Paper Title:
Study on Diversity of Soil Microbial in Different Reclamation Years
  Abstract

This paper made a comparative study of the distribution and quantity of bacteria, actinomycetes, fungi and different bacteria physiological group in different reclamation years and different soil layers with the soil in different reclamation years as experiment material, adopting flat-panel culture and microbial selecting culture medium and using accounting of gradient plat-panel coating. The results showed that: with the extension of reclamation years, microbial quantities are rising overall. The microbial quantities (bacteria, actinomycetes and fungi) in the cultivated land of 200 years were 4.94 times higher than those in the uncultivated land; the microbial quantities in the surface soil of 200 years were 2.16 times higher than those in the deeper soil. The soil microbial community structure of agricultural land has been changing with the extension of reclamation years and the quantitative relation of the three main microbes was: bacteria > actinomyces > funfi; As the uncultivated land become developed, the microbial diversity index and the quantities of physiological group reduced after increasing in the beginning, but the regularity for change of physiological group diversity index is not obvious.
