actinomyces n.【微生物學】放線菌。

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 結果表明,水田以細菌為主,旱地中真菌和放線菌數量最多,林地中有大量的高等擔子菌;秸稈自然降解較慢,土壤微生物也隨著降解的進行而呈現一定的變化規律;當調節c / n比為25 : 1時,秸稈的腐解殘留率比對照組下降10 . 67 。 2

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 本研究以重慶市的南川金佛山(自然保護區) 、黔江武陵山(國家重點退耕還林示范縣,森林覆蓋率50以上)和北碚中梁山(遭人為破壞嚴重)典型巖溶區為對象,選擇了幾種重要的利用方式,包括林地、果園、耕地、棄耕地和灌草坡,采用野外巖溶生態調查和室內試驗測量分析相結合的方法,以不同土地利用方式巖溶土壤肥力為重點,對不同土地利用方式土壤肥力特征進行量化分析,找出巖溶土壤肥力差異的主要方面及其根本原因,論文主要從土壤剖面物理退化指標(有效土層厚度、有機質層厚度、質地、團聚體、水分含量等) ,化學肥力退化指標(有機質、全n 、全p 、全k 、堿解n 、速效p和速效k等) ,樣地土壤微生物指標(細菌、真菌、放線菌數量及總量)以及樣地土壤種子庫植物群落多樣性等4個方面對重慶典型巖溶區的土壤肥力特征進行了較為詳細的分析研究,為巖溶地區士壤資源的合理利用及結構的調控管理提供依據。

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條件下其根際與非根際細菌、真菌、放線菌以及氨化細菌、硝化細菌、好氣性纖維素分解菌、固氮菌生理類群的區系動態變化,擬從根際土壤微生物數量變化方面來闡述草地早熟禾對不同光照條件的響應規律。

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 結果表明,水田以細菌為主,旱地中真菌和放線菌數量最多,林地中有大量的高等擔子菌;秸稈自然降解較慢,土壤微生物也隨著降解的進行而呈現一定的變化規律;當調節c / n比為25 : 1時,秸稈的腐解殘留率比對照組下降10 . 67 。 2

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 實驗室對四川內江、樂山和云南元謀不同類型紫色土表層和亞表層微生物數量特性的比較分析表明:土壤有機質、氮磷鉀全量及其速效量均表現為表層高于亞表層,與紫色土類型和利用方式無關;三大類土壤微生物細菌、放線菌和霉菌數量均表現出表層高于亞表層,表明紫色土表層的有機質和通氣性優于亞表層,適宜于這三大類微生物生長;溫濕氣候條件下的四川盆地和干熱氣候條件下的云南元謀其紫色土微生物數量的剖面變化具有相同的趨勢,唯土壤營養狀況在四川盆地紫色土中表現為表層優于亞表層,而在云南元謀紫色土中由于表層土壤的退化作用表現為亞表層優于表層的相反情況。

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 結果表明:海洲香薷是銅礦區典型的耐銅性植物( elsholtziaharchowensis ) ,植物體中的重金屬元素含量表現為cu zn pb cd , cu與土壤元素的相關性最為顯著,其次為zn 。

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 結果表明,經5406放線菌處理后小麥幼苗株高、根長、根體積、根系及莖和葉片干重、葉綠素含量及根系活力均有不同程度的提高。

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 結果表明:瀏陽豆豉自然制曲成熟的曲料中主要微生物為?菌類和細菌類,而酵母菌類和放線菌類數量不大。

The results showed that they are stemphylium sp , fusella sacc , alternaria sp , fu5ari urn sp , gibberella sp , sphacelia sp , actinomyces , dematium pers 初步鑒定結果分別屬于匐柄霉、叢梗孢屬、交鏈孢屬、鐮孢霉屬、赤霉屬、蜜孢霉、放線菌屬和暗梗單孢霉屬。

The effect of 5406 actinomyces on the growth of wheat seedling were studied 摘要本文研究了5406放線菌對小麥幼苗的影響。
