【正文】 nd water, carried out a detailed investigation, collected the relevant data for the project area, the suitable Grassland Irrigation promotion of watersaving irrigation measures, through the parison of engineering layout, program, project scale, construction contents were determined, pleted the preparation of the implementation programme for the project. After the implementation of the project, can solve the Su Ji Tan Xiang herbs Liang Cun irrigation problem 3000 acres of artificial grassland, grassland desertification control. To further improve the grassland ecological environment, improving grassland productivity, promote the animal husbandry Menyuan County pastoral industry to high yield, high quality development. Keywords: crop water requirements, irrigation systems, the design flow, piping engineering 目錄 1 綜合說明
