摘要
为筛选出适宜西辽河平原夏播的饲用甜高粱品种及鉴定指标,在通辽市农牧业科学院,于2021年麦类饲草收获后播种6个饲用甜高粱品种,分别在9月10日和9月23日两个时期收获,测定农艺性状(产量、干鲜比、叶面积、叶面积系数、株高、茎粗、茁壮度、分蘖数)和营养品质(糖锤度、可溶性糖、淀粉、CP、EE、粗灰分、ADF、NDF、RFV),采用灰色关联分析法筛选最佳饲用甜高粱品种。结果表明,9月10日收获饲用甜高粱品种综合排序为:辽甜13号>辽甜1号>晋牧4号>晋牧3号>晋牧1号>通甜1号;9月23日收获饲用甜高粱品种表现排序为:辽甜13号>辽甜1号>晋牧4号>晋牧1号>通甜1号>晋牧3号。建议西辽河平原地区夏播的饲用甜高粱品种首选辽甜13号、辽甜1号和晋牧4号。
In order to select suitable forage sorghum varieties and identification indicators for summer sowing in the West Liaohe Plain,six forage sweet sorghum varieties were sown at the Agricultural and Animal Husbandry Science Research Institute of Tongliao City in 2021 after harvesting wheat forage.They were harvested on September 10 and September 23,respectively.The agronomic characteristics(yield,dry fresh ratio,leaf area,leaf area coefficient,plant height,stem diameter,robustness,tillering number)and nutritional quality(sugar brix,soluble sugar,starch,CP,EE,crude ash content)were measured ADF、NDF、RFV,Using grey correlation analysis method to screen the best feed sweet sorghum varieties.The results showed that the order of harvested sweet sorghum varieties for feed on September 10th was as follows:Liaotian 13>Liaotian 1>Jinmu 4>Jinmu 3>Jinmu 1>Tongtian 1;The order of harvested sweet sorghum varieties for feed on September 23 is:Liaotian 13>Liaotian 1>Jinmu 4>Jinmu 1>Tongtian 1>Jinmu 3.It is recommended to choose Liaotian 13,Liaotian 1,and Jinmu 4 as the preferred summer sowing sorghum varieties in the West Liaohe Plain region.
