中文摘要 | 甘藷為北部地區重要的雜糧作物,但冬季低溫易造成春作栽培種苗供應不足,而影響產業發展。本試驗以桃園3號、臺農57號及臺農66號品種為材料,評估不織布浮動式覆蓋應用於冬季甘藷種苗生產之可能性,以解決春作栽培所需種苗不足問題。在冬季低溫環境下以基重50 g m^(-2)不織布覆蓋處理,結果顯示土壤表面及土壤下方5cm處日平均溫度、日平均高溫、日平均低溫,分別較無覆蓋之對照提高1.2、0.6、3.5及1.8、0.6、4.6℃;且桃園3號、臺農57號及臺農66號每公頃先端苗產量分別為190,000、196,667及73,333 vine ha^(-1),較對照增加2.5、2.9及2.0倍。由本試驗結果可知,在北部地區冬季低溫環境,以基重50 g m^(-2)不織布浮動覆蓋,可以促進地上部生長,提高藷蔓先端苗產量。 |
英文摘要 | Sweet potato is an important upland crop in northern Taiwan. Insufficient supply of seedlings for spring cultivation due to low temperature in winter season, will result in problem affecting the development of industry. In this research we used sweet potato cultivars 'Taoyuan No.3','Tainung No.57'and'Tainung No.66'as materials to evaluate the possibility of floating cover with non-woven fabric on the seedlings production for solving the problem of insufficient supply of spring cultivation seedlings of sweet potato. Experimental results indicated that the mean temperature, mean maximum temperature and mean minimum temperature of a day at soil surface and soil temperature of 5cm depth under non-woven fabric (50 g m^(-2)) were 19.2℃, 28.3℃, 8.4℃ and 19.8℃, 27.9℃, 12.7℃ was 1.2℃, 0.6℃, 3.5 ℃ and 1.8℃, 0.6℃, 4.6℃ higher than that in the non-covered (control) in winter season. The seedlings yield of 'Taoyuan No.3', 'Tainung No.57' and'Tainung No.66' were 190,000 vine ha^(-1), 196,667 vine ha^(-1) and 73,333 vine ha^(-1) more than the non-covered (control) increasing about 2.5 times, 2.9 times and 2.0 times. The result showed that the growth of above ground and seedling yield of sweet potato were increased from floating cover with non-woven fabric (50 g m^(-2)) to overcome low temperature in winter season. |
