Landsberg 等(1982)和 Weir 等(1984)曾对模拟冬小麦生长摸式发表过看法。在完全模式中,明显区分谷类作物的生长过程与发育过程。生长是作物截取光能进行干物质积累的过程,即光合作用和干物质分配的过程。发育包括两个部分,即物侯状态的变化和产生光合面的营养发育过程,本文描述的模式只涉及冠层发育(Weir 等,1984),但也试图考虑作 Landsberg et al. (1982) and Weir et al. (1984) expressed their opinion on the simulation of winter wheat growth. In the complete model, there is a clear distinction between the growth and development of cereal crops. Growth is the process by which crops intercept light energy for dry matter accumulation, ie photosynthesis and dry matter distribution. Development consists of two components, the change in state of matter and the development of photosynthetic vegetative development. The model described herein deals only with canopy development (Weir et al., 1984) but also attempts to consider
