摘要: 开展芦苇资源化利用及饲用研究,对于合理开发利用本地化饲料资源、增加本地的畜禽生产能力、解决反刍动物饲料缺口问题和发展养殖业具有重要意义。为探索不同生育期芦苇农艺性状、产量及营养成分变化,分析确定以鲜芦苇草作为青贮原料的最佳收获时间,开展了本试验研究。结果表明,生长后期至孕穗期的芦苇生长旺盛,产量明显上升,新鲜的青绿叶片较多,且各类养分含量均衡。因此,建议刈割七月初至八月上旬生长后期至孕穗期的芦苇作为饲料原料进行青贮加工调制,芦苇刈割时的留茬高度>4 cm。本研究结果为芦苇的饲料利用方式及发展节粮型畜牧业提供了有效的技术支撑。

Abstract: Conducting research on the resource utilization and feeding of reeds is of great significance for the rational development and utilization of localized feed resources, increasing local livestock and poultry production capacity, solving the problem of feed shortage for ruminant animals, and developing the breeding industry. To explore the changes in agronomic traits, yield, and nutritional composition of reeds at different growth stages, and to analyze and determine the optimal harvesting time using fresh reed grass as silage material, this experimental study was conducted. The results showed that the growth of reeds from the late growth stage to the booting stage was vigorous, with a significant increase in yield. There were more fresh green leaves and balanced various nutrient contents. Therefore, it is recommended to cut reeds from early July to early August, that is from the late growth stage to the booting stage, as feed materials for silage processing and modulation. The stubble height during reed cutting should be greater than 4 cm. At the same time, it is recommended to further carry out research on the processing and utilization technology of reed feed, so as to provide effective technical support for the utilization of reed feed and the development of grain saving animal husbandry.
