Abstract
The invention discloses a biomass charcoal-coated slow release fertilizer preparation technology. The preparation technology comprises adding a binder into urea and bonding biomass charcoal to the urea. The coated slow release fertilizer utilizing biomass charcoal as a coating material and a polyvinyl alcohol aqueous solution with content of 5.0% as a binder has expected slow release effects, has a nutrient release speed decreased along with coating thickness increasing, has a smooth integral nitrogen accumulation release process, has a nutrient release amount of about 80% in culture for about 30 days and is suitable for nutrition demands of a crop with a short growth period.
Description
Technical field
The present invention relates to fertilizer field, be specifically related to the preparation technology of a kind of biomass carbon bundled slow-releasing fertilizer。
Background technology
Slow release fertilizer can not only improve utilization rate of fertilizer, moreover it is possible to reduces the fertilising negative effect to environment, causes the extensive concern of scholar in recent years。The research of current coated slow release fertilizer is concentrated mainly in selection and the research and development of coated fertilizer, and organic high molecular polymer coated slow release fertilizer can slow down nutrients release, improves fertilizer utilization efficiency, has obtained general approval。But it mostly uses liposoluble substance in process of production, easily to environment after using, the reason such as expensive, limits the popularization and application of this kind of fertilizer in addition。Therefore, seek environmental friendliness, the study hotspot that cheap, had good sustained release effect membrane material becomes this field。Biomass carbon has the pore structure of height, it is possible to increases soil porosity and strengthens retention capacity of soil, reducing soil bulk density, favourable plant root growth；Contain the nutrient needed for a large amount of plant simultaneously, promote soil nutrient circulation and plant growing；Also there is higher biological stability, the ability of stronger opposing microbial decomposition, it is possible to strengthen the carbon solidification effect of soil, reduce the carbon release to air。If biomass carbon is prepared coated slow releasing fertilizer as membrane material, fertilizer nutrient rate of release can not only be slowed down, improve utilization rate of fertilizer, and good ecological environment benefit can be brought。
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that the preparation technology of the biomass carbon bundled slow-releasing fertilizer of a kind of had good sustained release effect。
For realizing above-mentioned technique effect, the technical scheme is that the preparation technology of a kind of biomass carbon bundled slow-releasing fertilizer, it is characterised in that comprise the following steps:
S1: poured into by the urea granules of uniform particle sizes in the rotary drum of rotation, heating, to 40 DEG C, sprays bonding agent to carbamide；
S2: joined by carbonization rice husk in rotary drum, sprays bonding agent simultaneously and makes material roll granulating, repeatedly several times, until by complete for all carbonization rice husks parcel, obtaining biomass carbon bundled slow-releasing fertilizer。
Wherein, the granularity of described carbonization rice husk is 40～60 orders。
Wherein, described bonding agent is polyvinyl alcohol water solution。
Wherein, the percentage by weight of the middle polyvinyl alcohol of described polyvinyl alcohol water solution is 4～6%。
Wherein, described carbonization rice husk consumption is the 10～20% of urea granules weight。
Advantages of the present invention and having the beneficial effects that:
Biomass carbon is as lapping, the polyvinyl alcohol water solution of 5.0% can reach intended slow release effect as the coated slow releasing fertilizer of bonding agent, nutrient releasing speed thickens along with integument and diminishes, overall Nitrogen Accumulation release process ratio is shallower, and it is about 80% cultivating about the 30th day nutrients accumulation burst size, illustrate that this coated slow releasing fertilizer is applicable to the nutritional need of the shorter crop of period of duration。
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described。Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this。
Embodiment 1
The preparation technology of the biomass carbon bundled slow-releasing fertilizer of embodiment 1, comprises the following steps:
S1: poured into by the urea granules of uniform particle sizes in the rotary drum of rotation, heating, to 40 DEG C, sprays bonding agent to carbamide；
S2: joined by carbonization rice husk in rotary drum, sprays bonding agent simultaneously and makes material roll granulating, repeatedly several times, until by complete for all carbonization rice husks parcel, obtaining biomass carbon bundled slow-releasing fertilizer。
Wherein, the granularity of carbonization rice husk is 40 orders。
Wherein, bonding agent is polyvinyl alcohol water solution。
Wherein, the percentage by weight of the middle polyvinyl alcohol of polyvinyl alcohol water solution is 4%。
Wherein, carbonization rice husk consumption is the 10% of urea granules weight。
Embodiment 2
The preparation technology of the biomass carbon bundled slow-releasing fertilizer of embodiment 2, comprises the following steps:
S1: poured into by the urea granules of uniform particle sizes in the rotary drum of rotation, heating, to 40 DEG C, sprays bonding agent to carbamide；
S2: joined by carbonization rice husk in rotary drum, sprays bonding agent simultaneously and makes material roll granulating, repeatedly several times, until by complete for all carbonization rice husks parcel, obtaining biomass carbon bundled slow-releasing fertilizer。
Wherein, the granularity of carbonization rice husk is 60 orders。
Wherein, bonding agent is polyvinyl alcohol water solution。
Wherein, the percentage by weight of the middle polyvinyl alcohol of polyvinyl alcohol water solution is 6%。
Wherein, carbonization rice husk consumption is the 20% of urea granules weight。
Embodiment 3
The preparation technology of the biomass carbon bundled slow-releasing fertilizer of embodiment 3, comprises the following steps:
S1: poured into by the urea granules of uniform particle sizes in the rotary drum of rotation, heating, to 40 DEG C, sprays bonding agent to carbamide；
S2: joined by carbonization rice husk in rotary drum, sprays bonding agent simultaneously and makes material roll granulating, repeatedly several times, until by complete for all carbonization rice husks parcel, obtaining biomass carbon bundled slow-releasing fertilizer。
Wherein, the granularity of carbonization rice husk is 50 orders。
Wherein, bonding agent is polyvinyl alcohol water solution。
Wherein, the percentage by weight of the middle polyvinyl alcohol of polyvinyl alcohol water solution is 5%。
Wherein, carbonization rice husk consumption is the 15% of urea granules weight。
Lapping all can form relatively complete integument and cover on urea granules, charring rice husk consumption is more big, membrane wrapping thickness increases, lapping is also more complete to granulated fertilizer parcel, making fertilizer nitrogen initial stage rate of release reduce, can be considered poroid material between integument granule and granule, hydrone is dissipated to fertilizer core by these holes, integument thickness increases, and it is long that moisture enters the fertile heart time。
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention。
