| 摘要： 中部地區番石榴栽培面積約有1727公頃，一般果農均未塑造適當的樹型，樹勢不均一，以致生產力及果實品質不易提昇。本試驗將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肥培耕作處理方法，尋求適當管理技術以提高番石榴之生產力及果實品質。本省枇杷大部份種植於地力稍差的山坡地，擬就不同氣候環境下之結果枝形質、花芽分化、開花生理與習性、果實生長過程等基本觀察著手，並探討以遮光、降溫等促進花芽形成之方法，以尋求枝條生育管理、調節花期及提高果實品質的可行方法。預期效益為，提早枇杷花芽分化，並促使早花之著果良好且穩定產量，可提早產期並延長供貨期，加農民收益。The planted acreage of guava in Taichung district area was 1727 ha. 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 fertilization treatments are applied to matured guava trees. The expected results of proper technique can be used to enhance the productivity and fruit quality of guava. Most of the loquat in Taiwan is planted in the slop land with low fertility. In this study, the shoot quality, flower bud formation, flowering physiology and fruit growth are observed. The treatments that induce flower bud formation, such as shading and temperature alleviating, were applied to the loquat trees, the tree management and orchard practice on production season regulation and fruit quality enhancement will be discussed. The expected results of proper technique can be used to advance the flower bud formation and fruit setting and to prolong the marketing period of loquat. |
