通过“3414”肥料试验,模拟预测了几个中稻品种的施肥量与产量之间的关系。结果表明中九优288、杨两优6号、丰两优2号、丰两优香1号等品种与实际相符合。并在此基础上,提出了公安县中稻主产区的稻田丰缺指标与氮、磷、钾施用量的修正值。 Through the “3414” fertilizer experiment, the simulation predicted the relationship between the amount of fertilizer and the yield of several middle-grade rice varieties. The results showed that Zhongyouyou 288, Yangliangyou 6, Fengliangyou 2 and Fengliangyou 1 were consistent with the actual ones. On this basis, the correction index of abundance and deficiency of paddy field and the application of nitrogen, phosphorus and potassium in the main producing areas of middle-season rice in Gong’an County were proposed.
