我国旱区作物根域微集水种植技术研究进展及展望

概述了我国旱作区作物根域微集水种植技术的增产机理与效果,在总结现有研究基础上,指出了目前根域微集水种植技术研究中存在的若干问题,并提出针对该技术的完善与深化应加强其影响作物生产力机制及水肥耦合机理方面的研究,科学评价在不同雨量区根域微集水种植的应用效果和水保效应,同时应进一步规范根域微集水种植技术的相关技术标准和操作规程。作者认为该技术在深化试验研究与广泛示范的基础上,在旱农区有十分广阔的应用前景,是提高旱区降水资源化效率及作物增产的重要技术途径。

Progress and prospect of research on root-zone water micro-collecting farming for crop in arid region of China

A comprehensive overview is made on the yield-increasing mechanism and effect of crop root-zone water micro-collecting farming in arid regions of China. Based on existing research, there still existed a number of issues in the current root-zone water micro- collecting farming technology research so the studies on improving and strengthening the technology''s impact on crop productivity and water and fertilizer coupling mechanism were put forward. Moreover, we should make a scientific evaluation on the effect of application and water and soil conservation of root-zone water micro-collecting farming under different rainfall. And it is important to further standardize the related technical standards and procedures of root-zone water micro-collecting farming. On the basis of further experimental study and extensive demon. stration, we concluded that the technology would be very widely used in anid areas, which would be an important way of improving resource efficiency for precipitation and increasing crop yield in arid areas.
