有機追肥施用時期對水稻產量之影響
作者:李健捀、陳榮五、蔡宜峰
摘  要

   本試驗自 2003 年一期作開始,至 2004 年二期作止。在臺中區農業改良場試驗田進行田間試驗。探討有機追肥施用時期對於水稻產量之影響。試驗為避免因病蟲之危害,而影響肥料之實質表現,因此於水稻生育全程均以化學藥劑控制病蟲害之發生。結果顯示一期作施用菜籽粕 4 ton/ha ,分三次施用,基肥 2 ton/ha ,移植後 30 天施用第一次追肥 1 ton/ha ,移植後 50~60 天施用第二次追肥 1 ton/ha ,其產量表現較高。二期作則以施用菜籽粕 4 ton/ha ,分三次施用,基肥 2 ton/ha ,移植後 20 天施用第一次追肥 1 ton/ha ,移植後 40 天施用第二次追肥 1 ton/ha ,其產量表現較高。兩期作均以基肥施用雞糞堆肥 12 ton/ha ,第一次追肥菜籽粕 1 ton/ha ( 一期作移植後 30 天,二期作移植後 20 天 ) ,第二次追肥菜籽粕 1 ton/ha ( 一期作移植後 50 天,二期作移植後 30 天 ) 之處理,其水稻產量表現最差。

ABSTRACT
   Field experiments were carried out during the first and second crops in 2003 and 2004 to investigate the effects of applied stage of organic top-dressing on the yield of three rice cultivars, i.e., Tainung 67 and Tai keng 9 of Japonica type, and Taichung sen 10 of Indica type. Six fertilizer treatments were conducted in this study. Under well control of blight on the first crop, the treatments including rape seed meal 2 tons/ha served as base fertilizers, rape seed meal 1 tons/ha served as first top-dressing applied on 30 days after transplanting, rape seed meal 1 tons/ha served as second top-dressing applied on 50 or 60 days after transplanting, that rice yields were higher than that of other fertilizers treatments. On the second crop, the treatment including rape seed meal 2 tons/ha served as base fertilizers, rape seed meal 1 tons/ha served as first top-dressing applied on 20 days after transplanting, rape seed meal 1 tons/ha served as second top-dressing applied on 40 days after transplanting, that rice yields were higher than that of other fertilizers treatments. On the first and second crops, the treatments including chicken composts 12 tons/ha served as base fertilizers, rape seed meal 1 tons/ha served as first top-dressing applied on 30 and 20 days after transplanting on the first and second crop, respectively and rape seed meal 1 tons/ha served as second top-dressing applied on 50 and 30 days after transplanting on the first and second crop, respectively, that rice yields were lower than that of other fertilizers treatments.
Key words: rice (Oryza sativa L.), organic fertilizer, top-dressing.
