文章编号：1673-887X(2023)01-0007-03不同肥料对芒果品质的影响张燕，刘清国，段军娜，黄海（贵州省亚热带作物研究所，贵州兴义562400）摘要以红玉芒为试验材料，设置常规施肥（CK）、羊粪有机肥（T1）、油枯有机肥（T2）、巴迪生物肥（T3）、沸力佳生物肥（T4）等5个处理进行田间试验，通过测定芒果果实15个外观品质及内在品质指标，并采用主成分和聚类分析对不同处理下的果实品质进行综合评价，为提升芒果品质的施肥管理提供参考依据。结果表明：生物肥对芒果外观品质的改善作用优于有机肥处理；有机肥和生物肥均可提高芒果的硬度、可溶性固形物含量及风味品质。主成分分析得出不同处理下芒果品质排序为T3>T4>T1>CK>T2，聚类分析将不同处理聚为3类，CK、T1和T2聚为一类、品质为三等、T4聚为一类、品质为二等、T3聚为一类、品质为一等，生物菌肥对芒果果实品质的改善作用优于有机肥，其中巴迪生物肥（T3）的效果最为显著。关键词芒果；品质分析；主成分分析；聚类分析中图分类号S14-33；S667.7文献标志码Adoi:10.3969/j.issn.1673-887X.2023.01.002EffectsofDifferentFertilizersonMangoQualityZhangYan,LiuQingguo,DuanJunna,HuangHai(GuizhouSubtropicalCropResearchInstitute,Xingyi562400,Guizhou,China)AbstractAbstract：WithHongyumangoastheexperimentalmaterial,fivetreatmentsincludingconventionalfertilization(CK),sheepmanureorganicfertilizer(T1),oil-driedorganicfertilizer(T2),Badibio-fertilizer(T3)andFeilijiabio-fertilizer(T4)weresetupforfieldex‐periment.Fifteenappearanceandinternalqualityindexesofmangofruitweredetermined,andthefruitqualityunderdifferenttreat‐mentswascomprehensivelyevaluatedbyprincipalcomponentanalysisandclusteranalysis.Theresultsshowedthatbio-fertilizerwasbetterthanorganicfertilizerinimprovingtheappearancequalityofmango.Organicfertilizerandbiologicalfertilizercanim‐provethehardness,solublesolidcontentandflavorqualityofmango.Principalcomponentanalysisshowedthatmangoqualityun‐derdifferenttreatmentswasrankedasT3>T4>T1>CK>T2.Clusteranalysisshowedthatdifferenttreatmentsweregroupedintothreetypes,CK,T1andT2weregroupedintoonetype,thequalitywasthirdclass,T4wasgroupedintoonetype,thequalitywassecondclass,T3wasgroupedintoonetype,thequalitywa...
