摘要

本研究目的在於探討有機肥料及石灰等土壤改良資材應用於洋桔梗栽培之影響效應。試驗處理包括蔗渣木屑堆肥20 t/ha、有機液肥20 L/ha/month及苦土石灰2 t/ha等組合成五級處理。試區設置於南投縣埔里鎮，於2007年5月定植及9月宿根連續進行兩期作洋桔梗栽培試驗。試驗結果顯示，施用蔗渣木屑堆肥、有機液肥及苦土石灰等處理，可以增進第一期夏作洋桔梗及宿根洋桔梗之植株株高、葉片數及葉寬等生育性狀，並可以增進第一期夏作洋桔梗及宿根洋桔梗之切花花枝長及花苞數等花卉品質特性，其中施用蔗渣木屑堆肥、有機液肥及苦土石灰等綜合處理相較於空白對照處理，可以增加第一期夏作洋桔梗切花採收期之洋桔梗總切花產量及洋桔梗A級切花產量，並可以增加宿根洋桔梗切花採收期植株存活率、洋桔梗總切花產量及洋桔梗A級切花產量。施用有機質肥料及苦土石灰等處理，可以提高土壤pH值及交換性鈣含量，並增加洋桔梗切花採收期葉片中磷及鈣含量。顯然，適當使用有機質肥料、有機液肥、苦土石灰等土壤改良資材，頗適用於洋桔梗栽培之應用參考。

The objective of this research is to evaluate the application of organic fertilizers and dolomite on the growth effects of lisianthus (Eustoma grandiflorum Shinn.). Field experiment was conducted with different treatments with bagase-sawdust compost (20 t/ha), organic liquid fertilizer (20 L/ha/month) and dolomite (2 t/ha) at Puli town, Nantou county. The first crop started on May and the ratoon on September at 2007. The results showed that the growth characteristics of lisianthus (height of shoot, number of leaf, width of leaf) and the qualities of cut-flower (length of flower stalk, number of flower) have the positive responses on the treatments of bagase-sawdust compost, organic liquid fertilizer and dolomite at both of first summer crop and ratoon. The survival rate, yield of cut- flower and class A number of cut-flower at first summer crop of lisianthus on the treatment of bagase-sawdust compost, organic liquid fertilizer and dolomite were higher than that on the control by 10.3%, 10.4% and 10.7%, respectively. The survival rate, yield of cut-flower and class A number of cut-flower at ratoon crop of lisianthus on the treatment of bagase-sawdust compost, organic liquid fertilizer and dolomite were higher than that on the control by 41.9%, 42.3% and 48.7%, respectively. The application of bagase-sawdust compost and dolomite could increase the pH and the content of calcium of soil. The contents of leaf P and Ca were also increased at cut-flower harvest stage of lisianthus. However, the application of bagase-sawdust compost, organic liquid fertilizer and dolomite can be useful and suitable for the cultivation of lisianthus.
