Variation among Sugarcane Varieties in Nutrient Uptake and Utilization under Mechanized Production

doi:10.3969/j.issn.1000-2561.2020.05.001

Abstract

Abstract:

From the viewpoint of efficient production, a field experiment was conducted to investigate the dry matter accumulation, nutrient accumulation and utilization of four sugarcane varieties, including plant cane and first ratoon under mechanization. The stalk dry matter accumulation and total dry matter accumulation of ‘Guitang 42’ were the highest, which was more than that of the other varieties for 819.66-4273.69 kg/hm ² and 1232.14-5863.38 kg/hm ², respectively, but and that for ‘Guiliu 05136’ and ‘Guitang 29’ were lower. The total accumulation of N, P₂O₅ and K₂O from different varieties was 133.79-196.82, 35.99-47.29 and 233.31-311.57 kg/hm ², respectively, and that of ‘Guitang 42’ was higher than ‘Guiliu 05136’. N, P₂O₅ and K₂O requirement per 1 t sugarcane stalk of different varieties were 1.57-2.03, 0.43-0.48 and 2.72-3.21 kg, respectively, and that of ‘Guiliu 05136’ was lower. The economic efficiency and physiological efficiency of N, P₂O₅ and K₂O were the highest with ‘Guiliu 05136’. The dry matter accumulation, nutrient accumulation and nutrient efficiency of ratoon cane were higher than that of planting cane. In conclusion, the biological production of ‘Guitang 42’ is better, and the nutrient efficiency of ‘Guiliu 05136’ is high.

Key words: sugarcane, dry matter, nitrogen, phosphorus, potassium
