北部地區飼料甘藷低投入省工栽培系統建立

Abstract

本試驗101 年至103 年於本桃園縣新屋鄉 (本場) 作業田進行，主要目的係探討北部地區飼料甘藷的低投入省工栽培技術。結果顯示，以桃園3 號品種耕犁2 次作畦配合塑膠軟管噴灌處理21.5 t ha-1 最高；灌溉方式以旋轉噴灌11.6 t ha-1 最高；耕犁方式則以耕犁2 次作畦甘藷產量13.9 t ha-1 最高；品種則以桃園3 號13.4 t ha-1 最高，造成試驗產量不佳原因，係因每年於9 月均遭遇颱風淹水所致。另整地作畦費用每公頃20,000 元，本試驗作畦較不作畦處理，甘藷產量高約3,000 公斤，甘藷每公斤10 元計，共計30,000 元，故整地費用並無法涵蓋其產量的損失。故本試驗暫推薦北部地區甘藷栽種以塑膠軟管噴灌配合耕犂2 次作畦為最佳方式。 The field trials operating at Taoyuan County Township, the main purpose is to conduct feed sweet potato provincial industrial cultivation of low-input technology the northern region. The results showthe plows secondary plot and plastic hose sprinkler 21.5 t ha-1 is the highest yield of Taoyuan No3. Theirrigation method was rotating sprinkler 11.6 t ha-1 the highest yield. The tillage method was plows secondary plot 13.9 t ha-1 the highestyield. Taoyuan No.313.4 t ha-1was the highest yield. This experiment yields low reasons was due in August and September typhoon flooding. Another ridging soil preparation costs NT20,000 per hectare. This test is less ridging treatment; high yield about 3,000 kg of sweet potato. The NT 10 per kg, totaling NT30,000. The cost of site preparation and cannot cover the loss of its production. The test temporarily recommended potato planted in plastic hose sprinkler with plows secondary ridging is the best way in northern Taiwan.
