【摘要】 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120 000株/hm~2时,产量水平最高达10 270.50 kg/hm~2。农大红3号适合冀中南地区种植,密度约120 000株/hm~2可实现较高产量。更多还原

【Abstract】 To explore the suitable varieties and density of Sorghum bicolor in central and southern Hebei province,the varieties Nongdahong 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 results showed that the yield of Nongdahong 3 was significantly higher than that of other varieties;The planting density was 120 000 plants/hm~2,and the yield level was up to 10 270.50 kg/hm~2. Nongdahong 3 is suitable for planting in central and southern Hebei province. The suitable density of sorghum is about 120 000 plants/hm~2,which can achieve high yield.更多还原
