摘要
以山西省古县为研究地,比较分析了5种覆盖措施下2年生五角枫幼苗造林后的土壤含水量变化及苗木生长情况。结果表明,3次降雨后,各覆盖措施的土壤含水量均高于对照,从大到小依次排序为土中覆盖枯草>纸板覆盖>地膜覆盖>碎石片覆盖>地表覆盖枯草。各覆盖措施各月份的平均土壤含水量均高于对照,从大到小依次排序为土中覆盖枯草>纸板覆盖>PE地膜覆盖>碎石片覆盖>地表覆盖枯草。总体来看,土中覆盖枯草处理的蓄水保水效果最好,土壤含水量降低速率最慢,苗木成活和生长情况也较好。
Taking Gu County in Shanxi Province as the research site,the changes in soil moisture content and seedling growth of 2-year-old Acer mono seedlings after afforestation under 5 coverage measures were compared and analyzed.The results showed that the soil moisture content of each coverage measure after 3 rainfalls was higher than that of the control which sort in descending order as soil covered with dry grass>cardboard covered>plastic film covered>gravel covered>surface covered with dry grass.The average soil moisture content of each coverage measure in each month was higher than that of the control which sort in descending order as soil covered with dry grass>cardboard covered>plastic film covered>gravel covered>surface covered with dry grass.Overall,the treatment which soil covered with dry grass had the best water storage and retention effect,and the rate of soil moisture reduction was the slowest.
