摘  要:
This paper analyzed on the development situation and tendency of the sprinkler and micro irrigation technique worldwide. Authors summarized the successful experiences on the development of sprinkler and micro irrigation in USA, Israel and India. The main factors impacted the development of sprinkler and micro irrigation are as follows: per capita of water resources, per capita of GNP, ratio of agricultural labor to the total population, attention paid by government, subsides supported by government, research and training. In conclusion, authors pointed out that water saving is the major advantage of the sprinkler and micro irrigation. In addition, it can save labor force, increase the water productivity and crop yields. Lack of labor force and the high cost of labor force are the main driving force for the development of sprinkler and micro irrigation.
