Abstract:
The Allium galanthum planting soil and Capsicum annuum was used as the test material.Potted Capsicum annuum by using the original soil from the planting field of Allium galanthum,the soil from the field of uncultivated crops and the mixed soil with the mass ratio of 1∶1 was carried out,to study the allelopathic effects of Allium galanthum on Capsicum annuum plant and fruit growth,rhizosphere soil microbial and enzyme activities,clarify the effect of soil mediated allelopathy of Allium galanthum on the growth of Capsicum annuum,in order to provide reference for the establishment of the cultivation system of Allium galanthum and Capsicum annuum.The results showed that the allelopathy at lower level of Allium galanthum planting soil accelerate the growth period of Capsicum annuum and significantly promoted the aboveground biomass accumulation,fruit soluble sugar and vitamin C contents,greatly increased the number of soil microorganisms,and significantly promoted soil sucrase and phosphatase.However,the high intensity allelopathy inhibited the aboveground biomass accumulation,leaf chlorophyll content and fruit quality indexes of Capsicum annuum,and reduced the number of microorganisms in rhizosphere.Correlation analysis and path analysis showed that well-coordinated soil microecological environment played an important role in the growth and development of Capsicum annuum.In conclusion,the results showed that the allelopathy of Allium galanthum planting soil could affected the growth and development,and the rhizosphere microenvironment of Capsicum annuum,and showed a ‘low promotion and high inhibition’ effect.
