Abstract
Water consumption characteristics of four irrigation methods,furrow irrigation,under-mulching-drip irrigation,subsurface irrigation and node subsurface irrigation,were studied by tomato greenhouse experiment.The relationships between irrigation quantity and yield,water use efficiency of tomato were discussed.The mechanism of water consumption differences was analyzed.Furrow irrigation,under-mulching-drip irrigation,subsurface irrigation and node subsurface irrigation of irrigation quantity is 1473.99,1181.66,1168.07,889.91 m3/hm2,water use efficiency is 42.00,53.96,54.55,70.37 kg/m3,respectively.The results showed that nod subsurface irrigation is suggested optimal irrigation method because of the advantages of fewer irrigation quantity,high water use efficiency and little effect on soil temperature.In addition,water surface evaporation can be used to guide irrigation practice in greenhouse.
