【摘要】："全元"復(fù)合微生物肥料集化肥速效、有機肥長效和生物肥增效于一體,使肥料養(yǎng)分釋放均衡持久,達到使作物增產(chǎn)增收的目的。但目前"全元"復(fù)合微生物肥料多為粉狀,具有容易結(jié)塊,大小不均,不利于機械化施用等缺點,將肥料造粒成為生產(chǎn)實際的迫切需求。首先利用生物有機肥添加一定配比無機化肥形成不同養(yǎng)分"全元"復(fù)合微生物肥料,進而利用圓盤造粒機研究了復(fù)合微生物肥料造粒工藝。結(jié)果表明,原料粉碎細度,水分和肥料配方對復(fù)合微生物肥料成粒效果均有影響;原料細度方面,只過18目篩的混合原料造粒效果最好,成粒所需水分最低,原料過細容易產(chǎn)生大顆粒,造粒不均勻;生物有機肥造粒所需水分最高,隨著加入無機化肥的比例增加,肥料造粒所需水分呈下降趨勢;同時添加無機氮磷鉀的配方成粒效果好,且無機養(yǎng)分比重對成粒有影響;無機化肥中過磷酸鈣能明顯增加肥料黏性,硫酸銨和氯化鉀增加黏性的效果不明顯。結(jié)論:"全元"復(fù)合微生物肥料同時添加無機氮磷鉀造粒時,無需添加工業(yè)粘結(jié)劑即可有效成粒,成粒均勻且效率高,同時,生產(chǎn)實際中只需粉碎原料后過18目篩即可達到造粒要求。
[Abstract]:"whole element" compound microbial fertilizer is an effective fertilizer, organic fertilizer has long effect and biological fertilizer increase efficiency, which makes fertilizer nutrient release balanced and lasting, and achieves the purpose of increasing crop yield and income. But at present, "all element" compound microbial fertilizer is mostly powdery. It has the disadvantages of easy agglomeration, uneven size, bad mechanization and so on. It is an urgent need to granulate fertilizer. Firstly, biological organic fertilizer is added to inorganic fertilizer with certain proportion to form "all-element" compound microbial fertilizer with different nutrients. The granulation technology of compound microbial fertilizer was studied by using disc granulator. The results showed that the granulation effect of compound microbial fertilizer was affected by raw material crushing fineness, moisture content and fertilizer formula. The mixed raw materials with only 18 mesh sieve have the best granulation effect, the minimum water content is needed for granulation, and the large grain size is easy to be produced when the raw material is too fine, and the water content required for bio-organic fertilizer granulation is the highest, with the increase of the proportion of inorganic fertilizer added, The moisture content of fertilizer granulation showed a decreasing trend, and the formula of adding inorganic nitrogen, phosphorus and potassium had a good effect on granulation, and the specific proportion of inorganic nutrients had an effect on the granulation, and calcium superphosphate in inorganic fertilizer could obviously increase the viscosity of fertilizer. The effect of ammonium sulfate and potassium chloride on viscosity increase is not obvious. Conclusion: when adding inorganic nitrogen, phosphorus and potassium to compound microbial fertilizer at the same time, it can be effectively granulated without adding industrial binder, and the granulation is uniform and efficient, at the same time, In practice, only crushing raw materials after 18 mesh sieve can meet the requirements of granulation.
