Other claims from this paper (19)
- Intervention effect Film mulch (M) increased maize grain yield by 89%-105% relative to control.
- Intervention effect Straw plus film mulch (S+M) increased maize grain yield by 93%-136% relative to control.
- Intervention effect Straw incorporation (S) did not change total soil organic carbon concentration relative to control over two years.
- Intervention effect Film mulch (M) did not change total soil organic carbon concentration relative to control over two years.
- Intervention effect Straw plus film mulch (S+M) did not change total soil organic carbon concentration relative to control over two years.
- Intervention effect Film mulch (M) tended to decrease particulate and light organic carbon concentrations in soil.
- Intervention effect Straw incorporation (S) showed a tendency to increase particulate and light organic carbon concentrations in soil.
- Intervention effect Straw plus film mulch (S+M) showed a tendency to increase particulate and light organic carbon concentrations in soil.
- Intervention effect The increase in particulate and light organic carbon under S+M was more pronounced compared with M than compared with control.
- Intervention effect Straw incorporation (S) increased soil microbial biomass carbon relative to control.
- Intervention effect Straw incorporation (S) increased activities of β-glucosidase, alkaline phosphatase and urease relative to control.
- Intervention effect Film mulch (M) increased soil microbial biomass carbon relative to control.
- Intervention effect Film mulch (M) increased activities of β-glucosidase, alkaline phosphatase and urease relative to control.
- Intervention effect Straw plus film mulch (S+M) increased soil microbial biomass carbon relative to control.
- Intervention effect Straw plus film mulch (S+M) increased activities of β-glucosidase, alkaline phosphatase and urease relative to control.
- Intervention effect Under S+M, the increase in soil microbial biomass carbon was more pronounced than under S or M.
- Intervention effect Under S+M, the increase in activities of the three soil enzymes was more pronounced than under S or M.
- Association Activities of β-glucosidase, alkaline phosphatase and urease were positively correlated with soil microbial biomass carbon across treatments and measurement dates.
- Recommendation Introducing maize straw into the film-mulched furrow-ridge system is feasible for a favorable soil organic carbon balance and microbial activity.
