中文摘要 | 台中189號係由台農67號(母本)與台中187號(父本)雜交而育成之梗稻 品種,具有強稈、抗稻熱病、米質佳及產量安定等特性,於民國72年6月17 日獲准登記命名及推廣。本品種對葉及穗稻熱病抵抗性強,適合於第一期作稻熱 病容易發生地區栽培。由於其分蘗及穗數較少,故應行密植增肥或選擇地力肥沃 土壤栽培。台中189號雖然稻稈粗壯、強韌,不易倒伏,但因其株高比台農67 號高3∼5公分,故應注意栽培管理技術,為促使分蘗數增加,肥料宜早期施用 且於插秧後第一期作45天,第二期作30天應行斷肥,同時配合晒田作業以抑制 無效分蘗及防止植株徒長。本品種屬偏穗重型,應施用穗肥以增加一穗粒數及穗 重,藉以提高單位面積產量。本品不抗白葉枯病,在低窪,排水不良或風大容易 發生白葉枯病地區避免種植,對褐飛蝨亦無抵抗性,須按照植物保護手冊推薦之 方法予以防治。收穫前不可太早斷水,尤其天晴的大熱天,不要有缺水現象,以 免影響稻米品質。 |
英文摘要 | Taichung No. 189 is a Japonica variety of rice developed by crossing Tainung No. 67 (maternal parent) with Taichung No. 187 (paternal parent). With the characteristics of strong culm, blast resistance, good rice quality, and stability in grain yield, it was named and released to the farmers on June 17, 1983. Since the variety showed strong resistance to both leaf and panicle blast, it is suitable for being grown in the area where blast is ofter very serious in the first crop. Due to its slightly lower tillering ability and panicle number, it is better to grow the variety in the fertile soil or adopt the close spacing and intensive fertilization program for growing the variety. Although the variety has strong culm and is resistant to lodging, it is taller than Tainung No. 67 for about 3-5 cm, and therefore some precaution must be taken in the fertilization technique. In order to get higher tiller number, the fertilizers should be applied as early as possible but it should be ceased on the 45th day after transplanting for the first crop, and on the 30th day after transplanting for the second crop, accompanied by proper draining to inhibit the growth of ineffective tiller and the elongation of rice plants. However, as the variety belongs to the heavy spike type, proper amount of panicle fertilizer should be applied to help get higher grain number in a panicle to reach the goal of high grain yield. As the variety is not resistant to bacterial leaf blight, it is better not to grow in the poorly drained or windy area where bacterial leaf blight is ofter serious. The brown plant hopper is also necessary to be controlled according to the methods recommended in the plant protection handbook. The irrigation should not be cut off too early before the harvest, especially at hot season, as hot season, as to influence the rice quality. |
