摘要
为了给内蒙古阿鲁科尔沁旗饲草燕麦(Avena spp.)灌溉提供科学依据,本研究利用1984-2013年30年气象数据,采用联合国粮农组织推荐的彭曼-蒙特斯公式法,研究了内蒙古阿鲁科尔沁旗饲草燕麦需水规律和灌溉定额.结果表明,内蒙古阿鲁科尔沁旗饲草燕麦第1、2茬和全生产期需水量分别为370、297和667mm,需水强度分别为4.1、2.9和3.5mm/d,灌溉需水量分别为295、149和443mm,灌溉定额分别为347、175和522mm.
Abstract
To provide a scientific basis for oats(Avena spp.)irrigation in Ar Horqin Banner of Inner Mongolia Autonomous Region(AHBIMAR),the 30 year′s meteorological data from 1984 to 2013 of AHBIMAR,and the method of FAO Penman-Monteith equation were employed,the water requirement regularity and irrigation quota of oats in AHBIMAR were studied.The results showed that the water requirement of oats for the first harvest,second harvest,and whole production period in AHBIMAR were 370,297 and 667 mm,respectively.The water requirement rate were 4.1,2.9 and 3.5 mm/d,respectively.The irrigation requirement were 295,149 and 443 mm,respectively.The irrigation quota were 347,175 and 522 mm,respectively.
