Fish pond water clear can be combined with bio - fertilizer compound do
Base fertilizer generally use animal manure and other organic fertilizers, green fertilizer can also be applied to the general per acre can be 150-250 kg of manure, or green fertilizer 100-150 kg. The new pond, the new clear pond, thin pond, wheel rounds of round pond and silver carp, bighead carp-based fish ponds, should be based on the actual situation, the appropriate increase in fertilizer. Fertilizer ponds can be less or not applied. The other is the top dressing. In the lack of feeding, base fertilizer and fish excrement can not meet the needs of natural food biological reproduction, water quality gradually thinner, slow growth of fish in the case, should be timely application of top dressing. Shi top of the fertilizer should be less times, even sprinkle sprinkle, to see the water fertilization, to master the amount of fertilizer and the number of times to control water quality changes. Fertilizer can be less or not applied, light water should be timely dressing, too thick water should also be appropriate to add new water to prevent water quality deterioration.
Fish ponds can be used bio-fertilizer compound fertilizer, fish pond fertilization is to promote water quality fertilizer, increase the pool of nutrients, cultivate a large number of natural fish bait, to make up for the lack of food and take an effective measure. Fertilizers are mainly animal manure, manure, green manure and fertilizer. Fertilization methods are two: one is the base fertilizer. Base fertilizer should be early, Shi foot, so you can breed as soon as possible natural food. At the same time after the pool of fat, but also easy to absorb light and heat, improve water temperature, the corresponding extension of fish growth period.
Fertilization should also be based on weather and fish activities. When the weather is hot, low pressure, or when the next mine do not fertilize; when the fish in the morning when the phenomenon of floating head or fish disease, do not fertilize. Only in good weather, fish activity is normal, water quality is really thin case, it should be fertilizers. In addition, it should also pay attention to manure, animal manure to go through the fermentation before they can be applied to the pool; fertilization to avoid the fish food field, and fertilizer to mix after the whole pool sprinkle.
