1. Model development for simulating rice-weather relationsA dynamic simulation model for rice-weather relations (SIMRIW) was developed by integrating knowledge and experimental data on processes of rice development, dry matter production and yield formation. The SIMRIW satisfactory explained the locational and yearly variations of rice growth and yield in the U.S.A.and Japan. It also explained growth and yield formation dynamics observed at International Rice Research Institute (IRRI) in Philippines based on daily weather.The SIMRIW has been distributed over major rice research institutes in the world through IRRI for the validation and improvement at each site.2. Synthesis of the model for evaluating nitrogen (N) effect on rice growthIn order to incorporate. N factor into SIMRIW,a analysis was made on data including those from comparative rice cultivation experiments among Kyoto, Nagano and Yanco in Australia. Based on these data, model for estimating soil N mineralization rate and one for evaluating N effect on leaf area development, on dry matter production and on organ formation processes has been synthesized and validated.

1.水稻与天气关系的动态模拟模型（SIMRIW）是综合水稻生长发育、干物质生产和产量形成过程的相关知识和试验数据，建立的水稻与天气关系动态模拟模型。SIMRIW较好地解释了美国和日本水稻生长和产量的区域和年度变化。并根据菲律宾国际水稻研究所（IRRI）观测到的每日天气情况，对水稻生长和产量形成动态进行了解释，SIMRIW已通过IRRI分发到世界各主要水稻研究所，供各研究所验证和改进.水稻氮素效应评价模型的综合。将N因子导入SIMRIW，对京都、长野、扬科等地水稻比较试验资料进行了分析。在此基础上，建立了土壤氮素矿化速率估算模型和氮素对叶面积发育、干物质生产和器官形成过程影响的估算模型。
