台湾地区幅员狭小,利用区域气候条件调节果树产期的效果有限,往往一种果树的收获期集中于某一短期间。尽管,台湾果树种类众多,但盛产期大部集中于夏秋季节,造成市场水果供应不均衡,冬季供应紧张,不能满足销费需求,而夏季水果过剩,价格暴跌,果贱伤农,水果产业的发展受到一定的限制。因此,如何人为控制果树生育,适度调节水果收获期,使之周年均匀供市,是台湾进一步发展果树产业的一大课题。70年代,台湾开始葡萄、梨等产期调节研究,80年代,台湾农政当局为加强这一研究,1983年“农业发展委员会”成立了果树产期调节
In Taiwan, the area is limited and the effect of adjusting the fruit-producing period of fruit trees by using regional climatic conditions is limited. The fruit-harvesting period of a fruit tree tends to be concentrated in a certain short period of time. Although there are many types of fruit trees in Taiwan, most of the rich areas are concentrated in summer and autumn, resulting in an unbalanced supply of fruits in the market and tight supply in winter, which can not meet the demand for selling fees. In summer, excess fruits, plummeting prices, Development is subject to certain restrictions. Therefore, it is a major issue for Taiwan to further develop the fruit tree industry in order to control the childbearing of fruit trees, adjust the harvest period of fruits moderately, and make it available evenly for the anniversary. In the 1970s, Taiwan began to study the regulation of the production period of grapes and pears. In the 1980s, in order to strengthen this study, Taiwan’s agricultural authorities set up the “Agricultural Development Committee”
