Popularizing virus-free sugarcane seedlings in large areas in Guangxi

(agricultural Wealth Network) recently, the reporter learned at the demonstration site of sugar cane health seedling production in Maping Township, Xiangzhou County, Guangxi that, according to the results of on-site acceptance, the theoretical yield of NTSC 22 virus-free healthy seedling field is 8 tons per mu, which is 42.9% higher than that of non-virus-free seedling field. Under the condition of constant input cost, planting sugarcane virus-free healthy seedlings can increase the economic income of sugarcane farmers by more than 200 yuan per mu.

It is understood that compared with conventional seedlings, sugar sugarcane stems increase by 15.1% / 52.1% and sucrose content by 0.12% / 1.71% (absolute value). At present, popularizing the cultivation of virus-free healthy seedlings has become the most effective technology for preventing and controlling the sexual degradation of sugarcane varieties.

Guangxi regards the promotion of virus-free healthy seedlings of sugarcane as an effective way to further increase the total production of sugarcane and the income of sugarcane farmers. since 2007, 9 million yuan has been invested. Relying on Guangxi Sugarcane Research Institute and Liucheng County Sugarcane Research Center for sugarcane virus-free healthy seedling breeding and demonstration. After two years of project implementation, a total of 6 million virus-free healthy seedlings have been propagated and promoted in the region, of which 1.5 million were planted in the first half of 2007-2008 and 2.5 million in the first half of 2009. About 1.5 million virus-free seedlings are being cultivated and can be planted in the field by the end of the year. At present, nearly 10,000 mu of virus-free second-generation seedlings have been planted in the whole region, and the planting area has reached more than 10 main sugarcane producing areas.
