The water demand,total water demand and staggered water demand,which produced the seed grain of one kilogram with No.1 of Avena nuda in the different output level during the course of planting in Qaidam basin,was quantificationally studied by the statistic method.The relationship between the water demand and different output level were discussed, and the scientifically irrigative measure were taken.The result showed that ameliorating the cultivated measure,increasing fertilization,improving irrigative technology,etc should be the first primacy of basis on basically satisfying the water demand,not consist with improving the irrigative water demand of unit area in order to reach the high output level of 7000-9000 kilograms.Meanwhile,the period of two leaves and one center was the best irrigation phase in the young plant;during the middle phase,the period of polarization of gynoecium and androecium and connectives of anthers and overlay apparatus was better;while in the final phase,the water of building storeroom was irrigated enough at the base of irrigating the water of flowering.
