Study on the characteristics of crop water requirement and consumption in arid zone

  • Online:2017-08-20 Published:2017-08-20

摘要: 基于新疆呼图壁县2003—2012年作物种植面积和降水量等数据,以粮食作物(玉米和小麦)和经济作物(棉花和甜菜)为例,对不同作物年需水总量和年耗水总量以及作物需水量和耗水量随时间变化趋势等进行定量分析。结果表明:4种作物中棉花年需水总量最大,其次为小麦和玉米,甜菜年需水总量最小。从2003年到2012年,作物年需水总量整体呈现增加趋势。多年平均作物需水量为1.87×108m3,并于2007年降至最低,于2012年达到最大,为2.75×108m3。同作物需水量一样,4种作物中棉花年耗水总量最大,其次为小麦和玉米,甜菜年耗水总量最小。作物年耗水总量整体呈现增加趋势,多年平均作物耗水量为2.07×108m3。其中在2003年作物耗水总量最低,于2010年达到最大。研究区作物耗水量基本与作物需水量保持一致,能够满足作物生长需要,但同纬度不同地区作物耗水量不尽相同。

Abstract: Based on the data of crop planting area and precipitation between 2003 and 2012,the different crop(corn,wheat,cotton and sugar beet)water demand and water consumption were analyzed.The results showed that:The total amount of water of cotton in the 4 crops was the largest,followed by wheat and corn,and the total amount of water in sugar beet was the minimum.The annual water demand of economic crops was significantly higher than that of grain crops.Total annual water demand of crops showed an increasing trend between 2003 and 2012.For many years the average crop water requirement was 1.87×108 m3,and it was the lowest in 2007,it reached the maximum in 2012,which was 2.75×108 m3.In consistent with crop water demand,the total annual water consumption cotton in the 4 crops was the largest,followed by wheat and corn,and the total water consumption of sugar beet was the smallest.The total annual water consumption of crops showed an increasing trend between 2003 and 2012,and the average crop water consumption was 2.07×108 m3.Among them,crop water consumption was the lowest in 2003,and reached the maximum in 2010.The crop water consumption in the study area was consistent with the crop water requirement,which can meet the needs of crop growth,but crop water consumption was different in different regions of the same latitude.
