甘蔗品种与原料蔗生产系统优化技术在云县糖厂的实践

云南省云县糖厂自实施甘蔗品种与原料蔗生产系统优化技术后,每年吨蔗产糖量增幅达8%～19%。3～4年后,产蔗量接近翻番,而蔗区甘蔗品种仍与实施前一样,以传统品种桂糖11号、川糖61-408、粤糖79-177等为主。该县品种改良方法与传统方法有本质上不同,形成了一种能最大限度消化利用现有甘蔗品种增糖增产潜力的品种改良运作机制,产糖率和产蔗量不断提高。这是通过原料蔗优化砍运和蔗区品种优化布局2条技术途径实现的。

Systematic Technique of Sugar and Cane Yields Improvement in Sugarmills of Yun County,Yunnan Province

A systematic technique to improve cane and sugar yields was applied in sugar mills in Yun County and an increase of 8%~19% in sugar yield per ton cane was obtained. After 3 or 4 years of application, total cane yields almost doubled while growing the same varieties as the ones used before, such as GT 11, CT 61-408, YT 79-177, etc. This systematic technique was totally different from the usually applied variety improvement methods. It can unearth the potential of the varieties currently grew locally, and maximize both cane and sugar yields. This was obtained by means of two ways： optimized harvesting and optimized variety patterns.
