Abstract:: In order to study the effects of cash crops on soil organic carbon in rhizosphere, two different types of alder were used to study their effects on soil carbon of rhizosphere. The results show that:(1)different types of Aralia affect the content of soil organic carbon in the rhizosphere; soil organic carbon in rhizosphere of Small-leaf type of alder was the highest, followed by big lea, it is the lowest the control group;(2)the type of alder affects the activities of urease, sucrase and peroxidase in the rhizosphere, activities of enzymes in the rhizosphere of the small leaf type of alder are higher than those in the large leaf type of alder;(3)the highest microbial respiration was found in soils of small-leaf alder, followed by large leaf alder, the microbial respiration of the control was the lowest;(4)soil microbial respiration is significantly related to soil urease and bacterial counts, and the correlation coefficients are 0.65 and 0.61, respectively; soil inorganic carbon content showed negative relation to soil microbial respiration, the correlation coefficient is -0.67; soil organic carbon content and microbial respiration presented marginal significance(p=0.06). These results indicate that the increase of soil carbon income in rhizosphere can be taken as a reference index in the future breeding, which can provide the scientific basis for the development of low-carbon agriculture.
