Abstract

The invention discloses an organic fertilizer containing silkworm excrement and a preparation method thereof, and relates to the technical field of biological organic fertilizers. The organic fertilizer is prepared by 30-45 parts of mushroom bran, 30-45 parts of thoroughly decomposed and fermented silkworm excrement, 5-10 parts of a phosphatic fertilizer and 5-10 parts of a potash fertilizer. The preparation method comprises the following steps: the thoroughly decomposed and fermented silkworm excrement and the mushroom bran are uniformly mixed, and piled for natural fermentation, after fermentation is performed for 5 days, the phosphatic fertilizer and the potash fertilizer are added and uniformly mixed, and a product is obtained after granulation and drying. The organic fertilizer has high organic content and long fertilizer efficiency, contains comprehensive nutrient elements and can accelerate growth of fruits and vegetables; and further, the cultivation time is shortened, and the cultivation cost is reduced.

Description

A kind of silkworm excrement organic fertilizer and preparation method thereof

Technical field

The present invention relates to technical field of biological organic fertilizer, especially a kind of silkworm excrement and bacterium chaff are silkworm excrement biological organic fertilizer of main raw material and preparation method thereof.

Background technology

China is sericulture state maximum in the world, silkworm excrement is the mixture of the bedding and padding in the solid manure residual mulberry that also mixing food is surplus and silkworm rearing bed of being discharged by the larva of silkworm in sericulture process, containing abundant nutritive substance and a small amount of plant growth physiological regulation agent, containing organism 77.68-81.15 in the ight soil dry-matter of silkworm, nitrogenous 2.97%, phosphorous 1.03%, containing potassium 3.52 and other trace element, there is good agronomical value.

At present, for the process of silkworm excrement, be generally directly used in farmland fertilizer or abandon, but because fresh silkworm excrement is with certain pathogenic bacteria, directly as fertilizer or abandon all can to environment.

Bacterium chaff, be by cultivation edible mushroom collection after substratum residuum, be commonly called as edible fungus culturing waste material, bacterium slag or clout.After the enzymolysis of the various enzymes that these culture materials are secreted through edible fungus mycelium, the macromolecular substance such as the Mierocrystalline cellulose contained in its culture material, hemicellulose, xylogen, protein are all by degraded in various degree and utilization, the content of crude protein and crude fat is improved, and be rich in the several kinds of mineral elements such as amino acid, polysaccharide and calcium, phosphorus, iron, zinc, also create organic acid and biologically active substance etc. simultaneously, this adds increased the content of bacterium chaff Middle nutrition composition.

At present, except minority bacterium chaff is further processed utilization, the overwhelming majority remains and is discarded or carry out combustion in-situ, both pollutes environment, wastes again the useful matter be rich in bacterium chaff.

Summary of the invention

Problem to be solved by this invention is to provide and a kind ofly can well make use of silkworm excrement organic fertilizer of the nutritive ingredient be rich in silkworm excrement and bacterium chaff and preparation method thereof.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

It is made up of the raw material of following weight part: bacterium chaff 30-45 part, the silkworm excrement 30-45 part of fermentation of becoming thoroughly decomposed, phosphate fertilizer 5-10 part, potash fertilizer 5-10 part;

Its preparation method is:

The preparation of the silkworm excrement of A, fermentation of becoming thoroughly decomposed: silkworm excrement is laid on the ground, and tiling thickness is 18-20 centimetre; The oligosaccharides, the dry yeast that are 20% concentration stir obtain fermented liquid in after the ratio mixing of 300:1, fermented liquid is sprayed on the silkworm excrement all completed, to silkworm excrement is wet through, then build with plastics film and ferment, ferment and open film after 20 days and carry out turning, build again after turning and continue fermentation 15 days, to obtain final product;

The preparation of B, bacterium chaff: moistening sugarcane leaf grinding 60 parts is fully mixed rear feeding fermenter with 20 parts of filter muds, 0.5 part of calcium superphosphate, 1 part of rice bran and l part gypsum, add 0.5 part of dry yeast and carry out pile-fermentation, ferment and carry out turning after 20 days, Secondary Fermentation after turning, described Secondary Fermentation process first temperature in fermenter is adjusted to 58 DEG C ~ 60 DEG C sterilizings that carry out disinfection, and then be cooled to 42 DEG C ~ 52 DEG C, and carry out heat-preservation fermentation at such a temperature 10 days; When being cooled to below 30 DEG C, being sent in bacterium room by described fermentation materials and carry out edible fungus culturing, when edible mushrooms is ripe, by edible mushroom collection, namely remaining material is described bacterium chaff;

C, mixed with the bacterium chaff of step B gained by the silkworm excrement of the fermentation of becoming thoroughly decomposed of step A gained, wet heap carries out spontaneous fermentation, ferments after 5 days, adds phosphate fertilizer and potash fertilizer mixes, granulation, and namely oven dry obtains this silkworm excrement organic fertilizer.

Owing to adopting technique scheme, the present invention has following beneficial effect:

1. the present invention obtains using silkworm excrement and bacterium chaff by fermentation as main raw material, and therefore organic content is high, and its nutritive element contained is comprehensive, and fertilizer efficiency is long, thus can effectively improve soil shape and biological activity.

2. the present invention is used in the cultivation of fruit, vegetables, its growth can be accelerated, shorten planting time, reduce cultivation cost, and due to the raw material of silkworm excrement organic fertilizer of the present invention natural, do not contain hazardous substance, thus cultivate obtain fruit, quality of vegetable is good, output is high.

3, this fertilizer wide material sources, resource is easy to get, with low cost, production process is pollution-free.

4, silkworm excrement resource is disposable is processed, and solves the pollution that discarded silkworm excrement causes ecotope.
