摘要
甘蔗糖业是广西支柱产业之一。文章概括总结了广西甘蔗产业和技术创新发展的历程、主要成果和经验,阐明了甘蔗种质创新和优良新品种选育应用、旱地甘蔗高产高糖高效栽培技术体系创建与应用为广西甘蔗产业从小到大、从弱到强发展提供重要技术支撑,并指出了当前广西甘蔗产业及甘蔗育种和栽培技术研发应用上存在的问题。提出要进一步加强引进国内外甘蔗品种和种质资源,以及野生甘蔗种质资源的收集、研究与利用,创制创新性种质用于杂交育种,同时加强杂交技术和选种技术研究,提高甘蔗育种效率;加强农机农艺配合研究,推进甘蔗生产全程机械化;利用甘蔗的生物固氮特性,减少氮肥施用量;加快甘蔗健康种苗生产技术的应用来提高种苗质量;选用宿根性强的甘蔗品种及加强管理,延长甘蔗宿根年限,降低生产成本。
Sugar industry is one of the pillar industries in Guangxi. The paper summarizes the course,main achievements and experiences of the development of the sugarcane industry and technology innovation in Guangxi, expounds the application of the sugarcane germplasm innovation and the excellent new variety breeding, the establishment and application of the high-yield, high-sugar and high-efficiency cultivation technology system of the sugarcane in the dry land is growing for the sugarcane industry in Guangxi.It provides important technical support from the weak to strong development, and points out the existing problems in the research and development of the industry, breeding and cultivation technology of sugarcane in Guangxi. It is proposed to further strengthen the introduction of the domestic and foreign sugarcane varieties and the germplasm resources, as well as the collection, research and utilization of the wild sugarcane germplasm resources, and create innovative species. The method has the advantages that the quality is used for cross breeding, the hybridization technology and the seed selection technology are enhanced, the sugarcane breeding efficiency is improved, the agricultural cooperation of the agricultural machinery is enhanced, the whole process of the sugarcane production is promoted, the biological nitrogen fixation property of the sugarcane is utilized, and the application amount of the nitrogen fertilizer is reduced;The application of the technology for accelerating the production of the sugarcane health seedlings is accelerated, the quality of the seedlings is improved, the sugarcane varieties with strong roots are selected, the management is enhanced, the service life of the sugarcane is prolonged, and the production cost is reduced.
