[0018] Example 1 screening can improve the strain of walnut drought resistance
[0019] The rhizosphere soil of relatively dry trees was collected, and bacterial isolates were isolated from various rhizosphere soils by gradient dilution method, and finally 359 strains of bacterial isolates were obtained. The isolated bacterial isolates were numbered after purification. Pick a single colony and transfer it to LB medium for storage on a slant. Four bacterial strains with better growth-promoting effect were obtained by the method of keeping green and increasing the weight of cotyledons of radish. Through further pot experiments of walnuts under different drought stresses, a bacterium suitable for application in arid habitats was finally determined, and its number was L90, and its characteristics were as follows:
[0020] Colony characteristics and cell morphology: L90 formed glossy white colonies after being cultured on LB plates for 24 hours, round and opaque; the surface was ...
