劣质水农业高效安全利用技术的研究现状及其展望

Status and prospects of high-efficient and safe utilization of poor quality water for agriculture

总结了我国劣质水回用于农业灌溉方面的研究现状,对本领域最新的研究动态及其今后的发展前景进行了展望。我国劣质水用于农业灌溉的研究工作正在逐步开展,微咸水与再生水中N、P、COD、可溶性盐分和重金属在土壤、作物及水体中的迁移转化规律等方面的研究已取得一定成果。把劣质水、土壤、农作物、地下水作为整体进行综合性机理研究,将节水灌溉技术与劣质水的安全高效利用结合起来的纵深性研究等将成为今后研究工作的重点。

Basis on a review of the application of poor quality water in agriculture irrigation, the up-to-date research results and prospects of further investigation were presented. Some achievements on the research of the regularities about movement and transformations of N, P, COD, dissolvable salts, and heavy metals, which are contained in brackish water and regenerated water, in soil, crops and waters have been obtained. The comprehensive mechanism study with the poor quality water, soil, crop and groundwater taken as a whole and the combination of water-saving irrigation technology with high-efficient and safe utilization of poor quality water would be emphasized in further research.
