中文摘要 | 本試驗針對作物的需肥特性研發釋出速率不同的生物可分解控釋型肥料,其30℃初期溶出率介於2.2%~50%之間。水稻臺南11號田間試驗,2010年一期作,一般化肥、控釋型肥料與對照組3處理間,產量達極顯著差異,以控釋肥處理790 kg/0.1ha最高,是一般推薦化肥量處理653 kg/0.1ha的121%,而未施肥空白區最低249 kg/0.1ha。2011年一期作產量以1倍控釋肥處理940 kg/0.1ha最高,0.8倍控釋肥處理910 kg/0.1ha次之,一般推薦化肥量處理882 kg/0.1ha,未施肥空白區最低483 kg/0.1ha。試驗結果顯示,控釋型肥料確實能提高產量、降低施肥量、減少人力支出與施肥次數,具省時及節能減碳的效果。 |
英文摘要 | We have developed some biodegradable controlled-release fertilizers with different release time based on the characteristics of crops, which can be used for most crops, and their Initial dissolution rate is between 2.2% to 50%. The results of field test of Tainan No. 11 rice in the first crop 2010, showed that the yields of three fertilizer treatments was significant difference. The highest yield (790 kg/0.1ha) was found in the controlled-release fertilizer treatment, general recommended amount of fertilizer treatment was next (653 kg/0.1ha), and blank treatment is the lowest (249 kg/0.1ha). For the yield of the first crop in 2011, the treatment of 1 time controlled-release fertilizer had the highest yield (940 kg/0.1ha), followed by the treatment of 0.8 time controlled-release fertilizer was (910 kg/0.1ha), and general recommended amount of fertilizer was (882 kg/0.1ha), and blank treatment is the worst (483 kg/0.1ha). The results showed that controlled-release fertilizer do increase rice production, reduce the amount of fertilizer use, and fertilizer to reduce the requirement of labor, and had benefits in saving time and energy as well as carbon reduction. |
