PAGE\*MERGEFORMATIV摘要本工程位于中国农业大学石羊河生态与农业节水试验站。果园种植作物为苹果。该设计系统主要采用地下水灌溉，通过收集当地基本资料，拟定规划设计参数，进行水量平衡分析，拟定出比较合理的灌水制度。在此基础上进行了管网规划布置及水力计算，并选择各个管道的经济管径，保证了管材使用的经济性。最后，做了工程的概预算，该工程总投资约30583.46元。经济效益显著，六年的时间即可还本，并且使果园增产15%以上。总体而言，该工程是一套与我国的经济发展水平相适应的高效节水灌溉工程。关键词：滴灌灌溉，苹果园，设计说明AbstractTheprojectislocatedinShiyangheExperimentalStationforWater-savingofAgricultureandEcology,ChinaAgriculturalUniversity.Thecropoftheorchardisapple.Thissystemmainlyusesgroundwaterforirrigation,andbycollectingbasicinformationonthelocal,planningdesignparameters,doingwaterbalanceanalysis,itwillthendevelopamorereasonablesystemforirrigation.Onthisbasis,wewilldoaplanningofthepipenetworklayoutandhydrauliccalculation,andchoosetheeconomicdiameterofeachpipe,asfaraspossibletoensurethattheuseoftheeconomy.Finally,wedoaprojectbudget,whichwithatotalinvestmentof30583.46Yuan.Theeconomicbenefitsoftheprojectissignificant.Ittakeslessthansixyearfortheprojecttopaybackfortheprincipalandwiththeproject,orchardscanyieldmorethan15%.Overall,theprojectisanefficientwater-savingirrigationprojectwhichisadaptedtothelevelofoureconomicdevelopement.Keywords：Dripirrigation，Appleorchard，Designspecification目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc264555393"摘要PAGEREF_Toc264555393\hIHYPERLINK\l"_Toc264555394"AbstractPAGEREF_Toc264555394\hIIHYPERLINK\l"_Toc264555395"目录PAGEREF_Toc264555395\hIIIHYPERLINK\l"_Toc264555396"第一章绪论PAGEREF_Toc264555396\h1HYPERLINK\l"_Toc264555397"第二章工程概况PAGEREF_Toc264555397\h2HYPERLINK\l"_Toc264555398"2.1当地水文经济概况PAGEREF_Toc264555398\h2HYPERLINK\l"_Toc264555399"2.2苹果生长概况PAGEREF_Toc264555399\h3HYPERLINK\l"_Toc264555400"2.3苹果树灌水时期PAGEREF_Toc264555400\h3HYPERLINK\l"_Toc264555401"第三章滴灌系统设计PAGEREF_Toc264555401\h5HYPERLINK\l"_Toc264555402"3.1灌水器选择和规划设计参数PAGEREF_Toc264555402\h5HYPERLINK\l"_Toc264555403"3.2水量平衡计算PAGEREF_Toc264555403\h7HYPERLINK\l"_Toc264555404"3.3管网布置PAGEREF_Toc264
