摘  要：
以离式螺旋微气泡泵为微纳米气泡发生装置,对比研究了微纳米气泡增氧灌溉技术在双季稻灌区节水减排中的应用效果。结果表明,微纳米气泡增氧灌溉技术可以减少灌水量、排水量和耗水量,提高降雨利用率和灌溉水利用率,从而有效减少氮磷地表径流排放量。与常规水灌溉处理相比,早、晚稻采用微纳米气泡增氧灌溉技术分别节水(灌水量)7.44%和4.46%,降雨利用率分别提高5.92%和4.28%,灌溉水利用效率分别提高13.36%和10.54%,总氮排放量分别减少8.36%和8.12%,总磷减少27.5%和27.27%。

摘  要：
The application effect of micro-nano bubble aerated irrigation technique was researched on water conservation and waste water discharge of irrigation area of double-cropping rice by using the micro-nano bubble aerated generating device with off type spiral micro bubble pump.The results indicated that compared with the traditional treatment of water irrigating,the use of micro-nano bubble aerated irrigation technique can effectively reduce the discharges of nitrogen and phosphorus in the surface runoff by decreasing the irrigation and drainage volumes and water consumption to improve the effective utilization of rainfall and efficiency of irrigation water use.For early and late rice,the use of micro-nano bubble aerated irrigation technique conserved water(irrigation water)by 7.44% and 4.46% respectively,increased the effective rainfall utilization by 5.92% and 4.28% respectively,improved the irrigation water use efficiency by 13.36% and 10.54%respectively,as well as reduced the discharge of total nitrogen by 8.36% and8.12%respectively,the removal rate of total phosphorus were reduced by 27.50% and 27.27% respectively.
