Research status and development suggestions of drip irrigation under plastic film mulching in saline-alkaline areas
摘要
Abstract
Drip irrigation under plastic film mulching,as an important technique to effectively alleviate the problems of low agricultural water use efficiency and soil salinization,has achieved remarkable results in the development and utilization of saline-alkali land in China in recent years.To understand the current research progress of this technology,the impacts of drip irrigation under plastic film on soil water-salt movement and crop growth in saline-alkali land were comprehensively analyzed,and the differences in the effects of different irrigation systems on water conservation and salt control were explored.It was found that this technology could significantly reduce the salt content in the topsoil,increase the water content of the surface soil,optimize the physiological metabolic processes of crops,and improve crop yield and quality.Adopting reasonable irrigation frequency,irrigation quota,and drip irrigation pipe layout had obvious positive effects on water conservation and salt suppression.However,research results were weak in aspects such as the impacts of long-term use of the technology on soil and the ecological environment,quantitative studies on irrigation frequency and irrigation quota,and universal studies on drip irrigation pipe layout,which restricted the large-scale popularization and application of the technology.Suggestions for subsequent research and development were put forward,aiming to provide references for the further research and popularization of subsurface drip irrigation under plastic film and offer scientific basis and practical guidance for the improvement and sustainable utilization of saline-alkali land.关键词
