本文试用Mitscherlich方程研究建立水稻干物质总量与叶面积指数、群体密度的动态关系,这对于了解水稻群体结构的动态变化有着一定的意义. This paper attempts to establish a dynamic relationship between the total dry matter content of rice and leaf area index, population density using the Mitscherlich equation, which is of certain significance for understanding the dynamic changes of rice population structure.
