Abstract

農業廢棄物蘊含有豐富的微生物與有機成分。將它們妥善的堆肥化處理，不但可降低環境污染的衝擊外，尚可研製優良的有機堆肥與栽培介質，創造農業資源的永續利用。筆者研究發現香菇太空包廢棄物堆肥具有顯著抑制西瓜蔓割病菌(Fusarium oxysporum f. sp. niveum)，甘藍苗根瘤病菌 (Plasmodiophora brassicae)，番茄根腐病菌(Pythium myriotylum)及番茄根瘤線蟲 (Meloidogyne incognita)等引起的病害；此外，金針菇生長過的基質所製成的堆肥尚可保護豌豆根系免於拉草與丁基拉草的毒傷。利用農業廢棄物的抑菌特性與其豐富的微生物資源，筆者已成功研製SSC-06、FBN-5A及THC-23 等種抑菌介質與有機添加物；它們均具有促進農作物生育與減少病害發生的效果。綜合一系列的研究證實抑病介質與有機添加物的防病原理，主要與其組成資材的化學成分及其原棲居或新導入之微生物間存在有密切的相關性。 Agricultural wastes such as rice straw, rice hull, peanut husk, corn cob, bagasse, rape-seed pomace, castor seed pomace, tree bark, mushroom growth medium waste and shrimp shell powder are widely used in land reclamation and in production of horticultural crops. They benefit crop production by improving soil fertility, increasing soil fertility, increasing soil organic matter and, in many instances, reducing the incidence of soilborne diseases. Several container media and organic amendments, e.g. SSC-06, FBN-5A, and THC-23 mixtures have been formulated by using agricultural wastes and fertilizers for the management of crop diseases in Taiwan. Most of the formulated products were designed to maximize the harmful effect on target pathogens and maintain soil fertility with minimal negative impacts on the agroecosystem. The mechanisms by which container media and soil amendments affect plant pathogens can be simple or complex depending on the pathogen. In some cases, control is achieved by direct killing of the pathogen propagules, in other cases, disease suppression is the result of a combination of multiple factors, including direct poisoning of the pathogen and indirect effects by enhanced microbial activity and improved vigor of plants.
