Abstract
[Objective] Effects of several factors like pH and temperature on activity of Paenibacillus polymyxa DN-1 and decreasing digestion rate of DN-1 strain by validamycin A were studied to provide reference for improving biological activity of DN-1 strain.[Method] We investigated the effect of pH,temperature and environmental factors on the inhibitory effect of Paenibacillus polymyxa DN-1,and determined effect of validamycin A on digestion rate of DN-1.[Result] When pH was from 6.0 to 8.0,the DN-1 strain had good inhibitory effect on Rhizoctonia solani;when the pH was 7.0,the DN-1 strain had the best inhibitory rate.When the temperature was from 15 ℃ to 40 ℃,the DN-1 strain showed strong inhibitory effect on Rhizoctonia solani;when the temperature was 35 ℃,the inhibitory effect was the strongest.Adding different proportions of DN-1 strains with the agent of validamycin A had reduced digestion rate of Bacillus.[Conclusion] Both temperature and pH have effect on inhibition of the DN-1 strain to Rhizoctonia solani,and validamycin A can prolong the shelf life of biological pesticide containing DN-1.关键词
