本研究的目的是评估灌溉间隔对生菜生产，品种。“Regina”，在NFT水培系统中。2005年5月至6月在圣玛利亚的联邦大学作物科学系进行了一项实验。处理是在15分钟冲洗后的三个冲洗间隔（15分钟、30分钟和45分钟）。实验设计为完全随机区组设计，重复三次。在移栽时和移栽后6、9、16、20和23天测量叶面积、地上部和总干物质。连续灌溉之间的处理45分钟的间隔允许42.1%的节省电能而不降低莴苣产量。
The objective of this study was to evaluate irrigation intervals on the production of lettuce, cv. 'Regina', in an NFT hydroponic system. An experiment was carried out at the Crop Science Department, Federal University of Santa Maria, from May to June 2005. Treatments were three irrigation intervals (15 min, 30 min, and 45 min) after a 15 minutes irrigation. The experimental design was a complete randomized block design with three replications. Leaf area, and above ground and total dry matter were measured at transplanting, and at 6, 9, 16, 20 and 23 days after transplanting. The treatment 45 minutes interval between successive irrigations allowed a 42,1% saving electric energy without decreasing lettuce yeld.
