Abstract: 【Objective】 To explore the growth characteristics and water consumption of D.glomerata under drought stress. 【Method】 Seven D.glomerata materials from different sources were used as the research objects to observe their growth characteristics.The weighing method was used to study the change in water consumption. 【Result】 (1) As the drought stress increases, the growth rate of each material slowed down, and the plant height, tiller number, and above-ground and above-ground biomass gradually decreased; (2) The water consumption law of the seven D.glomerata materials was basically the same and increased with the drought stress; Water consumption showed a gradual decrease trend, but there were differences in water consumption characteristics among materials; (3) Comprehensive growth and development and water consumption characteristics showed that D.glomeratas in Nilek County, Xinjiang had the best performance, followed by Dactylus Oregon in the United States and D.glomerata in Urumqi, Xinjiang. 【Conclusion】 The growth characteristics and water consumption of Dactylis from different provenances show a decreasing trend with the increase of drought stress.In general, Xinjiang wild Dactylis has a certain drought resistance and is better than the two cultivated varieties, so it has important cultivation value.
