| 摘 要： | 本文将气候生产潜力划分为三个层次,即光能生产潜力、光温生产潜力和光温水生产潜力。应用基于供水量与需水量之比建立的光温水生产潜力,计算了北京地区不同播种期的玉米可能产量,得出明显的峰状曲线,其峰值及其相应的播种期即最佳播期均与栽培试验的结论非常一致,这表明气候生产潜力的理论可为农学中的适宜播期问题建立理论基础。

| Abstract: | In this article the potential productivity of climate is divided into three levels:solar radiation, radiation-temperature and radiation-temperature-water. Based on proportion of water supply to water requirement and by using RTW model the author has calculated the possible yield of maize in different seeding time. It is found that the calculated results fit the results of cultivated experiment successfully. It seems to support the idea that the theoretical seeding time in agronomy can be set up by theory of potential productivity of climate. |
