稻田养鱼是指利用稻田水面和生物资源,在不改变稻田结构的情况下把种稻和养鱼结合起来的一种立体农业生产方式,但稻田养鱼比起不养鱼的稻田要多消耗一定的水量。近几年来,随着商品经济的发展,稻田养鱼这种能获得较大综合经济效益的生产方式在我省农村得到很大发展,据1986年统计,我省稻田养鱼面积达到27.2万亩。养鱼稻田比起不养鱼稻田究竟要多消耗多少水量,摸清这个数据对水利部门管好水和用好水,充分发挥灌溉水最大经济效益具有一定的现实意义。为此,我所于1986～1987年在黄岩金清气象哨开展了稻田养鱼需水量试验。
Paddy field fish farming refers to the use of paddy water and biological resources, without changing the structure of paddy rice and fish together a three-dimensional agricultural production, but the rice paddy fields than non-fish consumption more fish A certain amount of water. In recent years, with the development of commodity economy, the production of rice farms, which can achieve greater comprehensive economic benefits, has been greatly developed in rural areas of our province. According to the statistics of 1986, the area of paddy fish farming in our province reached 272,000 mu . It is of practical significance for fish farms to consume more water than fish farms that do not raise fish. It is of practical significance to find out this data is of great significance for the water conservancy department to manage water and make good use of water, and give full play to the maximum economic benefits of irrigation water. To this end, in 1986 to 1987, I carried out a test of fish water requirement in paddy fields at the Jingqing meteorological station in Huangyan.
