Grass carp special-purpose organic-inorganic composite biological medicinal fertilizer and preparation method thereof

Abstract

The invention discloses grass carp special-purpose organic-inorganic composite biological medicinal fertilizer and a preparation method thereof. The grass carp special-purpose organic-inorganic composite biological medicinal fertilizer comprises, by weight, 55-65 parts of chicken manure, 20-25 parts of sugar residues, 10-15 parts of straw powder, 8-10 parts of bone meal, 0.1-0.2 parts of bacillus subtilis, 0.1-0.2 parts of aspergillus oryzae, 0.1-0.2 parts of saccharomyces cerevisiae, 5-7 parts of betel nut, 4-6 parts of Chinese prickly ash, 4-6 parts of coptis root, 4-6 parts of celastrus orbiculatus, 2-4 parts of copper sulfate, 12-14 parts of potassium sulfate, 12-14 parts of ammonium bicarbonate, 8-12 parts of calcium superphosphate and 12-14 parts of urea. Fermented fertilizer materials are mixed and juices of the Chinese herbal medicines having functions of killing insect pests are added into the mixture. Therefore, the grass carp special-purpose organic-inorganic composite biological medicinal fertilizer improves water quality, increases dissolved oxygen, inhibits and reduces diseases, adjusts a body internal micro-ecological environment of a grass carp fry, improves immunity, effectively reduces diseases, fast cultures planktons in a pool, is used as a grass carp bait, and improves a grass carp yield.

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 grass 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.

Problems solved by technology

[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
