【摘要】 以江南双季稻生长评估模型为工具,模拟了常德地区1961-2000年早稻的生长状况。利用 40年早稻各生育期干物重和成熟期穗重的模拟值,对该地早稻历年各生育期长势和产量进行差、较差、正常、较好和好五级评价。通过与1982-2000年常德地区早稻实测产量相比较,检验了模拟和评价结果的准确性。更多还原

【Abstract】 Based on simulated model of JiangNan Double Crop Rice,growth and development status of early rice effected only by climate condition in ChangDe Area from1961to2000were simulated respectively.With simulated results of dryweight in the end of each stage of early rice and panicle weight in its maturity stage,growth vigor of early rice in ChangDe Area from1961to2000were assessed by five levels with very poor,poor,normal,good and very Good.In the end,simulated results and their assessment results were checked by analyzing and assessing practical yields in ChangDe Area from1982to2000.更多还原
