Organic/inorganic composite biological pesticide-fertilizer special for crabs and preparation method thereof

Abstract

The invention discloses an organic / inorganic composite biological pesticide-fertilizer special for crabs and a preparation method thereof. The organic / inorganic composite biological pesticide-fertilizer special for crabs is composed of the following components in parts by weight: 50-60 parts of chicken manure, 15-20 parts of greenhouse garbage, 10-15 parts of straw powder, 15-20 parts of acidolysis slag, 8-10 parts of sawdust, 10-12 parts of bone meal, 0.1-0.2 part of bacillus subtilis, 0.1-0.2 part of aspergillus oryzae, 0.1-0.2 part of saccharomyces cerevisiae, 3-6 parts of pomegranate rind, 2-4 parts of azadirachta indica, 5-7 parts of lygodium japonicum root, 5-7 parts of celastrus orbiculatus, 2-5 parts of fiveleaf akebia fruit, 3-6 parts of copper sulphate, 12-14 parts of potassium sulfate, 12-14 parts of ammonium bicarbonate, 10-12 parts of calcium superphosphate and 10-14 parts of urea. The organic / inorganic composite biological pesticide-fertilizer special for crabs is subjected to fermentation and added with Chinese herbal medicine juice with insecticidal function, and is capable of improving water quality, increasing dissolved oxygen, enhancing crab immunity, effectively reducing diseases and improving crab yield.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to an organic-inorganic composite biological fertilizer specially used for crabs and a preparation method thereof. Background technique [0002] Disposal of domestic waste is one of the keys to environmental protection. The current state of social development is that with the gradual improvement of people's living standards, more and more domestic waste is produced. Citizens require the harmless treatment of domestic waste, which is a major issue of sustainable social development in front of people. Therefore, the harmless and resourceful treatment of domestic waste is currently the preferred subject. [0003] In the prior art, there are two main types of fertilizers used in aquaculture, i.e. organic fertilizers and chemical fertilizers. Traditional organic fertilizers have their advantages, but their disadvantages are single function, long process of being used by ...

AI Technical Summary

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 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 fertilizer is relatively single. Although it can increase the yield of fish, long-term use can bring many disadvantages, such as pond soil compaction, pollution of the environment, destroying the ecological balance, and residual crabs in the body will cause serious harm to human health.

[0004] 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 harmful bacteria in the pond, and cannot inhibit the reproduction and growth of pathogenic bacteria in the water body. Therefore, it lacks the effect of effectively preventing and treating crab diseases; at the same time, applying the above fertilizer in the 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
