摘要
以两个葛品种(湘葛1号、湘葛2号)为材料,比较不同收获方式下(年收获一次和年收获两次)葛茎叶饲用产量和营养品质的差异。结果表明:不同收获方式下,地上部分粗蛋白含量最高的为湘葛2号两次收获,其粗蛋白含量达15.89%;湘葛2号两次收获地上部分的干产量和粗蛋白产量均表现较好,分别为18 476.85 kg/hm2和2 935.97 kg/hm2。葛地上部分可以作为一种良好的饲料资源加以利用。
The differences of forage yield and nutritional about aboveground part of the two species of Pueraria lobata （ Xiang ge I and Xiang ge 2 ） with different harvestings （ harvest by once and twice per year） were compared. The results showed that, the aboveground part of Xiang ge 2 harvest twice per year had the highest crude protein content, which reached 15.89%. And the dry yield and crude protein yield of the aboveground part of Xiang ge 2 harvest twice per year were the best, which were 18 476. 85 kg/hm2 and 2 935.97 kg/hm2 respectively. The aboveground part of Pueraria lobata could be used as a kind of good feed resources.
