Organic-inorganic composite biological medicinal fertilizer exclusively used for silver carp and preparation method thereof

Abstract

The invention discloses organic-inorganic composite biological medicinal fertilizer exclusively used for silver carp and a preparation method thereof. The organic-inorganic composite biological medicinal fertilizer exclusively used for silver carp comprises, by weight, 50-60 parts of chicken manure, 20-25 parts of acidolysis slag, 10-15 parts of straw powder, 8-10 parts of egg shell powder, 0.1-0.2 parts of bacillus subtilis, 0.1-0.2 parts of aspergillus oryzae, 0.1-0.2 parts of saccharomyces cerevisiae, 8-10 parts of stem of oriental bittersweet, 3-4 parts of Azadirachta Indica A.Juss, 4-6 parts of monkshood, 3-5 parts of fiveleaf akebia fruit, 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. Through mixing of the fermented organic and inorganic fertilizer and use of the juice of Chinese herbal medicines having insecticidal functions, water solubility is good. The organic-inorganic composite biological medicinal fertilizer can fast culture planktons in a water pool, provide bait for silver carp, improve water quality, improve dissolved oxygen, inhibit diseases, adjusts the inner micro-ecological environment of a silver carp fry and improves silver carp immunity.

Description

technical field [0001] The invention relates to the technical field of biological fish fertilizer, in particular to a special organic-inorganic compound biological medicine fertilizer for silver carp 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, fish fertilizers used in aquaculture mainly contain two categories, i.e. organic fertilizers and chemical fertilizers. Traditional organic fertilizers have their advantages, but their disadvantages are single function, long process ...

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 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

[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 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
