品种和种植密度对高粱主要农艺性状和产量的影响

Effects of variety and planting density on main agronomic characters and yield of Sorghum bicolor

为探索冀中南地区高粱[Sorghum bicolor(L.)Moench]种植的适合品种和适宜密度,以河北农业大学选育的品种农大红3号、自选品系矮秆1号、红茅梁6号选系为试验材料,采用双因素完全随机设计,设3个密度处理,对3个品种进行比较试验。结果表明,农大红3号产量显著高于其他品种;种植密度120000株/hm^(2)时,产量水平最高达10270.50 kg/hm^(2)。农大红3号适合冀中南地区种植,密度约120000株/hm^(2)可实现较高产量。

To explore the suitable varieties and density of Sorghum bicolor in central and southern Hebei province,the varieties Nong⁃dahong 3,self selected Dwarf 1 and Hongmaoliang 6 selected by Hebei Agricultural University were used as experimental materials.The two factor complete random design was adopted,and three density treatments were set up to compare the three varieties.The re⁃sults showed that the yield of Nongdahong 3 was significantly higher than that of other varieties;The planting density was 120000 plants/hm^(2),and the yield level was up to 10270.50 kg/hm^(2).Nongdahong 3 is suitable for planting in central and southern Hebei prov⁃ince.The suitable density of sorghum is about 120000 plants/hm^(2),which can achieve high yield.
