摘要

本研究為探討夏季栽培甘藍之養分管理技術。於本場簡易設施內，以不同氮源型態之肥料及施用量作為處理，調查其對夏作甘藍生理之影響。試驗結果顯示，平地夏作甘藍，因氣溫較高，不利於葉球之發育；多量施用化學肥料或偏施銨態氮肥會增加葉片之含氮量，且易誘致頂燒症及內腐病等生理性病害，以致降低品質及可販售產量；而施用有機肥料則可增進植株耐病力，減少罹病率，提高葉球品質及產量。故甘藍之養分管理應著重有機肥料之利用，而以化學肥料為副，或減量施用化學肥料。

The experiment was conducted to study the effect of different types and quantity of nitrogen fertilizer on the growth, yield and physiology disorder of cabbage cultivated in Summer. The results showed that high temperature caused cabbage unable to grow and develop well. Both tipburn and heart-rot occurred when over-application of chemical fertilizers and ammonium type fertilizer, especially calcium cinamide, all these caused low yield. Whereas organic fertilizer and compound fertilizer treatments would improve quality and yield of cabbage.
