摘要

我國荔枝產業長期以來深受品種少、產期集中、優良品種不易栽培且成本高、果實不耐貯藏等問題所困擾。農業試驗所所育成的7個品種，可把產期從當前集中於5-6月底的現象，藉有計畫性的品種更新將產期調節至3-8月中旬，其中盛產期可達3個月。此外，‘玉荷包’的產期調節技術，可使產期由南部恆春的5月上旬，延長至中部的7月上旬。藉由品種多樣化，及產期調節技術雙重的應用，使市場供需趨於平衡，並可分散勞力，降低生產成本，減輕氣象因素所造成的風險，對增加農友的收益有很大的幫助。

The main constraint in the litchi industry in Taiwan is the short production season lead to the imbalance between supply and demand in market, due to 'Hak Ip' planting too much. The 7 novel varieties released from Taiwan Agricultural research institute, have different fruit maturity seasons and good fruit quality. Based on the policy of the 'right cultivar for the right land' cultivate them in proper ecological regions will effectively adjust the current production period which are concentrated in late May and June extend to the period from late March to mid-August, it will match market requirements. Furthermore, researcher have developed cultural technology to adjust production period which apply it for 'Yu Her Pau' can make the period from early May in Hengchun, which locate in the most southern township of Taiwan, extend to early July in central Taiwan.
