摘要

本研究之目的爲比較亞麻立枯病（萎凋病）抑病土壤和導病土壤內細菌之分佈情形，並報導利用分離自抑病土壤之嫌氣性芽抱桿菌防治亞麻立枯病之盆栽試驗結果。導病土壤內以球菌和放射菌數量較多，而抑病土壤內則以革蘭陰性桿菌及嫌氣性芽孢桿菌居多。
從抑病土壤分離之嫌氣性芽孢桿菌能抑制爲害亞麻、豌豆、西瓜、番茄及香蕉（Race 1及T）等之萎凋病鐮刀菌菌絲之生長。盆栽試驗結果發現如接種此等細菌至病土內，並保持土壤酸鹼度爲中性及維持適當土壤水份，能有效防治亞麻立枯病之發生。

並列摘要

Bacteria were examined in two soils similar except that one was conducive while the other one suppressive to flax Fusariumwilt. Bacterial flora differed markedly between these two soils. The former had a higher count of cocci and actinomycetes whereas the latter had a higher count of anaerobic bacteria and gram-negative rods. Several Clostridiem spp. isolated from the suppressive soil were inhibitory to various formae of F. oxysporum including lini, pisi, niveum, lycopersici, and cubense race 1 and race T. In the pot test Fusarium-wilt was controlled by inoculating Clostridium sp. into moist soil kept at a neutral pH condition.
