园林废弃物堆肥替代泥炭用于红掌和鸟巢蕨栽培

Use of green waste compost as a peat surrogate in substrates for Anthurium andraeanum and Asplenium nidus cultivation

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p H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。

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.]
