摘　　要：农业研究通常投入大 ,见效慢。用作物生长模型模拟技术 ,是解决这一问题的理想方法。为了用CERES玉米模型模拟优质蛋白玉米品种叶片增长 ,在泰国清迈大学进行品种×播种期的双因素试验。试验有 3参试种 ,3个播种期 ,共 9个处理。试验结果表明 ,用CERES玉米模型模拟的最大叶面积指数、总叶片数、叶片干物质重 ,模拟值均高于实际值 ,这主要是因为准确的土壤和气候数据不易得到所致 ,因此只有当土壤和气候数据可靠时 ,CERES玉米模型才能用于指导研究和其他工作。Agricultural research program is usually expensive and time consuming. One alternative to solve this problem is to use modeling and simulation technique. In order to simulate growth of leaves for Quality Protein Maize (QPM) cultivars by using Crop-Environment Resource Synthesis (CERES) maize model, a variety × planting date experiment was conducted in Chiang Mai University, Thailand. There were 3 planting dates and 3 varieties, which came to 9 treatments. The results showed that the CERES-maize model overestimated maximum leaf area index (LAI), final leaf number, leaf dry weight dynamic. This is because the soil and climatic data usually could not be recorded precisely, the models could be applied to guide the research and extension works only when accurate soil and climatic data are available.
