【摘要】 利用广州天湖的气候和地理特点,通过不同基质、不同种植密度以及2层种植方式仿野生栽培金线莲组培苗。结果表明,采用泥炭土和珍珠岩混合基质移栽金线莲组培苗成活率可达到93.33%;以800株/m~2为适宜的生产种植密度;双层种植时,单位面积鲜品产量是单层种植时的2.01倍,单位面积干品产量是单层时的2.09倍,可作为仿野生栽培金线莲的种植模式。仿野生栽培试验明确了该地区常绿阔叶林下种植金线莲的可行性,有利于天湖金线莲原生种的保护和开发利用,在维持原生态的同时可有效提高土地资源的利用率。更多还原

【Abstract】 Utilizing the climate and geographical features of Tianhu Lake in Guangzhou, the feasibility of planting Anoectochilus Roxburghii under evergreen broad-leaved forests in this area was confirmed. The plantlets of Anoectochilus Roxburghii were planted by different substrates, different planting densities and two-layer planting methods. The results showed that the survival rate of Anoectochilus Roxburghii could reach 93.33% when they were transplanted with peat soil and perlite, the appropriate planting density was as 800 plants/m~2, and the yield of fresh products per unit area with twolayer planting methods was 2.01 times higher than that of single-layer planting, and the yield of dry products per unit area wass 2.09 times higher than that of single-layer planting. The bionic cultivation results concluded that there esxits feasibility of planting Anoectochilus roxburghii in Tianhu Lake in Guangzhou. The production technology is conducive to the protection and utilization of Anoectochilus Roxburghii, and raising the land use rate without environmental damage.更多还原
