蓮霧產期調節研究發展與產業調適研究

蓮霧為臺灣南部重要熱帶果樹之一，高屏地區為主要產地，產期為11月起至翌年7月，另中北部宜蘭、嘉義及南投等地區為次要產地，產期為8-11月，蓮霧產業可依品種別、產地別及產期調節等方式達到全臺周年生產，供應臺灣市場消費需求。目前外銷量也逐漸成長至5.6%，仍以中國大陸地區為主。近十年蓮霧栽培面積已減少2,500公頃，105年則為3,646公頃，歸咎原因為果實品質易受環境因素影響而不穩定，近年來更常因8-9月颱風災害，嚴重破壞蓮霧園相，降低產期調節後之催花成功率，也造成抽梢問題控管不易而影響產量與果實品質。因此需適時適地調整耕作管理方法、樹體養分及搭配各類田間管理模式等方式，方能於產期調節作業後，穩定生產符合市場需求之果形大、果色鮮美及糖度高特色果品，提高蓮霧整體競爭力。

Wax apple is one of important tropical fruit trees in southern Taiwan. Kaohsiung city and Pingtung county are major production areas, and Yilan, Chiayi and Nantou counties followed by. Nowadays, Taiwan wax apple industry reach year-round production base on varieties, production area and off-season production technique. Not only could support local market, but also export to mainland China that export amount rise to 5.6%. However, production area have reduced 2,500 hectares in this decade, production area is 3,646 hectares in 2016. The issue of unsteady quality is caused by environments, such as typhoon, chilling injury and heavy rain etc. Typhoon in recently almost disaster in August and September, and would affect wax apple orchard and reduced flower buds forcing successful ratio. The unstable fruit quality be effected by uncontrolled new shoots after disaster. The solution method listed as follow: adjusted offseason production technology ex. shading or flooding time, tree vigor and field management practices that would product big fruit size, high TTS, good flesh color to fit customers’ need and competitiveness.
