摘要
利用杂交中稻田间试验等资料， 深入地分析了影响四川盆区杂交中稻生长发育、产量形成的主要气象因子、关键时期和作用规律， 按穗型、粒型分类建立了杂交中稻生育期、有效穗、实粒数、千粒重和产量的气候生态模型， 在四川盆区杂交中稻生产布局和生产决策服务中具有广泛的用途。
By using the field experiment data of hybrid semilate rice,the major climatic factors,key periods and influential patterns of growth and yield component of hybrid semilate rice in Sichuan Basin have been analyzed.Ecoclimatic models of growth duration,effective ears, full grain number,1000 grain weight and yield of hybrid semilate rice have been established according to the classification of ears and grains, which can be applied extensively to production distibution management and decision making of hybrid semilate rice in Sichuan Basin.
