Effects of Different Microbial Agents on the Growth of Pepper Seedlings
In order to explore the effects of microbial agents on the growth of pepper seedlings,this study took pepper"Chuangjiao No.1"as the test material,and added three kinds of microbial agents in the self-developed universal seedling substrate,respectively.The indicators of fresh weight,plant height,stem diameter and rhizosphere microbial content of pepper seedlings were measured.The results showed that the fresh weight and plant height of pepper seedlings increased significantly after adding Bacillus subtilis compared with control.The bacterial con-tent of rhizosphere soil could be increased by adding three kinds of microbial agents.The content of actinomycetes in rhizosphere soil could be increased by adding Warbo compound bacteria and Bacillus subtilis.The results showed that Bacillus subtilis was the best of the three microbial agents,which could significantly increase the fresh weight and plant height of capsicum,and increase the content of bacteria and actinomycetes in rhizosphere soil of pepper,which was of great significance for promoting the growth of pepper seedlings and the sustainable development of agriculture.
