高產飼料稻米專用品種之選育

Abstract

近年全球氣候異常，重大災變以不尋常頻率接連發生，致使地區性的糧食生產呈現不穩，對於糧食自給率偏低的我國，必須要有戰備存糧的戰略思考；在因應加入世界貿易組織（WTO）開放稻米市場下，國內休耕大量的稻田，這些長期沒有耕作的土地，地力不但沒有獲得養息，反而是病蟲及媒介越冬的溫床，對整個農業生態平衡及生產造成影響；日韓及中國等國為因應自身的飼料原料需求，都研發飼料用稻的品種。臺灣有栽種水稻的得天獨厚地理環境，悠久且有系統的稻作研究基礎，開發適合國情的飼料用稻米品種，讓飼料原料來源多元化，除了可以作為活化休耕田的策略選擇，亦可增加水田面積，降低熱島效應及防止洪害、減少徑流，發揮水田涵養地下水的重要生態意義，對於提高糧食自給率亦能發揮正面效益。 In recent years, global climate anomalies, an unusual frequency of major catastrophe occurred, resulting in regional food production showed instability, low rate of food self-sufficiency for our country, we must have food stocks readiness of strategic thinking; in response to the World Trade Organization (WTO ) open the rice market, the domestic large number of fallow paddy fields, these long-term there is no farming land, fertility not only did not get raised interest rates, but is a hotbed of wintering pests and media, have an impact on the ecological balance and overall agricultural production; Japan and South Korea and China other countries in response to their demand for raw materials to feed, all varieties of rice developed feed. Taiwan has a unique geographical environment planted rice, long and systematic basis for rice research and development conditions for the feed rice varieties, so to diversify sources of feed ingredients, in addition to the activation of fallow fields as a strategic choice, but also increase the paddy field area, reduce the heat island effect and prevent flood damage, reduce runoff, groundwater conservation of paddy fields play an important ecological significance for improving food self-sufficiency can also play a positive benefit.
