Biomass Production from Sugarcane and Sweet Sorghum. Final Report

摘要

The results of a field study on growing sugarcane and sweet sorghum in the Lake Okeechobee area of Florida are reported. Two experiments were conducted on row-spacing of sugarcane and one on row-spacing of sorghum. There were no surprises in the data obtained in this year's sugarcane experiments. High biomass, sugar and fiber were produced both on sand and muck soils in south Florida. Yields were, as in previous years, higher for the narrow row spacing where solar radiation was better than in plant cane. Likewise it is greater for a second ratoon than for a first ratoon. Sweet sorghum produced well but not as well as last year due to a planting data which was 1 to 2 months late and to the wider spacings used to facilitate the trial of sugarcane harvesting equipment. Moisture is much more critical for sorghum than for cane. One experiment on muck suffered due to wet conditions. A second experiment on sand was lost due to lack of moisture. (ERA citation 07:017697)
