滴灌技术是70年代才发展起来的一种新的灌溉方法。它是利用低压管道系统,使灌溉水点滴地、缓慢地、不断地浸润农作物根系最发达的区域,以保证供应作物对水分的需求。在目前各种灌溉方法中它具有最省工、省水、节能、增产和适应复杂地形需要等优点,同时不产生地表迳流和土壤板结,不会形成重力水的渗漏。在水源不足的坡地、山区和保水保肥力差的砂质土 Drip irrigation technology was developed in the 70s a new irrigation method. It is the use of low-pressure pipeline system, the drip irrigation water drip slowly and constantly soaked in the most developed areas of crop roots in order to ensure the supply of crops for water needs. In the current various irrigation methods it has the most labor-saving, water saving, energy saving, yield and adapt to the needs of complex topography and other advantages, while not producing surface tributaries and soil compaction, will not form the leakage of gravity water. Slope in poor water, mountains and water and poor fertility sandy soil
