台東區農業改良場推廣稻草再利用 抑制雜草減少塑膠廢棄物

Quick Look

台東區農業改良場推廣稻草再利用技術,透過沼渣沼液施用加速稻草分解為有機質養分,減少化學肥料依賴並提升產量;另利用稻草編織機製成草蓆鋪設田間,有效抑制雜草生長、減少除草劑使用,取代難以回收的銀黑塑膠布,從源頭降低塑膠廢棄物,解決稻草處理難題。

Why It Matters

稻草傳統處理方式包括露天焚燒造成空氣污染與公安疑慮,或直接翻耕入土易引發發酵害病影響下一期作發育,長期被視為農業廢棄物難題。

台東區農業改良場推廣稻草再利用技術,透過搭配沼渣沼液的施用,能有效加速稻草在田間分解並回歸土壤,迅速轉化為有機質與養分,除了減少化學肥料依賴與施肥工資外,更經實證能提升產量且不影響米質。另一方面,利用稻草編織機將其製成草蓆鋪設於田間,更能作為優良的雜草管理資材,不僅能有效抑制雜草生長、減少除草劑使用,更能直接取代傳統田間難以回收的銀黑塑膠布,從源頭減少塑膠廢棄物。

每逢水稻收穫季節,田間傳統上常面臨稻草處理的兩難。過去許多農友為了省時省力,多半選擇將稻草就地露天焚燒,不僅容易造成嚴重的空氣污染與公安疑慮,甚至可能遭受法規裁罰;即使選擇直接翻耕入土,若缺乏適當的分解機制,稻草在土壤中腐熟過程中產生的氣體與熱能,也容易引發水稻發酵害病、影響下一期作的發育。這些數量龐大的農業剩餘資材,長年以來一直被視為棘手的農業廢棄物。

請繼續往下閱讀...

如今隨著循環農業技術的突破,稻草正全方位擺脫過去的困境,轉化為友善環境的寶貴資源。台東區農業改良場推廣施用沼渣沼液,或將稻草回收作為雜草管理資材,可減少化學肥料及除草劑的使用,未來規劃與業者合作建立稻草暫存堆置場域,進一步研發有機質肥料與栽培介質。將昔日令人頭痛的稻草轉化為高價值的農業循環資源,不僅為農民節減栽培成本,也為永續農業開創了全新的綠色契機。

Scientifically prevent and control autumn grain crop diseases and insect pests to regain the food eaten by insects

The area where autumn grain diseases and insect pests occur nationwide is 1.15 billion acres, a year-on-year increase of 4%. Rice planthoppers are more frequent in the middle and late rice areas of Jiangnan and the middle and lower reaches of the Yangtze River than in previous years. Experts recommend adopting a comprehensive prevention and control strategy that combines physical and chemical induction and control, biological control and scientific and safe pesticide use, focusing on the prevention and control of rice planthoppers, stem borers and other pests to achieve the goal of "pests taking over food".
