3、灌溉作对照,研究不同灌溉方式及不同灌溉定额对金桔土壤理化性状、叶片生长发育及果实产量和品质的影响。【结果】各灌溉处理的土壤气相、液相均显著高于对照(P4、对促进金桔生长、提高果实产量和品质具有非常显著的效果。关键词:山地金桔;灌溉效应;灌溉方式;灌溉定额中图分类号:S567.236文献标志码:A文章编号:2095—1191(2015)06—0978-07Effectsofirrigation0nmountajnkⅧmquatLIANGMei—ying,SUShi—hua,UXin-ji锄,TANGJiaJl_jun,ZHAOHai一】【iong(GuilinCenterStationofI而gationTest,Guilin,GuaIl函541105,China)Ab!’b麓ct:【0bjective】麟bctsofirrigationonmo5、untainkumquatwerestudiedtopmVidetheoreticalsupportforinVes-tigatingemcientandcost—savingi耐gationtechnologyinmountainarea8.【Method】T’vokinds0firrigationmet}10dswereinitializedas:A(dripirrigation)andB(micr0sprinkleri耐gation),eachmethodwitllfourtreatments(1—4)accordingtoirrigationquotaof2250.0,3000.O,36、750.0,4500.0m弧aandnoilTigation眈atment船CK,e舶ctsofdi船rentirriga-tionmetllodsaIldirrigationquotaonsoilphysical锄dchemicalpmperties,le“grow山,缸lityieldandqualityofkumquatwere咖died.【Result】nesoilgasphaseandliquidph鹅eofdmrentirrigationtreatlIlentsweresignific锄dyhigllerth蛐CK(P≮0.05,thesamebelow),butsolidphas7、ewas10werth粕CK;tllesoilavailablenutrientcontentof2250.0—3750.OmⅦatreatmentswerehigherth肌CK,A2treatlIIentw髂thehighest,B3treatIIlentw黯alsoatahighlevel.Underd诳毛renti而gationquota,山erelative刚hrateofnewshootsaIldleaf,chlomphyUcontentwemhigherthanCK.ThetreesleavesofA2orB3treatIIlentgrewbestintller}e酉on.Com8、paredwithCK,tIIeyieldofd瀣÷rentirrigationtreatIIIentsincre勰edsignmcandy,andthequal畸w鹊impmVedobViously.’11leyieldofA2andB3treatmentw鹪tllehighestintllere。西on,粕dtllequalityw鹊alsobetterthanother讹atment8.【C
