摘要
洞庭湖区拥有丰富的芦苇和荻资源。两者鲜嫩时的化学与营养成分接近优良牧草黑麦草，适于饲喂牛。若于拨节中期收获２～４次，则可年产干草４．５～７．５×１０５ｔ，可为８．２２～２０．５５×１０４个黄牛单位提供全年用优质饲草；若再与湖区丰富的农副产品相配合，发展集约化商品性的养牛业是切实可行的。收获的牧草可通过青饲、青贮、调制干草、加工成草粉或颗粒配方饲料的方式加以利用。为保障秋季其他用途的收获及第二年的正常生长发育，必须要采取一系列行之有效的措施，其中人工促进再生复壮和加强宏观调控是最关键的环节。
The region of Dongting Lake is rich in reed Phragmites communis and its kindred Miscanthus sacchariflorus.When green and tender,they have chemical and nutrient composition similar to Lolium perenne,which is a superb fodder for cattle.If they are harvested 2～4 times in the middle period of jointing,4.5×10 5～7.5×10 5 t dry grass can be obtained,which can supply high quality forage grass for 8.22×10 4～20.55×10 4 Yellow Cattle Unit (YCU) annually;when combined with abundant agricultural products and their by products,it is completely possible for this region to establish and develop intensive,commercial cattle husbandry industry.The harvested grass can be utilized by direct feeding,silaging,making dry geeen grass by desiccation,processing grass powder and producing granular formulated feeds.In order to guarantee harvest for other aims in Autumn and normal growth and recovery in next year,it is quite necessary to take some effective measures among which the two key ones are artificially promoting regrowth and recovery as well as the strengthening of macro scale management.
