摘要
为筛选出适宜环渤海地区种植的BMR饲用高粱品种,2011年对来自美国以及澳大利亚的15个BMR品种与3个非BMR品种的饲用高粱品种进行了田间比较试验,系统测定并分析了与生产性能有关的植株生长高度、分蘖数、茎粗、鲜草产量、干草产量、鲜干比和茎叶比。结果表明:15个BMR品种与3个对照品种在生长性状和产量方面差异显著;BMR Elite和26837高粱在该地区可以做青贮利用,BMR Enroma苏丹草、SS2苏丹草、22053高丹草、PAC F8423高丹草在该地区可以多次刈割做青饲或者干草。这几个品种可以作为该地区的优良品种,利用适宜的方式推广应用。
In order to select the suitable BMR forage sorghum varieties around Bohai Sea, the field comparative study on 15 BMR sorghum varieties introduced from America and Australia, and 3 domestic varieties were carried out in 2011. The characteristics including plant height, tiller number, stem diameter, fresh yield, dry yield, ratio of fresh yield to dry yield and ratio of stem to leaf were tested. The results showed that there were significant differences in the growth characteristics and yield among 15 introduced varieties and 3 domestic varieties （ P 〈 0. 05 ） . BMR Elite and 26837 could be used as silage. Sorghum Sudanese BMR Enroma and SS2, and S. vulgarex S. sudanese BMR 22053 and PAC F8423 could be cut many times as greenfeed or hay. These varieties were suitable for spreading and planting around Bohai Sea.
