微咸水膜下滴灌土壤水盐运移研究进展

覆膜灌溉、滴灌和利用微咸水灌溉是极具生命力的3种节水灌溉方式。将三者结合的微咸水膜下滴灌是一项复杂的系统工程，对土壤和作物存在潜在的威胁。因此，近30年来国内外学者对膜下滴灌土壤水盐动态、微咸水灌溉影响效应，以及膜下滴灌土壤水盐运移模型进行了细致研究，并取得大量成果。但是，作物-水盐之间相互作用机理的探寻、田间尺度的盐分迁移转化参数问题，以及如何结合当地土壤水土资源状况，建立安全高效的膜下微咸水滴灌的土壤水盐调控技术体系和灌溉模式，并在区域上推广应用等问题亟待解决。

Advances in Soil Water-Salt Transport of Drip Irrigation Under Mulch with Saline Water

Mulched irrigation, drip irrigation and brackish water irrigation are the most popular water-saving irrigation methods. Mulched drip irrigation of brackish water is a complex system and does threat to soil and plants potentially. Therefore, some detail studies made by the domestic and foreign scholars are about soil water-salt transfer under mulched drip irrigation, the effect of brackish water irrigation and soil water salt transport model under mulched drip irrigation. Meanwhile, the study has got a large number of achievements. However, the quest of the mechanism of interaction between the plants and the soil water salt and the parameters of salt migration and transformation in field scale demands prompt solution. And how to combine soil and water resources in arid regions, establish a secure and efficient adjust and control technology system of water-salt of the soil and irrigation model of drip irrigation under the mulch with brackish water, and regionally promote and apply it, is an urgent need for solving the problem.
