分析勐海地区常见27个甘蔗品种从2014年12月至2015年3月蔗糖品质的变化。结果表明:随着甘蔗的成熟,其品质在成熟中后期最好,这时期收获的甘蔗纤维分较低,蔗汁糖分、甘蔗蔗糖分、蔗汁磷酸值较高。该地区种植的甘蔗,随着海拔的升高,蔗汁锤度、蔗汁糖分、甘蔗蔗糖分、蔗汁磷酸值下降。 The change of sucrose quality of 27 common sugarcane varieties in Menghai area from December 2014 to March 2015 was analyzed. The results showed that with the maturity of sugarcane, its quality was the best during the middle and late stages of maturity. The fiber content of sugarcane harvested at this period was lower, and the sugar content of cane sugar, cane sugar content and cane sugar content were higher. Sugar cane planted in this area, with the elevation, cane juice brix, cane sugar, sugar cane sugar, cane juice phosphate value decreased.
