科学施用穗肥是水稻中、后期管理的重要组成部分,对产量的形成和提高有极重要的作用。本试验依据叶龄进程,研究不同叶龄期施用穗肥对产量形成效应及其植株形态影响,以便确定该品种施穗肥的最佳时期,为科学施用穗肥提供依据。该试验于1990、1991年重复进行两次。
Scientific application of panicle fertilizer is an important part of middle and late rice management and plays an important role in the formation and improvement of yield. Based on the leaf age process, this study studied the effects of panicle fertilizer application on the yield formation and plant morphology at different leaf ages in order to determine the optimum period for applying this method to spike fertilization and provide scientific basis for the application of panicle fertilizer. The trial was repeated twice in 1990 and 1991.
