Abstract

調查分析臺灣中部地區108個地點土壤及米質資料，利用米質優劣之差異進行各項土壤肥力因子對比。對比結果顯示，不論在總評、外觀、香味、口味、粘性、硬性等影響米飯食味品質因素中，土壤交換性鎂、鋅皆達極顯著差異，顯示土壤交換性鎂、鋅含量較低，生產之米飯食味均有較佳之趨勢。土壤全氮含量較低者，各項米飯食味皆顯著改善。另以米飯物性均衡度之優劣對土壤肥力因子進行對比，顯示全氮、交換性鎂、鈣、锌含量較低之土壤，生產之米飯均衡度有較佳之趨勢。有機質含量較高之土壤，有助於生產均衡度較優之稻米。從土壤肥力管理觀點，減少氮肥施用，選择交換性鐵、鈣、辞含量較低土壤，並選擇施用高碳氮比的有機肥，可能有助於生產較高品質的良質米。 Field experiments including 108 paddy fields at central Taiwan were conducted to investigate the effect of soil fertility on rice eating quality. Data of the soil and the rice quality were analyzed, the differences of the soil properties between the two classes of rice quality, the better and the poorer one，were tested by linear contrast. It was showed that rice eating quality in appearance, aroma, flavor, clavor, cohesion, hardness and overall sensory evaluation, are significantly affected by contents of exchangeable magnesium and zinc in soils. A lower soil exchangeable magnesium and zinc contents enhanced the eating quality of rice. Soils with lower total nitrogen contents also produced rice with high eating quality. Rice with the best balance (-H/H) by physical test were produced from soils with a lower nitrogen, exchangeable magnesium, calcium and zinc contents. Soils with higher organic matter also produced rice with higher balance. The results suggest that decreasing nitrogen fertilizer input，selecting soils with lower exchangeable magnesium, calcium and zinc contents, and applying organic matter with a higher carbon nitrogen ratio (C/N) are essential to high quality vice production.
