| Alfalfa industrialized production has become the main mode of agriculture system development in arid and semi-arid areas,and is one of the main pillars of agricultural economic development in arid arid areas.Wuwei oasis is located in the east section of the hexi corridor,the upper part of the river valley,which is the typical inland arid area.Drought has long been restricted the development of agricultural economy in the region,and the research on the quality of alfalfa irrigation methods,the influence of the production features such as the production,and choose the optimum planting alfalfa water-saving irrigation mode,has certain guiding significance to the development of water-saving alfalfa industry,to promote the wuwei alfalfa industry sustainable development also has certain practical significance.In this paper,through test in wu mighty south town with no irrigation,conventional flood irrigation,four alternate irrigation and every other furrow irrigation irrigation methods of alfalfa plant height,stem diameter,branch number,stem leaf ratio,net photosynthetic rate,transpiration rate,crude protein content and neutral detergent fiber content and yield was studied,and the nine aspects,such as alternate irrigation and every other furrow irrigation of these two kinds of irrigation methods than the other two kinds of irrigation water,and also compared with other two kinds of planting alfalfa quality irrigation methods better conclusions.Experimental proof of alternate irrigation and every other furrow irrigation water use efficiency were significantly higher than that of traditional irrigation mode,in a 50% reduction in irrigation water,on the basis of the yield and quality of alfalfa has not declined significantly,some indicators have significantly higher.Combined with the ecological environment characteristics of wuwei city in the northwest inland arid region,it is especially important to promote the cultivation of alfalfa.The alfalfa development of the alfalfa industry is in accordance with the national policy orientation and the market sentiment of wuwei,which should be an important measure to promote the development of agriculture and animal husbandry. |
