摘　　要：冷型小麦是基于Ⅰ级和Ⅱ级气候系统背景下对Ⅲ级气候系统的一种适应性响应。本文从小麦Ⅲ级气候系统、小麦温度型和冷型小麦概念出发,概括介绍了冷型小麦理论基础,从小麦潜在库容、冷温状态、叶片逆向衰老、含有动力因素的小麦高产稳产模式等,剖析了冷型小麦抗逆增产的生态生理机制,意在逐步实现小麦对环境的深度适应,并从根本上提高小麦高产、稳产、优质、高效的水平。Cold-type wheat is an adaptive response to Climatic system Ⅲ against the backdrop of Climatic systems Ⅰ and Ⅱ. The Paper briefly introduces the theoretical basis of cold-type wheat starting from the concepts of three Climatic systems and temperature and cold types of wheat, and analyzes ecological and physiological mechanisms in resistance and yield increasing of cold-type wheat in terms of potential sink capacity, cold-temperature condition, reverse leaf aging, and driving factor-involving models for wheat to increase and stabilize its yield, with the intention that wheat progressively and deeply adapts itself to its environments so as to progressively and deeply increase its high and stable yield and high quality and efficiency to a higher level.
