Background

The water body plays a vital role in agricultural development, not only can be used as a water supply foundation for farmlands and planting fields, but also can be used as an important carrier for aquatic landscape animals and plants and cultivation of the animals and the plants. However, as urban construction steps are accelerated, the agricultural land and water use range is gradually reduced, and the water quality is continuously influenced by environmental changes. According to the quality standard of surface water environment (GB3838-2002), five types of water are mainly suitable for agricultural water areas and water areas with general landscape requirements, and three types of water are mainly suitable for fishery water areas such as aquaculture areas. With the acceleration of social development and the continuous increase of population base, the environmental pollution problem becomes more and more prominent, and the problems of air pollution, industrial discharge and the like are solved, so that the water quality is difficult to maintain on the basis of the composite water use standard, a plurality of water bodies originally used as landscapes and aquaculture can not reach the three standards, even the integral water quality of a plurality of water bodies is reduced to the fifth standard, and the functionality of the water bodies is seriously influenced.

The water quality of the water body is reduced, and the water body is polluted by the environment, so that the ecological environment in the water body is damaged, harmful microorganisms are bred in a large quantity, toxic substances are accumulated in a large quantity, the dissolved oxygen content of the water body is greatly reduced, the light transmittance of the water body is continuously reduced, and finally, the phenomena of turbidity, blackness and odor of the water body are caused, and a large amount of death of animals and plants in the water body is brought.

Therefore, if a novel modifying agent formula which can be used in landscape/aquaculture water bodies can be obtained, a green modifying agent which is based on natural substances and microorganisms is manufactured, components in the modifying agent are directly added into the object water body and are skillfully combined into the traditional physical or biological process, natural and organic properties are realized, chemical and artificial synthesis technologies are not needed, the effects of quick effect, long effect and slow release are simultaneously met, after the modifying agent is added into the water body, the ecological system of the water body can be recovered, the phenomena of turbidity, black and odor are eliminated, and the modifying agent plays an important promoting role in the field of ecological restoration of the current landscape/aquaculture water bodies.

the modifier is prepared by physical mixing, extrusion forming, drying and dehydration (40-60 ℃), has no chemical synthesis step in the process, does not produce discharge of pollutants such as waste water, waste residue, waste gas and the like, and does not cause environmental pollution. The product can be used in any state and stage of the water body, and can generate the effect without adding at a specific time node. The core elements in the formula consist of preferred minerals, compound microorganisms and organic matters:

(1) the preferred mineral in the formula contains medium and trace elements which are mined from natural deposited organic rock and mineral components, so that the mineral can be quickly integrated into the water environment and can be directly utilized by environmental ecological microorganisms, animals and plants. After being mixed in a certain proportion, elements such as boron, manganese, zinc, molybdenum, iron, selenium and the like play a very important role in the metabolism of microorganisms, the growth and development of aquatic animals and plants. And the mineral substances formed by screening and proportioning combination have abundant types and contents of trace elements, can adapt to the water quality requirements of various conditions, and can supplement the trace elements lacking in the water body.

(2) The microbial flora contained in the formula is a preferred strain subjected to directional screening, has high activity and quick response, can quickly enter a logarithmic phase for mass propagation after entering the environment, quickly dominates in competition with harmful microorganisms (pathogenic bacteria) and the like, inhibits the growth of plant diseases and insect pests, for example, bacillus has biological activities of dissolving phosphorus, dissolving potassium, fixing nitrogen and the like, is favorable for improving the crop yield, and antibacterial substances generated by the bacteria can prevent and treat various plant diseases. Microorganisms enter the environment and begin to rapidly utilize the metabolism of surrounding substances to produce natural inorganic salts, organic matters, amino acids, saccharides and the like required by plant growth.

(3) The nutrient organic matter contained in the formula contains a large amount of naturally fermented medium elements, is rich in content, is easy to decompose and absorb after pretreatment and fermentation, and supplements nutrients for rapid growth and metabolism of microorganisms and nutrient absorption of animals and plants in the ecological environment.

(4) The modifier is prepared from three core materials, namely fine inorganic particles, kaolin and bentonite which are popular in the market are continuously used in the selection of auxiliary materials, and the inorganic materials are taken from the natural environment, have good biocompatibility and certain adhesion degree, can provide a large amount of porosity and become the best partner of a modifier product.

The modifier prepared by the invention belongs to a natural organic product, has mild properties, a pH value of about 6-8, has water body microorganisms and all large, medium and trace elements required by growth of animals and plants, has a trace element ratio higher than that of the modifier commonly used for water bodies, takes effect quickly, has the shortest effective period of 1 week and lasting effect, and can slowly release nutrient components for 3 months at most after single addition:

(1) the modifier has quick effect, can improve the water condition after being put into use for 1 week, and in a part of implementation cases, the modifier is put into use in the middle of agricultural activities or achievement links, so that the landscape/aquaculture water environment is improved obviously in the shortest 1 month period. Therefore, the system can be immediately put into use at any stage of the landscape/water body culture activity, and has an effect.

(2) The modifier series products have long-acting slow release function. Auxiliary material particles (kaolin, bentonite, sodium carboxymethylcellulose and the like) contained in the modifier formula provide certain adhesiveness and internal porous space, slow release of other minerals and other components is increased, the modifier is effective for a long time, and the timeliness in water can reach 3 years to the maximum.
