摘要Lucerne (Medicago sativa L.), as a grass legume is mowed many times in the Hexi Corridor, PR of China, which holds a vital position in the crop-pasture and animal husbandry. Cultivating high-quality lucerne under such extreme water shortage conditions is a necessary approach to develop regulated deficit irrigation (RDI). However, applications of Regulated Deficit Drip Irrigation (RDDI) needs to be explored further in order to increase both the yield and quality of lucerne. Therefore, the main objective of this study was to investigate the effect of different regulated deficit irrigation on soil moisture (SM) dynamics, yield and quality of lucerne. A field experiment was designed with four deficit irrigation treatments in the year of 2013 and 2017. The lucerne was harvested three times per year. Our results showed that with deficit drip irrigation increasing, the yield was decreased for lucerne crop, crude protein (CP), and relative feed value (RFV), while, the content of CP and RFV was increased. SM was directly proportional to the amount of irrigation volume except high water deficit (HWD). Deep SM showed that annual lucerne SM was greater in HWD than in low water deficit (LWD). The biennial lucerne SM was greater in HWD than in each treatment in most cases. Considering the influence factors of yield, qualities and water use efficiency (WUEs (Including WUE, WUE CP and WUERFV)), it is more appropriate that annual lucerne should not be treated with deficit irrigation. In the following year, the LWD reduced the forage yield, but more or less increased the yield of CP (CPyield) and RFV (RFVyield) to compensate the loss of forage yield.
