众所周知,甘蔗品种的优劣,对工农业生产的效益影响甚大。例如1986年梅山糖厂的试验,粤糖71/355比粤糖57/423增产14.6%,在不增加任何成本的情况下亩农业收益增加68.1元;蔗糖分增加0.405%(绝对值),亩含糖量增加343.31斤,在不增加成本的情况下吨蔗产糖多7.1斤,即吨蔗增加税利3.55元。但梅山糖厂蔗区品种过于单一,95%属迟熟品种,为改变这种被动局面,近几年来,我们在引种工作中取得了一些成绩和教训,现将其实践和体会作如下总结。
As we all know, the merits of sugarcane varieties, the benefits of industrial and agricultural production have a great impact. For example, in the trial of Meishan Sugar Mill in 1986, the yield of Yugu sugar 71/355 increased by 14.6% compared with that of Yugosel 57/423, and the agricultural income increased by 68.1 yuan without any increase in cost; the increase of sucrose by 0.405% (absolute value), mu An increase of 343.31 pounds of sugar content, without increasing the cost of tons of sugarcane produced more than 7.1 kg, that is, tons of sugar to increase tax 3.55 yuan. However, the varieties of sugarcane in Meishan Sugar Factory are too single and 95% are late-maturing varieties. In order to change this passive situation, in recent years, we have made some achievements and lessons in the introduction work. Now we summarize their experiences and experiences as follows.
