几年来,我们以河海大学为技术依托单位,以和平水稻试验站为技术辐射基地,全力推广水稻控制灌溉节水技术,总结出了符合庆安县实际的“返青地湿润,露泥不汪水;糵初建水层,汪水不露泥;糵后重控制,田干地裂缝;黄熟防早衰,再灌一茬水”的节灌方法。与传统灌溉方法对比,田间耗水量减少38.6％,蒸腾量降低37.8％,棵间蒸发量降低21.2％,亩净用水量降到360立方米以下,亩节油、节电费20-26元,节约灌水成本45％左右。通过测产,
Over the past few years, we rely on Hohai University for technical support units, the Peace Rice Experimental Station as a technology radiation base to promote rice control irrigation water-saving technology, summed up in line with the actual Qing’an County Water; 糵 early built aquifer, Wang water is not exposed mud; 糵 after heavy control, field dry land fissures; Huangshu anti premature senility, reperfusion a stubble water "irrigation method. Compared with traditional irrigation methods, field water consumption decreased by 38.6%, transpiration decreased by 37.8%, and inter-tree evaporation decreased by 21.2%. The net water consumption per mu dropped below 360 cubic meters, saving fuel per mu and saving electricity costs of 20-26 yuan, saving About 45% of irrigation costs. By measuring production,
