• 中文摘要： 本研究以水稻臺農67號及臺南5號兩品種參試，期使明瞭水稻谷殼施用量每公頃20噸之肥效，其結果如下：1.臺農67號及臺南5號品種在水稻田谷殼施用下，比對照區的產量分別增產12%及6%。2.臺農67號及臺南5號品種施用谷殼後，均可增加葉片表皮組織葉脈間的矽化細胞數目。3.施用谷殼對兩參試品種之根系發育具促進效果，根系發達，在土層中分佈廣泛且較長。
• 英文摘要： Rice hulls was applied to loam alluvialsoil at the rate of 20 tons per hectare beforeplowing of the second crop rice. The varietiesstudied were japonica rice Tainung No. 67and Tainan 5. The result are summarized asfollows: 1. Yield increase were about 12% and6% for Tainung No. 67 and Tainan 5, respec-tively. 2. Number of silicified cells on the epi-dermal tissue of leaf blades in Tainung No. 67 and Tainan 5, was high remarkably inplots treated with rice hull than those non-treated. 3. The plots of rice hull treatmentalso showed a higher root development thanthose nontreated in both varieties.
