摘要

矽為水稻生長之必需元素，土壤有效矽因連作持續減少，補充矽肥為促進水稻生育方法之一；故本研究探討矽酸爐渣、矽藻土及炭化稻殼等三種矽酸資材施用後對土壤及水稻生育之影響。試驗結果顯示，以三種資材每公頃施用兩公噸後，各試區土壤酸鹼值介於6.6〜6.8，無顯著差異；土壤磷、鉀、鈣、鎂含量以施用矽酸爐渣及炭化稻殼之處理者略高於對照組，其中以炭化稻殼處理者最高。水稻插秧後60天調查葉片之SAPD值，各矽酸資材處理者之SAPD值均較對照組高；株高方面，矽酸資材處理與對照組間無顯著差異。在病害上，胡麻葉枯病的發生率以對照組最高，達18.8%，矽酸爐渣及炭化稻殼處理者較低，分別為8.3%及8.0%。乾穀產量在施用矽酸資材後可提高產量4.1%〜9.9%，以矽酸爐渣處理產量5855 kg/ha最高，炭化稻殼5750 kg/ha次之；稻米蛋白質含量以施用矽酸爐渣者較低，直鏈澱粉含量介於18.2〜18.3%，各處理間無明顯差異。

Silicon (Si) is essential nutrients of the rice growth. Cause soil silicon to reduce, because of continuous cropping. Add Silicon fertilizer can increase the growth of rice. In this paper, effect of silicon materials on rice growth and yield in paddy soil was studied. Some favorable effect of silicon materials was shown in these experiments because of plant analysis and soil testing. The results indicated soil pH is between 6.6-6.8. No significant differences. Determination of soil phosphorus, potassium, calcium, and magnesium content. Significantly higher than the control of silicate slag and carbonized husk. Highest in carbonized husk. Measured 60 days after transplanting leaves SAPD value. Silicate materials to deal with significantly higher. Brown spot disease of rice occurred up to 18.8%, without the use of silicate materials. The brown spot disease of rice was not obvious that the silicate slag and Carbonized husk of 8.3% and 8.0%. Rice production in the application of silicate materials can improve the yield of 4.1% to 9.9%. Silicate slag processing a maximum of 5855 kg/ha, Carbonized rice husk is 5750 kg/ha followed. Rice protein content and amylose content ranged from 6.4-6.1% and 18.3-18.3%. The form protein content and amylose content are not significantly different among treatments.
