摘要
概述了干旱对我国水稻生产的影响。从产量构成因素的角度分析了干旱导致水稻减产的原因,从光合特性、活性氧积累、内源激素和多胺含量、干物质积累等方面分析了水稻生长对干旱响应的生理机制。同时总结了轻度干旱胁迫后的水稻补偿效应。对未来减轻干旱对水稻生产的影响,合理充分利用水稻补偿效应做出了展望。
This paper outlines the impact of drought on rice production in China.From the perspective of yield components,the causes of rice yield reduction were analyzed.The physiological mechanisms of rice growth response to drought were analyzed from the aspects of photosynthetic characteristics,active oxygen accumulation,endogenous hormones and polyamine content,and dry matter accumulation.At the same time,the compensation effect of rice after mild drought stress was summarized.To reduce the impact of drought on rice production in the future,and make rational use of rice compensation effect.
