发展了一个具有生物学基础的、兼具实用性和理论性的水稻生长模拟模型。它是在水肥适宜的条件下，以光、温因子模拟作物生长过程。其空间尺度是叶面水平的，时间尺度是逐时的，并且具有模拟冠层瞬时光合作用的能力。该模型由发育阶段、冠层光分布、冠层光合速率和叶面积指数增长等子模型组成。使用地理分期播种资料进行了检验，该模型可以解释在不同气候区域水稻干物质积累随生育期和播种期变化的９２５％～９５８％。使用常规气象资料，用数值方法研究了南京、长沙、广州和贵阳等地杂交水稻的气候生态适应性。模拟结果表明，贵阳气温低、生育期长，其中稻生育期内温度适中、光照较强，干物质生产力高。广州气温高，中稻、早稻生育期短，产量较低，因受低温的影响小，是晚稻的高产区。南京和长沙以在生长中后期能避开盛夏高温并能正常抽穗扬花的适播晚稻干物质产量较高 A biologically based, practical and theoretical model of rice growth has been developed. It is in the water and fertilizer suitable conditions, with light and temperature factors to simulate the crop growth process. The spatial scale is leaf-level, the time scale is hour-by-hour, and has the ability to model transient canopy photosynthesis. The model consists of sub-models such as development stage, canopy light distribution, canopy photosynthesis rate and leaf area index increase. The data were analyzed using geographic sowing date. The model can explain 925% ~ 958% of dry matter accumulation in rice in different climatic regions with the growth and sowing times. Using conventional meteorological data, the climatic and ecological adaptability of hybrid rice in Nanjing, Changsha, Guangzhou and Guiyang was studied numerically. The simulation results show that Guiyang has low temperature and long growth period, of which rice has moderate temperature, high light intensity and high dry matter productivity. Guangzhou high temperature, medium rice, early rice growth period is short, low yield, due to the impact of low temperature, is a high yielding area of ​​late rice. Nanjing and Changsha in late growth can avoid the high temperature in midsummer and normal heading and flowering suitable late rice dry matter yield is higher
