Abstract

A quickly acting mixed fertilizer containing NPK (25%) and organic substance (20% or more) is prepared from castor cake or bean cake (30-40%), humic acid (7-10), Chinese medical stone (7-10), water preserving agent (1-3), effective microbes (0.1-0.5), urea (12-16), ammonium phosphate (12-16) and potassium chloride (11-15) through fermenting, pulverizing, and mixing. Its advantages are multiple functions, quickly taking its effect, improving soil, and concentrated fertilizer.

Description

Quick-acting compound organic and inorganic fertilizers and production method

Technical field

The invention belongs to fertilizer and preparation thereof, particularly a kind of quick-acting compound organic and inorganic fertilizers and production method.

Background technology

The organic-inorganic compound fertilizer of prior art, how its organic component is made with the spontaneous fermentation of the peat composed of rotten mosses, farm manure, cake fertilizer.Though certain infertile field effect is arranged, and its fertilizer efficiency is lower, function singleness.

Summary of the invention

Purpose of the present invention is intended to solve the deficiencies in the prior art, develops a kind of multi-functional, compound organic and inorganic fertilizer that fertilizer efficiency is high.Its technical scheme is: the content sum total≤25% of the nitrogen of these quick-acting compound organic and inorganic fertilizers, phosphorus, potassium composition, organic 〉=20%, medical stone 7.0～12%, water-holding agent 1.0～1.3%.Its preparation method comprises: raw material and proportioning: Semen Ricini cake or soya-bean cake 30～40%, humic acid 7.0～10%, medical stone 7.0～10%, water-holding agent 1.0～3.0%, EM effective microbe 0.1～0.5%, urea 12～16%, ammonium phosphate 12～16%, Repone K 11～15%;

Operation steps:

A, batching: Semen Ricini cake or soya-bean cake 60～70%, humic acid 15～20%, medical stone 15～20%, water-holding agent 1.0～3.0%, EM effective microbe 0.1～0.5%;

B, fermentation: the batching thorough mixing of a stirred block evenly, spray adds water 30～40% again, and normal temperature sealed fermenting 5～15 days promptly makes efficient organic fertilizer;

C, powder process: the fertilizer drying and dehydrating (water-content is less than 20%) with b grinds into powder;

D, be mixed: the organic fertilizer powder that c is made adds urea 12～16%, ammonium phosphate 12～16%, Repone K 11～15% again, and thorough mixing stirs, and promptly gets quick-acting compound organic and inorganic fertilizer finished products.

Among the above-mentioned preparation method, as proceed to c during the step, can make the multifunctional organic fertilizer finished product.Finish when d goes on foot, promptly make quick-acting compound organic and inorganic fertilizers.

Key problem in technology of the present invention is with the processing of organic matter raw material through efficacious microbial colony, the multifunctional bio fertilizer that makes.So it not only can improve Soil structure for plant provides required nutrient, and has functions such as fixed nitrogen, phosphorus decomposing, potassium decomposing, decomposition remains of pesticide, water conservation drought resisting, is a kind of quick-acting concentrated fertilizer.

Embodiment

Embodiment 2: quick-acting compound organic and inorganic fertilizers and production method, adopt following step to finish:

A, batching: Semen Ricini cake or soya-bean cake 60～70%, humic acid 15～20%, medical stone 15～20%, water-holding agent 1.0～3.0%, EM effective microbe 0.1～0.5%;

B, fermentation: the batching thorough mixing of a is stirred, and spray adds water 30～40% again, and normal temperature sealed fermenting 5～15 days promptly makes multifunctional organic fertilizer;

C, powder process: the fertilizer drying and dehydrating (water-content is less than 20%) with b grinds into powder;

D, be mixed: the organic fertilizer powder that c is made adds urea 12～16%, ammonium phosphate 12～16%, Repone K 11～15% again, and thorough mixing stirs, and promptly gets quick-acting compound organic and inorganic fertilizer finished products.
