添加枯草桿菌轉殖株堆肥對小白菜生長效應之探討

Effects of Bacillus subtilis-treated Compost on Growth of Brassica rapa L. var. chinensis

本研究利用添加枯草桿菌轉殖株堆肥和其他自製堆肥施用於小白菜，探討堆肥對其園藝性狀和植體成分含量之影響。將堆肥之肥效分別以相當於1／2、1／4及1／8化肥之肥效估算進行施肥，不同肥料對小白菜生長之效應結果以1／8化肥肥效者最佳，1／4者次之。在自製堆肥中氮、磷、鉀養分濃度之比例以磷的含量偏高，需要配合氮肥及鉀肥的施用，不但可滿足小白菜生長養分平衡之需，尚可改善蔬菜廢棄物對環境所造成污染問題，亦能有益於土壤生產力之提升。 In this study, Bacillus subtilis-treated compost was used for the growth of Brassica rapa L. var. chinensis, and the compost efficiency and the growth were studied. The results showed that compost with 1/8 fertility equivalent to chemical fertilizer achieved the highest compost efficiency. The amount of N and K in this compost needed to be supplemented for N-P-K balance. The application of this compost is beneficial to the growth of Brassica rapa L. var. chinensis, reduces the waste products in vegetable processing, and increases the fertility of the soil; therefore, it is worth popularizing
