摘要
为改善和建设炼矿后废弃地的植被恢复及生态环境,研究了炼硫污染地段种植植被后的恢复效果。结果表明,用石灰2 250kg/hm2改土,可降低土壤酸度,提高pH 0.4～0.8;通过大穴施肥增加土壤养分含量,可以增加植株高生长量30%、径生长量30%以上。
The revegetation effect in sulphur-smelting pollution area was studied to improve and construct the revegetation effect and ecotope in derelict land.The results showed that applying 2 250 kg/hm2 could decrease soil acidity and increase pH value by 0.4~0.8.Increasing soil nutrient content by big-bunch fertilization could enhance both the height and stem diameter by 30%.
