摘要
在高温季节,对高密度养殖池塘每10 d泼洒1次EM复合菌,施用量为每次600 g/(667 m2.m),使用后试验池水体中的氨氮、亚硝酸盐等有害物质及总磷、总氮含量显著下降,溶氧量增加。水质改善后,鱼类的体质增强、发病率下降,水质调控效果较显著。经测算,试验池养殖成本降低354.0元/667 m2,鱼病发生率降低32.2%,增产28.0 kg/667m2,7-9月平均节水1 036 t/667 m2。
In high season for high density of culture to spray the virus every 10 d a time,the application was 600 g/（667 m^2.m）,after using the body of the ammonia ikemizu nitrite harmful substances such as nitrogen,phosphate and the total,nitrogen content,oxygen melting down significantly increase the quality and species improvement.After the health of the increase,rates,water quality control was a significant effect.It is estimated that the culture of 354 Yuan/ 667 m^2 cost,the fish was to reduce the incidence of 32.2%,yield added 28.0 kg/667 m^2,Jul.to sept.saved 1 036 t/667 m^2.
