摘要
作物生产力是在“环境—作物”系统内形成的。本文根据作物环境资源(光、热、水分和养分)建立了农业生态系统初级生产力分析模型: Y=F(Q)·f(T)·f(W)·f(M) 并分析了各环境因子影响作物生产潜力发挥的程度。
Crop productivity depends on 'environment-crop' system.A model for the primary productivity of agroecosystem was established in this study based on the environmental resources( e.g.light, heat, water and nutrients) of crop. The model is Y = F(Q)·f (T)·f (W)·f (M). Each environmental factor which affected the extent of potential productivity of crop was analyzed.
