| 摘 要： | 在甜樱桃砧木落叶期,利用根际和非根际土壤测定分解卵磷脂和溶解磷酸三钙的细菌,发现根际土壤解磷细菌的数量高于非根际土壤,但无论是根际还是非根际土壤,有机磷细菌比无机磷细菌多。根际土壤解磷细菌种类较多,而非根际土壤解磷细菌种类较少。根际土壤的有机磷细菌主要为假单胞菌属,且2种砧木之间根际与非根际解磷细菌种类明显不同。

| Abstract: | Rhizosphere and nonrhizosphere soils were sampled from the Sweet Cherry rootstocks at dormant period.Total number and genus of the bacteria mineralizing lecithin or dissolving phosphate were measured.It was found that the number of either organic or inorganic phosphobacteria in the rhizosphere soil was higher than those in the nonrhizosphere soil.The community structure was much more complicated in the rhizosphere than in the nonrhizosphere.Pseudomonas was advantageous organic phosphobacteria in the rhizosphere.However,the genus was much more different in both of rootstocks. |
