It has been 40 years since dobereiner and ruschel isolated the nitrogen - fixing bacteria from the rhizosphere of sugarcance plants and demonstrated the potential of diazotrophs to associate with graminaceous plants . more recent evidence of significant biological nitrogen fixation in economical important graminous species , particularly sugar cane , rice and forage grasses , has induced tremendous interest in ni fixation by non - legumes 本研究分離、篩選得到一株固氮酶活性高且穩定，生長勢強的聯合固氮菌株，并對其分類地位、形態及生理特征、對環境的適應性及其對植物的促生效果和作用機理作了系統研究，得結果如下。

Results demonstrated that increases in biomasses of butachlor - degrader in crops rhizosphere soils were the principal cause of facilitations of butachlor degradation , and biomasses of butachlor - degrader varied markedly among various crops rhizosphere soils and resulted in the difference in facilitations of butachlor degradation among various crops 根際土壤中了草胺降解菌塵物量的提高是丁浙江人學幀卜學位論義4草胺加速降解的主要原回，不同作物恨際上壤中丁草胺降解菌生物量的差異導致對丁草胺降解促進程度不同。

The results showed that the treatment of oxygen supply in the rhizosphere increased significantly the eh of soil and the dry matter production of the organs , promoted early tillering , and increased the productive panicles per plant , primary branches and grains per panicle , resulting in a markedly hither grain yield ( 8 . 8 % more than that of the ck ) 結果表明，與淹水處理相比，根際供氧能提高稻田土壤氧化還原電位，提高各器官的干物重，促進分蘗早發，增加有效穗數、一次枝梗數和每穗實粒數，具有顯著的增產效果。

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。

In this study , 5 rhizosphere soil samples of wheat , maize , ryegrasses and willow tree were collected from campus of china agricultural university and beijing chaoyangqu , respectively . a total of 29 isolates were selectively obtained from these rhizosphere soli samples based on their growth on nitrogen - free medium and their resistance to 100 for 10 - 15 min 本文在中國農業大學科學園區采集了小麥和玉米的根際土，從北京市朝陽區洼里分別選擇不同環境采集2個黑麥草根際土壤樣品和1個柳樹根部的土壤樣品，分別從這5個土壤樣品中分離固氮的芽孢桿菌。

The results showed that quantity of bacterium and four bacterial physiology groups was positively correlated with quality of illumination ; their quantity showed a reduced tendency with the reducing of the illumination condition , but quantity of fungi was negatively correlated , it was increased gradually with the reducing of the illumination condition ; rhizosphere soil of kentucky bluegrass turned into fungi type from bacterium type ; the rhizosphere effect of various bacterial physiological group of kentucky bluegrass is obvious under different quality of illumination 結果表明，草地早熟禾根際細菌及四類細菌生理群數量與光照條件呈正相關，隨著光照條件的減弱，其數量呈降低趨勢；根際放線菌數量隨光照的減弱呈先下降后上升的趨勢；而真菌數量與光照條件呈負相關，隨著光照條件的減弱，根際真菌的數量逐漸增加；草地早熟禾根際土壤由“細菌型”向“真菌型”轉化；不同光照條件下，根際各微生物類群都表現出明顯的根際效應。

The number of 3 rhizosphere microorganisms ( bacteria , fungi , actinomycete ) and 5 enzyme ( catalase , protease , urease , phosphatase , invertase ) activities were studied during the whole life of corn plant in sandy loam , loam and clay soil textures . [ method ] using yedan22 , the number of 3 rhizosphere microorganisms and 5 enzyme activities with different textural soils were investigated in a pond 摘要目的明確不同質地土壤（砂壤、中壤、重壤）玉米生育期間根際微生物（細菌、放線菌、真菌）數量與酶（脲酶、蛋白酶、磷酸酶、轉化酶、過氧化氫酶）活性的變化。

The research results indicated that the ecological effect of rice rhizosphere microbes was not only affected by water regime and nitrogen fertilizer separately , but also affected by the mutual effect of the two factors , in general , n had a dramatic effect in the tillering stage , water regime produced little in the booting stage , during the rice riping stage , the rice was not only affected by water condition and n , but also affected by mutual influence 氮素因子一般在水稻生長的分蘗期就對水稻根際土壤微生物生態效應有顯著影響，到孕穗期，水分條件開始起作用，在成熟后期，水稻不僅受到水分條件和施氮的影響，同時還受到水分條件和施氮的交叉作用影響。

Degradation dynamics of the herbicide butachlor were investigated in nonrhizosphere soil , and various crops rhizosphere soils with or without inoculation treatment . the population dynamics of the cultureable microorganisms capable of utilizing butachlor as sole c and energy source were estimated with most probable number method in the process of butachlor degradation 本文考察主要作物棉花、小麥、玉米、水稻等作物根際土壤、接種后根際土壤和非根際土壤中除草劑丁草胺的降解速率，同時采用最大可能數( mpn )法測定分析丁草胺降解過程中丁草胺降解菌的變化動態。

Ions ( mainly refering to ca2 ' , mg2 * and ncv et al . , which have higher concentration in soil solution ) in rape rhizosphere with no re and appropriate dose re treatments moved mainly via a diffusion process up to a 3mm distance from the central compartment ( c . c ) , and mainly by mass 油菜對照和低濃度稀土處理距根表3mm以內離子（主要指ca 》 、 no 。 w等在土壤溶液中濃度較大的離子）遷移以擴散方式為主， 3mm以外的區域則以質流方式為主。

2 . in rhizosphere culture experiment , re applications with appropriate dose in three weeks significantly increased the biomass ( dry matter ) of rape and rice , and the effects of re on the rape was better than the rice , but they decreased or became little significant in eight weeks 根際培養條件下，第三周低濃度稀土處理顯著提高油菜和水稻的生物量(以干物重計) ，對油菜的作用效果優于水稻，第八周作用趨緩或不明顯。

( 3 ) compared to young stand of the first rotation of larix olgensis , activity acidity ( ph value ) , organic matter content , humus component content , moisture , and total porosity in rhizosphere soil of the young stand of the second rotation of larix olgensis decreased ( 3 )二代落葉松幼齡林與一代落葉松幼齡林相比，根際土壤活性酸( ph值) 、有機質含量、腐殖質組成、土壤水分含量和總孔隙度降低。

The planting of crops amend the root - zone environment and augmented the depletion of butachlor in various crops rhizosphere soils and crops rhizosphere soils with inoculation conduced to enhance degradation of butachlor in soil . it could be dr 試驗結果表明，植物根際是實現農藥快速降解的微環境，在作物根際土壤接種降解菌可以強化農藥的降解作用，是實現污染治理的一種有效途徑。

Mongolica , soil acidity , humus component content , available k , total p , organic p , inorganic p , enzyme activity , and microbe amount of young stand olgensis of the second rotation of larix olgensis in non - rhizosphere soil also 不同發育階段影響林木生長量的主要養分因子是土壤有機質、速效鉀、水解氮以及土壤磷形態的全磷、有機磷、無機磷總量、有效磷、 ca一p和fe一p 。

Rhizosphere is the environment that roots directly confronted , which is quite different from the common soil because of the interference of roots , so tree roots had the effect of inhibition on phosphorus immobilization to a certain extent 林木根系生長所形成的土壤環境能在一定程度上減少土壤對磷的固定，增加了磷的有效性。加磷量不同的各土壤對磷的吸附作用不同。

The roots of many wetlands and aquatic plants species are able to release oxygen and / or oxidant into the rhizosphere , resulting in the precipitation of iron and manganese oxides at the surface of roots , also referred to as fe - plaque in the case of fe 摘要許多濕地、水生植物根系都具有向根際環境釋放氧氣和氧化物，在根表和根際形成鐵、錳氧化物膠膜的能力。

The new addition of cyaneus in actinomycetes group in rhizosphere soil and non - rhizosphere soil may be fundamental reason for the second rotation effect . ( 4 ) compared to the young stand of pinus sylvestris var 二代林放線菌類群中具有蘭色類群和玫瑰紫亞類，樟子松林則沒有，而樟子松林土壤具有的放線菌中的金色類群和綠色類群，二代林則沒有。

It was indicated n split supply has an accumulated ecological effect on the rice rhizosphere microbes activities , so does water factor on the soil microbes of rice rhizosphere 這說明在分次施氮的施肥模式下，施氮對水稻根際土壤微生物的生態效應保持一定的持續作用，而水分條件對土壤微生物的生態效應也需要一定的時間才能起作用。
