摘 要：
为促进绿化废弃物和牛粪的资源化利用,采用赤子爱胜蚯蚓Eisenia fetida对绿化废弃物和牛粪的混合物进行好氧-蚯蚓结合堆肥处理。在绿化废弃物好氧堆肥60 d后,按0(T1),2%(T2),4%(T3),6%(T4),8%(T5),10%(T6)的质量分数在绿化废弃物中添加牛粪,并加入蚯蚓,继续蚯蚓堆肥60 d,以无牛粪无蚯蚓的绿化废弃物堆肥作为对照(T0),最终将堆肥产品用作基质进行美丽竹芋Calathea veitchiana栽培试验。结果表明:蚯蚓堆肥处理(T1~T6)产品在营养元素含量和美丽竹芋生长量上显著高于对照(T0)。不同蚯蚓堆肥处理中,绿化废弃物与牛粪混合处理在蚯蚓存活率、蚯蚓生长和繁殖速度、纤维素和木质素降解率、堆肥产品营养元素含量及细菌、真菌和放线菌数量,以及美丽竹芋生长(株高、冠幅、叶片数、鲜质量)上均显著高于纯绿化废弃物处理(T1)。在绿化废弃物与牛粪混合处理(T2~T6)中,添加质量分数8%(T5)和10%(T6)牛粪的处理在蚯蚓生长量、繁殖率、产品质量指标和美丽竹芋生长指标上优于其他处理。可见,利用好氧堆肥-蚯蚓堆肥结合处理方式可以有效应用于绿化废弃物处理,其中以添加质量分数8%(T5)和10%(T6)牛粪的处理效果最佳。

摘 要：
To accelerate the resource utilization of green waste, this study considered the combination of composting disposed green waste mixed with cow dung by employing Eisenia fetida. After pre-composting green waste for 60 d, seven treatments were prepared for vermicomposting by mixing green waste(pre-composted materials) with cow dung at ratios(dry weight) of 0(T0, without earthworms as a control), 0(T1), 2%(T2), 4%(T3), 6%(T4), 8%(T5), and 10%(T6). Growth and reproductive performance of E. fetida in different treatments were measured after 60 d of vermicomposting with a plant cultivation experiment(Calathea veitchiana) being conducted to estimate the quality and maturity of the final vermicompost. A complete random design with treatments of T0, T1, T2, T3, T4, T5, T6 and 30 replications. At the end of cultivation, five plants were randomly selected from each treatment and were analyzed for the plant growth parameters. Results showed that final products of all treatments with earthworms(T1-T6) were significantly higher(P<0.05) in nutritional element content and plant growth parameters than T0. Moreover, in comparison with pure green waste treatment(T1), treatments with the addition of cow dung significantly(P<0.05) increased the rate of growth and reproduction of earthworms, significantly(P<0.05) accelerated the degradation rate of cellulose and lignin, and significantly(P<0.05) increased nutrient contents of the final vermicompost product. Moreover, with the addition of cow dung, significantly(P<0.05) increaseed in microbial population(bacteria, fungi, and actinomycetes) in vermicomposts were recorded. Among treatments T2-T6, T5 and T6 had significantly(P<0.05) higher fertilizer value for the final product as well as significantly(P<0.05) higher growth and fecundity of E. fetida. Thus, the combination of both processes(composting + vermicomposting) could be suitable for disposing cow dung and green waste with the green waste mixed with cow dung treatments at rates of 8%(T5) and 10%(T6) improving the efficiency and quality of the vermicompost.
