中文摘要 | 本試驗旨在探討綠竹炭施用量對設施栽培萵苣生育及產量之效應。試驗採逢機完全區集設計,綠竹炭施用量為1,000、1,500、2,000 kg ha-1及不施用為對照組等4種處理。綠竹炭材質分析結果pH值 10.0、EC值1.02 dS m-1為強鹼性資材。結果顯示,以施用1,000 kg ha-1綠竹炭處理的時,600 kg ha-1產量最佳,較未施用的對照處理增產11%,處理問差異達顯著水準;但施用量增加至2,000 kg ha-1時, 產量會有顯著減少的趨勢,甚至較對照處理減產6%。另土壤分析結果,施用綠竹炭可提升土壤pH值、降低EC值,於弱酸性土壤栽培萵苣時,適量施用綠竹炭有促進植株生育及增產的效果,但施用過量會對產量有不利之影響。 |
英文摘要 | The experiment was conducted to study the effects of application of green bamboo charcoal on the growth and yield of lettuce (Lactuca sativa L.) in plastic house. A randomized complete block design was used, and the treatments included the applications of 1,000, 1,500, and 2,000 kg ha-1 of green bamboo charcoal. The green bamboo charcoal is a strong basic material with pH 10 and 1.02 dS m-1 of EC value. The results showed that the yields of lettuce culturing in weakly acid soil were the highest by applying 1,000 kg ha-1 of green bamboo charcoal which was about 11 % significantly more than without applying green bamboo charcoal treatment, but it was decreased 6 % significantly by applying 2,000 kg ha.1 than without applying green bamboo charcoal treatment. Results indicated that it could increase the soil pH values, decrease the EC values, promote the growth, and raise the yield of lettuce, if proper amounts of green bamboo charcoal were applied. |
