引言据统计,1981～82年度福建省甘蔗的蔗糖份比上年发下降0.86绝对值,1982～83年度又下降0.65绝对值。由于蔗糖份下降,两年就损失白糖3～4万吨。造成蔗糖份下降的原因有气候变化引起甘蔗迟熟、低糖;栽培管理偏施、迟、重施化学氮肥;品种搭配和园艺管理等方面。国内外曾报导,增甘磷 Introduction According to statistics, the sucrose content of sugar cane in Fujian Province decreased by 0.86% from 1981 to 2001, and decreased by 0.65% in 1982-83. Due to the declining of sucrose, 3 to 40,000 tons of sugar are lost in two years.
