Root-derived organic carbon is composed of three compartments: root detritus, root eaudates and root symbionts, which represents a large important and potential C sink in forest ecosystems, The known responses of root derived organic carbon and heterotrophic microbes to elevated CO2 were reviewed. Overall, increases in root biomass, productivity, and exudation indicate an augmentation of C inputs into the soil via roots, although changes in root lifespan are still unclear and may modify this flux positively or negatively, Altogether, changes in root chemistry and morphology that may augment soil C storage under elevated CO2 include decreased N concentration and wider root diameter, Alternately, a shift in rooting depth upwards in the soil profile may increase average turnover rates of root detritus. Effects of CO2 concentration on C qualities of root exudates and root symbionts are the least understood components discussed here, Changes of soil heterotropic microbial activity and community under elevated CO2 still remained large uncertainties.

林木根源有机C包括根东通过根枯落物、根系分泌物和根共生菌周转3条途径向土壤输入的有机C，它是森林生态系统中一个重要的、潜在的C汇，综述了根源有机C与其微生物对CO2浓度升高的响应，虽然对根系寿命的变化尚不清楚，但CO2浓度升高将导致根系生物量、生产量、死亡量和分泌物的增加；同时，CO2升高亦促使根共生菌生物量的增加而增加了共生菌的C归还潜力，表明CO2升高使根源有机C的输入增加了，CO2农度升高情况下，根系化学性质和形态特征的这些变化均有利于增加土壤C的吸存；而根分布深度的降低则对土壤C吸存不利；CO2浓度升高对根分泌物和根共生菌质量的影响研究则极少，CO2浓度升高下土壤微生物活性和群落组成的变化存在较大的不确定性，目前CO2浓度升高下林木根源有机C对森林长期C吸存的贡献仍很不清楚。

But after about a month to restore the root system, the leaves of nitrogen, phosphorus and potassium contents in treatment 5, 6, 7, 8, 2 gradually higher than the control. This is because the absorption of fertilizer during this period shown to promote on the elements, and with the passage of time the processing elements continue to be reduced to a leaf until the latter part of the growing season is also higher than the control.3.The pH value in rhizosphere soil of treatments poplar plantation were lower than that in non-rhizosphere soil, but the content of organic,available nitrogen, phosphorus, potassium, utility cuprum and utility zincum were all higher than those in non-rhizosphere soil.

但是经过大约一个月的根系恢复，处理5、处理6、处理7、处理8、处理2叶片中的N、P、K逐渐高于对照，这是因为施肥对元素的吸收在这一期间开始表现出了促进作用，并且随着时间的推移各处理中元素含量持续降低至落叶，直至后期的生长季节也高于对照。3、各处理的杨树林地根际土壤pH值均低于非根际土壤，而有机质、碱解氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤，与其它处理相比，80cm两侧断根施肥处理的根际土和非根际土壤速效养分含量最高，差异达显著水平。

Results: The hairy root was successfully induced and the hairy root culture system was set up; The opines assay was positive for mannopine and agropine; The result of determination showed that there were a lot of anthroquinone constituents in the rhubarb hairy root and the contents of rhein, aloe-emodin, emodin or 8-O-methylchrysophanol were respectively higher than those in wild plant root.

结果：诱导出了天山大黄发根，并建立了发根离体培养系；从发根中检测到甘露碱、农杆碱的存在；定量分析发现，天山大黄发根中含有多种蒽醌类成分，其中大黄酸、芦荟大黄素、大黄素、大黄酚-8-甲醚的含量分别高于原植物根中的含量。

1.2 方法常规开髓揭顶，清理根管，将root zx根管测量仪电极置于被测牙的对侧口角处，探测端接10号k型锉，缓慢进入根管，当测量仪显示到达根尖孔时，用制动片记录其长度，直接摄x线片证实k型锉所到达的位置，确定根管测量仪的准确性。

Or, rather, it employs two ring-shaped half-pipes that rotate with respect to one another (the lower one remaining fixed while the upper one revolves along with the building). The joints between the half-pipes have rubber seals to stop the contents leaking, and each half-pipe has a vertical pipe connected to it, to introduce or dispose of the fluid concerned.

或者更确切的说，它使用了两根彼此旋转的环形半管（当上面那根独自围着建筑旋转的时候，下面那根余下的部分被固定），两根半管的接头有橡胶防止泄漏，每根半管都有一根垂直管与之相连，引入或排出附着的液体。

This study focused on the distribution features of four protozoa in corn rhizosphere and nonrhizosphere soils. The total number of the four protozoa in rhizosphere soil was about 1.6 times of that in nonrhizosphere soil at 52 days after sowing. However, there is no significant rhizosphere effect at other growing periods of corn.

通过调查玉米根际和非根际土壤中4种原生动物的动态分布发现：仅在玉米抽雄时期，根际土壤中4种原生动物总数是非根际土壤中的1.6倍，而在其它生育时期没有显著的根际效应。
