【摘要】 研究对在江西省３个不同生态地区进行的４个品种（或杂优组合）的播种期试验的水稻出叶动态进行模拟，结果表明模拟值与实际观测值吻合较好。该叶龄模型对水稻生长条件的变化具有较高的灵敏度，能用于预测不同类型品种在不同生态条件下的出叶动态。更多还原

【Abstract】 In this paper,the leaf-age model is applied to simulate leaf appearance dynamics in 4varieties(or combination)with different sowing times in three locations(Xiushui,Chongren,Yanshan)in Jiangxi Province.The simulated values of leaf appearance.data agreed well withthe observed data from the field experiments,It indicates that the leaf-age model can adapt todifterent rice growing conditions and be applied to predict the leaf appearance dynamics of ricein different varieties under different growing conditions更多还原
