amount should be applied in four times at leaves 3.5, 2.5, 1.5 and 0.5 respectively. No significant impact on yield, depending on the seedling situation, 6:4 or 5:5 for high yielding cultivation.
