摘要
以4个早晚兼用型超级稻品种(桂农占、玉香油占、合美占和胜泰1号)为材料,研究了大田条件下灌溉模式对不同基因型水稻品种的产量、品质及水分利用效率的影响。结果表明,与常规灌溉相比,半量灌溉条件下各水稻品种的每穗总粒数显著增加,稻米的整精米率和蛋白质含量显著提高,而且灌溉用水量显著减少,水分利用率的提高也达到显著水平。
Effects of irrigation mode on yields,grain qualities and water use efficiency were studied using four extensive-adaptation super rices(Guinongzhan,Yuxiangyouzhan,Hemeizhan and Shengtai 1) in a field experiment.Compared by conventional irrigation(CI),total grain number per panicle was increased,head milled rice rate protein content of grain improved under half amount of conventional irrigation(HACI),significantly.What is more,the amount of consumed water was remarkably decreased,water use efficiency markedly increased under HACI.
