摘要
从作物生理生化、农田生态环境等方面详细论述了冬小麦节水灌溉生理生态基础的研究进展。其研究主要集中在作物本身生物学特性、土壤水分与根系关系、农田生态环境3个方面,每个方面研究已较深入,但对这3个方面的综合性研究及边缘学科间的协作研究还比较薄弱。今后应从土壤-作物-大气连续体(SPAC)出发,着重研究在冬小麦高产优质栽培条件下,节水灌溉对冬小麦与水分关系的影响及其生理生态机制。
This paper discusses the research progress of the physiol ogical and e cological basis for watersaving irrigation of winter wheat from the viewpoint of crop physiology and cropland environment. Most researches are concentrated wi thin three aspects: the biological characteristics of plant, the relationship be tween soil water and plant root, and the environment of atmosphere. Each of thes e three aspects has been studied in deep, but the synthetic study of them and th e study of the marginal subjects are deficient. In the future, emphasis should b e placed on the relationship between the high yield, quality and efficiency of w inter wheat and soil water and its physiological or ecological mechanism on the basis of soilplantatmosphere continuum.
