Bio-organic fertilizer mechanism and effect
In recent years, the environment of freshwater aquaculture in China has been deteriorating, resulting in frequent occurrence of various diseases. In order to control diseases, the abuse of various antibiotics has directly led to serious imbalances in the living environment of animals and plants in water, and the quality of aquatic products is getting worse. . In the face of this state of aquaculture, bio-fertilizers that meet the needs of human health have emerged.
The use of probiotics (good microorganisms or beneficial bacteria) to regulate water quality has two major functions; the first is to improve water quality. After the beneficial bacteria in the microecological preparations enter the water body, they exert their functions such as oxidation, ammoniation, denitrification, phosphorus release, sulfidation, and nitrogen fixation, rapidly decomposing organic substances such as excrement, residual feed, and animal remains of the farm animals, effectively reducing the body of water. Ammonia nitrogen and nitrite concentrations; salts of organic decomposition provide a good ecological environment for the growth and reproduction of unicellular algae. The second is prevention. The beneficial bacteria of the microecological preparations are applied in the aquaculture water, which not only competes for rejection of pathogenic bacteria, maintains the ecological balance of the microecological flora in the water, prevents aquatic organisms from being attacked by pathogenic bacteria, but also produces antibacterial substances and various The immune-promoting factor activates the body's immune system, strengthens the body's anti-reaction response, enhances resistance to disease, and improves survival.
The so-called biological fertilizer is a kind of efficient new compound fertilizer containing beneficial microorganisms. The special biological fertilizers for aquaculture are generally composed of organic matter and inorganic nutrients, trace elements, beneficial bacteria and biotin, and fertilizer synergists. It not only can fertilize water quality, promote the growth of fish, shrimp, and crab food organisms, but also improve water quality, reduce disease, effectively avoid flooding ponds, and promote the rapid growth of fish, shrimp, and crab. The relevant experiments and use prove that the use of biological Fertilizer cultivation, its cost is lower than the traditional carbon ammonia, phosphate fertilizer, but the breeding effect is significantly better than the traditional carbon ammonia, phosphate fertilizer breeding mode.
The application of bio-fertilizer in freshwater aquaculture has four advantages: First, the fertilizer and water are fast and the fertilizer has lasting effect. If it is used on a sunny morning, the water color will change on the second day, and the normal effect of fertilizer can last for about 10 days. The color of fertilized water is mainly yellow-green to yellow-brown in food organisms with high nutritive value such as silicon, naked, cryptic, golden algae and rotifer, and it is not distinct from the dark green and blue-green water color of traditional fertilizers. Second, it can adjust the water quality and improve the quality of the bottom. The trace elements contained in biological fertilizers are not only used directly by aquatic organisms, but also combined with certain poisonous and harmful substances in water bodies to relieve their toxicity and reduce the toxicity to farmed fish, shrimps and crabs. At the same time, through the role of beneficial microorganisms in fertilizers, it can reduce suspended solids in water bodies and degrade ammonia nitrogen, ammonia sulfide, and nitrite, and it also has a good effect on regulating water quality and improving sediment quality. Third, it can increase dissolved oxygen and reduce floating heads and pans.
In addition to the ability to regulate water quality and increase dissolved oxygen, biotin in bio-fertilizers can increase the metabolism of algae, increase the efficiency of photosynthesis, synthesize more organic matter and produce oxygen, and effectively avoid hypoxia. Finally, it can improve the immunity of aquaculture animals and achieve the goal of disease prevention. The production process of biological fertilizers generally requires microbial solid-state fermentation, and the pathogenic bacteria in the fertilizers can be effectively suppressed. The trace elements contained in the fertilizers can improve the physiological function of aquatic animals, increase their immunity, and enhance disease resistance. At the same time, the improvement of the water environment and the increase of dissolved oxygen in water can also reduce the occurrence of diseases.
The use of biological fertilizers containing large amounts of microorganisms in aquaculture requires special attention to three points: First, it is necessary to pay attention to whether the aquaculture water environment is suitable for the survival and reproduction of beneficial bacteria, if disinfectants, antibiotics or use are used together with biological fertilizers. The short interval time will reduce the application effect of biological fertilizers, and the use time of the two should generally be separated by at least 5 days. Secondly, the activation and reproduction of beneficial bacteria require oxygen consumption. Therefore, it is best to apply supplemental oxygen in sunny days or after application, so that it can exert ideal effects. Finally, the beneficial bacteria should be formed as soon as possible and be durable. Therefore, the number of live bacteria contained in the fertilizer must reach a certain target. The amount of viable bacteria used after the first use and exchange of water should be sufficient, and the long-term use of the bacteria should be maintained. .
I. The main mechanism of action of "Dongyi" bioorganic fertilizer
"Dongyi" bio-organic fertilizer combines three functions into one, and the main mechanism is as follows:
(1) Grazing food chain (inorganic fertilizer): The directional culture of food organisms (algae) with high nutritional value is for white pelagic and zooplankton; the zooplankton can also be used as opening food for most fry and natural for calyx. Food.
(2)Organic chopped food chain (organic fertilizer): The organic debris formed by organic materials with high bait value is used to directly cultivate heterotrophic bacteria and zooplankton, and flowers and omnivorous fish can also be eaten directly.
(3) Probiotics and their secretions (fertilizer): Inorganic fertilizers and organic fertilizers are integrated to increase the utilization of fertilizers; beneficial bacteria and their physiologically active substances produced by fermentation improve water quality, inhibit disease, and improve fish body. The effect of growth speed is remarkable.
Second, the main effect
"Dongyi" bio-organic fertilizer has significant effects in the following four aspects:
(1) Improve water quality and improve the environment
"Dongyi" bio-organic fertilizer is rich in photosynthetic bacteria, Bacillus and other beneficial bacteria. After being applied to water, it can accelerate the transformation of organic matter and mineral nutrients on the one hand, and acts as a "scavenger" on the other. Decomposition and elimination of harmful substances can effectively degrade harmful substances such as nitrites and ammonia nitrogen in water bodies, increase the amount of dissolved oxygen in water bodies, improve the water quality, make the aquaculture water bodies clear and moderately transparent, and comply with national regulations on aquaculture. Water standard.
(2) Speed ​​up the reproduction of plankton and the growth of flower buds in water bodies
Plankton growth and reproduction requires not only nitrogen, phosphorus, potassium, and organic matter, but also moderate amounts of trace elements. The single application of chemical fertilizer can not meet its needs. "Dongyi" and "Dongyi" biological organic fertilizer integrates inorganic fertilizer, organic fertilizer and biological bacterial fertilizer, which can not only satisfy a large number of elements needed for the growth of plankton, but also provide abundant The organic matter and trace elements can promote its rapid reproduction and provide abundant food for the growth of fish so as to achieve rapid growth.
(3) Reduce the disease and improve the quality of aquatic products
"Dongyi" bioorganic fertilizer is not only reflected in the improvement of water quality but also in the prevention of fish diseases because of its unique biological characteristics.
It also shows a unique effect. A variety of beneficial bacteria multiply in water, effectively inhibit the reproduction of harmful bacteria, enhance the immune function of fish, and have better preventive effects on some bacterial common fish diseases. The use of this fertilizer for a long period of time can reduce the incidence of 60-70% for the production of bacterial septicaemia, the most dangerous form of bacterial sepsis, and play an important role in improving the quality of aquatic products.
(4) Cost-effective bait, high overall benefit
"Dongyi" bio-organic fertilizer in addition to the supply of water plankton nutrients, which formed a large number of beneficial bacteria aggregate itself is a high-protein food for filter-feeding fish. In addition, various enzymes produced by beneficial bacteria can reduce the feed coefficient, synthesize vitamins B, K, amino acids and some unknown factors to participate in metabolism, thereby promoting the growth of various fish species. At the same time, the organic materials after fermentation can replace some of the foods such as grass carp, squid, and squid that feed on fish. This has a very practical significance for improving the comprehensive benefits of hybrid stocking mode.
Third, improve fish productivity and fishery comprehensive operating efficiency
(1) can raise high-quality varieties. Since “Dongyi†and “Dongyi†bio-organic fertilizers have good restoration and maintenance performance for good water quality, it is possible to select those species with good quality and higher water quality, such as grass carp, catfish, and bonito (traditional culture). The water quality is poor and there are many diseases in the model. These fish are often not effective. These varieties are more liked by consumers. The prices are better and they are easier to sell, making the fish ponds faster and more efficient; and breeding these high-quality varieties is also Can get higher benefits.
(2) Higher yields of the same species in culture. Due to the use of "Dongyi" bio-organic fertilizer, which can be used as a fertilizer and can maintain good water quality, the stocking density can be appropriately increased to increase the yield and increase the growth rate. The beneficial bacteria polymer itself contains a large amount of enzymes and vitamin B family. The K group, amino acids, etc., which are eaten by fish, can improve the intestinal environment of the fish, help digestion, and increase the utilization of feed.
(3) Improve product quality is conducive to the formation of a brand. Due to the "Dongyi" bioorganic fertilizer's improving effect on the aquaculture water environment, the quality of fish cultured products meets the pollution-free standard, and deep processing can be carried out, thereby prolonging the industrial chain and obtaining higher processing profits, while deep processing of fish products. The development can also promote the scale and production of breeding, so that mutual promotion can create a brand of fishery, and the creation of a brand can bring more reliable and richer profits for the farming business.
