自生固氮菌 meaning in English
azotobacter
Examples
- The nitrogen fixation in alpine meadow ecosystem is mainly accomplished by anaerobic nitrogen fixing bacteria . both ammonification and nitrification are the highest in 0 cm 10 cm soil depth
从不同植被类型土壤的表层中各生理群菌数的平均值来看，反硝化细菌的数量最高，嫌气性自生固氮菌次之，再次为氨化菌和硝化菌。 - Denitrification and nitrogen fixation in 10 cm 20 cm horizon are higher than those in other soil horizons , in which the partial pressure of oxygen is lower than that in surface horizon , and the number of microorganisms is more than that in below horizon
高寒草甸土壤中未发现有好气性自生固氮菌，但嫌气性自生固氮菌的数量众多。在高寒草甸严酷的自然条件下，嫌气性自生固氮菌为大气氮素固定的主要承担者。 - We mensurate the number of the primary soil microbes such as bacteria , fungi and azotobacter with diluting flat technique , and mensurate the number of cellulose decomposing bacteria with mpn technique , and mensurate the biological quantity of the soil microbes with the technique of chloroform suffocating - inundation culture - colour - compared
本文以长期垄作免耕试验田为研究对象，采用稀释平板计数法测定了土壤中主要的微生物细菌、真菌、自生固氮菌数量，用mpn (最大或然值法)测定纤维素分解菌的数量，采用氯仿熏蒸?淹水培养?纳氏比色法测定微生物生物量。 - The number of mold , bacteria , culturable microorganisms , aerobic nitrogen - fixing bacteria , anaerobic nitrogen - fixing bacteria , aerobic cellulose decomposition microbes , anaerobic cellulose decomposition microbes were the most in 16 - year - old organic tea garden , and the biomass carbon and nitrification of edaphon were also the strongest
霉菌、细菌、可培养微生物总量、好气性自生固氮菌、嫌气性自生固氮菌、好气性纤维分解菌、嫌气性纤维分解菌均以16年生茶园最多，土壤微生物生物量碳和硝化作用也以16年生茶园最强。 - 1 . ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study . little difference in total counts of bacteria , actinomycetes and fungi was observed between the contaminated and the non - contaminated soil . compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil
一、甲基对硫磷长期污染对土壤微生物的生态学效应研究了有机磷农药甲基对硫磷长期污染对土壤微生物的影响，实验表明：土壤细菌、放线菌、真菌总的数量影响不大；自生固氮菌和反硝化细菌数量减少；氨化细菌、亚硝化细菌、硝化细菌的数量在污染土壤中却有所增加；与对照土壤相比，污染土壤呼吸作用下降了29 . 93 ；氨化作用和硝化作用强度得到增强。
