But so far , there have not report about forest soil microbe and soil enzymatic activity in westen sichuan . the study ' s object is bitch forest . spruce forest , fir forest , chrysanthemum alp , willow community and two couch grass , so the research of the soil microorganisma , soil enzymatic activity in the subalpine coniferous forests in western sichuan is significant to china . the result shows that : 1 . in the soil , the relativity of the soil microbial puantity is very prominence , the relation with the quantity of the soil microorganism is that : bacillus > actinomyceto > fungi ; the amount of the microorganism of physiological group sequence ranging from high to low is : aminate > bacteriumazotobacter > denitrify bacterium > nitrobacteria > cellulose decomposing bacteria . under the different vegetable community , the microbial quantity is that : s5 > s7 > s6 > s1 > s2 > s4 > s3 其中,各群落中土壤微生物總數以白樺純林( s5 )群落最多,每克干土中的含菌量達66 . 13 10 ~ 6個;其次是冷杉針葉林( s7 )群落,每克干土中的含菌量達43 . 41 10 ~ 6個:第三是云杉針葉林( s6 )群落,每克干土中的含菌量達42 . 85 10 ~ 6個;第四是繡線菊-茅草群落( s1 ) ,每克干土中的含菌量達33 . 83 10 ~ 6個;第五是高山柳群落( s2 ) 、茅草( s4 )群落,每克干土中的含菌量分別為33 . 33 10 ~ 6個和33 . 08 10 ~ 6個;第六是茅草群落( s3 ) ,土壤微生物數量最少每克干土中的含菌量僅為23 . 12 10 ~ 6個。

The population distribution of physiological groups of bacteria , including ammonifying bacteria , denitrifying bacteria , nitrobacteria and nitroso bacteria , organic phosphate dissolving bacteria and inorganic phosphate dissolving bacteria in water body and sediment of suzhou creek are studied with mpn and flat account method from jan . 2002 to mar . 2003 . the role of these physiological groups of bacteria in suzhou creek aquatic ecosystem is discussed 用最大可能數( mpn )法和平板計數法,于2002年1月2003年3月對蘇州河水體和底泥中的主要微生物功能菌群? ?包括有機磷分解菌、無機磷分解菌、氨化菌、亞硝化菌、硝化菌和反硝化菌等進行了生態調查,并分析探討了它們在蘇州河水生態系統中的作用。

The application and development prospect of several microbial preparations such as bacillus sp . , photosynthesis bacteria , nitrobacteria , denitrify bacteria , yeasts and micro - algae which were applied on aquiculture were summarized 摘要簡述了芽孢桿菌、光合細菌、硝化細菌和反硝化細菌、酵母菌等幾種微生態制劑在水產養殖中的應用現狀及發展前景。
