水利是农业的命脉。农作物若是及时适量浇上水就能大幅度地增产;若是被水淹没三日以上就会严重减产,甚至颗粒不收。排灌机械是战胜早涝灾害,做到遇旱灌水,遇涝排水,确保农业高产稳产的灌溉或排涝的机械设备。我国排灌机械事业,解放后从无到有,从小到大,从半机械化到机械化,特别是无产阶级文化大革命以来发展很快。旱涝两用的江都水利枢纽工程,每昼夜可排水一千万吨,或提水灌溉稻田一百二十六万亩。大大小小各式各样排灌站遍布全国各地,使用的能源有热能、电能、水能和风能等,对农业旱涝保收起了极为重要作用。
Water conservancy is the lifeblood of agriculture. If the crop timely and proper amount of water can greatly increase production; if it is flooded for more than three days will be a serious cut, and even the particles do not accept. Drainage and irrigation machinery is to overcome the floods and early floods, drought case of irrigation, waterlogging drainage, to ensure high-yield stable agricultural irrigation or drainage machinery and equipment. The cause of irrigation and drainage machinery in our country has grown rapidly from scratch to infancy and from semi-mechanization to mechanization, especially after the Great Proletarian Cultural Revolution. Drought and flood use of the Jiangdu water control project, every day and night can drain 10 million tons, or raise irrigation water 1.2 million mu of paddy fields. Large and small A wide range of irrigation and drainage stations throughout the country, the use of energy with heat, electricity, water and wind energy, agricultural drought and flood protection has played an extremely important role.
