中文摘要:
      为了秋闲田饲用甜高粱丰产丰收,探索其高产栽培技术。采用列区试验设计与软件IBM.SPSS.Statistics.v22 的LSD法,对秋闲田饲用甜高粱的种植密度与播种行距进行了单株生产力及其草产量的比较试验。结果表明:种植密度与行距对秋闲田饲用甜高粱单株生产力、草产量均具有重要影响。明确了秋闲田饲用甜高粱高产配套栽培技术的优化组合:单株生产力最大的优化组合为A1B4,即种植密度为7.50 万株/hm2 与播种行距为40 cm 的配置;获得最高产量的优化组合为A2B4,即种植密度为22.50 万株/hm2与播种行距为40 cm的配置。研究结果为秋闲田种植饲用甜高粱的生产实践提了供理论依据和技术支撑。
英文摘要:
      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 7.5×104 plants/hm2 and the line spacing was 40 cm; the optimal combination for maximum yield was A2B4, the planting density was 22.5×104 plants/hm2 and 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.
