摘要
综述了高产棉花在生理基础方面取得的成就及新进展，并对有关问题进行了讨论。综述和讨论的主要问题：①棉花的影响及水分利用效益；②棉花各生长期的需肥特性；③光合系数对棉花群体透光率的影响，种植密度对光能利用率的影响及光合速率和蒸腾速率变化规律的研究。
Recent development study in the high yield cotton physiological mechanism was reviewed and the concerned problems were discussed. The subject is reviewed and discussed as follows:①Water potential of cotton leaves and endosmosis adjustment, leaves transpiration, effect of the water defict on nitrogen and carbon metabolism, water use efficiency.②Regulation of requiring fertilizer in different growth periods of cotton. ③Effect of the peviousness to light among the inside of cotton colony on the photosynthetic index, plant densities affecting the light energy use efficiency and photosynthetic rate, transpiration rate were studied.
