【摘要】 以宽叶雀稗(Paspalum wettsteinii)、百喜草(P. notatum)、狗牙根(Cynodon dactylon)和猪屎豆(Crotalaria pallida) 4种植物种子为材料，研究其在沙土、园土、红壤、建筑废弃土、碎石块等基质中萌发和幼苗生长情况，筛选4种植物最适栽培基质，以期为电网基塔下及四周裸露地面复绿提供指导。结果表明，沙土适于宽叶雀稗、百喜草、狗牙根种子发芽；猪屎豆在5种基质中均不发芽。宽叶雀稗适于红壤生长；百喜草、狗牙根适于园土生长；宽叶雀稗为沙土、建筑废弃土和碎石块上最适合栽种的植物。通过灰色关联度分析，3种植物苗期生长的综合排序为δ宽叶雀稗(0.553)> δ狗牙根(0.522)>δ百喜草(0.436)，故在5种基质中，宽叶雀稗幼苗生长综合表现最佳。更多还原

【Abstract】 In order to provide theoretical basis and practical guidance for green restoration of exposed ground under and after excavation, germination and growth among Paspalum wettsteinii, P. notatum, Cynodon dactylon and Crotalaria pallida in sand soil, garden soil, red soil, construction waste soil and gravel were compared, to find out the best substrate of each plant. Results showed that sand soil was the most suitable material for germination of P.wettsteinii, P. notatum and Cynodon dactylon, Crotalaria pallida couldn’t sprout in five soil substrates. Red soil was the best substrate for P. wettsteinii. P. notatum and Cynodon dactylon both grew best in garden soil. The best plant to grow on sand soil, construction waste soil and gravel was P. wettsteinii. The comprehensive of seedling growth of the three plants was δPaspalum wettsteinii(0.553) > δCynodon dactylon(0.522) > δP. notatum(0.436), which were evaluated with the gray relational analysis method. P. wettsteinii grew best in these five substrates.更多还原
