1.浮头原因池鱼浮头的主要原因是盲目超量投饵施肥。水质过肥,浮游生物大量繁殖,有机物耗氧量上升和溶氧量下降;自然条件差,放养密度过大,致使水中溶氧不足;池底淤泥过深,水质恶化;长期不加注新水,以致水质肥而老化;水体被污染、含有某种有毒有害物质;久晴不雨,水温过高易致水 1. The reason for the floating head The main reason for the floating fish head is blindly over-fertilization. The over-fertilization of water quality and the plankton multiplication, the increase of oxygen consumption of organic matter and the decrease of dissolved oxygen content, the poor natural conditions and excessive stocking density lead to insufficient dissolved oxygen in the water; the sludge in the bottom of the pond is too deep and water quality deteriorates; , Resulting in fat and aging water; water contaminated with some toxic and hazardous substances; long sunny no rain, water temperature is too high, easy to cause water
