水库种草养鱼与防淤的试验初报

A Preliminary Report on Planting Grasses Around Reservoirs Both As Sources of Fish feed and Preventive Means Against Silt Deposit

为了充分开发利用水库水资源养鱼和减少库内泥砂淤积,保护和改善水库生态环境,作者在库内消落区、荒山堤坝及幼林间人工种植杂交黑麦草、象草、扁穗牛鞭草等鱼用高产优质饲草配套养鱼与防淤进行了试验研究,获得成功。库内鲜鱼产量由种草前常年1000公斤左右提高到7000—8000公斤,泥砂淤积每年减少0.516万立方米。结果表明,采用这一方法对解决库内养鱼长期饵料缺乏,提高库内鱼产量,减少库内泥砂淤积,具有投资少、周期短、效果好的优点。

For the purpose of fully utilization of natural resources and reducing silt deposit,protecting and improving the eco-environment in reservoir areas, high-productivity and top quality grasses such as Loium X Hybidum Hausskn, Pennisetum Purpureum Schumach and Hemarthria were planted on islets,banks,barren hills and among seedling trees in Baibeichong Reservior area. As a result the fish production in the reservior was increased from 1000 kg to 7000 - 8000 kg,silt deposit reduced by 5,160 cubic meters each year. This indicates that with low investment, short periods and good results this method is effective in solving the shortage of fish feed increasing fish yield and reducing silt deposit in reserviors.
