【摘要】 为了探讨播量和有机肥对高寒矿区人工建植植被生长状况的影响，以及无纺布处理对土壤温湿度的影响，试验采用播量与有机肥两因素完全随机区组设计，对不同播量及有机肥处理下植被的生长状况及不同月份下土壤温湿度进行了观测研究。结果表明：(1)2 kg/m~2的有机肥+30 g/m~2的播量处理下(M2S3)植被高度、盖度、地上生物量及植物分蘖数均有所提升。(2)无纺布覆盖对渣山表层土壤具有明显的保温作用，平均增加土壤表层温度1.69℃(P<0.05),对土壤湿度影响不明显(P>0.05)。更多还原

【Abstract】 In order to explore the effects of seeding and organic fertilizer on the growth of artificial vegetation and non-woven fabric treatment on soil temperature and humidity in alpine coalmine area, the experiment adopted a completely randomized block design with two factors of seeding rate and organic fertilizer.The growth status of vegetation under the treatments, soil temperature and humidity in different months were observed and analyzed.The results showed that:(1)Under the treatment of 2 kg/m~2 organic fertilizer +30 g/m~2 sowing amount, the vegetation height, coverage, above-ground biomass and the number of tillers increase.(2)Vegetation and non-woven covering have a certain thermal insulation effect on the surface soil of the mining area.(3)The soil surface temperature under the non-woven covering treatment significantly increases by 1.69 ℃(P<0.05).更多还原
