Ammonification and solid - state fermentation of corn straw in producing feeding - protein 氨化和固态发酵玉米秸秆生产饲料蛋白的研究
2.
In the modern breeding , there are large amount of the excrement to be accumulated , these organic excrement will produce the large amount of ammonia and other harmful nitrogenous substance via ammonification 现代集约化养殖长期累积了大量养殖排泄物，这些有机排泄物经氨化作用产生大量氨等含氮有害物。
3.
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。
4.
The order of four soil biochemical intensity being sensitive to heavy metal pollution indicated as : nitrification > nitrogen fixation > decomposition of cellulose > ammonification . however , soil microbial biomass c : n ratio increased with the increasing of heavy metals level 几种生化作用强度的下降顺序为硝化作用固氮作用纤维素分解强度氨化作用；但土壤微生物生物量碳氮比则随着重金属污染水平的升高而增加。
5.
The contents of organic matters , tn and tp in sediment layer from 0 - 20cm also decreased after 2 months of harvested , but nh / - n and no3 - - n increased due to the amelioration of transperancy and aeration , which accelerated ammonification and nitrification 2个月以后，收割区底泥0 - 20cm深度范围内有摘要机质、 tn 、 tp含量明显下降，收割改善了湿地的通风、透气条件，促进了氨化和硝化作用的发生，使底泥中nh扩一n和n岛一n含量上升。
6.
The respiratory intensity of the contaminated soil decreased by 29 . 93 % while ammonification and nitrification increased significantly than that of control soil . 2 . extraction and purification of soil microbial total dna a method of extracting soil total dna was developed , and it can extract dna from g + bacteria 二、土壤微生物总dna的提取和纯化方法研究为了采用不依赖于培养的16srdna分析的方法研究有机磷农药长期污染对土壤微生物群落结构的影响，建立了从土壤中提取总dna的方法，并通过改进使适合于对革兰氏阳性菌的提取。
