2、组田问小区试验,对沼液不同灌溉量处理与常规施用化肥的对照处理进行了对比,结果表明,施用沼液可促进柑桔生长,对衡量土壤质量的几种重金属含量等基本无不利影响,且土壤中总氮、有机质等有所增加。用300000kg-hmt沼液浇灌替代化肥,可使柑桔增加产量8.59%,还可增加柑桔果实町溶性固形物含量,沼液处理A的果实中总糖比化肥对照提高0.6个百分点,总酸降低0.262百分点,果实糖酸比明显提高,糖酸比与施用化肥的对照相比差异达显著水平(P3、:柑桔;沼液;土壤质量;品质中图分类号:S181文献标志码:A文章编号:1672—2043(2011)11-2300-06InfluenceofApplyingBiogasSlurryonYieldandQualityofCitrusandSoilEnvironmentWANGWei—pin91,LUXifi-mia02,WEIZhang-huan2,CHENXiao-yan91,XUEZhi-yon91,HUYu—ehu3,HONGChun—lai‘,ZHUFeng-xiang1’(1.InstituteofEnvironmentResources&SoilFe4、rtilizer,ZhejiangAcademyofAgriculturalScience,Hangzhou310021,China;2.AgriculturalTechniqueExtensionCenterofNinghaiCounty,Ninghai315600,China;3.ForestryTechniqueExtensionCenterofNinghaiCounty,Ninghai315600,China)。Abstract:Biogasfermentationofwastewaterreleasedfromlivestockandpoultryfar5、msisoneofthemostimportantwaystocomprehensivelymanagethestockraisingpollution.However,disposalofalargeamountofbiogasslurryhasbecomeachallenge.Inthisstudy,incorporatingbiogasslurryinirrigationoncitruswasinvestigated.Fieldplotexperimentswithmulti—repeatrandomizedblocksdesignwereperformed6、toas—sesstheinfluenceofdifferentamountofbiogasslurryonsoilpropertyandtheyieldandqualityofcitrus.Theresultsshowedthatbiogasslurryirrigationcouldpromotecitrusgrowthandimprovethesoilqualitybyincreasingthetotalnitrogenandorganicmatterbuthadnodetrimentaleffectontheheavvmetalcontentsoftheso7、ilcomparedwiththeblankcontrolsusinggeneralchemicalfertilizer.Productionofcitruswasin—eroasedby8.59%withapplicationof300000kg·hm4biogasslurryinsteadofchemicalfertilizers.Thesolublesolidscontentoffruitwasim—provedaswell.Totalsugaroffruitwasincreasedby0.6%andtotalacidwasdecreasedby0.262%8、.Ther
