中国农业大学硕士学位论文中文摘要摘要本研究在对山东省出口注册果园和出口企业系统调查的基础上,针对在山东省梨的出1:3中存在的植物捡疫、农药残留超标、果实品质变劣和梨果生产及加工过程中规范性操作等安全性问题,做进一步的研究分析,找出了山东省出口梨检验检疫限制因子的最佳控制、避免或降低措施。,对山东省出I:1注册梨园上主要病虫害进行了定性的风险评估,提出了通过源产地控制和产后控制降低植物检疫风险的措施,从而降低山东省出口梨植物检疫限制因子的影响。,在梨的生长季节,调查山东省出13注册梨园的用药种类,对山东省出口注册梨园施用农药情况进行了客观评价。,每年在梨果采收、分级包装、贮藏和市场销售期间,对山东省梨出口注册果园和加工厂调查显示:山东省出口梨品质变劣的主要原因是出现霉心病、“水纹病”、果肉褐变和干腔、黑皮病。本研究针对以上问题提出了相应控制措施。(GoodAgriculturalPractice)P(HazardAnalysisandCriticalControPoint)的主要内容和关键控制点,提出了山东省梨出口注册果园和注煅加工厂的规范性操作。关键词:出口梨,检验检疫风险,规范性操作,控制措施,panies,furtherresearchandanalysiswereconductedinthisstudyparticularlyonthesafetyissuesincludingplantquarantine,over-amountedchemicalresidue,,theoptimamavoidingandreducingmeastlreSwereadvancedoninspectionandquarantine--paidpestsbyvariousimportcountries,riskanalysesweredoneonthemajordiseasesandinsecffspidermitepestsofregisteredpearorchardsinShandong,uponwhich,themeasuresforreducingplantquarantineriskswereputforwardthroughoriginalproducingorchardcontrolandpost-harvestcontrol,inorderthattheimpactsofplantquaruntine-,chemicalsusedbyShandongregisteredpearorchardswereinvestigated,,theinvestigations,cardedoutduringpearharvest,gradingandpackaging,storingandmarketing,showedthatdegradationofShandongexportpearsweremainlyfrommoldyCOreandcorerot,“waterstriaedisease”,fruitfleshbrowningandcavity-forming,(GoodAgriculturalPractic
