| Abstract: | Laiyuan Ginkgo Nursery in Yanfang Township of Zhanyi District of Yunnan Province adopts drip irrigation mode.The designed irrigation area is 180hm2.Branch pipe and capillary pipe layout is the core content of drip irrigation design.Basic data and irrigation system in the project area are regarded as foundation.Laying parameters of branch pipes and capillary pipes are determined through hydraulic calculation.The project area is divided into ten groups for cycled irrigation.The irrigation cycle is 5d,and irrigation duration is 6h,net duty of water is 18 mm,gross duty of water is 20mm,and water dropper flow capacity is 2L/h,and water head under work pressure is 15m.Finally,branch pipe laying length is 60m,the span is 60m,50 holes are set,pipes at the level of 0.8MPaDN63PE100 are selected,capillary pipe laying length is 100m,the span is 1.2m,100 holes are set,pipes at the level of 0.6MPaDN25PE100 are selected,and 16 (0.15MPa) pressure compensation water droppers are used. |
