潙丰渠灌溉工程,是湖南省1955年度兴建的综合性工程,共灌溉农田115,000市亩,利用渠道跌水修建了一座出力为84瓩的小型农村水电站及3座渠船闸,其中两座系电动操纵。在防治山洪方面,采取了开挖截洪沟的办法,可使约4,000亩农田避免山洪灾,尾闾地区,并开沟建闸,约解决1万亩垸田的渍灾。工程完成以后,对农业增产起了很大的作用,仅灌溉效益一项,1956年就为国家增产粮食达1,800万斤,折合人民币99万元,兴建费用一年即可收回。
Feng Feng drainage irrigation project, Hunan Province in 1955 to build a comprehensive project, a total of 115,000 acres of farmland irrigated, the use of channel water to build a small power station output of 84 农 rural hydropower station and three canal locks, two of which are electric manipulate. In the prevention and treatment of mountain torrents, we adopted a method of excavating flood interception ditch to avoid about 4,000 hectares of farmland from mountain torrents, tailings areas, and ditching gates, so as to solve about 1 million mu landlocked droughts. After the completion of the project, it has played a significant role in boosting agricultural production. Only one irrigation benefit has been achieved. In 1956, the country increased its output of grain by 18 million kg, equivalent to RMB990,000, and the construction cost could be recovered in one year.
