鱼塘不仅要下鱼食,也要施肥。几条忌讳要注意:一忌雨天施肥,雨天水体浮游植物光合作用弱,氮、磷吸收差,而水量增加使肥的浓度降低,溢洪时肥料流失。二忌闷热天施肥,此时水中溶氧低,有机物耗氧增加,易造成鱼类缺氧而浮头泛塘。三忌浑水施肥,水浑浊时肥料的部分离子易被黏土粒子吸附沉淀,肥效
Fish ponds not only need to fish food, but also fertilize. A few taboo should pay attention to: Avoid rainy days fertilization, rainy days Phytoplankton photosynthesis is weak, poor absorption of nitrogen and phosphorus, and the increase in water to reduce the concentration of fertilizer, spill loss of fertilizer. Second bogey sultry day fertilization, when low dissolved oxygen in water, oxygen consumption of organic matter increases, easily lead to fish lack of oxygen floating Pan Tong. Three bogey muddy water fertilization, water turbidity when some of the fertilizer particles easily adsorbed by precipitation, fertilizer
