绿色环保高效的设施蔬菜土壤滴灌施肥体系

Environmental Protected and High-Efficiency Fertigation System for Protected Vegetables

土壤滴灌施肥技术是基于栽培作物的需水需肥规律,依据实时定量供液、维持根层水分养分稳定技术原理的一种新型水肥一体化施肥技术,解决了传统土壤栽培水肥供应使根系长期处于饥饱交替逆境胁迫下及土壤易产生次生盐渍化等问题,同时实现了轻简省力、自动化和水肥高效利用的目标。详细介绍了土壤滴灌施肥的技术原理、主要装置及系统构成、技术基础及国内外应用实例,为该技术推广应用提供参考。

The fertigation technology was a new integrated water-fertilizer management technoliogy based on the water and nutrient requirements of crops, and it maintained the water and nutrient stabilization of root layer according to the real-time quantitative irrigation. The fertigation technology solved the problems involving irregular water-fertilizer supply and soil secondary salinization in traditional soil cultivation. In addition, it realized the goals of simplification, labor-saving, automation and high efficient use of water-fertilizer. To provide references for the extension and application of the fertigation technology, this article reviewed its technology principle, the main equipment and system-construction, technological basis and application examples both in China arid abroad in detail.
