Abstract:
To explore the application effect of plant growth promoting rhizobacteria(PGPR) Paenibacillus polymyxa G15-7,NSY50 and Pseudomonas chlomraphis HG28-5 on cucumber in greenhouse production,‘Bojie 605’ cucumber was used as the experimental material，and bacterial liquid root irrigation method was used to study their effects on cucumber plant growth，fruit quality and rhizosphere soil environment，so as to improve cucumber soil environment and promote its growth.The results showed that the three strains could improve the growth of cucumber plants，the chlorophyll content and root activity，and the fruit nutritional quality，the activities of sucrase，urease，phosphatase and peroxidase in rhizosphere soil，the number of bacteria and actinomycetes in rhizosphere soil and the content of available nitrogen，phosphorus and potassium in rhizosphere soil.Among the three strains，G15-7 had the best treatment effect and had certain potential for development and utilization.
