中文摘要 | 本研究在尋求適當之除草劑種類及使用量,以有效的控制高山林地習見之雜草如箭竹及萱草類,並配合割草機之使用及人工除草,以比較不同除草方法,對於雜草之生態的及經濟的影響。 試驗係於民國61年至62年間在大雪山林業公司第一林務站,選擇以分佈箭竹及萱草為主之林地各一處實施。除草劑之種類選用氯酸鈉(Sodium chlorate), Frenock (2, 2, 3, 3-Tetraflaropropionic acid, sodium) 之單用,及Basfapon (2, 2-Dichloropropionic acid, sodium salt)與2, 4, 5-T之混用。除草劑之使用量分為高低兩種,並分為於人工、割草機刈除雜草後不施除草直接噴射除草劑。 各處理對於雜草之控制,以在噴射除草劑前先行除草(手刈及機刈)之效果為佳,不施刈草而直接噴射除草劑者效果未著。 Frenock初期控制雜草之效果不如氯酸鈉及Basfapon,惟後期之雜草控制並未較其餘兩種為差。在一年間雜草之發生量,不同除草劑及使用量之差異均未達顯著水準。 各種雜草劑之高用量已顯著的降低臺灣二葉松幼苗之成活率。使用割草機刈除組織強韌之箭竹及萱草,概可較人工除草節省三分之二之工作時間。故本試驗建議對於箭竹及萱草之控制,應先使用刈草機刈除後,再噴射上記任何一種除草劑之低用量。 |
英文摘要 | The objective of this study was to find out the dosages and kinds of herbicide which could effectively control the weeds of arrow bamboo (Pleioblastus niitakayamensis) and miscanthus (Miscanthus trnasmorrisonensis) distributed on the higher mountain land. Hand and mechanical weeding were used prior to the application of herbicide. The ecological and economical difference between weeding methods were compared under different treatment in addition to weed control purpose. In this study there were three treatments containing frenock (2, 2, 3, 3-Tetrafluoropropionic acid, sodium) Na ClO3 (Sodium chlorate) used as single application and basfapon (2, 2-Dichloropionic acid, sodium salt) and U-46 brush killer (2, 4, 5-T) were used as combined application. Each treatment contained high and low dosages. The application of herbicide was followed a weeding by hand tool or brush cutter or applied directly to the weeds without weeding. The study was conducted from 1972 to 1973 in the Anmashan forest district of Tashueshan Forest Corporation located ain Central Taiwan. Weed control result of herbicide was significant when weeds were mowed either by hand or machine before applicaiton of herbicide. The effectiveness of weed control of frencok was little slow as compared with Na ClO3 and basfapon +2, 4, 5-T. In one study year, there was no significant difference of weed production on the kinds and dosages of herbicides except the weeding methods prior to the application of herbicide which greatly affected the effectiveness of herbicidal treatment. Only the high dosages of each treatment was greatly affected the survival of seedlings of Pinus taiwanensis planted two months after herbicidal application. Bacause the plant tissue of arrow bamboo and miscanthus were very hard and strong, machine cut saved two third of labour man hour as compared to the hand weedings. It is recommended to the control of high mountain arrow bamboo and miscanthus, the best treatment is to mow the weeds first with brush cutter then apply any of the herbicide used in this study but with low dosages. |
