Abstract: Through the pairing method of different generations (1st and 2nd) and ages (8,9,15,18,and 20 years),a comparison of soil microorganisms and the biochemical role for the first and second state of Pinus massoniana plantations was made. Results showed that after successive rotations in young and middle-aged forests,bacteria,actinomycetes,fungi,and total microorganisms for corresponding soil layers were higher in the second generation than the first. Significant (P < 0.05) and highly significant (P <0.01) differences were found in the young forest for bacteria and fungi in the 0-20 cm layer,and total microorganisms in the 0-20 cm and 20-40 cm layers; and in the middle-aged forest,fungi in the 0-20 cm layer and bacteria,fungi,and total microorganisms in the 20-40 cm. Soil microbes in the young and middle aged first and second generation forests were in the order: bacteria > actinomycetes > fungi. The biochemical role for different soil layers,after successive rotations,for the second generation compared to the first,showed higher soil nitrification and lower ammonification in the young and middle-aged forests;also,differences in soil nitrification in the middle-aged forest at the 0-20 cm and 20-40 cm depths was significant (P <0.05) or highly significant (P <0.01). Thus,successive rotations had an effect on soil microorganisms and biochemical roles in the young and middle-aged Pinus massoniana forest.[Ch,4 fig. 2 tab. 18 ref.]
