新疆额敏灌区砂质壤土滴灌线源入渗规律
Infiltration characteristics of line-source drip irrigation in sandy loam soil,Emin irrigation district,Xinjiang
摘要
Abstract
To investigate soil water movement under line-source drip irrigation,a study was conducted using an indoor soil tank setup with three emitters on sandy loam soil from the Emin Irrigation District in Xinjiang.The experiment included three emitter spacings(10,20,and 30 cm)and three emitter flow rates(1.0,1.5,and 2.0 L/h),resulting in a total of nine treatments.The wetting front dynamics were monitored over a 6 h irrigation period.The results showed that:1)Both the horizontal and vertical wetting front movement distances were best described by a power function of infiltration time(R²>0.98).2)At the same emitter spacing,higher flow rates resulted in shorter wetting front convergence times(the shortest being 1 min)and shallower vertical infiltration depths at convergence(the shallowest being 4.2 cm).However,they led to greater final vertical infiltration depths at the end of the irrigation period(up to 39 cm).3)At the same emitter flow rate,larger spacings led to longer wetting front convergence times(up to 55 min)and deeper vertical infiltration at the moment of convergence(up to 11.5 cm).However,they resulted in smaller final vertical infiltration depths at the end of irrigation(as shallow as 23.1 cm).This study elucidates the synergistic mechanism of emitter flow rate and spacing on the wetting pattern,providing a scientific basis for optimizing drip irrigation system parameters and design in the Emin Irrigation District.关键词
