Effect of complex fertilizer of peat and chicken manure on the soil property and fruit quality of Hwangkumhae pear cultivar.

The method of localizing soil amendment was utilized to study the effect of the complex fertilizer of peat and chicken manure on the soil physical and chemical properties and fruit quality for 5-year-old Hwangkumbae pear cultivar trees. The results showed that the soil bulk density in 10 to 40 cm soil layer were lower than that applied homemade manure,especially the soil bulk density in the treatment of complex fertilizer decreased by 33.86%. The contents of organic matter,total N,available P,Mn,Zn and B in soil were increased significantly in treatment C2P2 and C1P1 than those in control. The soluble solid content of fruit was increased by over 1 percent, but no significant difference among the treatments. Canonical correlation analysis of the important soil nutrient elements influencing fruit quality illustrated that the total N and organic matter in soil were the main elements influencing fruit weight and firmness,and were the positive linear correlation. There were positive correlation between soluble solid content and available K, Zn,and the titratable acidity was in positive linear correlation with organic matter and available Fe,but negative correlation with total N content. The comprehensive analysis indicated that the order influencing the fruit quality was as follows: C0P2 C2P2 C0P1C1P1C2P0C1P0CK.
