摘　　要：文章从比较我国南方和北方（以淮河、秦岭为界）气候特性的差异出发，从生理生态、成本投入、产量以及光能利用等方面比较了生产营养体和生产籽粒的差别，针对作物营养生长与生殖生长对光照要求的差异，并结合已有实例提出了在我国南方应改变传统的种植模式，大力发展营养体农业的新观点。The climatic resources were compared between the north and south of China in the study. The vegetative agriculture and traditional agriculture were contrasted in physiological ecology, cost inputs, utilization efficiency of solar energy and vegetative and grain yields. Based on the differences of the requirements of radiation between vegetative agriculture and traditional agriculture, large development of vegetative agriculture, instead of focusing on traditional agriculture, was proposed through utilization of winter fallow croplands in the south of China.
