Abstract:
Investigation of the topsoil nutrients and metal elements in greenhouse soils was conducted in four towns of Shouguang，Shandong Province,in order to provide scientific fertilization for greenhouse soils.The results showed that the top soil nutrients and metal elements in the tested area were rich，while the average contents of pH，C/N，organic matter，total N，available P，K，Ca，Mg，Fe，Zn，Cu and Mn were 6.25，13.96，3.12 g?kg-1，41.25 g?kg-1,1 492.1 mg?kg-1,776.6 mg?kg-1，6 007 mg?kg-1,1 053 mg?kg-1,178.29 mg?kg-1,91.77 mg?kg-1,11.35 mg?kg-1，221.8 mg?kg-1.Meanwhile，the quantity of fertilization should reduce properly to insure environment safety in practice.
