| Promoting agricultural high efficiency water saving,is the objective requirement of realizing the modernization of agriculture and water conservancy modernization in Yizhou District of Hami City,is an important measure to accelerate the transformation of agricultural development mode,water-saving irrigation mode mainly in drip irrigation,has established a leading position in Yizhou District of Hami City,has made remarkable achievements.First of all,through the investigation of typical plots,get the data flow of drip irrigation in cotton and grape planting,fixed investment of two kinds of crops,crop production cost,irrigation and crop output and income were calculated.grape planting's fixed investment is higher than cotton,grape planting's costs per unit area is higher than cotton,grapes per unit area of irrigation water is higher than cotton,grapes output per unit area is higher than cotton,this is mainly due to the cotton yield per unit area was lower than those of grapes.Secondly,on the basis of constructing the evaluation index system of agricultural high efficiency water saving technology in Yizhou District of Hami City,through to the comprehensive benefit of cotton and grape planting under small flow drip irrigation technology was calculated.It is concluded that the technical benefit,technical effect and economic effect of grape are higher than that of cultivated cotton,and the social benefit and technology of cotton are stronger than that of growing grapes.On the whole,the technology model of drip irrigation under small flow,grape growing efficiency is better.Finally,through the analysis of the evaluation results of agricultural high efficiency water saving effect in Yizhou District of Hami City,and put forward the countermeasures and suggestions to further improve the application effect of agricultural high efficiency and water saving with technology,management,etc. |
