为了筛选出适宜黑龙江地区种植的优质饲用高粱品种,试验在高粱孕穗期、开花期和成熟期收割,测定了饲用高粱的株高、茎粗、鲜草产量、干鲜比和干草产量。结果表明:不同饲用高粱品种生育进程存在明显差异,其中Ms1990、海牛、超卡、F10、3701、As6021、健宝、绿巨人不能够正常抽穗开花,在当地不能成熟。对饲用高粱鲜草产量进行测定,鲜草产量以Ms1990最高,为962 80.42 kg/hm~2;帕卡鲜草产量最低,为433 53.17 kg/hm~2。高粱品种干草产量从高到低依次为3701>Ms1990>As6021>F10>健宝>As6017>绿巨人>6022>海牛>As6013>YCS>超卡>BT>绝佳>龙甜1号>牛魔王>6015>6023>帕卡。
In order to select suitable high-quality sorghum varieties for planting in Heilongjiang Province, the experiment was harvested at the booting, flowering and maturing stages of sorghum. The plant height, stem diameter, fresh grass yield, dry fresh ratio and hay yield of sorghum were measured. The results showed that there were significant differences in the growth of different sorghum forage species. Among them, Ms1990, manatee, super-card, F10,3701, As6021, Jianbao and Huligi could not normally flowering and heading, and could not mature locally. Fresh sorghum yield of fresh sorghum was measured, with the highest fresh yield of Ms1990, which was 962 80.42 kg / hm ~ 2. The lowest fresh yield of Paka was 433 53.17 kg / hm ~ 2. Sorghum varieties hay production in descending order of 3701> Ms1990> As6021> F10> Jianbao> As6017> Hulk> 6022> Manatee> As6013> YCS> Super> BT> Superb> 6015> 6023> Packard.
