Abstract
The optimum dosage of nitrogen and potassium fertilizer of different sugarcane varieties by different nitrogen and potassium ratio was determined. YT55, GT32 and Liucheng05-136 were selected as representatives of three strains, 4 different nitrogen and potassium ratio(low level 375 kg/hm2, high level 450 kg/hm2) were plotted to study the difference of nitrogen and potassium fertilizer on sugarcane growth, yield and nutrient uptake. The results showed that different nitrogen and potassium ratio had significant different effect to the emergence and tiller of different strains of sugarcane. performance. Low N, K level were beneficial for YT55's production, high N, K level were beneficial for GT32's production, high K level was beneficial for Liucheng05-136's production, but the difference was not significant. The total nitrogen and total phosphorus content were the highest in low N, K level of sugarcane, and the difference was significant. In different N, K levels, stems of different sugarcane varieties differed in total potassium content, and the difference was significant. At strong acidity lateritic red soils, more attention should be paid to ratio of N, K for different strains of sugarcane during seedling, tillering stage to facilitate the growth of sugarcane. But in the latter part of the growth stage, N, K only had a significant effect on single stem weight and was not the main obstacle affecting production in the region.Other nutrients or soil improvement was needed to increase cane production.
