挖掘作物抗旱节水潜力——作物对多变低水环境的适应与调节

本文针对半干旱地区多变低水的实际田间环境,讨论了作物对不同干旱类型的反应,适度干旱后复水的生理补偿效应,不同类型作物在干湿交替条件下的差异,以及增强作物对多变水环境适应的技术.同时,就多变低水环境的概念、作物对多变低水环境的适应机理以及作物抗旱生理研究与旱农生产实际相衔接等问题提出了若干看法.

Crop drought resistance is very complex. Till now, its mechanism has not been understood in detail. How to combine basic research with agricultural practice is still a problem facing us. Therefore, the study on multiple drought resistance of crops seems to be important. Taking the crop as a whole, to clarify the relationship of the crop and its environment and to improve cultivation techniques is practicable to realize high yield. Considering this, low and variable water conditions in semiarid environment w...
