The results showed that they are stemphylium sp , fusella sacc , alternaria sp , fu5ari urn sp , gibberella sp , sphacelia sp , actinomyces , dematium pers 初步鉴定结果分别属于匐柄霉、丛梗孢属、交链孢属、镰孢霉属、赤霉属、蜜孢霉、放线菌属和暗梗单孢霉属。

The results showed that the main microbes in the koji used in naturally fermented liuyang brown bean were mainly molds and bacteria , and less counting of yeast and actinomyces 结果表明：浏阳豆豉自然制曲成熟的曲料中主要微生物为?菌类和细菌类，而酵母菌类和放线菌类数量不大。

The results showed that 5406 actinomyces can improve the wheat seedling ' s height , root system and stalk leaf weight , can increase content of chlorophyll and root system activity in sterilized sand culture 结果表明，经5406放线菌处理后小麦幼苗株高、根长、根体积、根系及茎和叶片干重、叶绿素含量及根系活力均有不同程度的提高。

The results indicated that , the total quanlity of major soil microbes declined , of which the minesoils was decreased by 68 . 43 % ~ 80 . 32 % in the top soil ( 0 - 20cm ) compared with that of the non - minesoils . the proportion of bacteria and actinomyces in the amount microbes decreased , while that of fungi not obviously changed 结果表明：海洲香薷是铜矿区典型的耐铜性植物( elsholtziaharchowensis ) ，植物体中的重金属元素含量表现为cu zn pb cd ， cu与土壤元素的相关性最为显著，其次为zn 。

After analyzing purple soil sampled from neijiang , leshan ofsichuan provinec and yuanmou of yunnan province , the contrast results of microbe quantity feature between surface and subsurface purple soil were obtained as follows . the content of soil organic matter , total and available nitrogen , phosphorous and potassium of surface was higher than subsurface , not relating to the type of purple soil and soil utilization way . the quantity of microbe _ bacteria , actinomyces and mould in surface purple soil was higher than subsurface , which indicated that the organic matter and airy condition in surface soil was more suitable for microbes growing . there was the same tendency in profile change of microbe quantity in purple soil located in temperate _ humid climate of sichuan basin in contrast with dry _ hot climate of yuanmou , yunnan . the nutrient situation of purple soil in sichuan basin shown that state of surface was better than subsurface , while in yuanmou of yunnan the state was on the contrary due to the degradation of surface soil 实验室对四川内江、乐山和云南元谋不同类型紫色土表层和亚表层微生物数量特性的比较分析表明：土壤有机质、氮磷钾全量及其速效量均表现为表层高于亚表层，与紫色土类型和利用方式无关；三大类土壤微生物细菌、放线菌和霉菌数量均表现出表层高于亚表层，表明紫色土表层的有机质和通气性优于亚表层，适宜于这三大类微生物生长；温湿气候条件下的四川盆地和干热气候条件下的云南元谋其紫色土微生物数量的剖面变化具有相同的趋势，唯土壤营养状况在四川盆地紫色土中表现为表层优于亚表层，而在云南元谋紫色土中由于表层土壤的退化作用表现为亚表层优于表层的相反情况。

The results showed in the paddy field the bacteria were predominated , in the dry land the proportion of fungi and actinomyces was distinctly higher than the other two kinds of soil , in the woodland abundant species of basidiomycetes were found ; the natural degradation speed was low , with the degradation the number and composition of microorganisms changed regularly ; when the c / n ratio was adjusted to 25 " ? 1 , the degradation remnant ratio reduced 10 . 67 % than the control 结果表明，水田以细菌为主，旱地中真菌和放线菌数量最多，林地中有大量的高等担子菌；秸秆自然降解较慢，土壤微生物也随着降解的进行而呈现一定的变化规律；当调节c / n比为25 ： 1时，秸秆的腐解残留率比对照组下降10 . 67 。 2

The rhizosphere microflora dynamics of bacteria , actinomyces , fungi and four bacterial physiological groups of kentucky bluegrass under different quality of illumination were studied by adopting selective culture medium to explain scientifically response regular of this grass to different illumination condition 摘要研究了草地早熟禾在不同光照条件下其根际与非根际细菌、真菌、放线菌以及氨化细菌、硝化细菌、好气性纤维素分解菌、固氮菌生理类群的区系动态变化，拟从根际土壤微生物数量变化方面来阐述草地早熟禾对不同光照条件的响应规律。

They are jinfo mountain in nanchuan county ( natural protection section ) , wuling mountain in qianjiang county ( national emphases forest demonstration county which forest cover rate is beyond 50 % ) and zhongliang mountain in beibei county ( artificial destruction is very grave ) . some main land use patterns i . e . woodland , garden , infield , abandon infield , shrub and grassplot are selected in those three sample sites . four aspects on soil fertility index of karst environment under different land use patterns in these three sample sites , are revealed in this paper , by using the field test , indoor measure and analysis , outdoor experiment and field investigation , and the knowledge and technique of soil , ecology , physics and chemistry etc . they are physical characteristic ( effective soil thickness , organic layer thickness , soil texture , water - stable aggregate and soil water etc . ) , chemical fertility ( organism , omni - n , omni - p , omni - k , alkali - nitrogen , available p , available k and rapid available k etc . ) , soil animalcule ( bacteria , fungi , actinomyces and their grosses ) and soil - seed - pool ( plant community diversity index ) in karst ecosystem 本研究以重庆市的南川金佛山(自然保护区) 、黔江武陵山(国家重点退耕还林示范县，森林覆盖率50以上)和北碚中梁山(遭人为破坏严重)典型岩溶区为对象，选择了几种重要的利用方式，包括林地、果园、耕地、弃耕地和灌草坡，采用野外岩溶生态调查和室内试验测量分析相结合的方法，以不同土地利用方式岩溶土壤肥力为重点，对不同土地利用方式土壤肥力特征进行量化分析，找出岩溶土壤肥力差异的主要方面及其根本原因，论文主要从土壤剖面物理退化指标(有效土层厚度、有机质层厚度、质地、团聚体、水分含量等) ，化学肥力退化指标(有机质、全n 、全p 、全k 、碱解n 、速效p和速效k等) ，样地土壤微生物指标(细菌、真菌、放线菌数量及总量)以及样地土壤种子库植物群落多样性等4个方面对重庆典型岩溶区的土壤肥力特征进行了较为详细的分析研究，为岩溶地区士壤资源的合理利用及结构的调控管理提供依据。
