Abstract
本試驗目的主要在探討不織布浮動式覆蓋應用於北部地區冬季甘藷種苗生產之影響。試驗結果顯示，在冬季低溫環境下以基重50g m-2 不織布覆蓋處理，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、分別為19.2℃、28.3℃、8.4℃及19.8℃、27.9℃、12.7℃，分別較無覆蓋之對照提高1.2℃、0.6℃、3.5℃及1.8℃、0.6℃及4.6℃，且有較高的存活率和地上部生長勢而顯著提高甘藷種苗產量。
This research was conducted to evaluate the effects of floating cover with non-woven fabric on the seedlings production of sweet potato in winter season in northern Taiwan. The result shows than highest survival rate and growth of above ground resulted in significantly increase of seedling yield of sweet potato from floating cover with non-woven fabric (50g m-2). The mean temperature, mean maximum temperature and mean minimum temperature of day of soil surface and soil temperature of 5cm depth under non-woven fabric (50g 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.
