Screening of Rhizosphere Nitrogen Fixing, Phosphorus and Potassium Solubilizing Bacteria of Malus sieversii (Ldb.) Roem.

Description

Eight populations of organic phosphorus solubilizing bacteria (oPSB) (56), inorganic phosphorus solubilizing bacteria (iPSB) (13), NFB (22), and KSB (24) were isolated from eight populations of Xinjiang wild apple rhizosphere in Ili by medium culture. Their morphological characteristics were recorded and their activity was determined.The L16 (45) orthogonal experiment, which used the three strains as testing materials, was created to assess the effects of the strains on apple physiological indicators, soil nutrients, leaf nutrients, and biomass, as well as to identify the ideal combination, concentration, timing, and application method.
