【摘要】 以赣南9个县市的96个纽荷尔脐橙园为试材,研究树龄、土壤类型、施肥种类和年平均气温对脐橙果实品质的影响。结果表明,随树龄增加,脐橙果实可溶性固形物含量提高;红壤和紫色土果园的果实品质较好,黄壤稍差;施用花生饼肥或生物有机肥为主的果园果实品质更好,可溶性固形物含量和固酸比显著高于施用化肥为主的果园;年平均气温19.2～19.7℃生态区的果实可溶性固形物含量和固酸比显著高于17.7～17.8℃生态区和18.5～18.8℃生态区。更多还原

【Abstract】 Effects of tree age,soil type,fertilization and average annual temperature on fruit quality of Newhall navel orange(Citrus sinensis Osbeck) on trifoliate orange(Poncirus trifoliata(L.)) rootstocks were investigated in 96 orchards in 9 counties of southern Jiangxi province.Results showed that fruit total soluble solids(TSS) were increased as the tree age increased.The quality of fruits sampled from red soil and purple soil orchards was better than those sampled from yellow soil orchards.TSS content of fruits sampled from orchards applied with peanut cakes or bio-organic fertilizers was significantly higher than that of fruits fertilized with inorganic fertilizers and bio-organic fertilizers,and the bio-organic fertilizers were the best.Fruits from areas with average annual temperature of 19.2～19.7 ℃ had better quality than those from areas with annual average temperatures of 17.7～17.8 ℃ and 18.5～18.8 ℃.更多还原
