摘要
回顾和总结了植物补偿与超补偿定义的提出与解释 ,并且根据前人对作物水分亏缺补偿与超补偿效应的研究 ,从理想生态位与现实生态位的角度探讨了其生态学机制 ,从作物对水分胁迫的适应、光合作用、氮代谢、内源激素和植物同化产物运集中心的改变等方面总结探讨其生理学机制 ,用生长冗余理论揭示了补偿与超补偿的本质。阐述了水分亏缺补偿与超补偿效应同农业的关系 。
The definition and explanation to plant compensation and over_compensation are summarized and reviewed. According to the study of predecessors research on water deficit compensation and over_compensation effect, this paper studies the ecological mechanism from the difference between ideal ecological niche and real ecological niche, meanwhile it explores its physiological mechanism from several aspects such as the adaptation to water stress, photosynthesis, nitrogen metabolism, internal hormone and variation of the center of assimilation product etc, the essence of compensation and over_compensation is explained using the growth tediousness theory. Furthermore, the relationship between water deficit compensation effect and the agriculture is elaborated, the development direction and prospect on water saving and water concentrating agriculture are forecasted.
