The effects of grass cultivation and clearing cultivation on the rhizosphere soil,microbial community,and fruit quality of Taoye Cheng
This study used the local characteristic resource Taoye Cheng(Citrus sinensis Osbeck cv.Taoye Cheng)in Hubei Province as the material,and set up two treatments of grass cultivation and clearing cultivation to analyze the effects of grass cultivation and clearing cultivation on the rhizosphere soil,microbial community,and fruit quality of Taoye Cheng.The results showed that the organ-ic matter content in the rhizosphere soil of Taoye Cheng cultivated with grass was 23.53%higher than that of clearing cultivation;in terms of soil nutrients,the content of phosphorus,potassium,calcium,boron,and zinc in the rhizosphere soil of Taoye Cheng culti-vated with grass was significantly higher than that of clearing cultivation,while the content of nitrogen,magnesium,and manganese was significantly lower than that of clearing cultivation.The diversity and abundance of the rhizosphere microbial community of Taoye Cheng cultivated with grass were significantly higher than those of clearing cultivation,indicating that grass cultivation could effective-ly enrich the microbial community of Taoye Cheng rhizosphere.Grass cultivation could promote the growth of Taoye Cheng fruit and the synthesis of vitamin C.Correlation analysis showed that the transverse and longitudinal diameters,single fruit weight,and vitamin C content of the fruit of Taoye Cheng were significantly positively correlated with RB41 and Pseudomonas.
