Abstract:

Studying the smash riding conservation tillage with green manure on rice filed soil infiltration is playing an importance role in improving the conservation tillage systems on rice field. In order to find out the effect of smash ridging conservation tillage with green manure on rice field soil infiltration in first season and its delayed action, a field experiment was carried out under 2 tillage modes and 4 manuring modes in Guangxi Academy of Agricultural Sciences from 2016 to 2017. The study measured the soil compaction and soil infiltration by SC-900 and single ring after early and late rice harvesting, and used cutting ring to measure the soil bulk density after late rice harvesting. The results showed that smash ridging conservation tillage with green manure had no significant effect on 0-15cm soil compaction, and can reduce plough layer soil compaction. At the same time, smash ridging conservation tillage with green manure can reduce soil stable infiltration rate in first season and second season, which result to soil infiltration capacity fell. Smash ridging conservation tillage with green manure increased soil bulk density and reduced soil porosity, which made soil ramming. Smash ridging conservation tillage with green manure had significantly effect on soil infiltration and soil structure in second season.
