Research advances on soil of pear orchard

China is the largest producer of pear in the world.However,the quality of pear fruits varies largely among different pear producing areas.The research progress on pear orchard soils has been reviewed in this paper in the view of three aspects,viz.,soil nutrient,the effect of soil on the quantity and quality of pear,and soil management.The present paper especially discussed the relationship between pH value,organic matter and calcium content of pear orchard soil in relation to pear quality.On the basis of results,soil covering and fertilizer application were recommended as important measures to improve physical and chemical characteristics of pear orchard soils and increase the quantity and quality of pear.In order to provide technical support for promoting sustainable development of Chinese pear industry,future researches should strength systematic study on pear orchard soil and construct technology system for ecologically-balanced fertilization for pear orchard.
