摘要

為瞭解不同豬糞種類、施用量及施用時期對甘藍生育及地力之影響，於彰化縣埤頭鄉鹼性粘板岩沖積土及台中縣外埔鄉酸性組壤進行試驗。結果顯示，不論施用乾豬糞或石灰豬糞均能增加土壤有機質含量、有效性磷及交換性鉀含量，並能增進保水力、改善土壤硬度等，且乾豬糞的效果優於石灰豬糞。在施用量處理上，施用20 t/ha對增進土壤肥力及甘藍產量的效果優於10 t/ha，但在20 t/ha用量處理，土壤重金屬含量增加，惟仍屬於中等級範圍內。不同施用時期處理對甘藍定植存活率之影響極為顯著，而以甘藍定植前二週施用所獲得的甘藍定植存活率及單位面積產量最高。

The effect of application rates and times of different hog wastes on soil fertility and the yield of cabbage was studies on alkaline slate-alluvial soil at Pitou and acidic red-earth at Waipu. The results showed that the application of both fry hog waste and lime hog waste could increase the contents of soil organic matter, available P, exchangeable K, water and also decrease soil hardness. However, as concerned the effect on soil fertility and the yield of cabbage, treatment of dry hog waste was the best than that of lime hog waste and the application rate of 20 t/ha was better than 10 t/ha. When applied 20 t/ha of hog waste, the contents of soil heavy metals might increase from lower to medium range. There was significant effect of application time of hog waste on the survival rate of cabbage after transplanting. Result slowed that the application time of hog waste when applied 14 days before transplanting had the highest survival rate and yield of cabbage after trans-planting.
