Abstract: Investigations were conducted on dynamics of soil ecological characteristics in a bamboo plantation under the 2001—2004 fertilization experiment,which was designed to have six fertilization treatments,i.e.,CK(control),C(organic fertilization carbon),N,NP,NPK,CNPK.The results showed that soil available nutrient pool depleted rapidly,which with the decrease of organ matter by 8.0%,of total N by 5.2% and of available P by 15.0% respectively, under 3-year consecutive cropping without fertilization in bamboo plantation.Fertilizing with C,or NP,NPK,or CNPK could increase the content of organic matter with the following order: C and(N,NP,NPK)(increase by 24.08%)>C(increase by 8.49%)>NPK(increase by 2.28%)>NP(increase by 1.90%).However,if N was fertilized singly,the organic matter would decrease by about 4.06%.The results also showed that balanced C,N,P and K application improved available nutrient content and increased total biomass of the soil,promoted the matter circle in soil,enhanced the potential soil supply and do better to the persistent productivity of shoot bamboo plantation.
