中文摘要 | 蝶蘭是台灣重要之花卉產業, 2004 年種植面積約有 100 公頃,約佔蘭花總產業之 21% ,在外銷上具有重要的地位,同年出口產值約 8 億元 (8) 。近年來中南部積極發展此項產業,預估蝴蝶蘭產業仍會持續成長 (3) 。 蝴蝶蘭之生長分為 營養 生長期與調花期, 營養 生長週期 對溫度、光照、養分需求非常敏感,最適生長溫度為 25 ~ 30°C , 主要促進蘭苗葉片生長,日夜溫差之調控,也影響未來 花梗之形成。 而花梗抽出後進入 調花 生長週期,最適生長溫度範圍為 20 ~ 25°C , 可促使花苞開花 。 目前為 符合品質要 求,生產設施已由氣密式負壓風扇水牆與冷房之環控溫室取代 (2) 。近年來農民陸續反應溫室內常發生 落蕾(俗稱掉苞)之現象,發生時期以春季至夏季期間居多。經初步發現, 落蕾現象與蟎類或細菌感染有關,因此擬進一步 探討 蟎類及病原細菌造成蝴蝶蘭生物性落蕾之原因,及其發生之環境條件。 |
英文摘要 | Common ragweed ( Ambrosia artemisiifolia ) is one of the principal causes of late-season "hay fever" allergies. It is regarded as one of the worst weeds in many countries because its invasiveness, potential for spread, and economic and environmental impacts. In this study, the effects of temperature, pH, water potential and planting depth on the growth common ragweed were determined. Temperatures suitable for seed germination of common ragweed ranged from 8 to 36 °C. Initial germination was around 4 days after treatment in range of 20-32℃, and accumulated germination reached a plateau at 60-68 % from 12-16℃ about 50 days after planting. Light was not required for seed germination; both 50 % and 65 % of germination rate were obtained in light and in the dark, respectively. Seedling emergence decreased with the increased planting depth, and the maximum limit of depth for emergence was 5 cm. In addition, 64-72 % of seed germination was found at pH value between 6 to 9. Under the water potential below -0.4 MPa, seed germination decreased significantly with water stress. We tested normal field used rate (X) and reduced rate (0.75X) of 22 herbicides on common ragweed. Pre-emergence test showed that atrazine, diuron, and metribuzin provided 99 % of control percentage, and the same control was found in 0.75X treatment. Post-emergence application of glufosinate, glyphosate, paraquat and metribuzin resulted in 92-100 % reduction in fresh weight at 21 days after foliar application. Flazasulfuron and bentazon provided 66-73 % control, and these herbicides at reduced rates were less effective. |
