本试验从1986年元月开始,至1987年12月17日验收结束,探索了池塘高产的综合性技术措施,解决了大面积连片池塘养鱼高产、稳产的途径。一、参试情况与试验结果: 参试单位共37个,承包专业户共1149户,投入劳力2091个,试验塘1306口、面积11957亩,其中一类塘3768亩,二类塘4556亩,三类塘3633亩。 1、产量:1987年参试成鱼塘11957亩,总产鲜鱼4846.5吨,亩产405公斤,亩净产346.8公斤,其中以草鱼为主的吃食性鱼187.3公斤,以鲢为主的滤食性鱼159.5公斤。比1986年的亩毛产和净产分别增加74.1公斤,65.9公斤,与试验前的1985
The test started from January 1986 to December 17, 1987 acceptance ended, to explore a comprehensive high-yield pond technology measures to solve a large area contiguous pond fish high-yield, stable way. First, the test conditions and test results: a total of 37 participating units, a total of 1149 contracted professional households, labor input 2091, 1306 experimental ponds, an area of 11,957 acres, of which a class of 3768 acres of ponds, 4556 acres of second class ponds, three 3633 acres of ponds. 1, production: 1987 into a trial of 11,957 acres of fish ponds, 4846.5 tons of fresh fish production, 405 kg per mu, net MU yield 346.8 kg, of which grass carp-based fish eater 187.3 kg to silver carp-based filter 159.5 kg of feeding fish. An increase of 74.1 kilograms and 65.9 kilograms, respectively, from the gross and net output of mu in 1986, as compared with 1985 before the test
