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 suitable BMR sorghum cultivars planted in the Bohai Rim region, a field experiment was conducted on 15 sorghum varieties from 15 BMR breeds in the United States and Australia and 3 non-BMR breeds in 2011, Plant height, tiller number, stem diameter, fresh grass yield, hay yield, ratio of fresh to dry and ratio of stem to leaf. The results showed that there were significant differences in growth traits and yield among 15 BMR varieties and 3 control cultivars. BMR Elite and 26837 sorghum could be used as silage in this area. BMR Enroma sudangrass, SS2 sudangrass, 22053 sudangrass, PAC F8423 Sorghum can cut mow or hay several times in the area. These varieties can be used as fine varieties in the region, using appropriate ways to promote the use of.
