摘　　要：Different ground mulching treatments were designed to observe the effects on soil moisture content in a second-generation seed orchard of Pinus elliottii. The results showed that： （1） there were extreme differences in soil moisture content Ⅰ and soil moisture content Ⅲ, but no obvious difference in soil moisture content II was observed; and （2） the high-to-low order of soil moisture content Ⅰ under different ground mulching treatments was white film〉sawdust〉black film〉the control, and the highest value was higher than the lowest one by 26.69%; the high-to-low order of soil moisture content Ⅱ under different ground mulching treatments was white film〉black film〉sawdust〉the control, and the highest value was higher than the lowest one by 20.64%; and the high-to-low order of soil moisture content Ⅲ under different ground mulching treatments was black film〉white film〉sawdust〉the control, and the highest value was higher than the lowest one by 26.61%.对不同地表覆盖处理下湿地松二代种子园土壤含水率情况进行了研究,结果表明:1不同覆盖处理之间,土壤含水率I和土壤含水率III存在极显著差异,土壤含水率II差异不显著。2各覆盖处理下土壤含水率I高低顺序为:白薄膜>锯木屑>黑薄膜>对照,且最高值比最低值高26.69%;各覆盖处理下土壤含水率II高低顺序为:白薄膜>黑薄膜>锯木屑>对照,且最高值比最低值高20.64%;各覆盖处理下土壤含水率III高低顺序为:黑薄膜>白薄膜>锯木屑>对照,且最高值比最低值高26.61%。
