科学施用化肥,促进了粮、棉、油等农作物大幅度增长;化肥在水域的科学施用,同样可使得渔业获得高产丰收。1986年湖南省临澧县在全国首次用化肥养鱼试验获得成功。1991年,水利部在该县召开了全国水库施肥养鱼会议后,这项技术就在全国由点到面地大面积推广开来,取得了年增产鲜鱼上亿公斤、年获利上亿元的显著效益。化肥养鱼,投入少,产出多,效益大,操作简便。只要正确掌握此项技术,一般2公斤左右化肥就可增产1公斤鱼,每公斤鱼的化肥成本约1元左右。临澧县东堤水库 Scientific application of chemical fertilizers has promoted the substantial increase of grain, cotton, oil and other crops. The scientific application of chemical fertilizers in the waters can also make the fisheries obtain high yield and good harvest. In 1986, Lintao County, Hunan Province, was the first successful trial of fertilizer and fish farming in China. In 1991, the Ministry of Water Resources held a national reservoir fertilization and fish farming conference in the county. The technology was popularized widely from point to area in the whole country. The annual output of fresh fish reached 100 million kilograms, Significant benefits of yuan. Fertilizer fish, less investment, output and more effective, easy to operate. As long as the correct grasp of this technology, generally about 2 kg of fertilizer can increase 1 kg of fish, fertilizer cost per kilogram of fish about 1 yuan. Linqu County East embankment reservoir
