摘要: 番石榴富含維生素C,週年生產,外銷量逐年增加。本試驗以提升並穩定番石榴品質為目標。擬利用不同材質進行果實套袋、修剪、肥培管理,減緩夏季果實生長過快,以提升夏果品質及耐貯運能力,並穩定週年果實品質。鎂為葉綠素之主要構成元素,對氨基酸和維生素的形成有重要幫助。鎂亦是多種酵素的活化劑,影響碳水化合物的形成。鈣元素和果實質地相關,硬度較低的果實,鈣含量亦較低。線蟲為害為番石榴栽培之重要損耗,常造成植株死亡,若能建立良好防治策略,可使植株健化,並提升果實品質,減少損耗。 本試驗擬建立夏季外銷供果園生產模式,將葉面施肥及肥培管理標準化,並建立台灣番石榴外銷採前及採後處理流程,以及建立番石榴線蟲非農藥防治策略。Guava is rich of Vitalmin C, its annual production yield and exporting quantities are gradually increasing in Taiwan. This research aimed to promote and stablize the fruit quality of guava. Through different bagging materials, pruning techniques, and foliar fertilization may avoid the summer fruit growing too fast, and promote the quality and storage life of summer guava fruit. Magnesium is the main element to construct the chlorophyll, and is important for amino acid and vitalmin formation. Also, it is the activator for many kinds of enzymes, influencing the synthesis of carbohydrate. Calcium has close relation to fruit texture. The fruit with lower firmness often being less in calcium content. Nematode is one of the severe pest impact of guava, and often cause death of plant. To strengthen the plants, promote fruit quality and reduce economic loss, a suitable stretegy for nematode control is needed. Our project is to establish the production model in summer for exporting orchard, standerdize the the foliar and soil fertilization management, and establish the procedure of pre- and post-harvest treatment for exporting guava. For the nematode, we aimed to estblish a non-pesticide contol strategy for guava production.
