摘要 石质边坡的生态修复是目前国内外生态环境建设的一大难题。近年来,国内外将喷播技术用于石质边坡的植被恢复,取得了较好效果。以水泥为基质,研究了其不同配比量对植物种子发芽及幼苗生长的影响。结果表明:当用水泥作为粘合材料的喷播基质时,随着水泥含量的增高,草种的发芽率逐渐降低,幼苗生长较差。在用低量水泥作为粘接材料基质种植狗牙根、高羊茅和多年生黑麦草时,能基本成坪。基质中的4%水泥含量是临界点,4种草种在水泥含量〉4%的基质中生长均受到明显抑制。 The ecological restoration of stone slope was a difficult problem of ecological environment construction at home and abroad.The spray seeding technique was used in the vegetation restoration on stone slope in recent years,which had a good effect.Using cement as the adhering material,the effects of different contents cement on the seed germination and seedling growth were studied.The results showed that the germination rate of grass decreased and the seedling could not grow well with the increasing of cement content.The turf could be formed with bermuda grass,tall fescue and perennial ryegrass when the cement content was low.The critical value of cement content was 4%,and the growth of all grasses was inhibited with more than 4% of cement.
