Irrigation water is the means by which to enter the active layer of roots, irrigation methods can be divided into surface irrigation, sprinkler irrigation, micro-irrigation and underground irrigation.
surface irrigation
Surface irrigation is an ancient traditional irrigation method, in general, it is pare whether water-saving basis points. Surface irrigation technology are constantly develop and constantly improve, so there are many more water-efficient than traditional surface irrigation technology.
new furrow irrigation tools
Traditional furrow irrigation with artificial opening from the distribution channel water into the furrow, it is neither accurate and inconvenient, and often cause the field of water loss due to water port leakage countries have already adopted the siphon (for open channel water ) or gate hole pipe (aqueduct) drainage, China has done a number of tests, proven to improve field water utilization rate of 5% to 10%.
surge irrigation
Modern foreign developed wave Chung (groove) border irrigation or intermittent ditch (furrow) irrigation, traffic control into the ditch (furrow) is intermittent water a
