摘要: 为促进园林废弃物资源化利用,将改良后的园林废弃物堆肥分别以0%,20%,40%,60%,80%,100%替代泥炭进行红掌Anthurium anaraeanum和鸟巢蕨Asplenium nidus栽培研究。该研究共设6个处理3次重复。结果表明:园林废弃物堆肥的添加显著提高栽培基质容重、持水孔隙,降低了总孔隙度、通气孔隙(P<0.05);园林废弃物堆肥的添加显著降低基质有机碳质量分数(P<0.05),提高基质pH值、电导率值、营养元素质量分数(P<0.05);鸟巢蕨栽培中,以添加园林废弃物堆肥60%~80%效果明显,植株鲜质量、株高、冠幅、叶绿素质量分数分别提高11.91%~51.18%,4.09%~5.12%,31.72%~43.08%,18.06%~14.84%(P<0.05);红掌栽培中,以添加园林废弃物堆肥60%效果最好,鲜质量、株高、冠幅,叶绿素质量分数分别提高27.00%,23.74%,13.05%,10.15%(P<0.05)。园林废弃物堆肥可以部分替代泥炭用于红掌和鸟巢蕨栽培。图2表3参15Abstract: This study examined the possibility of using modified green waste compost (GWC) as a cultural substrate component for growth of Asplenium nidus and Anthurium andraeanum. Culture substrates were prepared by mixing modified GWC and peat at the volumn rates of 0% to 100%, 20% to 80%, 40% to 60%, 60% to 40%, 80% to 20%, and 100% to 0%. The study was conducted by 6 treatments, each with 3 replications. Results showed that GWC in the culture substrates increased bulk density and water-holding porosity(P<0.05 according to LSD test), but decreased total porosity and aeration porosity(P<0.05 according to LSD test). In most cases, GWC in the culture substrates reduced the organic carbon content(P<0.05 according to LSD test) and increased pH, electrical conductivity, and nutritive elements(P<0.05 according to LSD test). Compared to a peat control group, the most Asplenium nidus plants were obtained from 60% and 80% GWC-based substrates with increased fresh weight (11.9%-51.2%), plant weight (4.1%-5.1%), canopy (31.7%-43.1%), and chlorophyll (18.1%-14.8%)(P<0.05 according to LSD test). Also, compared to a peat control group, the most Anthurium andraeanum plants were obtained from 60% GWC based substrates with increased fresh weight (27.0%), plant weight (23.7%), canopy (13.1%), and chlorophyll (10.2%)(P<0.05 according to LSD test). The findings suggest that green waste compost can replace partly peat surrogate in substrates for Anthurium andraeanum and Asplenium nidus cultivation. [Ch, 2 fig. 3 tab. 15 ref.]
