蕎麥及食用玉米有機生產管理模式之建立

Abstract

為建構雜糧作物種子友善環境生產體系，本研究分別以蕎麥及食用玉米為材料，嘗試開發建立其有機栽培生產模式，並同時評估碳化稻殼在此模式中之應用潛力，其試驗結果如下：(1)蕎麥參試品種生育期短且無明顯病蟲害發生，加上具備益蟲棲地營造之生態功能性，為適合投入有機栽培生產之作物種類。(2) 在以有機質肥料為作物養分來源，並搭配苦楝油及蘇力菌進行病蟲害防治之栽培管理方式下，食用玉米參試品種確實具備有機生產可行性。(3) 炭化稻殼施用並未出現增進參試作物表現之效果，惟其背後原因仍有待後續探討釐清。 For the purpose of the establishment of the environmentally friendly seed production system for grain crops, the buckwheat and sweet corn are utilized to try to establish the organic production systems in this study. Meanwhile, the potential of the application of carbonized rice husk for the system is also evaluated. The results are as follows: (1) The buckwheat variety tested has a short life cycle, and there are no diseases or pests occurred seriously in its life cycle. In addition, it has the ecological function of creating beneficial insect habitats. Therefore, the buckwheat is a kind of crop that is suitable for organic farming. (2) By the cultivation method that organic fertilizers are used as nutrient sources and neem oils and Bacillus thuringiensis (B.t.) are utilized to control the diseases and pests, the organic production of the sweet corn varieties tested is indeed feasible. (3) There are no positive effects occurred on the crops tested after the application of carbonized rice husk in this study, but the underlying reasons still need to be explored and clarified.
