| 摘 要： | 从日本引进饲用高粱（Sorghum bicolor）种子，在甘肃省榆中县进行了夏播试验，对其生物学特性及适应性进行观测，并对其生长120 d后的草产量及牧草营养成分进行分析。结果表明，日本饲用高粱具有抗旱、抗寒、生长茂盛的优点，能适应榆中县的气候、土质、水肥条件；农田生长120 d后，鲜草产量达184.50 t·hm-2，干物质产量达43.46 t·hm-2，高于本地普通高梁成熟期产量。其全株主要营养成分与本地成熟期收获的普通高粱接近，总能约为本地高粱的2倍；与在日本种植至成熟期收获的全株营养成分相比，粗蛋白含量高59.91%，无氮浸出物含量高15.91%，粗纤维含量低20.14%，粗脂肪含量低72.52%。总体分析,日本饲用高梁是一种适应性强、产量高、营养价值高的饲料作物,适合在榆中县种植。

| Abstract: | Forage Sorghum(Sorghum bicolor)seeds was introduced from Japan.Summer sowing test was conducted to observe its biological characteristics and local adaptive in Yuzhong County in Gansu province,and the grass yield and forage nutrients was analyzed after 120 days growth period.The results showed that,Japan forage sorghum have the advantages of cold and drought resistance and flourishes,and it’s adapted to the climate,soil and water fertilizer conditions of Yuzhong county.After 120 growing days,fresh yield and dry matter yield were 184 500 kg·ha-1 and 43 460 kg·ha-1,respectively,which is higher than that of local sorghum at the mature period.Main nutritional components(dry matter) of the whole plant of Japan forage sorghum were similar to those of local sorghum at the mature period,but,gross energy is about twice as much as local sorghum.Comparing with the whole plant of Japan forage sorghum that harvested at the mature period in Japan,when growing in Yuzhong county,the crude protein and nitrogen-free extract content were enhanced by 59.91% and 15.91%,and the crude fibre and ether extract were decreased by 20.14% and 72.52%,respectively.Overall,Japan forage sorghum is a good forage crop with excellent adaptability,high yield and high nutritional value,which is suitable for planting in Yuzhong county. |
