Water temperature rose to above 20 ℃, fish consumption, rapid growth, fertilization to a small amount of times, look at water fertilization, Qin facilities top dressing. Summer high water temperature, avoid excessive fertilization, to avoid a drastic decline in water oxygen capacity, water quality deterioration, Pan Tong occurred. The amount of bait fertilizer in summer and autumn can account for about 70% of the total amount of the whole year. Winter water should also be fat
