臺灣養豬業很興盛,尤其是屏東,根據農委會109年11月份養豬頭數調查報告,屏東縣為全國第二大養豬重鎮,因此養豬廢水成為最大的河川污染源,破壞了生態環境。畜牧糞尿具有高濃度有機物質,也具有植物生長所需要的營養素氮、磷、鉀,可代替化學肥料的使用,推動友善農業;畜牧業大都以三段式處理廢水,故為降低對河川的污染,減少廢水處理成本及降低農田化學肥料的使用,本研究以畜牧廢水處理後的放流水澆灌於植栽為研究對象。在研究方法上,採用二法:(一)文獻分析法:多方蒐集與彙整有關文獻包括博碩士論文、網路資源、各種政府的計畫報告書等資料作為文獻參考的主要根據。(二)實驗法:本研究用花盆、泡沬箱種植作實驗並在自己的實驗場域現場觀察、探勘、拍照作成記錄分析資料。在種植蔬菜、花卉的過程中,會有病蟲害,根據農友的經驗只要日照時間足夠,一般病害比較少。本研究分為實驗組(放流水)、對照組(自來水),根據實驗觀察結果,放流水澆灌於植栽,不但植物生長速度快,植栽品質優於自來水澆灌的植物,而且還能防止蟲害。本研究對於學術研究之貢獻:本研究成果可提供沼液沼渣資源化再利用,解決台灣枯水期之缺水現象及畜牧業、農業、政府環保單位作為植栽澆灌的参考依據。
The pig industry in Taiwan is very prosperous, especially in Pingtung. According to the survey report of the number of pigs raised by the Council of Agriculture in November 109, Pingtung County is the second largest pig-raising town in the country, so pig-raising wastewater has become the largest source of river pollution and damage The ecological environment. Livestock manure has high concentration of organic matter, as well as the nutrients nitrogen, phosphorus, and potassium needed for plant growth, which can replace the use of chemical fertilizers and promote friendly agriculture; most of the livestock industry uses three-stage wastewater treatment, so it is to reduce river pollution , To reduce the cost of wastewater treatment and the use of chemical fertilizers in farmland. This study takes the discharged water from livestock wastewater treatment to irrigate plants and plants as the research object. In terms of research methods, two methods are used: (1) Literature analysis method: Multi-party collection and compilation of relevant literature, including doctoral and master's theses, Internet resources, various government project reports, etc., are used as the main basis for literature references. (2) Experimental method: This study uses flower pots and foam boxes for experiments, and observes, surveys, and takes photos in the own experimental field to make records and analysis data. In the process of planting vegetables and flowers, there will be pests and diseases. According to the experience of farmers, as long as the sunshine time is sufficient, there are generally fewer diseases. This study is divided into experimental group (draining water) and control group (tap water). According to experimental observations, irrigation with running water not only grows faster, the quality of plants is better than that of plants irrigated with tap water, but also prevents pests. . Contributions of this research to academic research: The results of this research can provide resources for the reuse of biogas slurry and residues, solve the water shortage phenomenon in Taiwan during the dry season, and use animal husbandry, agriculture, and government environmental protection agencies as a reference for planting and irrigation.
