Embodiment Construction

[0024] The solid fermentation and liquid fermentation of the present invention are described in detail below in conjunction with 6 examples, but the present invention is not limited to the given examples.

[0025] Table 1 The raw material ratio table of the solid fermentation step of embodiment 1-6

[0026]

[0027] In the embodiment, the solid EM Bokashi and chicken manure were mixed according to the above weight, piled up, covered with a plastic film, and fermented under airtight conditions, wherein the plastic film was turned over once every other week, and in the process of turning over Spray 1% liquid EM, then cover the film to continue fermentation, after 21-25 days of fermentation, dry it.

[0028] Measured by standard methods, the pH range of the bio-organic fertilizer made in each embodiment is 7-7.5; the C / N value range is 12-15; the NO 3 - -N / NH 4 + -N value ≥ 3.5; total nitrogen ≥ 1.6%; total phosphorus ≥ 1.4%; total potassium ≥ 1.2%; effective viable count...

Abstract

The invention relates to a preparation method of a biological organic and inorganic mixed liquid fertilizer. The preparation method comprises the steps of evenly mixing materials according to the ratio of EM solid glass Cassie to dried poultry litter to 1% EM stoste being (5-8) to (88-92) to (3-4) (parts by weight), yarding and fermenting for 21-25 days at room temperature, airing until the moisture content is lower than or equal to 30wt%; putting the materials into a fermentation tank according to the ratio of an ingredient to EM active carbon of 1 to 9 (weight ratio); hermetically fermenting for 5-7 days under an intermittent mixing condition; filtering the fermentation liquor to remove insoluble substance to obtain the clear liquid and store; mixing nutrients of nitrogen, phosphorus and potassium in the filtrate, so that the content ratio of nitrogen to phosphorus to potassium achieves the ratio of N to P2O5 to K2O being 1 to 2 to 2.5 (weight ratio), and N+P2O5+K2O is higher than or equal to 110g / L, and storing and bottling the materials. The preparation method disclosed by the invention is fast in fermentation speed, short in preparation period, and high in fermentation degree; the efficient biological organic and inorganic mixed liquid fertilizer can be obtained, and the preparation method has the effects of comprehensive nutrition, high fertilizer efficiency, nuisanceless property and obvious yield-increasing effect of crop.

Description

technical field [0001] The invention relates to a biological liquid fertilizer, in particular to a method for preparing high-efficiency biological organic-inorganic compound liquid fertilizer by using agricultural waste. Background technique [0002] Biological fertilizers use microorganisms or their products as raw materials and have specific fertilizer effects. Due to the wide variety of microorganisms and diverse functions, the research and application of biological fertilizers has great potential under the pressure of energy crisis, resource shortage, and environmental pollution. And it is getting more and more attention from all over the world. Microbial fertilizers can improve soil fertility, improve the utilization rate of chemical fertilizers, inhibit the absorption of nitrate nitrogen, heavy metals, and pesticides by crops, purify and restore soil, reduce the occurrence of crop diseases, promote the utilization of crop straw and urban waste, protect the environment,...
