| 中文摘要 | 蚓糞堆肥含有許多植物生長所需的必需元素，且已被證實可以抑制蟲害，然而其效果受到餵食之食物來源所影響。本研究以蚯蚓餵食甘藍或豬糞以生產富含硫或養分之蚓糞堆肥，利用盆栽試驗及餵食試驗以評估施用上述蚓糞堆肥對於提升土壤肥力、促進小白菜生長及抑制斜紋夜蛾幼蟲生長之效果。研究結果顯示，食物來源會影響蚓糞堆肥之性質，餵食甘藍較餵食豬糞所生產出的蚓糞堆肥具有較高之硫含量，土壤施用蚓糞堆肥可以增加其有機質、有效性磷及交換性鉀、鈣、鎂之含量，小白菜的生長與累積的磷及硫濃度也會因施用蚓糞堆肥而增加。或許是葉片中的硫濃度因施用含硫肥料或是餵食甘藍所生產之蚓糞堆肥而增加之緣故，這些處理下斜紋夜蛾幼蟲的相對生長速率、總消耗量、消耗食物轉換率及相對消耗速率皆有所下降。 |
| 英文摘要 | (1) Background: Vermicompost is enriched in plant essential nutrients and has been shown to suppress the incidence of pests; however, its potential is affected by its food sources. (2) Methods: Earthworms were fed cabbage or pig manure to produce two vermicomposts enriched in sulfur and nutrients, respectively. A pot experiment and a feeding experiment were then conducted to determine whether the application of the vermicomposts and sulfur could increase soil fertility, promote the growth of Brassica chinensis L., and inhibit the growth of Spodoptera litura Fabricius larvae. (3) Results: The characteristics of the vermicomposts were mainly affected by the food sources, and vermicomposted cabbage was found to have a higher sulfur content than vermicomposted pig manure. The application of the vermicomposts enhanced the concentrations of organic matter and available phosphorus, as well as the exchange concentrations of potassium, cadmium, and magnesium in the soil. Moreover, the growth of and the accumulated phosphorus and sulfur in the B. chinensis L. samples significantly increased when the plants were grown in soil treated with the two vermicomposts. Hence, addition of vermicomposted cabbage and sulfur fertilizers can decrease the relative growth rate, total consumption, efficiency of conversion of ingested food, and relative consumption rate of S. litura larvae, possibly due to the increase in leaf sulfur concentration. |
| 發表成果與本中心研究主題相關性 | 以農業廢棄物餵食蚯蚓可以製成蚓糞堆肥，而將蚓糞堆肥施用於土壤則可以提升土壤品質及促進作物之生長表現。本研究則再將堆肥之抗蟲效果納入評估，試驗結果也顯示食用部分蚓糞堆肥所種植出之小白菜，確實會抑制斜紋夜蛾幼蟲之生長表現。農業廢棄物再利用為永續農業之操作方法之一，本研究之內容亦與中心之研究主題相符。 |
