根区等高覆盖灌溉——一种新的农田节水集成配套综合技术初探与展望

Root-zone Same Height Mulching Irrigation——A New Type Comprehensive Matching Integration Technique for Farmland Water-saving of

结合我国干旱半干旱地区农业生产中普遍存在的农田高效节水灌溉、水肥一体化施肥、秸秆覆盖还田、提高土壤肥力等主要问题,采用农机与农艺相结合的方法,以创新农田高效节水灌溉的技术与方法为中心,同时注重把水肥一体化施肥、秸秆覆盖还田等主要问题与之深度融合,形成一种新的农田节水集成配套综合技术——根区等高覆盖灌溉。在对这一综合技术的概念、实现方式、功能定位等进行初步探讨的同时,对开展根区等高覆盖灌溉综合技术研究前景进行了展望。

Aiming at the existing problems in the promotion of high efficient water-saving irrigation,fertigation,fields covering with straws,improving soil fertility in the agricultural production in arid and semi-arid regions,the root-zone same height irrigation,as a new type comprehensive matching technique for farmland water-saving integration is proposed.The technique fuses irrigation,fertigation and fields covering with straws to achieve the high efficient water-saving innovation by combining agricultural machinery and agronomic technology.This paper preliminarily discusses the related concept,implementation mode and functional localization of the comprehensive technique and analyzes the prospect of the root-zone same height irrigation technique.
