摘要： Quinoa (Chenopodium quinoa Willd.) is a crop with high tolerance to salinity and droughtand its response to varying soil moisture and salinity levels was studied in a field lysimeterexperiment. Quinoa (cv. Titicaca) was irrigated with different concentrations of saline water(0, 10, 20, 30 and 40 dSm~(-1)) from flowering stage for 18 days (FI_0, FI_(10), FI_(20), FI_(30) and FI_(40)) andthen irrigation continued with tap water. Measured yield, soil water content (SWC) and soilwater electrical conductivity (EC_w) under the various saline conditions were compared withsimulated yield, SWC and ECw with the water management model SALTMED. The modelcalibration was carried out for the unstressed crop (FI_0), while the other treatments (FI_(10), FI_(20),FI_(30) and FI_(40)) were used for model validation. The results showed that the model has theability to simulate seed yield and total dry matter (seed yield + straw yield) even for stressedplants under field condition. In addition, the model simulated reasonably well the SWC andthe EC_w of the root zone.
