摘要： It is highly significant to reduce the amount of chemical fertilizer application in mango orchards and substituting it with organic manure. The field location method was applied to examine the effects of substituting chemical fertilizer with organic manure on soil physical and chemical properties, leaf nutrients, fruit yield and quality in a mango orchard, it can provide a foundation for reducing chemical fertilizer application in mango orchards. Results indicated that, compared to conventional fertilization, treatments substituting chemical fertilizer with organic manure at different concentrations can reduce the volume weight of different levels of orchard soil and improve soil porosity. The decrease of volume weight and the increase of total porosity in the 0-20cm soil layer were greater than those in the 20-40cm soil layer. Substituting chemical fertilizer with organic manure can improve soil pH and organic matter content in the different soil layers. Although alkali-hydrolysable nitrogen declined compared with conventional fertilization, it did not attain a significant difference. The concentrations of available phosphorus, potassium calcium and magnesium in soils increased compared with the control. All the treatments improved mango yield, however, there was a non-significant effect on single fruit weight. Soluble solid, vitamin C and solidity-acid ratio in fruits all increased, and the titratable acid content decreased compared with the control. Comprehensive comparison indicated that a 30% substitution of organic manure is the most effective treatment to improve soil fertility and fruit quality.
