- Abstract
Very few studies are concerned with the medium and long-term soil nutrients of plantations, which often have inconsistent research results. This paper studied the characteristics of the surface soil nutrient changes in two types of plantations with different stand age: 30 years and 60 years. They are needle-leaved plantations (Pinus thunbergii plantation and Pinus densiflora plantation) and broad-leaved plantations (Quercus variabilis plantation). Research results showed: 1) When the stand age is 30 years, the content of organic matters and the nitrogen of the surface soil was presented as follows: Pinus thunbergii plantation>Quercus variabilis plantation>Pinus densiflora plantation, and the content of organic carbon, available phosphate and rapidly available potassium of the surface soil was presented as follows: Quercus variabilis plantation>Pinus thunbergii plantation>Pinus densiflora plantation. Significant differences were found in the content of active organic carbon in the surface soil. 2) When the stand age is 60 years, the content of organic matters, the total nitrogen and rapidly available potassium in the surface soil was presented as follows: Pinus densiflora plantation>Quercus variabilis plantation> Pinus thunbergii plantation and significant differences were found in the content of organic matters and total nitrogen of the surface soil. The content of active organic carbon in the surface soil was ranked as follows: Pinus thunbergii plantation>Pinus densiflora plantation>Quercus variabilis plantation. 3) Among the plantations with 60-year stand age, the content of five nutrients all increased in the surface soil of the Pinus densiflora plantation, namely, organic matters, active organic carbon, total nitrogen, available phosphorus and rapidly available potassium. The content of organic matters, total nitrogen and available phosphorus significantly increased in the surface soil, but no significant differences were found in the surface soil nutrient content of Quercus variabilis plantation and Pinus thunbergii plantation.
