Abstract
The invention discloses a urea formaldehyde controlled-release fertilizer. The fertilizer comprises the following raw materials in parts by weight: 50-100 parts of urea formaldehyde powder, 2-4 parts of sulfuric acid, 10-20 parts of copper sulfate, 10-20 parts of ferrous chloride and 15-30 parts of compound probiotics. The controlled-release nitrogen content is guaranteed, the fertilizer is processed by directly using the urea formaldehyde powder as a central raw material, the problem of insufficient fertilizer controlled-release nitrogen caused by the high water content of the urea formaldehyde solution when the urea formaldehyde solution is taken as the raw material in the traditional fertilizer using process is solved, the high-yield fertilization requirement is met, the physicochemical property of the soil is improved and the soil is improved.
Description
Technical field
The present invention relates to technical field of agricultural fertilizers, specifically belong to a kind of urea aldehyde slow release fertilizer.
Background technology
Current agriculture main fertilizer is based on the chemical fertilizer of the macroelement of nitrogenous, phosphorus, potassium, and crop can play the effect of supplementary respective element after using, have certain effect of increasing production to crop.But the utilization ratio of fertilizer is very low, a large amount of phosphorus, potassium element can not effectively be utilized by crop and be trapped in soil, and nutritive element waste is serious, causes environmental pollution.And after soil life-time service chemical fertilizer, soil compaction is serious, organic microbial reduces, even soil pollution.Existing organic fertilizer refers to the fertilizer that natural organic matter undergoes microbial fermentation, urea-formaldehyde fertilizer is the fertilizer of urea and formaldehyde condensation, current organic fertilizer does not have slow releasing function, and urea-formaldehyde fertilizer lacks natural biomass, and causing has shortcoming separately.
Summary of the invention
For the problems referred to above; the object of this invention is to provide a kind of urea aldehyde slow release fertilizer; picking of raw material; guarantee slow-release nitrogen content; direct use urea aldehyde powder processes as intermediate raw material, to avoid when conventional fertilizers uses urea aldehyde liquid to make raw material because of the high problem causing fertilizer slow release nitrogen hunger of urea aldehyde liquid water content, can meet the needs of high-yield fertilization; the physico-chemical property of soil can be improved again, improvement soil.
The technical solution used in the present invention is as follows:
A kind of urea aldehyde slow release fertilizer, described fertilizer comprises following raw material by weight and makes: urea aldehyde powder 50 ~ 100 parts, 2 ~ 4 parts, sulfuric acid, 10 ~ 20 parts, copper sulfate, iron protochloride 10 ~ 20 parts, compound probiotic 15 ~ 30 parts.
Described urea aldehyde powder is mixed by treated starch 1 ~ 10 part, 25 ~ 45 parts, urea, 25 ~ 45 parts, formaldehyde.
Described raw material also comprises cow dung 60 ~ 90 parts, stalk 40 ~ 90 parts, donkey bone meal 50 ~ 80 parts, stablizer 2 ~ 5 parts, 2 ~ 5 parts, sorbent material.
Described compound probiotic comprises: one or more in yeast, Bacillus subtillis, bacillus licheniformis.
Described stablizer is composite lead heat stabilizer.
Described sorbent material is calcium carbonate mineral powder or calcium chloride mineral powder.
A preparation method for urea aldehyde slow release fertilizer, comprises the following steps:
1) obtain starch paste by soluble in water for treated starch, by soluble in water for formaldehyde be mixed with 37% formaldehyde solution, starch paste and formaldehyde solution are added in reactor, add urea simultaneously and obtain solution I;
2) cow dung, stalk are clayed into power, add the mixing of donkey bone meal, obtain mixtures II;
3) mixtures II is added in solution I to stir obtain solution III, in solution III, add copper sulfate, iron protochloride and compound probiotic mix and obtain urea aldehyde slow-release fertilizer.
Compared with the prior art, beneficial effect of the present invention is as follows:
Picking of raw material of the present invention; guarantee slow-release nitrogen content; direct use urea aldehyde powder processes as intermediate raw material; avoid when conventional fertilizers uses urea aldehyde liquid to make raw material because of the high problem causing fertilizer slow release nitrogen hunger of urea aldehyde liquid water content; the needs of high-yield fertilization can be met; the physico-chemical property of soil can be improved again, improvement soil.
