| Abstract: | To explore the effects of straw strip mulching on total organic carbon (TOC), dissolved organic carbon (DOC), microbial biomass carbon (MBC) and easily oxidizable carbon (EOC) at different depths of dry land, a straw strip mulching test was set up in Gansu Province druing 2017 to 2020. Treatments included core straw strip coverage (TSM), full black film double furrow coverage (TPM), and traditional open field flat cultivation (TNM) as the control. The results showed that the content of soil organic carbon and activated carbon components decreased significantly with the increase of soil profile depth (P<0.05). TMSM significantly increased the total organic carbon content, soluble organic carbon content and soluble organic carbon content of the 0~20 cm soil layer compared with TPM and TNM. The content of easily oxidizable organic carbon had the same trend in 2019 and 2020. The two\|year average TSM of TOC, DOC and EOC was 16.99%, 67.65% and 155.83% higher than that of TPM, and 8.00%, 31.20%, and 74.30% higher than that of TNM in 2019 and 2020. TSM increased the microbial biomass carbon content of 0~120 cm soil layer. Compared with TPM, the TSM of each soil profile increased by 16.82%, 21.49%, 34.04%, 26.28% and 29.78% on average. Compared with TNM during the two\|year period, the average of TSM increased by 24.83%, 51.32%, 56.72%, 78.94% and 73.42% (P<0.05). In 2019 and 2020,in the 0~20 cm,DOC/TOC and EOC/TOC of TSM were both higher than that of TNM and TPM. MBC in TSM was increased in the 0~120 cm soil profile.A higher MBC/TOC in TSM indicated that TSM increased the content of organic carbon, activated carbon components, activities of the surface soil, and distribution ratio of the carbon component. |
