辽西半干旱区尾矿废弃地不覆土植被恢复技术研究

Vegetation Restoration Technique Without Covering Soil in Abandoned Tailing Land in Semiarid Western Liaoning

对辽西半干旱区尾矿废弃地不覆土造林技术进行了研究,并与覆土造林地进行了对比试验。结果表明:不覆土造林地植物生长正常,经过4年的植被恢复,覆土与不覆土养分含量在0.05水平上差异不显著,栽植3年后,其生长量趋于一致。

Forestation techniques on soil-uncovered abandoned tailing land in semiarid western Liaoning were studied. Soil- covered forestation area were compared with the soil-uneoverd forestation area. Result shows that plant grow normally on soil-uncovered forestation area;the soil nutrient content of soil-covered ＆ soil-uncovered area which are both at 0.05 level have little difference after 4 years of vegetation recovery;plant growth tends to be the same level after 3 years.
