利用4个复播玉米品种和饲用甜高粱(大力士)在同等栽培管理条件下进行生产力和营养成分比较分析。结果表明,饲用甜高粱的鲜草产量最高,达135 258.9 kg/hm2,石玉901复播玉米产量高达70 642.6 kg/hm2,其次新玉29号(65 136 kg/hm2)、承担3号(54 433.35 kg/hm2)、新玉905号(52 026 kg/hm2)。饲用甜高粱的鲜草产量显著高于其它复播玉米品种,而且营养成分含量与其它玉米品种无显著差异。
Using four replicate corn varieties and sweet sorghum (Hercules) comparative analysis of productivity and nutrients under the same cultivation and management conditions. The results showed that the fresh grass yield of sweet sorghum was the highest (135 258.9 kg / hm2) and that of Shiyu 901 sowed corn was 70 642.6 kg / hm2, followed by that of Xinyu 29 (65 136 kg / hm2) (54 433.35 kg / hm2) and Xinyu 905 (52 026 kg / hm2). The fresh grass yield of forage sweet sorghum was significantly higher than that of other sowing corn varieties, and the content of nutrients was no significant difference with other maize varieties.
