摘要

Abstract

To obtain high harvest of forage sweet sorghum in autumn idle land, the authors explored its high yield cultivation methods. A comparative test of the effects of line spacing and planting density on plant productivity and grass yield of forage sweet sorghum in autumn idle land was conducted with split-plot design and LSD method of IBM.SPSS.Statistics.v22 statistics software. The results showed that the planting density and line spacing had important influence on plant productivity and grass yield of forage sweet sorghum in autumn idle land.The optimal combination for high-yield cultivation was obtained:the optimal combination of single plant productivity was A1B4,the planting density was 7.5×104plants/hm2and the line spacing was 40 cm;the optimal combination for maximum yield was A2B4, the planting density was 22.5×104plants/hm2and the line spacing was 40 cm. The results provide a theoretical basis and technical support for the production of forage sweet sorghum in autumn idle land.
