摘要
广西甘蔗良种繁育推广体系的建设实施,对加快甘蔗优良新品种的推广做出很大贡献。甘蔗种苗工厂化生产是甘蔗生产必经之路,我国种苗工厂化生产还处于探索阶段,与国外先进甘蔗生产国相比还有很大差异。本文从广西甘蔗良种繁育推广体系产生背景和建设现状分析了存在的主要问题是:甘蔗良种推广体系还需完善,甘蔗良种推广模式不健全,良种繁育基地建设进度相对滞后、缺乏育繁推一体化、供种能力严重不足。提出的发展措施是:进一步完善甘蔗良种繁育基地经费预算、申报、考核制度,加强甘蔗良种田间繁育关键技术研究,完善甘蔗新品种推广模式,探索甘蔗健康种苗工厂化生产。
Implementing elite sugarcane varieties breeding and popularizing system in Guangxi has made great contributions to speed up the popularization of elite sugarcane varieties.The only way to sugarcane production is to industrialize the seed cane production.But,the industrial production of seed cane in China is still at groping stage at present and there is a large gap as compared with advanced sugarcane planting countries.Based on background and status of sugarcane breeding and extension system in Guangxi,the main problems were analyzed in this paper.The sugarcane improved variety extension system still needs to be improved,the model for improved sugarcane variety extension is imperfect,and the construction progress of the improved sugarcane variety breeding base had not been well developed.There were serious shortage of seed supply capacity,and lack of integration among breeding and propagation and popularization.The development measures were suggested as follows:to further improve the budget,application and examination system of sugarcane breeding base;to strengthen the research on the key techniques of sugarcane multiplication under field conditions;to improve the extension mode for new sugarcane varieties;and to explore the factory production of healthy cane setts.
