近几年来,内蒙西部地区甜菜糖分含量日趋下降,已成为目前甜菜生产和制糖工业面临的突出问题之一。一些地区为了提高糖分,在甜菜栽培管理中采取了增施P肥、控制N肥施用量、适时喷施K肥等措施,但效果不一。有些文献资料还有“采用喷施增甘膦、提高甜菜糖分”的方法和效果的报导。为了明确施肥对甜菜含糖量的影响,1979年我们也以上述措施为试验因子,探索
In recent years, the sugar content of beet in western Inner Mongolia has been declining gradually, and it has become one of the prominent problems in sugar beet production and sugar industry. In order to increase the sugar content in some areas, some measures such as increasing P fertilizer, controlling N fertilizer application and spraying K fertilizer in a timely manner have been adopted in the management of beet cultivation, but the results are different. Some references also include reports on methods and effects of “spraying glyphosate and increasing beet sugar”. In order to clarify the impact of fertilization on the sugar content of sugar beet, 1979 we also use the above measures as a test factor to explore
