Abstract Soil moisture and physical characteristics strongly influence plant-available water and surface crust strength, which affect seedling emergence. We test interactions between rainfall amount and topsoil and waste rock blends and their impact on restoration outcomes in a semi-arid environment. Seedling emergence was evaluated in eight species across three winter rainfall treatments (low (ambient) 68 mm, equivalent to 1st decile; median 144 mm; and high 182 mm, 8th decile) and three soil cover treatments (topsoil, waste rock and topsoil+waste rock blend (3:1)) to assess the effect of rainfall amounts, soil cover blend, and their interactions on plant recruitment in restoration. Seedling emergence for all species was

土壤覆盖和降雨之间的相互作用影响半干旱带状铁地层的采矿后植物恢复

摘要 土壤水分和物理特性强烈影响植物可利用水和地表地壳强度，进而影响幼苗的出苗。我们测试了降雨量与表土和废石混合物之间的相互作用及其对半干旱环境中恢复结果的影响。在三种冬季降雨处理（低（环境）68 毫米，相当于第 1 十分位数；中值 144 毫米；高 182 毫米，第 8 十分位数）和三种土壤覆盖处理（表土、废石和表土 +废石混合 (3:1)) 以评估降雨量、土壤覆盖混合及其相互作用对恢复中植物补充的影响。所有物种的幼苗出现是
