摘要
在新疆阿拉尔市,以6个不同甜高粱(Sorghum bicolor‘Dochna’)品种为研究对象,在不同时间节点进行刈割,分别测定甜高粱的产量和营养成分,为确定适宜的栽培品种和刈割期提供理论支撑。结果表明,兼顾产量与营养品质,6个甜高粱品种适宜的刈割时间为7月27日;该时期,6个甜高粱品种的产量由高到低依次为大力士、青贮大师、FS3501、F10、F430、F29;粗蛋白质含量由高到低依次为大力士、F10、F430、FS3501、F29、青贮大师;淀粉含量由高到低依次为F29、FS3501、大力士、F10、F430、青贮大师;酸性洗涤纤维含量由高到低依次为FS3501、F29、F10、大力士、F430、青贮大师;半纤维素含量由高到低依次为FS3501、大力士、F29、青贮大师、F430、F10。综合比较,在6个品种中,大力士、青贮大师的产量及主要营养成分表现优良,适宜在阿拉尔市种植。
In Alar City,Xinjiang Province,six different sweet sorghum(Sorghum bicolor‘Dochna’)varieties were mowed at different time nodes to determine the yield and nutrient composition of sweet sorghum,which provided theoretical support for determining the appropriate cultivar and mowing period.The results showed that,considering both yield and nutritional quality,the suitable mowing time for 6 sweet sorghum varieties was July 27.During this period,the yield of the six sweet sorghum varieties from high to low was Dalishi,Qingzhudashi,FS3501,F10,F430 and F29;the crude protein content from high to low was Dalishi,F10,F430,FS3501,F29 and Qingzhudashi;the starch content from high to low was F29,FS3501,Dalishi,F10,F430 and Qingzhudashi;the acid detergent fiber content from high to low was FS3501,F29,F10,Dalishi,F430 and Qingzhudashi;the hemicellulose content from high to low was FS3501,Dalishi,F29,Qingzhudashi,F430 and F10.By comprehensive comparison,among the six varieties,the yield and main nutrients of Dalishi and Qingzhudashi are excellent,which are suitable for planting in Alar City.
