Water-saving Irrigation Experiment of Fast-growing and High-yielding Poplar Plantation

The results of water-saving irrigation trial on sandy land showed that the change of irrigation pattern could save water greatly.Among furrow irrigation,patch irrigation and flooding irrigation,furrow irrigation could save water by 444～750 m3·hm-2·a-1 and 3 270～4 275 m3·hm-2·a-1 respectively compared with patch irrigation and flooding irrigation.Under the three irrigation patterns,no evident difference was found for the increment of poplar.
