【摘要】 1999～2002年,由广西甘蔗研究所和广西凤糖生化股份有限公司共同实施了“糖厂10月开榨原料蔗配套技术的研究与开发”项目(桂经贸字[1999]459号)。经过3年多的实施,项目取得了很大的进展,主要是:筛选了适合10月开榨所需的特早熟品种,如R0C16、R0C20、桂引选3号、轻引98-3和农林8号等;成功地进行了特早熟品种R0C16、R0C20、桂引选3号和轻引98-3的产业化开发,面积达18836hm~2:初步形成了适合10月开榨的配套技术体系,包括种植特早熟品种、调整植期、合理施肥、提早管理、使用催熟剂和加强砍运榨管理等;成功地开发了R0C16、R0C20、桂引选3号和轻引98-3的等品种的特早熟功能和糖厂资源功能,进行了10月25日开榨实践,取得良好的经济效益和社会效益。项目技术对提高糖厂经济效益、延长榨季、减轻可能的霜冻为害等具有重要意义。更多还原

【Abstract】 The project of the development and research of the raw cane’s technologies matching the grinding in Oct. was jointly conducted by Guangxi Sugarcane Research Institute and Guangxi Fengtang Biochemistry Share Limited Company in the cane area of Liucheng county from Jan., 1999 to May, 2002. The main achievements of the project have been obtained during more than 3 years’ practice. The varieties suitable for grinding in Oct. were screened, including ROC16, ROC20, Guiyinxuan3, Qingyin98/3 and NonglinS and so on. The varieties such as ROC 16, ROC20, GuiyinxuanS and Qingyin98/3 were mass extended, covering a total of 18836 hectares. The sugar content and maturing period of the 17 varieties (clones), domestic or introduced, were investigated. The early maturing capability of varieties such as ROC 16, ROC20, GuiyinxuanS, Qingyin98/3 and resources in the sugar mill were utilized, and the grinding on Oct. 25, 2001 was carried out successfully. The project’s economic and social benefit reached 113,728,000 yuans. The raw cane production technologies adapted to grinding in Oct. was formed, including planting early maturing varieties, adjusting planting period, rational application of fertilization, early management, the application of chemical ripener and the management of harvesting, transporting and squeezing. The project’s technology is important to enlarge economic profit, prolonging the grinding period and lessening the possible freeze injury of raw cane.更多还原
