土壤质地对地下滴灌灌水器水力要素的影响（Effect of Different Textural Soils on Hydraulic Characteristics of Emitters under Subsurface Drip Irrigation）
地下滴灌 灌水器 土壤质地

为研究不同质地土壤中灌水器水力要素的变化规律及其差异，选取灌水器工作压力、土壤容重和土壤初始含水率为因素，分别在粘土、壤土和砂土中采用混合水平均匀设计安排试验。试验结果表明，不同土壤中的灌水器出流规律一致：即当工作压力不变时，灌水器流量在灌水初期略大，而后减小并趋于恒定，这个变化过程仅1～2min；在相同压力下，地下滴灌灌水器流量比地表滴灌小5%～20%，压力越大，二者越接近；灌水器流量随工作压力...
