In clover lands, there is decreasing soil organic matter and other nutrients, and soil physical properties are better with lower salinity due to less human disturbance. On other hand, azotobacter of legume increases the available nitrogen content in surface soil.
苜蓿地由于管理粗放，对土壤扰动少，容重较低，孔隙度和毛管孔隙度较高，盐碱度较低；每年对苜蓿的采收显著降低了苜蓿地土壤有机质和养分含量，而豆科固氮菌的存在，使表层速效氮含量较高。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.
前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

By collecting ,testing, comparing, and analyzing the soil samples, soil recovery under the various recovery conditions along Mian CountyNingqiang highway was studied. The results were as follows herbaceous recovery to the soil fertility recovery in the prior was greater than the combination of grass and irrigation or than the pure bushes recovery. In each of them, the content of organic matter were 13.84, 7.50, 6.00 g·kg-1; In the recovery of herbaceous ecology, to grow leguminous plant and granminaceous plant together was better than pure graninaceous plant or pure leguminous plant. In each of them, the content of organic matter was 29.67, 17.51, 9.37 g·kg-1; to sow ryegrass and alfalfa together with some local grass seeds or to grow coxcomb, alfalfa and local couch grass together could bring better effects than to plant the alfalfa only. In each of them the increased organic matter contents were 4.93,17.51 and 9.37 g·kg-1;the quotas of the organic matter and alkaline hydrolysis nitrogen in soil fetility factor were closely connected, mainly because of the difference between the generation quantity and resolution quantity of the organic matter in the soil surface.
采集土壤样品，经室内分析化验，用对比分析的方法对勉县至宁强高速公路生态恢复中不同恢复类型条件下的土壤恢复进行了研究，结果表明草本恢复类型对前期土壤肥力的恢复作用大于草灌结合，并大于单纯灌木恢复类型，其中有机质含量分别为13.84、7.50和6.00 g·kg-1；在草本生态恢复类型中，豆科植物与禾本科植物混播恢复类型大于禾本科植物恢复类型的作用，并大于单纯豆科植物恢复类型的作用，其中有机质含量分别为29.67、17.51和9.37 g·kg-1；黑麦草与苜蓿混播并有当地草种入侵以及小冠花与苜蓿混播并播入当地草种羊茅，明显优于纯苜蓿单播，其中有机质含量分别增加了4.93和3.32 g·kg-1；土壤肥力因子中有机质与碱解氮两个指标有较好的相关性，主要与土壤表层有机质的生成量和分解量之差有关。

The results showed that the total dissoluble proteins hands of 8% and 10% gel were 91 and 97, respectively, and the seed salt soluble proteins bands of 10% gel were 69; All of the five alfalfa species have their own characteristic bands, which are different in number, distribution, width, and concentration; Among three methods, the five species' seed dissoluble protein fingerprints of 10% gel' bands is relatively more, which genetic diversity scattered in A, B and C regions, and can be repeated in different experiments. So it's the best fingerprint. The fingerprints of the seed dissoluble proteins and seed salt soluble proteins of five species are unanimous, which showed that: the hybrid has the nearest genetic distance with Medico go sativa cv.
