| 摘要： 中部地區番石榴栽培面積約有1,477公頃，一般果農均未塑造適當的樹型，因此樹勢不均一，以致植株生產力及果實品質不易提昇。本試驗從幼年樹塑造良好樹型以促進生產力；在成年樹利用不同修剪方法、疏果及不同肥培方式等處理，調整株高及枝幹分佈，比較不同耕作處理之產能及果實品質。預期效益為，從幼年樹養成適合樹型，以穩定生產力，並尋求適合之修剪摘心及留果方式與有機肥等耕作處理方法，尋求適當管理技術以提高番石榴之生產力及果實品質。建立番石榴栽培管理技術標準化作業流程，可降低生產成本，生產優質安全的番石榴，增加產品市場競爭力，進而提昇產業之發展，並拓展國內外市場。The planted acreage of guava in Taichung district area was 1,477ha. The farmers usually did not train a good tree shape for production, consequently the tree vigor is uneven and the productivity and the fruit quality are not easy to improve. In this study, the tree shape was established in the young trees to enhance the productivity. The combinations of different pruning, fruit-thinning and organic matters are applied to matured guava trees. The expected results of proper technique can be used to enhance the productivity and fruit quality of guava. The establishment of the high quality and safety production system for guava can build up a complete system of cultural management and production technique standard. After the extension on production practice, the production cost can be lower down and produce high quality guava fruits, the marketing competitiveness is enhanced too. |
