在国内外近年来玉米生长模拟研究的基础上，结合玉米叶片的光合速率随生育进程变化规律、见展叶差的变化规律及其与干物质生产与分配的关系，研究了玉米冠层光分布、干物质生产与分配的动力模拟模式。经模拟检验，该模式能够较好地反映作物的生长机理，且能够较合理地反映群体的自动调节能力。
Based on the researches on maize growth in recent years both at home and abroad, combining with the variation law of photosynthetic rate of maize leaves along with the growth process, the change law of the difference of addendum and its relationship with the production and distribution of dry matter, the corn canopy light distribution , A dynamic simulation of dry matter production and distribution. The results show that this model can better reflect the growth mechanism of crops and reflect the group’s ability of auto-regulation more reasonably.
