【摘要】 借鉴 C.T.de Wit和 F.W.T.Penning de Vries的建模思想和 MACROS中 L1 D、TIL的基本框架 ,通过田间试验和文献资料的收集 ,组建了适合本地土壤条件、气候状况和品种特性的水稻群体质量指标动态模拟模型。利用该模型实时模拟 ,并以产量的高低作为标准进行优化 ,获得了秧龄、移栽期和基本苗的最优组合以及相对应的水稻群体质量若干优化指标更多还原

【Abstract】 Based on C.T.de Wit & F.W.T.Penning de Vries’s modelling methodology and fundamental frame of L1D and TIL modules of MACROS,a dynamic simulation model of quality indexes in rice population suitable to local soil,climate and other varietal characters was conducted according through field trials and documental data.By running the model,the optimum combinations of seedling age,transplating date and the number of transplated seedlings with corresponding optimum indexes of rice population quality were obtained.更多还原
