摘　　要：在调研新疆地区滴灌工程基础上,分析了地区现行滴灌工程管网布置及长度确定方式,提出运用毛管最大长度计算公式和经济指标作为重要衡量参数,确定田间毛管布置的最经济长度。结果表明,在毛管间距相等情况下,毛管铺设经济长度会随滴头间距增加、流量减小而增加。同时,增加灌水小区面积,田间毛管经济长度亦会增加。On the basis of extensive investigation of drip irrigation projects in Xinjiang,this paper analyses the layout of drip irrigation network and the way to determine the length of drip irrigation projects in Xinjiang,and puts forward the formula for calculating the maximum length of capillaries and economic indicators as important measurement parameters to determine the most economical length of field capillary arrangement. The results show that under the condition of equal capillary spacing,the economic length of capillary laying increases with the increase of dripper spacing and the decrease of flow rate. At the same time,the economic length of field capillary will increase with the increase of irrigation plot area.
