在0.5 hm2废弃钼尾矿库试验区上,采用密植农作物沙障和栽种层埋入田园土技术措施,为耐性植物生长营造了生境小气候,引来了动物微生物改良基质,基本解决了耐性乔灌草植物生长的关键限制因子.研究结果表明,建立沙障比较好的农作物是玉米、高粱和大豆,生长较好的草本植物依次为狼尾草、芦苇、野古草、万年蒿、紫花苜蓿;存活较好的乔灌木依次为辽胡1号杨、辽育三号杨树、辽育一号杨树、荆条和沙棘.试验证明,这种农作物沙障庇护乔灌草生长植被重建新模式初步取得了成本低建立植被的成功,为类似废弃尾矿库重建植被开辟了一条新途径.
In the 0.5 hm2 abandoned molybdenum tailing pond test area, the technology of planting sand barrier and planting layer of close planting crops into the garden soil was adopted to create the habitat microclimate for the growth of the tolerant plants, which brought in the modified substrate of animal microorganisms and basically solved the problem of tolerance The results showed that the better crops were corn, sorghum and soybean and the better-growing herbs were Pennisetum, Phragmites communis, Artemisia annua, Artemisia annua, Alfalfa ; The better surviving trees and shrubs were Liaohu No. 1 poplar, Liaoyu No. 3 poplar, Liaoyu No.1 poplar, Vitex and seabuckthorn. The experiment proved that this crop sands shelter new mode of vegetation regeneration The initial success of the low cost of building vegetation has opened up a new way for the reconstruction of abandoned tailings ponds.
