在中、小型水库施化肥养鱼,有许多技术问题急待我们探讨解决。我们于1984年在本县的中型水库进行试搞,取得了较好的效果,单产从几公斤提高到25公斤。在试搞过程中,我们对施用化肥的种类、方法、施化肥后水质的变化和不清箱搞网箱育种的可能性等问题进行研究,现将粗浅意见,简述如下。一、关于施用氯化铵的问题 In medium and small reservoirs of chemical fertilizers fish, there are many technical problems urgently we explore to solve. In 1984, we tried out the medium-sized reservoirs in this county and achieved good results, with yields ranging from a few kilos to 25 kilos. In the trial process, we applied fertilizer types, methods, changes in water quality after fertilizer application and do not know the possibility of cages breeding cage research, the superficial views are summarized as follows. First, on the issue of the use of ammonium chloride
