Management Technique and Irrigation System of Irrigating Forage by Central Fulcrum Irrigation Machine

Application time of central fulcrum irrigation machine in large-scale planting of forage was relatively short in our country and management technique was general lack.Irrigation system was formulated mostly according to experience so as to result in uneven application effects.Common concepts of soil moisture were introduced.Irrigation management technology，irrigation system making method and selection of sprinkler head for central fulcrum irrigation machine were put forward in order to achieve scientific irrigation and increase forage yield and income.
