Abstract

本試驗探討良質米生產的土壤管理模式，由台灣中部地區自1989年至1991年間，調查90處稻田所得之17個土壤物理、化學、及肥力因子，對13項稻米品質進行之逐步迴歸分析。结果顯示，對米飯食味總評之土壞管理模式為y = -0.0357 + 3.03 x 10：(有機質x鋅)- 3.16 x 10 5 (氮 x 鋅) + 6.00 x 10 s (鈣 x 鐵) -9.56 x 10 5 (鎂 x 鋅)+ 1.62 x 105 (鐵 x Eh 下降速率) (R2= 0.7859)，對米飯均衡度之土壤管理模式則為y = ().丨044+ 5.52 x 10 3 (有機質)-1.03 x 10 4 (鎂)-5.80 x 10 5 (Eh) + 4.00 x 10 8 (鎂)2- 7.86 x 10 s (鋅)2 (R2 = 0.6619)，對白米粗蛋白含量之土壤管理模式為y = 6.7077 x0.265 (有機質)+0.223 (鋅)- 0.0Q59 (鋅)2+ 1.00 x 10H (鈣) (R2 = 0.6637)，其他對白米直5連澱粉含量，有關各項碾米品質，米飯質地，及米飯各食味品評項目，包括米飯外觀、香氣、口味、黏性及硬性，均分別得到有意義（決定係數顯著）之土壤管理模式。由土壤管理模式综合结果顯示透過合理的土壤管理，諸如增加土壤有機質，適度減少亂肥施用，提昇土壤氣化還原電位，並適度增加土壤中鉀、鐵和鋅的含量，均有助於提昇米質。 This experiment aimed on the modeling of soil management for production of good quality rice. Stepwise regression analyses were made for 17 soil physical, chemical and fertility properties on 13 items of rice qualities collected from 90 locations of paddy fields at central Taiwan from 1989 to 1991. The model for over all eating quality of cooked rice is y = -0.0 357 + 3.03x10 2 (OM x Zn) - 3.16 x 10 5 (N x Zn) + 6.00 x 10 8 (Ca x Fe) -9.56 x 10 5 (Mg x Zn) + 1.62 x 10 5 (Fe x Ehs) (R: = 0.7859). The model for balance of cooked rice is y = 0.1044 + 5.52 x 10 3 (OM) -1.03 x 104 (Mg) - 5.80 x 10 5 (Eh) + 4.00 x 10 x (Mg)2 - 7.86 x 10'5 (Zn)2 (R2 = 0.6619). The soil management model for the protein content is y = 6.7077 - 0.265 (OM) + 0.223(Zn) - 0.0059 (Zn)2 + 1.00 x 10 H (Ca) (R:= 0.6637). The model of soil management for amylose content, milling qualities, cooked rice texture, sensory evaluation of cooked rice including appearance, aroma, flavor, cohesion and hardness are also obtained. Through these models, it is suggested that application of organic matter, adequately reducing nitrogen fertilizer, promotion of redox potential and availability of soil potassium, iron and zinc, are essential for the production of better quality rice.
