應用微生物製劑提升洋桔梗生產及切花品質之研究

本試驗探討澆灌3種微生物製劑對促進洋桔梗生長及切花品質之影響。澆灌貝萊斯芽孢桿菌Tcb43及木黴菌TCT168製劑可提高洋桔梗株高及地上部鮮重，田間開3-7朵花之開花率以施用地衣芽孢桿菌TCLigB製劑之65%及木黴菌TCT168製劑之95%為最佳，顯著高於對照組0%。第8天切花瓶插性狀之分析結果，顯示未除蕾處理組以菌株Tcb43製劑具較佳之開花率，且花苞萎凋率顯著低於對照組，除蕾處理組則以菌株TCT168及TCLigB製劑之開花率與鮮重顯著高於對照處理組，葉片失水率則顯著低於對照組。第15天切花瓶插結果顯示未除蕾處理組之菌株TCT168製劑之開花率與鮮重顯著高於對照組，而花苞萎凋率則顯著低於對照組，除蕾處理組則以菌株TCT168與TCLigB製劑處理組之開花率與鮮重顯著高於對照組，葉片失水率顯著低於對照組，而花苞垂頸率則以TCT168製劑處理組最低。施用木黴菌可顯著提高多種元素含量，其中磷、銅及鋅含量於葉、莖及花中皆顯著提升，試驗結果顯示施用木黴菌TCT168製劑具最佳提升洋桔梗切花品質之效果。

In the experiment, three different microbial products were applied in Eustoma planted in the soil field for understanding their effects in increasing productivity and quality of cut flower. Drench of microbial products of Trichoderma sp. TCT168 and Bacillus velezensis Tcb43 can increase plant height and aboveground fresh weight. Higher flower open rate of Eustoma among 3-7 flower open in the field was found in the treatments with drench of microbial products of Trichoderma sp. TCT168 as 95% followed by 65% of Bacillus licheniformis TCLigB and 0% of CK treatment without application of microbial products. The characteristics of cut flowers in vase among different treatments were determined. At the 8^(th) day, in treatments without disbub, the flowering rate was higher but flower withering rate was lower in the treatment of applying microbial products of strain Tcb43 compared with no microbial application; in disbub treatments, flowering rate and aboveground fresh weight were higher but dehydration rate of leaf was lower found in the treatment of applying microbial products of strain TCT168 and TCLigB compared with no microbial application. At the 15^(th) day, in treatments without disbub, flowering rate and aboveground fresh weight were higher but flower withering rate was lower in the treatment of applying microbial products of strain TCT168 compared with no microbial application. In disbub treatments, flowering rate and aboveground fresh weight were higher but dehydration rate of leaf was lower found in the treatment of applying microbial products of strain TCT168 and TCLigB compared with no microbial application. Lower lodging rate was also found in the treatment of applying microbial products of strain TCT168. Compared with CK, applying microbial products of strain TCT168 can increase concentration of many elemental nutrients in plant, especially the concentration of phosphorous, copper and zinc was all increased in the leaf, stem and flower. The experimental results showed application of strain TCT168 products with the best effect in promoting growth of Eustoma in the field and its cut flower quality in vase.
