In 0～20 cm soil layer, there is a considerable effect of herb plant root system on soil anti-shearing strength. Soil anti-shearing intensity (15.33 kPa) by Medicagosativais highest. Particularly in the 20～40 cm soil layer, Melilotus officinalisand M. sativacan drastically enhance soil anti-shearing strength.

试验表明，在0~20 cm土层4种草本植物根系均可显著增加土壤抗剪切强度，其中紫花苜蓿根系对土壤抗剪切强度的增强作用最大，其增大土壤抗剪切强度值为15.33 kPa；草木樨和紫花苜蓿根系在20~40 cm土层也能明显增大土壤抗剪切强度。

In order to discover acid-tolerant Rhizobium meliloti that can nodulate alfalfa high-effectively on acidic soil, researches were explored to isolate rhizobia from alfalfa nodules on acidic soil (pH5.2), methods based on the thesis of adaptive acid-tolerance response of the Rhizobia were adopted, six strains were isolated, which could grow on solid medium with pH4.8 steadily. In addition, the nodulation characteristics, growth curves and mean generation time under different acidity of the strains were examined.

为获得能够使紫花苜蓿在酸性土壤中高效结瘤的耐酸根瘤菌，该研究从酸性土（pH5.2）上生长的紫花苜蓿根瘤中分离到若干菌株，利用根瘤菌对酸的适应性耐受反应筛选到六株能够在pH4.8的固体培养基上稳定生长的菌株，并检测了这六株菌的结瘤特征、不同酸度下的生长曲线和平均代时。

Alfafa is a kind of high protein pasturage, and its development has very important meanings to increase yield of our proteinic forage and urge the transformation of our agricultural structure from the agriculture-economy binary structure to the ternary agriculture-economy-forage structure.

紫花苜蓿是一种高蛋白牧草，发展紫花苜蓿对于增加我国蛋白饲料产量，促进我国农业结构由&粮—经&的二元种植结构向&粮—经—饲&的三元结构转变具有重要意义。

The 0-40cm soil layer soil mean value looked that mixes by the interlacing broadcasts the lawn soil ulmin, the alkaline hydrolysis nitrogen content to be highest; The fast-acting phosphorus, the fast-acting potassium are highest by the unicast awnless brome lawn content; The colleague mixes broadcasts lawn pH to be biggest.

无芒雀麦对土壤要求不严，耐贫瘠、严寒，耐碱性也较强，需氮较多，适宜与紫花苜蓿、沙打旺、野豌豆、百脉根、红三叶等豆科牧草混播，借助豆科牧草固氮作用，促进无芒雀麦良好生长[4]。本实验就是无芒雀麦单播草地和与紫花苜蓿混播草地对土壤理化性质的影响进行比较。

In addition, field experiments were carried to examine influence on lucernes growth, yield and quality by applying calcium and inoculating acid-tolerant R.

并通过田间试验，检测施Ca~(2+)和接种耐酸苜蓿根瘤菌对酸性土上紫花苜蓿生长及产量和品质的影响，以期建立一套耐酸苜蓿根瘤菌筛选和鉴定体系，为在西南紫花苜蓿新种植区接种高效耐酸苜蓿根瘤菌奠定基础。

The results showed that basic application of phosphate fertilizer increased nodulation rate, root nodule number and weight per plant, branch number and hay yield of alfalfa "Gongnong No.1" significantly.
