摘要

以臺東地區種植的水稻品種，調查土壤、水質、氣象條件及栽培方式等項目，探討良質米生產的優越環境，強化本區水稻之生產。試驗結果顯示，臺東、關山及池上的灌溉水質良好，SAR值在3.098－3.415之間，屬於C2-S1分類。土壤有機質、有效性磷、鉀及鈣等的含量在試驗後均呈現增加的現象，鎂則有減少的趨勢。93年一期作4個供試品種，以有機質肥料替代第一次追肥處理發現，以臺稉2號表現較佳，產量為7,040kg/ha。採用慣行法之處理以臺東30號的產量較高，約6,435kg/ha。93年二期作4個供試品種產量的表現沒有明顯差異，不同肥料管理之處理均以臺稉9號的產量較高，為6,233kg/ha左右。94年一、二期作，若以有機質肥料替代第一次追肥之處理，都以臺東30號表現較佳，各為6,270kg/ha及7,810kg/ha。採用慣行法之處理則以臺稉2號的產量較高，約8,800kg/ha及5,995kg/ha。代表米質好壞的味度值，兩年四期作均以臺東30號較佳，各品種味度值的表現第二期作較第一期作好。

Investigation on the paddy soil, water quality, meteorological condition and cultural management of rice varieties at Taitung area, to strengthen the production of yield and quality. Results indicated that the irrigation water of Taitung, Guanshan and Chishang showed good quality, the value of SAR between 3.098-3.415, belongs to the C2-S1 classification. Organic matter content, efficient phosphorous, potassium, calcium contents of soil showed increased tendency, but magnesium content had reduced after experiment. The yield of F1 treatment on 1st crop of 2004 showed Taikeng 2 had highest yield among others, about 7,040kg/ha, F2 treatment on 2nd crop of 2004, had no significant among all the varieties. But the Fl treatment on 1st crop and 2nd crop of 2005 showed Taitung 30 had highest yield among others, about 6,270kg/ha and 7,810kg/ha, respectively. Otherwise, the F2 treatment on 1st crop and 2nd crop of 2005 showed Taikeng 2 had highest yield, about 8,800kg/ha and 5,995kg/ha, respectively. The test of value on four crops of the experiment indicated that Taitung 30 had the best good quality.
