1、摘要对14种引种栽培的园林地被植物进行了生物学特性,生态适应性及无性繁殖技术试验研究,以筛选适合银川地区推广应用的园林地被植物种类。研究结果如下:1)引种的14种地被植物分别具有独特的株形、叶色和叶形,花色丰富,花型美丽,花期长,生长旺盛和观赏期相对较长等优点,性状表现良好;具有一定的抗寒性和抗旱性,耐盐碱,耐水湿和耐瘠薄性,能够适应银川地区的地理和气候等环境条件,可以尽快推广应用。2)通过水培试验表明,千屈菜具有较强的耐盐碱性,能够适应银川景观水道的盐碱水浇灌,适宜在景观水道及其它类似盐碱化的地段推广栽培。3)通过扦插试验得出:绣线菊、金红久忍冬和金叶小檗宜采用嫩枝扦插法繁殖,扦
2、插基质宜选用蛭石,结合植物生长调节剂处理插穗,能有效地促进愈伤组织形成和生根,提高扦插成活率,促进植株生长。根据本文研究结果,作者建议在未来银川市城市绿地系统规划中,除了考虑景观效果外,要重点考虑植物与光照,温度,水分,土壤和空气等环境因素之间的互作,科学合理配置植物,构成和谐、稳定、能长期共存的植物生态群落,从而达到丰富植物景观,降低养护成本的目的。关键词:园林地被植物;引种;生物学特性;繁殖AbstractThestudiesonthebiologicalcharacteristics,ecologicaloptimum,clonalpropagationtechnologya
