| 中文摘要 | Trichoderma harzianum,係自醱酵豬糞(CSM)中所分離出的一種植物病原 菌的拮抗菌,它在添加糖漿的CSM中雖可生長旺盛,但生長速率並不會比未添加 者快速,在CSV中添加0.1,0.5,及1.0(w/W)的酵母粉、玉米粉、澱粉、和纖維素, 均無法顯著地 (P=0.05)促進T.harzianum的生長及繁殖;在CSV中添加高嶺土、蒙特 石、滑石粉或矽化鈣也不會明顯地比不添加者能有效地提昇T.harzianum的存活 率;CSM中含有T.harzianum,並不會降低CSM中原存之細菌及真菌數量,但會增加 放射線菌的族群:利用含有T.harziannum,而無其他任何添加物之CSM栽培介質, 培育百日草及金盞菊的幼苗,此等幼苗移植後,可以顯著 (P=0.05)有效地抵抗存 在土中之立估絲核菌的感染;在移植後的士壤中,再添加T.harzianum,則防治效果 比育苗介質中僅有T.harzianum或栽植土壤中僅有T.harzianum者均佳。 |
| 英文摘要 | Trichoderma harzianum (Th) isolated from composted swinemanure (CSM) was an antagonist to plant pathogens. Although Thgrew and sporulated profusely in CSM amended with syrup, itsgrowth rate was the same as in CSM without amendment. CSM added with 0.1 , 0.5 or 1.0(W/W) yeast, corn powder, starch, orcellulose was not able to increase the growth and reproduction rateof Th. Kaolin, bentonite, talc, or calcium silicate failed to increasethe survival rate of Th in CSM. Th did not decrease the populationdensity of bacteria and fungi in CSM, but increased the population ofactinomycetes. Applying Th-containing CSM as bedding substratumto grow calendula and zinnia was able to make them resistant to theinfection caused by Rhizoctonia solani. The effect of controlling R.solani was greater when canlendula was cultivated fromTh-containing CSM and grown from Th-containg soil than this plantwas either only cultivated from Th-containing CSM or only grownfrom Th-containing soil. |
