Analysis On Amorpha Rhizobia L. And Their Adaptability Benefits Of Tree Growth

We separated,purified and fostered rhizobia obtained from Amorpha fruticosa L. in bayannor of inner Mongolia in 2009. we investigated the compatibility of growth to the Amorpha fruticosa L, rhizobia,and planted it in the Potted seedlings,we investigated the influence to the growth of Paragenesis wood and the growth of Mixes hands over the wood.The investigation showed that the Amorpha fruticosa L rhizobia has high compatibility of growth, it growed well in NaCl stress at 3% concentration. It can survive in 25~40℃, 30℃benefited its growth best, it could grow at a range of Ph from 5 to 12,ph 7-9 benefited its growth best. The Amorpha fruticosa L Rhizobia displays different resistance to four different antibiotic.The result of experiment indicated that the average hight of Amorpha fruticosa L with rhizobia is 1.78 times to before,the average weight of Amorpha fruticosa L with Rhizobia is 4.41 times to before, the weight of root is 5.35 times to before, 50% of Amorpha fruticosa L has Rhizobia, the total quantity of edaphon in the rhizosphere enhances by 54%; when the Amorpha fruticosa L with rhizobia was hybrided with the clove in the experiment, the average hight of the clove rise by 27.8%, the average weight of clove rise by 23.8%, the weight of the clove root rise by 28.1%,75% of Amorpha fruticosa L has Rhizobia., the total quantity of edaphon in the rhizosphere enhances by 40%. when the Amorpha fruticosa L with rhizobia was hybrided with the Chinese pine in the experiment, the average weight of he Chinese pine rise by 11.1%, the average weight of the Chinese pine rise by 100%, the weight of the Chinese pine root rise by 118.7﹪, 50% of the Amorpha fruticosa L has rhizobia., the total quantity of edaphon in the rhizosphere enhances by 135.2%.
