台湾省过去七年间收获甘蔗的蔗糖含量已急剧地下降,尤其是在1975/76年榨季更为明显,与过去十年间平均糖的回收率11.78%比较,达到了9.71%的最低记录,(如图1)(略)。为了改变这种被动局面,台湾糖业公司糖业研究所在这一年开始提出了一个范围广泛的研究计划,但对产糖量下降的原因仍不清 The sucrose content of Taiwan’s sugarcane harvested in the past seven years has dropped sharply, especially in the 1975/76 crop season, reaching a record low of 9.71%, compared with the average sugar recovery of 11.78% over the past decade. ( Figure 1) (omitted). In order to change this passive situation, the Sugar Research Institute of Taiwan’s Sugar Company started a wide-ranging research project this year, but the reasons for the decline in sugar production remain unclear
