Abstract: 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.
