Agronomic characters and nutrient absorption of rice plants, Taichung No. 65 under the following treatments were investigated using pot culture. Two temperature plots (different temperatures in two glass-house), two kinds of soils (Pingtung slate and Taipei sandstone and shale alluvial soils) and two different rates of compost (5) g per pot and no application of crude compost), thus total of eight treatments were examined in an experiment of factorial design.
The high temperatures promoted plant length and heading date and increased the yields in the second crop. The high temperature also increased K contents and decr-eased N contents of straw. Total amounts of K absorption were generally increased by high temperatures.
Kind of soil gave distinctly different characters on plant growth. Plant length was longer and tiller number was less in Pingtung soil than in Taipei soil. Plants grown in Pingtung soil had more absorption of K, Si, Mn and less of N, P and Fe than in Taipei soil. It seems that Taipei soil is deficient in available Si and Mn.
Effect of compost shown a significant interaction with soil on rice yield especially in the first crop. Application of crude compost shown detrimental effect to the yield in Pingtung soil while Taipei soil was beneifited by it. It is considered that some specific characters of these two soil caused different deconiposition process of compost which in turn effect on crop yields.
以水稻臺中65號舉行玻璃室盆栽試驗，比較在屏東粘板岩沖積上及臺北砂岩頁岩沖積土，施用與不施堆肥，並在不同溫度處理下之水稻生育性狀和養分吸收。試驗仍如前報，於兩玻璃室內進行，其一係玻璃窗開啟，另一則關閉以做為比較上之高低溫區。如此水稻生育期間，高溫區平均溫度高於低溫度約 2.1oC~2.5oC。所施用之堆肥為碳氮比率 20 之半熟稻藥堆肥，其結果如下：
