Sodium humate is made of low-grade coal containing humic acid as raw material, obtained with caustic soda solution, then settled to remove ballast, extracted and dried, and it is a bright black powder crystal.

Sodium humate, which is common in aquatic products, originally had these three disadvantages

The main uses of sodium humate are very common. In recent years, many biological product companies have carried out scientific research on the development and design of sodium humate, and it has also been widely used in the aquatic product aquaculture industry.

According to the performance and research of the farm, the (granule) commodity with sodium humate as the raw material has 3 advantages:

First, it has the effect of inhibiting the growth and development of green moss

2. It has the effect of purifying water by coagulating and coagulating in the water body.

3 is a fertilizer synergist

The actual effect of EM bacteria in aquatic product aquaculture is generally recognized. However, the application of good source liquid of EM bacteria is relatively expensive, and after long-term storage by manufacturers and agents, the charm of bacteria will be reduced. In recent years In the sales market, EM strains are warmly welcomed by farms. The farms can expand their cultures after purchasing them. The EM strains that produce alcohol by themselves are inexpensive to apply, and it is found that the total number of strains produced by alcohol is large. The specificity is good. Then in the case of selecting EM bacteria, everyone should pay attention to the pros and cons of the strain. Generally speaking, there is a very simple index value pH value to distinguish the pros and cons of the strain. Because the lactic acid bacteria beverage of the EM strain The highest content, the lower pH value of the EM bacteria solution indicates that the lactic acid bacteria beverage has rich and colorful content, which means that the overall EM bacteria specificity is higher. Generally speaking, the pH value below 3.5 is considered a good bacteria species. EM strains below 3 are considered to be of particularly good quality.

However, the shortage of sodium humate in aquaculture is also very large.

First, after use (granules), all the water bodies turn black for 5 to 10 days, resulting in no sunlight, no plant photosynthesis, and bacteria and algae cannot grow and develop;

2. Sodium humate has a high adhesion and coagulation effect, and the heavy metals in the water body exceed the standard, and the sulfate and toxic substances agglomerate in the foundation settlement pool, which cannot be dissolved. It is not allowed to disintegrate normally, such as repeated use of sodium humate for many times, there will be rotten roots, and the roots will fall to the ground;

3. The lack of plant photosynthesis in the water body, the imbalance of bacteria and algae phase, resulting in the reduction of dissolved oxygen in the pond, the difficulty in turning the hairy crabs over, and the situation that the molting is not chasing, and the multiple of turning over the shells is also small.

At this stage, there are various types of oxygen-enhancing products on the market. Traditional oxygen-enhancing products are restricted by technology and secret recipes, and they generally release oxygen in a centralized manner for 3-8 hours. Such centralized oxygen-releasing products quickly release oxygen in a short period of time. , CO2 is very easy to quickly overflow the water body, the actual effect of pond retention is poor, and it is very stimulating to the breeding animals. In addition, the application cost increases, and manpower must always pay attention to the oxygenation status. The brand-new technology is the use of excellent retardation technology and unique secret recipe. , so that CO2 can be slowly released in the pool, and the actual effect of oxygenation can last for more than 30 hours. Such oxygenation products are low-cost, and the oxygen release time is long and continuous, saving time, convenience and effort.

The farm should use sodium humate with caution, and it should not be reused many times.

Even if it is absolutely necessary, the first thing to look at is the content, which is generally within 5℅. If the product is not marked with its ingredients and content, it is strictly prohibited to use it;

The second is to use sodium humate products with low content of particulate matter to ensure that the water body will not change black, and will not harm sunlight exposure and plant photosynthesis.
