And the culturable bacterial degraders were increased from 10^6CFUg^(-1) soil to 10^8CFUg^(-1) soil after inoculating with the degrader. Moreover, the bacterial population increased faster in 100mgg^(-1) microcosoms than in 500mgg^(-1) microcosoms, revealing that the inoculated bacteria could survive and enhance the biodegradation of chlorophenol in cuntaminated soil.

In order to understand the effect of fertilizer and plant on the microflora remediation in mercury polluted soil, fertilizing and cropping experiments, together with modeling cultivation treatments conditioned non- fertilizing and non-planting, were conducted in a neutral purple soil dressed with different rates of mercury chloride.

以中性紫色土为材料，通过向土壤添加氯化汞的模拟培养试验、施肥试验以及作物栽培试验，研究了汞对土壤中微生物区系和重要微生物生理群繁育的毒害效应。

That is, the appropriate electric field should be a uniform electric field in the strength of 1.0V/cm with the reversal time interval of 10 min in rhizosPHere soil; while the appropriate electric field should be a uniform electric field in the strength of 1.5V/cm in non-rhizosPHere soil.

施加均匀场1.0V/cm的同时，每隔10min切换极性，是土壤根际微生物群落在电场作用下比较合适的电场条件；而对土壤非根际微生物来说，施加均匀场1.5v/cm是相对比较合适的电场条件。

The result indicated that, although microorganism from paddy soil could directly reduce Cr, the reduecing rate and efficiency were limited; the higher Cr concentration was, the less reducing ability the microbial showed; the microbe from different paddy soils had different effects on Cr reducing abilities; The reducing ability of the microbe from Sichuan paddy soil was higher than that from Jiangxi paddy soil. Cr added could be rapidly reduced in paddy soil under anaerobic incubation, moreover, the process of dissimilatory iron reduction of soil could obviously promote the Cr reduction. The existent of Cr could delay the appearance of Fe; the higher Cr concentration was, the later Fe appeared. The delayed time of Fe appearance was in accordance with the ending time of Cr reduction.

结果表明，由水稻土中提取的微生物虽然能够直接还原Cr，但其还原速率和还原程度有限，且Cr浓度越高，微生物的还原能力越差；不同来源的上壤微生物对Cr的还原能力有所差异，其中四川水稻土中微生物对Cr的还原能力均大于江西水稻土；在厌氧培养的水稻土中，添加的Cr可以较迅速地还原，其中土壤氧化铁的微生物还原过程对Cr还原具有明显的促进作用；Cr的存在导致Fe生成的时间出现滞后，目Cr浓度越大生成Fe的滞后时间越长；Fe产生滞后的时间与Cr还原结束的时间具有一致性。

The thin layer of microbiotic crusts with lower bulk density, lower density, higher soil porosity and higher water-holding capacity will markedly influence the soil hydrological processes, such as the processes of penetration, the interception, the redistribution and the evaporation of precipitation, which will threat the soil-water environment in Shapotou area.

容重较小、比重低、孔隙度高和持水性能强的薄层微生物结皮对土壤水文过程产生了深刻的影响。在沙坡头地区，微生物结皮改变了降雨在沙丘土壤中的渗透、再分配、拦截和蒸发等过程，并最终导致固定沙丘土壤水环境的恶化。

Three groups of rhizosphere soil samples of healthy and infected by Verticillium wilt cotton plants were collected from Shihezi cultivated area in Xinjiang, and numbers of microbe, soil nutrients and soil enzymes were measured.

在新疆石河子垦区采集3组棉花健康植株与黄萎病发病植株根际土样，研究其微生物数量、土壤养分、土壤酶等微生物生态特征与棉花黄萎病发病之间关系。

With the increase of establishment years, most of plant communities on the grasslands showed a "V" type change trend in their quantities, i.e., high-low-high, hut the forbs biomass had a "Λ" type change trend and the sedge biomass increased gradually. Soil nutrients presented a "V" type hut soil hulk density presented a "Λ" type change trend, bile soil pH presented a decreasing trend. Most of soil microbial physiological groups and microbial biomass carbon showed a "V" type change trend, phosphorus-dissolving bacteria showed a "Λ" type change trend, denitrifying bacteria decreased gradually, while cellulose-decomposing bacteria showed an increasing trend.

结果表明：随着人工草地建植年限的增加，植物群落的数量特征多呈高－低－高、杂类草生物量低－高－底、莎草生物量增加的趋势；土壤养分变化为高－低－高、容重为低－高－底、pH呈下降趋势；土壤中多数微生物的数量及微生物生物量碳含量的变化为高－低－高，纤维素分解菌数量逐渐升高，而反硝化菌数量逐年下降，溶磷菌数量呈低－高－低的动态变化。

As shown in the experimental results: as the conductor of petroleum biological degradation, the quantity of microorganism is the important factor of petroleum degradation efficiency, the huge natural capacity of microorganism in soil is its foundation of bioremediation; petroleum density in certain scope do not affect for the degradation efficiency of petroleum, and in the density of 5%, its initial degradation efficiency is higher, however after training 40 days, this kind of advantage change weak gradually, the reason may be the petroleum of high density probably having certain poison role for microorganism; the best ecological condition of petroleum contaminated soil bioremediation is that nutrition material C: N = 60, electron receives body HiOi joining quantity amount to 12 mg/g, water content is 50%, surface activator is anion surface activator of 12 Wan base benzene sulphur sour sodium; the relation of primary and secondary of factor is water content, surface activator, nutrition material and electron receiver.

试验研究结果表明：作为石油生物降解的执行者，微生物的数量是影响石油降解效率的重要因素，土壤中微生物的巨大的自然容量是其生物修复的基础；石油浓度在一定范围内对石油的降解效率并没有影响，并且在5％浓度时，其起始降解效率较高，但是到了培养40天以后，这种优势渐渐变弱，可能还是高浓度的石油对微生物有一定的毒害作用；石油污染土壤生物修复的最佳生态条件为：营养物质C：N为60，电子受体H_2O_2的累计加入量为12mg/g，含水量为50％，表面活性剂为阴离子表面活性剂十二烷基苯磺酸钠；因素的主次关系为：含水量、表面活性剂、营养物质和电子受体。
