摘要
以沈农甜杂2号和辽甜3号为材料,研究了在天津生态条件下,甜高粱品种的丰产性和适应性。结果表明,2个品种在天津不同地区均能正常生长,平均生育期分别为130.8,132.4d,与品种原产地差异不大。沈农甜杂2号和辽甜3号同时具备生长势强、生物产量高(94335.5,94081.2kg·hm-2)、茎秆锤度高(16.36%,18.15%)及适应性强等优点。甜高粱品种在不同地区性状表现各异,在宁河地区综合表现最好。在天津的生态条件下,适合引进并推广沈农甜杂2号和辽甜3号。
With SNTZ No.2 and Liaotian No.3 as tested materials, abundant productivity and adaptability of sweet sorghum were studied in Tianjin ecological conditions. The results showed that the two varieties could grow normally in different areas of Tianjin. The average growth period was respectively 130.8, 132.4 d, and there was no significant difference between these areas and varieties origin. SNTZ No.2 and Liaotian No.3 both had strong growth, high biomass (94 335.5, 9 4081.2 kg.hm-2), high stem brix (16.36%, 18.15%) and strong adaptability. The two varieties showed different results in different areas, and both performed best in Ninghe area. SNTZ No.2 and Liaotian No.3 was suitable for introduction and extension in Tianjin ecological conditions.
