Abstract: Used field crops to the measured data between 2012 and 2015,compared with traditional cropping pattern,with analysis of the Inner Mongolia food crops and forage crops film with drip irrigation to increase production efficiency and large sprinkler irrigation.Research shows that after implementing membrane under drip irrigation,soybean,corn,potato yield increased by 10.91%～69.29%respectively,water productivity were increased by 27.68%～157.83%.After the implementation of large-scale irrigation,corn,alfalfa,feed corn silage maize yield increased by 8.24%～10.3%respectively,and the water productivity increased by 8.13%～41.15%.Overall,after implementation of water saving irrigation project,main food with crop and forage crop in Inner Mongolia has great increase production efficiency.
