化肥养鱼是一项投入小、收益大的养鱼新技术,施用时应注意以下几个问题: 1.施用化肥的水体必须具备的条件是:水流滞缓或无水流;挺水植物少;水温10—12℃以上;气体及PH值等情况良好。以下情况则不宜施用化肥;水库放水前7天及天气闷热无风时;下大雨或雷阵雨刚过之后水质浑浊;鱼出现浮头现象。 2.不同的化肥施用后,水生植物会吸收掉它所需要的离子,从而对池水产生不同的影响,因此对水体施肥前应首先考虑到池水的变化对鱼类的生长是否有
Fertilizer fish is a small investment, the benefits of large fish new technology, the application should pay attention to the following questions: 1. The application of fertilizer water must have the conditions are: stagnant water or no water flow; emergent plants less; Water temperature above 10-12 ℃; gas and PH values are good. The following circumstances should not be the use of chemical fertilizers; reservoir 7 days before the water and the weather was hot and windy; under heavy rain or thunderstorms just after the water turbidity; floating phenomenon appeared fish. 2. Different fertilizer application, aquatic plants will absorb the ions it needs, which have a different impact on the water, so the water before fertilization should first consider the changes in water for fish growth
