实行稻田养鱼,可获得较高的经济效益,如技术措施不当,则往往收效不大,这也是稻田养鱼难以推广的重要原因之一。为摸索稻田养鱼的技术措施,夺取稻田养鱼最佳的经济效益,我们设计了宽沟窄垄免耕半旱田,开展了垄上种稻,沟里养鱼的试验。1983—1984年的试验结果表明,垄种稻、沟养鱼的气象效应明显,经济效益显著。专家们鉴定认为,这是改造低产田,实现稻田产值翻番的一项新技术。 Implementation of paddy field fish farming, access to higher economic benefits, such as improper technical measures, it is often ineffective, which is difficult to promote rice farming one of the important reasons. In order to explore the technical measures for fish farming in paddy fields and to seize the best economic benefits from paddy field fish farming, we designed a semi-dry land with wide-ridge narrow ridge and no-tillage furrow and conducted experiments on the cultivation of rice and furrows in the ridge. The test results from 1983 to 1984 showed that the meteorological effects of furrowed rice and furrowed fish were obvious and the economic benefits were remarkable. Experts believe that this is a transformation of low-yield fields, rice production to double the output of a new technology.
