Description

Plant fermentation extract for adjusting fresh water quality and preparation method thereof
Technical Field
The invention relates to the technical field of fresh water purification, in particular to a plant fermentation extract for adjusting the quality of fresh water and a preparation method thereof.
Background
Fresh water is one of water resources, including rivers, lakes, canals, underground water bodies and the like, and only accounts for 2.5 percent of the global water resources, and 87 percent of the fresh water is ice and snow on bipolar ice covers, mountain glaciers and permafrost zones which are difficult to utilize by human beings. The human beings can really utilize a part of the water in rivers, lakes and underground water, and the water only accounts for 0.26 percent of the total water of the geosphere. Furthermore, the distribution of fresh water resources in the world is very uneven, about 65% of the fresh water resources are mainly concentrated in less than 10 countries, and about 80 countries and regions accounting for 40% of the total population of the world are severely lack of water.
At present, only fresh water resources are seriously polluted, and water body pollution mainly comprises pollution of chemical fertilizers and pesticides, pollution of livestock and poultry manure and pollution of rural domestic garbage. A great amount of residual chemical fertilizer and pesticide used for planting crops in rural areas enter ponds, rivers, lakes or seeped into underground water through rain wash and the like, and cause pollution to water bodies.
In recent years, as the desire of farmers for the breeding income increases, the yield and density of aquaculture also increase. On one hand, the excrement of the fishes and shrimps is continuously increased and gradually deposited in the water body, so that the water quality is poor; on the other hand, diseases of the fishes and shrimps are increased in the culture process, the dosage is increased, and the water quality is further deteriorated; thirdly, with the increase of the stocking density, the demand of the stocking density on the feed is correspondingly increased, the amount of the residual bait in the water body is also increased, and the redundant nutrient substances are decomposed and deposited in the water body. The above points cause the increase of ammonia nitrogen, nitrite and hydrogen sulfide in the pond culture water body, the decrease of dissolved oxygen, further cause the increase of fish and shrimp diseases, the dosage increase and the formation of vicious circle.
The current common method is to change water frequently to improve the water body condition, but is not practical in China with increasingly shortage of fresh water resources, especially in the north.
In recent years, microbial preparations are widely applied to aquaculture, but are not ideal in the aspect of solving the water quality of ponds, mainly because the functions of a plurality of floras are respectively long, aerobic type, anaerobic type, facultative type and the like exist, and the microbial preparations are simply fit together and cannot play expected roles.
