池塘养鱼时,经常冲注新水,发现能够促进鱼类生长,群众总结为“活水促成长”,而关于“活水促成长”内在规律的研究,目前这项工作做得不多,今年我们选定五个外界条件基本一致的池塘,其中两组试验池,可以分别相互循环注水,而将另一口池塘作对照,进行培育鱼种的试验,两组试验池有明显的增产优势,而对照池远所不及,对有关增产的原因提出我们的看法。 Pond fish farming, often red water injection, found to promote fish growth, the masses summed up as “living water to promote growth”, and on “living water to promote growth,” the inherent law of the study, the current work is not much done, this year we Five ponds with basically the same external conditions were selected. Two groups of test ponds could be recirculated to each other, while another pond was used as a control to test the cultivation of fish species. The two groups of test ponds had obvious advantages in yield increase. However, The pool is far behind and gives our opinion on the reasons for the increase in production.
