| 摘 要： | 为探究微纳米气泡增氧灌溉技术对水稻节水增产的综合影响,以陆两优996和天优华占为双季早、晚稻试验材料,研究了不同施氮水平下微纳米气泡增氧灌溉对双季稻需水特性、产量及产量构成因素的影响。结果表明,微纳米气泡增氧灌溉处理的灌水量、排水量和耗水量均低于常规水灌溉处理,早、晚稻水分利用效率(耗水量)分别提高7.78%和8.37%,降雨利用效率分别提高6.03%和24.58%,产量分别提高4.05%和3.35%。同时,微纳米气泡增氧灌溉具有良好的节肥效果。

Effects of Micro-Nano Bubble Aerated Irrigation on Water Requirement Characters and Yield of Double Season Rice |

| Abstract: | In order to study the comprehensive effect of micro-nano bubble aerated irrigation on water-saving and yield-increase of rice, under the different nitrogen levels, a field experiment was conducted to study the effects of micro-nano bubble aerated irrigation on water requirement characteristics, yield and yield composition of the early rice Luliangyou 996 and the late rice Tianyouhuazhan.The results indicated that compared with conventional irrigation, micro-nano bubble aerated irrigation reduced the irrigation amount, water discharge and water consumption and increased the water use efficiency by 7.78％ for early rice and 8.37％ for late rice.The utilization rate of rainfall was enhanced by 6.03％ and 24.58％, and the yield was increased by 4.05％ and 3.35％ for early rice and late rice, respectively.Moreover, the micro-nano bubble aerated irrigation had a well fertilizer-saving. |
