摘要
采用碎石、草坪、麦秆、木屑作覆盖材料,对树盘进行覆盖,测定土壤温湿度变化,探讨覆盖处理对绿地土壤的影响。结果表明:麦秆覆盖和木屑覆盖能有效调节土壤温度、提高土壤湿度,土壤有机质含量比对照提高56.3%、37.5%,碎石覆盖后的效应与对照(露地)相似,草坪覆盖仅对土壤温度有一定的调节能力。
Impacts of mulch with small stones, turf grass, straws and sawdust were studied by measuring changes in soil temperature, moisture and organic matters. Results showed that mulches of straw and sawdust can effectively regulate soil temperature and increase soil moisture. The content of soil organic matters were increased by 56.3% and 37.5% respectively, the stone mulch was similar to the control （no cover） and the turf mulch merely showed certain effect of regulating soil temperature.
