Abstract
The effects of different potassium and sodium levels on the growth of Taisugar No. 22 (ROC22) were studied by potted nutrient solution-sand culture experiment in this paper. The results showed that under low potassium stress (0 mmol/L) supply, the proper application of sodium could significantly promote photosynthesis of sugarcane and dry matter accumulation, reduce root shoot ratio and promote shoot growth. When low potassium (0.2 mmol/L) was applied, the proper application of sodium could reduce the root shoot ratio of sugarcane. When high potassium (2 mmol/L) was applied, the proper application of sodium could significantly promote the growth of sugarcane root and increase root shoot ratio. In the case of low potassium or high potassium, the rational application of sodium can promote photosynthesis of sugarcane, while excessive sodium can inhibit photosynthesis. Thereby, sodium can be used as a substitute for partial potassium to promote the growth of sugarcane in the soil with low available potassium and water-soluble sodium.
