坡地喷灌的规划布置与应用（Planning, layout and application of sprinkling irrigation on sloping fields） Planning, layout and application of sprinkling irrigation on sloping fields Abstract: how to do well the layout of sprinkler irrigation system is the main direction of developing water-saving irrigation in mountain area and half mountain area. It is much more complicated to arrange sprinkler irrigation system on the sloping land than in the flat ground. Besides the consideration of the location of the water source irrigation area, the main contradiction of the terrain should also be taken into account. In this paper, the composition and layout principle of sprinkler irrigation system are briefly described according to the topographic features, and the specific planning, layout and application of sprinkler irrigation in sloping fields are discussed. Key words: sloping land; sloping land irrigation; layout First, the composition of sprinkler irrigation system and the main layout principle (I) composition of sprinkler irrigation system 1. water source project (1): the role of water storage project project mainly lies in the slope runoff and subsurface Ground interception, reduce soil erosion, irrigation, crop yield increase. When the water in the irrigation system in the irrigation area is higher than the layout of the ground, and has the self pressure sprinkler irrigation requirements of the head, often need to use to regulate the construction of reservoirs, water and water pressure; if the water is lower to mechanical pressure, in order to have certain water regulation ability, but also need to build a reservoir, the reservoir volume the smaller the requirements, usually on adjusted. The shape of the reservoir is preferably circular because the circular reservoir holds more than 20% of the square reservoir in the same perimeter. (2) mechanical pressure pumping station: it is better to grade and segment the pressure pump station on slope irrigation system, generally there are two
