摘要
本研究在前人工作基础上,运用光合生产数值模拟方法,针对上海郊区单季稻常规生产和天气特点,根据不同的肥水管理,逐时地计算了单位地面积上水稻的总干重,各器官的物质分配系数,分蘖消长和经济产量,建立了一套含有肥、水影响效应的计算模式,取得了较好效果。
Based on predecessors' studies the authors applied numerical simulation method of photosynthesis production in some experiments with conventional production systems of single cropping late rice in Shanghai suburbs. Total dry weight of rice plants, distribution coefficents of dry matter in diverse organs, index of leaf area, tiller development and economical yield were calculated day by day. A set of models containing effects of fertilizer and water on photosynthesis were established and good results of simulation were achieved.
