Abstract

Abstract:

The changes of soil properties of the successive Chinese Fir plantation were studied in Dagang mountain of Jiangxi Province. The result shows that the soil physical properties of young and middle aged Chinese Fir plantations of the 1st generation are better than that of the 2nd generation. Compared the activities of soil enzymes between two generations, the same result, i.e. soil enzyme activities of all the 1st generations are much higher than that of the 2nd generations is showed. Comparing their chemical properties, the result seems irregular during young aged period. Some important soil chemical properties, such as soil humus and soil N, are much higher in the 2nd generations and become regular in the middle aged period. That is, the content of all factors in 2nd generations are much lower than that in 1st generations except the content of available Cu and available Fe.

Key words: Successive rotation, Chinese Fir, Plantation, Soil properties
