Research and application on the movable subsurface drip irrigation system

Basing on summarizing the advantages and the disadvantages of different types of drip irrigation systems, the movable subsurface drip irrigation system which gathering the virtues of subsurface and movable drip irrigation was excogitated. The reutilization rate of every fixing was improved effectively for the pattern of quick connection and entirely movement of system equipments. Through the field appliance on tobacco, it is indicated that all of system components are installed and removed conveniently, the effect of emitters application is good, so the system has characteristic of move neatly, better practicability, storage expediently and maintain easily on the whole. The average investment is about 2500 Yuan/ha, the total annual cost is 807.5 Yuan/ha. It can be widely used in resisting drought for tobacco, vegetables, melon and other similar non-close planting cultivated crops in the area of droughty massif and collect-rainwater cellar area, and can irrigate the wide-row planting crops in plain region too.
