摘要
广西是我国的主要甘蔗产区,总面积和产量均占全国的60%以上,但蔗区土壤肥力低,氮肥施用量大,甘蔗生产成本居高不下,缺乏国际竞争力。通过甘蔗的固氮特性,结合有性杂交育种的途径,选育具有较强固氮能力的甘蔗新品系,最终育成具有固氮特性的高产高糖甘蔗新品种,来大幅度降低氮肥施用量,减少生产成本,提高蔗糖产业和能源产业的竞争力,对我国甘蔗种植业的健康发展有积极意义。
Guangxi is the main sugarcane production area in China,occupying for more than 60%of the total area and output of the country.However,the sugarcane area has low soil fertility,large application of nitrogen fertilizer and large annual application of nitrogen fertilizer,high production cost of sugarcane and lack of international competitiveness.Sugarcane nitrogen-fixing features,combined with hybridization breeding,selecting the clone which has the strong ability of nitrogen-fixing,breeding high yield and high sugar cane varieties finally,features to reduce nitrogen using,reduce the production cost,and improve the competitive power of the sugar industry and energy industry.It is positive significance for the healthy development of the sugar cane planting industry in our country.
