Abstract
The invention discloses a method for preparing a slow release feed for carps by adopting nano materials. A composite microorganism fish fertilizer specially used for the carps comprises the following components in parts by weight: 2-4 parts of nitrogen-fixing bacteria, 1-3 parts of phosphate solubilizing bacteria, 3-5 parts of enzyme bacteria, 50-60 parts of fish meal, 75-80 parts of bean cakes, 20-30 parts of bran, 70-80 parts of rice bran, 10-14 parts of brown sugar, 8-10 parts of yeast powder, 12-15 parts of edible salt and the like. The composite microorganism fertilizer disclosed by the invention can promote rapid growth of fish and also improve the grade and the quality of the fish, so that diseases of the fish can be reduced; meanwhile, beneficial microorganisms in water can be increased, and the growth of phycophyta in a fishpond is alleviated.
Description
Technical field
The present invention relates to a kind of microbial manure, particularly relate to a kind of complex microorganism fish guano, be specifically related to a kind of carp specific complex microbial fish guano and preparation method thereof, belong to technical field of fertilizers.
Background technology
The protein of carp not only content is high, and quality is also very high, human body digestibility can reach 96%, and contain needed by human body elements such as can supplying with human body essential amino acid, mineral matter, vitamin A and vitamin D, the food that nutritive value is very high, and way is various, very popular.
In the breeding process of carp, need to throw in feed and grow for it, but long-term input feed can grow some harmful bacterias in fishpond and fish pond, these harmful bacterias not only can affect water body environment, are also unfavorable for the growth of carp.And in the breeding process of carp, at present a lot of plants adopt fertilizer, by as throwing in a certain amount of fertilizer in pond, improve the output of carp; Traditional fertilizer has its advantage, but shortcoming function singleness is longer by the process that phytoplankton utilized, and in mineralization process, consumes a large amount of oxygen in water body, this in water to put product in a suitable place to breed as unfavorable in the growth such as fish; In addition, organic fish guano should be made base manure, and is mainly used in Winter-Spring water temperature lower season.And inorganic fertilizer function is comparatively single, although can make fish high yield, use for a long time chemical fertilizer can bring many drawbacks, contaminated environment, destroys the ecological balance.
Except the fertilizer and inorganic fertilizer of simple function, from last century the eighties also start to promote " rational application of fertilizers ", i.e. " composite organic-inorganic fertilizer ", although composite fertilizer has absorbed the advantage of single fertilizer and inorganic fertilizer two aspects, their shortcoming is not fine to be overcome.Existing single type fish guano and compound fish guano also have a common shortcoming, and that can not be killed harmful bacteria exactly, therefore, lack the effectively effect of control of fish disease.The content that can increase beneficial bacterium in fishpond by the compound fish guano of microorganism, effectively reduces the generation of fish diseases, does not also report at present about being exclusively used in the complex microorganism fish guano of carp.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of carp specific complex microbial fish guano and preparation method thereof, comprehensive nutrition is provided can on the one hand the growth of carp, can improve on the other hand the useful content in pond, suppress the breeding growth of pathogen in water body, reduce the generation of disease, improve the yield and quality of carp.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
