摘要

為瞭解堆肥及不同土壤改良資材對蘿蔔產量及地力之影響，於南投縣埔里鎮及南投市兩地強酸性紅壤試驗結果，顯出施用堆肥或石灰類土壤改良資材對蘿蔔生育及產量均有顯著效果，其中以S-H添加物及矽酸爐渣處理之效果最佳，平均產量可達55.6及55.0t/ha，增產率為6.4%及5.3%。且施用土壤改良資材可以提高土壤pH值，改良土壤酸性，增加土壤中磷、鉀、鈣有效性，降低鐵含量，促進蘿蔔生長。

In order to understand the effect of using soil amendment on the yield of radish and soil fertility in acid soil, the field experiments were carried out at Puli and Nantou. Results showed that there were significant effects on the growth and the yield of radish in the applicaton of organic compost and soil amendment. The yield of radish in the treatment of S-H mixture (800 kg/ha) and basic slag (2000 kg/ha) were the best, which was 55.6 t/ha and 55.0 t/ha, and the increased rate were 6.4% and 5.3%, respectively. By amending the soil with soil amendment, it could increase soil pH and the available of soil P, K, Ca, but reduced the contents of soil Fe. Obviously, soil fertility was well improved by soil amendment.
