摘要: 在冬小麦苗期,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大大高于非根际土壤,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,无机磷细菌主要是假单胞菌属和欧文氏菌属,而非根际土壤的优势解磷菌属不明显。

关键词: 小麦, 根际, 解磷细菌

Abstract: Rhizosphere and nonrhizosphere soils were sampled from winter wheat field at early growing stage.The total number and genus of the bacteria mineralizing lecithin or dissolving phosphate were measured.It was found that phosphobacteria in rhizosphere soil were higher than those in nonrhizosphere soil.However,the organic phosphobacteria were much more than inorganic phosphobacteria either in rhizosphere or nonrhizosphere soil.There were a lot of diverse genera of phosphobacteria in rhizosphere soil,but a few in nonrhizosphere soil.The main organic phosphobacteria were pseudomonas, and advantageous inorganic phosphobacteria were pseudomonas and Erwinia in rhizosphere.However,there were not any advantageous phosphobacteria in nonrhizosphere soil.

Key words: Winter wheat, Rhizosphere, Phosphobacteria
