How to sell the EM strain for watering crab ponds?

When purchasing bacterial strains and bacterial liquid for crab breeding, please look for the well-known brand Nongfukang. Bacteria are mainly used in crab cultivation to regulate water quality and sterilize to control the normal growth of algae. Decompose excess organic matter and maintain water quality balance. The composition of the bacteria is a combination of photosynthetic bacteria, nitrifying bacteria and other beneficial bacteria. It has a good solution to problems in aquaculture and is essentially different from drugs without any side effects. It is the new favorite in aquaculture in recent years and has been vigorously promoted by many agricultural bureaus! National ordering hotline: (Manager Sun): (Same as WeChat)

Bacteria are used to regulate water quality:
During the breeding process of river crabs, when the temperature rises every month, the moss begins to die. The water in the pool gradually becomes thicker and muddy, which affects the photosynthesis of aquatic plants. In severe cases, the grass and water will fail. At this time, the entire pond should be sprayed with 1 gram of chlorine dioxide per acre to disinfect the water body, and then the entire pond should be sprayed with the original solution of Nongfukang bacteria, and then poured again every day, so that the beneficial populations in the pond can form an advantage and increase the transparency of the water body. It forms fresh, live, tender and refreshing high-quality breeding water, normalizes the photosynthesis of aquatic plants, improves its ability to purify water quality, and ensures the smooth progress of river crab breeding.
After using the Nongfukang bacterial liquid, river crabs have strong disease resistance, rapid weight gain, large size, good quality, and significant economic benefits. The yield is increased by about 3, and the benefits are improved by ~3. At present, microbial preparations represented by Nongfukang bacterial liquid have been widely used in aquatic crab farming, and have been transformed from the original publicity and promotion period to the active application period by farmers. This is a strong guarantee for the development of ecologically efficient fisheries and is important for the realization of fisheries. Sustainable development is of great significance.

For bait spraying:
In the process of high-yielding and efficient river crab breeding, the daily feeds mainly include fresh small fish, frozen marine fish, pellet feed, etc., especially fresh small fish and frozen marine fish. Contains a large number of bacteria, which can easily cause enteritis in river crabs and pollute the water quality. In breeding, we adjust the feed feeding structure on the one hand, and use Nongfukang bacteria liquid to spray on the other hand. The specific method is: spray Nongfukang bacteria liquid directly onto the bait for feeding, or dilute it with water, seal it and soak it for 3 hours before adding it to the feed. Hello. This can significantly reduce the incidence of crab enteritis and cause less pollution to water bodies.

Use of organic fertilizers:
Common fermentation materials include: various animal manure, grass meal, etc. Organic fertilizer can proliferate beneficial bacteria in large quantities through fermentation, and the fertilizer water promotes the reproduction of zooplankton and avoids pollution of water bodies. It is worth noting that if too much animal manure is used, the dosage per acre should be - kilograms, not too much.
Routine maintenance: It can be splashed every half month or so according to the water quality. One kilogram of bacteria liquid per mu.

The main benefits of cultivating crabs with bacteria:
. Reduce pathogenic microorganisms and undesirable algae, control normal algae and plankton, significantly enhance the immunity and disease resistance of cultured objects, reduce the incidence rate, and improve Survival rate.
.Increase the number of beneficial microorganisms. Zooplankton and beneficial algae are increasing on the water surface, especially red worms, which are increasing to cover the water surface.
3. Stabilize and improve water quality. The water body is fresh in color, not smelly or rotten, and has no odors such as hydrogen sulfide and ammonia. The visibility is long and stable, and the water change time can be extended more than twice.
. Fish and shrimp manure, impurities at the bottom of the pond and scraps will not turn into silt but become loose sand.
.Promote growth and significantly increase weight gain rate. Practice has proved that under the same environment, after using the probiotic stock solution, it can be put on the market in advance, the average yield per mu is increased, the amount of eggs laid is increased, and the egg laying time is extended. Moreover, the hatching rate is good and the bait does not smell bad, which improves the breeding environment.
, Improve the water environment, clean up harmful bacteria in the water, prevent diseases and sterilize.

Precautions for using bacteria:
It is recommended to use it in the evening and afternoon when splashing in the pond.
. Cap the bottle tightly after each use and store it in a sealed container.
It is best to use well water to make probiotic diluent or active liquid. If tap water is used, it should be left for an hour.
Do not mix aquatic bacterial liquid with fungicides, antibiotics and other drugs at the same time. If you use such drugs, you should More than one day apart.
, Store in a cool place, avoid direct sunlight.
Avoid using it at the same time with insecticides and bactericidal drugs.
