A field plot experiment was carried out to study the effects of different organic manure application rate on mango fruit quality and soil fertility.The result showed that compared with chemical fertilizer (CK),the applications of organic manure increased the fruit total soluble solid,Vc,ratio of tss and acid,by 10.1%~21.6%,3.1%~38.4%,17.9%~44.9%,total titration acid decreased by 6.6%~16.0%.Meanwhile,different organic manure application rates increased soil organic matter,total nitrogen,available phosphorus,available potassium,exchangeable calcium,exchangeable magnesium,electrical conductivity and pH,then soil fertility was improved significantly.Applying 7.5 kg organic manure with 400 g urea and 1.25 kg high potassium compound fertilizer to each plant was the best,which improved the fruit quality and soil fertility effectively.
