Abstract:
Taking the 8-year-old pear tree as materials,the effect of different levels of urea use on pears yield,and fruit quality and nitrogen content in soil plough layer were studied.The results showed that high nitrogen area (86.9 kg/667m2) increased yield significantly higher than middle (43.4 kg/667m2) and low nitrogen area(21.7 kg/667m2)；fruit hardness,soluble solid content,protein content,vitamin C content of middle nitrogen were higher than in the area of high nitrogen area;soil plough layer hydrolytic nitrogen content was low after the fruit picking residual stock.Comprehensive consideration,pears yield and fruit quality were the best in middle nitrogen area.
