减氮配施有机肥对枇杷果实品质的影响
Effect of nitrogen reduction combined with organic fertilizer on the quality of loquat fruit
摘要
Abstract
[Objective]This research aims to study the effects of nitrogen reduction combined with or-ganic fertilizer on the quality of loquat fruit,to provide theoretical basis for scientific fertilization in loquat cultivation.[Method]Three-year-old'Dawuxing'loquat trees were used as experimental materials,and field trial was adopted.Five treatments were set up:no fertilizer(CK),conventional fertilizer(CF),30%nitrogen reduction combined with commercial organic fertilizer(LOF),60%nitrogen reduction combined with commercial organic fertilizer(MOF),and 90%nitrogen reduction combined with commercial organic fertilizer(HOF).The effects of these treatments on the appearance,flavor,and nutritional quality of loquat fruit were investigated.On this basis,effects of different treatments on improving loquat fruit quality were comprehensively evaluated with principal component analysis(PCA)and entropy weight method,respec-tively.[Result]Compared with CK,CF significantly increased the longitudinal diameter,transverse diame-ter,single fruit weight,and edible rate of loquat fruit.Compared with CF,treatments of nitrogen reduction combined with organic fertilizer(LOF,MOF,HOF)further significantly increased the above indices.Com-pared with CK,CF treatment significantly increased soluble sugar content and sugar-acid ratio,and signifi-cantly decreased titratable acid content.Compared with CF,LOF,MOF and HOF treatments all signifi-cantly increased soluble solids content and sugar-acid ratio,and significantly decreased titratable acid con-tent,with only MOF significantly increasing soluble sugar content.Compared with CK,CF treatment sig-nificantly increased the total flavonoids content,while no significant difference was observed in Vc,soluble protein and total carotenoids content.Compared with CF,MOF and HOF treatments significantly increased soluble protein,total carotenoids and total flavonoids content,while no significant difference of the above indices was observed in LOF treatment.[Conclusion]Nitrogen reduction combined with organic fertilizer significantly improved the appearance,flavor,and nutritional quality of loquat fruit,with 60%nitrogen re-duction(MOF)being the optimal treatment.关键词
