Fresh water polyculture fish compound biological pesticide fertilizer and preparation method thereof

Abstract

The invention discloses a fresh water polyculture fish compound biological pesticide fertilizer and a preparation method thereof. A formula of the fresh waterpolyculture fish compound biological pesticide fertilizer consists of the following components in parts by weight: 50-60 parts of chicken manure, 20-25 parts of acidolysis residues, 10-15 parts of straw powder, 8-10 parts of egg shell powder, 0.1-0.2 part of bacillus subtilis, 0.1-0.2 part of aspergillus oryzae, 0.1-0.2 part of brewer's yeast, 8-10 parts of celastrus orbiculatus, 3-4 parts of azadirachta indica, 4-6 parts of monkshood, 3-5 parts of coptidis rhizome, 2-4 parts of copper sulfate, 12-14 parts of potassium sulfate, 12-14 parts of ammonium bicarbonate, 10-15 parts of calcium superphosphate and 12-14 parts of urea. According to the fresh water polyculture fish compound biological pesticide fertilizer, fermented organic substances and inorganic fertilizer are mixed, and Chinese herbal medicine juice with an insect killing function is added, so that the fresh water polyculture fish compound biological pesticide fertilizer is good in water solubility, can quickly cultivate planktons in a pond to provide baits for the polyculture fish, can improve water quality, can increase dissolved oxygen, can restrain and reduce diseases, and can regulate a micro-ecological environment in offspring seed organisms of the polyculture fish to improve the immunity of the polyculture fish.

Description

technical field [0001] The invention relates to the technical field of biological fish fertilizer, in particular to a compound biological medicinal fertilizer for freshwater mixed fish and a preparation method thereof. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. With the rapid development of the aquaculture industry, the feed industry is also developing rapidly, and so is the fish farming industry. How to promote the growth of fish is an important issue facing animal breeding, and the development of new feed varieties has also received widespread attention. [0003] Freshwater fishes have their own habitat and feeding habits. According to this, generally in the same pond, one kind of freshwater fish is mainly raised while other freshwater f...

Problems solved by technology

Traditional organic fertilizers have their advantages, but their disadvantages are single function, long process of being used by phytoplankton, and consume a lot of oxygen in the water body during the mineralization process, which is not good for the growth of stocking products such as fish in the water; in addition , organic fish fertilizer should be used as base fertilizer, and it is mainly used in winter and spring when the water temperature is low

The function of inorganic fertilizers is relatively single. Although it can increase the yield, long-term use of chemical fertilizers can bring many disadvantages, such as pond soil compaction, poor water quality, pollution of the environment and damage to the ecological balance, and residues in fish will cause serious health problems to people. the harm of

[0008] In response to the above problems, organic and inorganic compound fertilizers have appeared on the market. Although compound fertilizers have absorbed the advantages of both organic and inorganic fertilizers, their shortcomings have not been well overcome.

Neither the compound fish fertilizer nor the single type fish fertilizer can kill the harmful bacteria in the fish pond, and cannot inhibit the reproduction and growth of pathogenic bacteria in the water body. Therefore, it lacks the effect of effective prevention and treatment of fish diseases; at the same time, applying the above fertilizer in the fish pond, The water temperature is greatly affected by external weather changes - such as "cold in late spring", the water quality is unstable, it is difficult for seedlings to adapt, and the emergency response is strong
