Abstract

In order to find out the soil fertility status of the major walnut lands and further guide the fertilization management of abundant walnut cultivation in Guangyuan,the individual indicators of soil fertility was diagnosed and evaluated with modified Nemoro Index. The results indicated the soils of major walnut forests in Guangyuan was rich in total N,and the soil pH was generally alkaline;some soils lacked available P,available K,available Fe;most soils lacked organic matter,available Zn,available B,available Cu,available Mn.The soil fertility of walnut forests was generally at low level.Yellow soils lacked available B,available Cu,available Mn.Purple soils lacked available K,available Fe,available Zn,available B,available Cu,available Mn.Yellow soil was more fertile than purple soil.The results suggested to fertilize the soil by increasing the application of organic fertilizer in combination with inorganic fertilizer.
