一、浮头原因 1、上、下水层温差较大,产生急剧对流(多在盛夏时期傍晚下雷阵雨后出现)而引起的浮头与泛池。 2、光照不足,浮游植物光合作用弱,溶氧供不应求。多发生在夏季连绵阴雨或大雾天气里。 3、因水质过肥或败坏而引起浮头。夏季久晴不雨,池水温度高,加上大量投饵施肥,有机质过高,耗氧大。又长期未加注新水而引起浮头。 二、预测方法 1、看天气:如果夏季傍晚下雷阵雨,第二天可能浮头;久晴无雨,鱼类摄食旺盛,水质过肥,一旦天气变化易浮头;阴雨连绵易浮头。
First, the floating head causes 1, the temperature difference between the upper and lower aquifers, resulting in rapid convection (mostly in the evening after the thunderstorm thunderstorms appear) caused by the floating head and pan pool. 2, lack of illumination, phytoplankton photosynthesis is weak, dissolved oxygen in short supply. Occurred in the summer rainy or foggy weather. 3, due to excessive water quality or corruption caused by floating head. Long sunny summer does not rain, the water temperature is high, coupled with a large number of feeding fertilization, organic matter is too high, oxygen consumption. Long-term did not raise new water caused by floating head. Second, the forecast method 1, to see the weather: If the summer evening thunderstorms, the next day may be floating head; long sunny no rain, strong fish consumption, water quality is too fat, easy to float once the weather changes;
