对水分亏缺下小麦根系生物学特性响应的研究进展进行了综述 ,从根系形态、生理生化、基因型进化角度阐述了小麦在水分亏缺下作物的自我反馈调节能力 ,并由此提出了作物在旱地或灌溉条件下 ,开掘土壤水分利用效率 ,进行生物节水的农艺措施 The research progress on the response of wheat roots to water deficit was reviewed. The ability of crops to self-regulate and regulate their responses to water deficit was discussed from the aspects of root morphology, physiology, biochemistry and genotype evolution. Under dryland or irrigation conditions, digging soil water use efficiency, the biological water saving agronomic measures
