| 摘 要： | 在总结前人研究的基础上，我们尝试了用生态学观点来解释作物产量的形成，引入“环境压力”的概念和反映作物产量和产量构成因素与相应的量化农艺措施之间变化关系的一个共同指标一在环境压力作用下产量构成因素变化的斜率ＳＰ，简称压斜。由是总结出了通过对压斜的比较分析，寻找作物产量突破的“压斜分析法”。该分析法具有数量化和程序化的特点，具有较好的适用性。文中用具体试验资料对该方法的操作给予了演示，对其特点和应用进行了讨论

| Abstract: | A new interpretation of crop yield that based on ecological principles has been employed in this study. When the concept of enverimental pressure has been usnered in ,the slope that repersents the relationship of an agronomy measure and the yield or a yield component a certain yield level got its new meaning:a commom index of the increas trend of the yield or a yield content under the enverimental presure, noted as Sp. For a certain agronomy combinatiorial measures,there was a Sp set. Through the analysis and comperation of the Sp set ,an approach of higher yield could be found.In this paper the characteristics and usage of the Sp-method has been discussed and an applied example has been given. |
