中文摘要：
采用单因子随机区组试验方法,在内蒙古阿拉善左旗巴彦浩特镇希泥套海嘎查村进行了干旱地区不同灌水方式对油葵生长及水分利用效率的影响试验,定期测定油葵生长指标及土壤含水率。结果表明,膜下滴灌出苗比露地滴灌早3d,全生育期内膜下滴灌的株高、叶面积指数和干物质积累量均高于覆膜微喷、管灌＋覆膜沟灌和露地滴灌,且产量分别提高了42.53%、7.03%和27.01%。膜下滴灌群体WUE比露地滴灌、覆膜微喷和管灌＋覆膜沟灌分别增加47.48%、11.18%和31.26%。
英文摘要：
In Xinitaohaigacha village,Bayanhaote town,AlashanZuo county of Inner Mongolia,an experiment was conducted to study the influence of different irrigation methods on the growth and water use efficiency of oil sunflower.The results showed that the seedling emergence time of under mulched drip irrigation is 3dearly than that of outdoor drip irrigation;during the whole growth period,the plant high,leaf area index and dry matter accumulation of under mulched drip irrigation were higher than those of under mulched sprinkling irrigation,pipe irrigation with under mulched furrow irrigation,and outdoor drip irrigation,and the yield was increased by 42.53%,7.03% and 27.01%,respectively.The WUE of drip irrigation under mulched was increased by 47.48%,11.18% and 31.26%,respectively,than outdoor drip irrigation,sprinkling irrigation under mulched and pipe irrigation with under mulched furrow irrigation.
