摘要

本試驗的目的在探討黃豆粕、菜籽粕、雞糞堆肥及米糠堆肥等四種有機肥對有機米產量及品質之影響。各種有機肥之用量，換算成氮肥量為每公頃160公斤。試驗結果：二期作三年（87, 88, 89）平均稻穀公頃產量分別為4158公斤，4110公斤，3995公斤及4008公斤，但各處理區之間未達顯著差異水準，一期作二年（88, 89）平均稻穀公頃產量分別為6241公斤，6306公斤，6310公斤及5867公斤，米糠堆肥區一期作產量較其他各區低且達顯著水準，其餘各處理各年期的公頃產量之間未達顯著差異水準。各處理每公頃的有機肥價錢以雞糞堆肥處理區的58,560元最高，其次為米糠堆肥區52,560元，黃豆粕區19,995元，菜籽粕區18,240元最便宜。各年期施用各種有機肥之白米口味，經試吃結果，以黃豆粕區及菜籽粕區的被認為較佳。綜合產量、米質、食味之表現及資材之價格，菜籽粕及黃豆粕為本區水稻有機栽培較佳之肥培資材。

The purpose of this experiment was to investigate the effects of four different organic materials on the yield and quality of organic cultured rice. Soybean cake, rapeseed cake, chicken dropping compost and rice bran compost were used. The total nitrogen of each organic material applied was 160 kg/ha. In the 2nd rice crop, the yields (average of 1998, 1999 and 2000) of the four different treatments were 4158, 4110, 3995 and 4008 kg/ha, respectively. But there were no significantly different among those treatments. In the 1st rice crop, the yields (average of 1999 and 2000) of the four treatments were 6241, 6306, 6310 and 5867 kg/ha, respectively. The yield of rice bran compost treatment was lower than that the other three treatments significantly. The costs of four compost treatments were 19,995, 18,240, 58,560 and 52,560 NT/ha, respectively. The milled rice of each treatment was tasted by a group of person. They confirmed that the taste of rice treated by applied soybean cake and rapeseed cake were better than the others. From the above results, soybean cake and rapeseed cake were considered the better organic materials for produced organic cultured rice in Tainan district.
