加气灌溉技术对土壤及作物生长影响的研究OA
Research Progress on Effects of Aerated Irrigation Technology on Soil Environment and Crop Growth
传统灌溉会导致土壤水气不平衡,造成作物根区低氧胁迫,而运用加气灌溉技术可以有效改善土壤的通气性能,农作物的产量与质量都有所提高.为此,主要对根区低氧胁迫的机理进行分析与阐述,基于 CiteSpace 综合整理了加气灌溉技术相关参数及应用现状,系统论述了加气灌溉技术在改善土壤环境和提高作物产量方面的研究进展与发展难点;同时,深入分析了该技术在改善土壤环境及作物生长等方面取得的成效和存在的问题,针对目前存在的技术缺陷进行探讨;最后,分析了加气灌溉技术的未来发展趋势与研究方向,为加气灌溉技术的推广应用提供理论参考与技术借鉴.
In traditional irrigation,it will lead to the imbalance of soil water and air,resulting in hypoxic stress in the root zone of crops.The study found that aerated irrigation technology can improve soil aeration and improve crop yield and quality.In this paper,the mechanism of hypoxic stress in the root zone was analyzed,and the relevant parameters and application status of aerated irrigation technology were comprehensively sorted out based on CiteSpace.The potential and application prospects of aerated irrigation technology in improving soil environment and crop yield were systematically dis-cussed.The achievements and existing problems of this technology in improving soil environment and crop growth are dis-cussed,and the problems existing in the current aerated irrigation technology are discussed for reference.
