| 摘要： 中部地區番石榴栽培面積約有1500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。本年度進行果園生產環境改善，施用不同有機質及土壤改良劑，探討對改善果園土壤及番石榴果實品質之效益。並進行不同程度留果摘心處理，觀察對番石榴果實生長與品質之影響。預期效益為，以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，生產優質安全的果品，提昇產業之發展與市場競爭力，並拓展國內外市場。The planted acreage of guava in Taichung district area was 1500ha. 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 year, the orchard production environment is to be improved by the application of organic materials and soil conditioner, the improvement of the orchard soil and guava fruit quality will be discussed. The investigation on the guava fruit growth and quality after different leaf/fruit ratio treatment will also conducted. The 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 extension, the production cost can be lower down and produce high quality guava fruits, the marketing competitiveness is enhanced too. |
