棉花生长发育模拟模型COTGROW的建立 I 光合作用和干物质生产与分配

Developed on Cotton Growth and Development Model COTGROW I Photosynthesis and Dry Matter Production and Distribution

本文着重描述了ＣＯＴＧＲＯＷ模型中的光合作用、呼吸作用、各器官的生长、干物质分配、产量与品质形成等生理生态过程，并对１９８６～１９９４年在河南安阳进行田间试验的棉花产量和干物重进行模拟检验，产量拟合指数达０．８８，干物重变化趋势也较一致。

The ecophysiological processes of cotton photosynthesis, respiration, growth of each organ,dry matter distribution, yield and fiber quality forming in theCOTGROW modle was described in this paper. The model was validated using cotton yield and dry matter weight of field experiments in Anyang,Henan, during 1986 and 1994. The result showed that the agreement index(AI) of cotton yield was above 0.88 and the simulated dry matter weight was corresponed with observated value. It showed that the model could be used to sinmulate the cotton production under normal culture condition.
