Study on Growth-promoting Effect of Robinia pseudoacacia Rhizobia on Platycodon gradiflorus
摘要
Abstract
In order to screen out rhizobia strains with obvious growth -promoting effect on Platycodon gradiflorus, we used dif-ferent strains of Robinia pseudoacacia Linn.rhizobia to inoculate P.gradiflorus, and determined the whole -plant length, stem length, root length, whole-plant weight, stem fresh weight and root fresh weight of P.gradiflorus.The results showed that R. pseudoacacia rhizobia strains SLCH171, SLCH023, SLCH184, SLCH091, SLCH034, SLCH145, SLCH079 and SLCH139 had ob-vious growth-promoting effects on the whole -plant length, root length, whole-plant fresh weight, stem fresh weight and root fresh weight of P.gradiflorus, especially SLCH171, SLCH023 and SLCH184 had very significant influences on the agronomic traits and biomass of P.gradiflorus, and these 3 strains could significantly increase the root length , root weight , related biomass and yield of P.gradiflorus.These results could provide a basis for the further development of P.gradiflorus bio-fertilizer.关键词
