In order to understand the situation of pear production and provide a basis for improving quality and efficiencyas well as green development in Chongqing，32 pear orchards in 7 representative dominant pear production regions wereinvestigated and analyzed，including fertilizerinput，soil nutrient status，nutrients content of leaves and fruits，yield andquality of pears.The results showed that，1)The average total inputs ofN，P 2O5，K 2O in the survey region were687， 426 and 434 kg/hm²，respectively.The average inputs of organic fertilizerN，P，K only accounted for20.52%、9.39%和 15.21% of the total nutrientinputs，respectively.The average ratio of nutrient input to N∶P 2O5∶K2O was 1∶0.62∶0.63.2)The average soil pH value of pear orchards was 5.33.The contents of soil organic matter，alkali -hydrolyzablenitrogen，available phosphorus and available potassium were all in the middle or above middlelevel.3)The contents ofphosphorus，potassium and calcium in pear leaves at maturity stage were generally in the suitablestate，and the contents ofnitrogen and magnesium in nearly half of the leaves were in the suitablerange.4)The yield of pear ranged from 9 to 45 t/hm² and the average yield was 24 t/hm²，the content of solublesugar，titrableacid，vitamin C and soluble solids ranged from0.95% to6.98%，0.07% to0.15%，1.18% tO₂.77%，and 2.60% to3.95%，respectively.5)There was a significant positivecorrelation between soil pH and leaf magnesiumcontent，and an extremely significant negative correlation between soil pHand leaf nitrogen content.There was a significant positive correlation between soil available phosphorus and leaf nitrogencontent.The soluble solid content in pear fruit was negatively correlated with the magnesium content inleaf.The contentof potassium in leaves was significantly and positively correlated with solublesolids，soluble sugar and acid -solidratio，and extremely significantly and positively correlated with sugar-acidratio.The application rate of fertilizerN，P，K in theseregions was large and the proportion imbalance wasserious.The nutrient input was mainlyfertilizer，and the proportion oforganic fertilizer waslow.It has showed great potential for improving yield according to the big yield gap among differentorchards.With the current average yield of 24 t/hm² in Chongqing’s pear orchard as thetarget，the recommended amount offertilizer application can refer to the followingstandards:N，P 2O5 and K2O are338，165 and 345 kg/hm²respectively.Basedon leaf nutrition diagnosis and soil nutrientstatus，pear fruit quality diagnosis can be carried out in advance to improve qualityand efficiency.Chongqing ’s pear orchard should take the measures of "reducingacidity，reducing nitrogen andphosphorus，controllingpotassium，increasing magnesium and retaining organicfertilizer".It is suggested to adjust nutrient supply according to the law of fertilizer demand of pear trees and local conditions in combination with soil nutrient status and leafnutrition diagnosismethod，so as to guide pear orchard to fertilizereasonably，and improve the yield and quality ofpear.
