摘　　要：本文通过开展不同滴灌带类型、不同滴头流量在苜蓿地下滴灌的应用试验,探究不同滴灌带类型、不同滴头流量对苜蓿生长、产量的影响。结果表明,滴头流量为中流量处理(2.0 L/H)的增产作用和节水效果明显高于低流量处理(1.38 L/H)和高流量处理(3.0 L/H);滴灌带类型不同时,内镶贴片(蛇形孔)滴灌带比内镶贴片(圆孔型)滴灌带和贴条式滴灌带表现效果要好。建议选择内镶贴片(蛇形孔)滴灌带更为适宜,滴头流量选择中流量处理(2.0 L/H),增产作用和节水效果明显。This article explores the effects of different drip irrigation belt types and drip head flow rates on the growth and yield of alfalfa through the application experiments of underground drip irrigation with different drip irrigation belt types and drip head flow rates. The results showed that the yield increasing and water-saving effects of the medium flow rate treatment (2.0 L/H) were significantly higher than those of the low flow rate treatment (1.38 L/H) and high flow rate treatment (3.0 L/H);When the type of drip irrigation tape is different, the performance of the internal patch (serpentine hole) drip irrigation tape is better than that of the internal patch (circular hole) drip irrigation tape and the strip type drip irrigation tape. It is recommended to choose an embedded patch (serpentine hole) drip irrigation tape for better suitability, and to choose a medium flow rate treatment (2.0 L/H) for drip head flow rate, which has a significant increase in yield and water-saving effect.
