［産業上の利用分野］
本発明は粒状腐植酸燐酸肥料であって、特に水溶性燐酸

るものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a granular humic acid phosphate fertilizer, which is particularly capable of stably supplying a water-soluble phosphoric acid content, has excellent disintegrability, and is highly effective for plant growth. The present invention relates to a granular humic acid phosphate fertilizer effective for promotion.
［従来の技術］
燐酸質肥料の種類には、肥料取締法の規定に基づく各種
の燐酸質肥料がある。これらのうち、「加工燐酸肥料」
は、燐酸質、鉱滓に燐酸等の酸を添加した肥料であり、
く水溶性燐酸分１５６０％以上及び水溶性燐酸分１％以
」二を保証する肥料である。[Prior Art] There are various types of phosphoric acid fertilizers based on the provisions of the Fertilizer Control Law. Among these, "processed phosphoric acid fertilizer"
is a fertilizer made by adding acids such as phosphoric acid to mineral slag,
This fertilizer guarantees a water-soluble phosphoric acid content of 1560% or more and a water-soluble phosphoric acid content of 1% or more.
また、「腐植酸燐酸肥料」は、石炭又は亜炭を硝酸で分
解した腐植酸に溶成燐肥、焼成燐肥、燐鉱石又は塩基性
のマグネシウム含有物、硫酸又は燐酸を加えたものであ
り、上記「加工燐酸肥料」と同量のく溶性燐酸分及び水
溶性燐酸分を保証する肥料である。In addition, "humic acid phosphate fertilizer" is a product obtained by adding dissolved phosphorous fertilizer, calcined phosphorous fertilizer, phosphate rock or basic magnesium-containing material, sulfuric acid or phosphoric acid to humic acid obtained by decomposing coal or lignite with nitric acid, This fertilizer guarantees the same amount of soluble phosphoric acid and water-soluble phosphoric acid as the above-mentioned "processed phosphoric acid fertilizer".
［発明が解決しようとする課題］

料袋中で肥料中の水溶性燐酸分と反応するため、水溶性
燐酸分が著しく減少する。[Problems to be Solved by the Invention] Usually, the above-mentioned "processed phosphate fertilizer" and "humic acid phosphate fertilizer" contain trace elements such as Mg and Ca for "soil preparation." The above-mentioned Mg and Ca are contained in the melted phosphorus fertilizer production process, and are mixed in by adding serpentine to the calcined phosphorus fertilizer, but these basic components are added to the water-soluble fertilizer in the fertilizer bag. Because it reacts with phosphoric acid, water-soluble phosphoric acid content decreases significantly.
従って、規定量の水溶性燐酸分を保証するためには上記
反応によるロス分を見
越し、水溶性燐酸分を過剰に添加することが必要になる
が、そのためコスト高となるのを避けることができない
。Therefore, in order to guarantee the specified amount of water-soluble phosphoric acid, it is necessary to add an excessive amount of water-soluble phosphoric acid in anticipation of the loss due to the above reaction, but this inevitably increases costs. .
上記水溶性燐酸の減少を防＋、ｌｚするために、燐酸肥

ｇ、 Ｃａ等の微量成分を土中に供給でき、また腐植酸
による土壌改良効果を併せ持つ優れた肥料である。In order to prevent the above-mentioned decrease in water-soluble phosphoric acid, a "humic acid phosphorus fertilizer" in which humic acid is added to a phosphoric acid fertilizer has been developed (Japanese Patent Publication No. 8, No. 8, No. 60-63 J). The humic acid phosphorus fertilizer contains humic acid that reacts with basic components such as Mg and Ca, and can mask iJg, Ca, etc. in advance, so it can prevent the reduction of water-soluble phosphoric acid, and
It is an excellent fertilizer that can supply trace components such as g and Ca into the soil, and also has the soil improvement effect of humic acid.
しかし、上記肥料は、燐酸分の供給源として溶成燐肥及
び過燐酸石灰、看過燐酸石灰又は燐酸等（以下燐酸と略
す）の２種に依存しており、必然的にコスト高になる。However, the above-mentioned fertilizer relies on two types of phosphoric acid sources: melted phosphorous fertilizer and superphosphoric lime, neglected phosphoric acid lime, or phosphoric acid (hereinafter abbreviated as phosphoric acid), which inevitably leads to high costs.
また、燐酸の供給源として焼成燐肥を使用することも考
えられるが、粒状化した場合に崩壊性が悪く、燐酸分を
確実に保証することができない。It is also possible to use calcined phosphorous fertilizer as a source of phosphoric acid, but it has poor disintegration properties when granulated, and the phosphoric acid content cannot be reliably guaranteed.
本発明は、水溶性燐酸分の含有量を高くし、しかも粒状
化した場合でも施肥俊速やかに崩壊し、植物の成長促進
を図ることができる粒状腐植酸燐酸肥料を提供すること
にある。An object of the present invention is to provide a granular humic acid phosphate fertilizer which has a high content of water-soluble phosphoric acid, and which can be quickly disintegrated even when granulated to promote plant growth.
［課題を解決するためのｆ段］
上記目的を達成するために、本発明は次の事項を骨子と
するものである。[Step F for Solving the Problem] In order to achieve the above object, the present invention has the following points as its main points.
即ち、本発明は腐植酸と、金属Ｍｇを精錬する際に副生
ずるマグネシウムスラブと、燐酸とを主成分とする粒状
腐植酸燐酸肥料である。That is, the present invention is a granular humic acid phosphate fertilizer whose main components are humic acid, a magnesium slab produced as a by-product when refining metal Mg, and phosphoric acid.
本発明に使用する腐植酸は、亜炭、
褐炭、草炭等の若年炭を粉砕し、これに硝酸を添加し酸
化分解せしめたものが用いられる。上述腐植酸は土壌中
における塩基吸収能の大なるものであることは良く知ら
れている。The humic acid used in the present invention is obtained by pulverizing young coal such as lignite, brown coal, grass charcoal, etc., and adding nitric acid to the pulverized young coal for oxidative decomposition. It is well known that the humic acids mentioned above have a large ability to absorb bases in soil.
また、マグネシウムスラグは、酸化マグネシウムをＡＩ
テルミット反応で金属Ｍｇを製造する際副生ずるスラグ
で、その代表的組成を第１表に例示する。In addition, magnesium slag uses magnesium oxide as an AI
Slag is a by-product when producing metallic Mg by thermite reaction, and its typical composition is illustrated in Table 1.

適宜軽焼マグネシウムを混合し、製品中のＭｇを増量す
ることができる。Table 1 (Unit weight %) [Function] To illustrate the production method of the present invention, humic acid, magnesium slag and phosphoric acid are mixed. In this case, the mixing ratio of the raw materials is approximately 15 to 30% by weight of humic acid, 35 to 45% by weight of magnesium slag, and 30 to 50% by weight of phosphoric acid. Incidentally, the amount of Mg in the product can be increased by appropriately mixing lightly calcined magnesium with the magnesium slag.
即ち、マグネシウムスラグ中のＭｇ、 Ｃａは混合され

ましくなく、一部のＭｇ、 Ｃａを腐植酸と反応させて

もので、」二記配合割合とすることによって、高い水溶
性を保証することができる。That is, Mg and Ca in the magnesium slag react with the mixed phosphoric acid to form a soluble phosphoric acid component. However, it is not preferable for all of these Mg and Ca to react with phosphoric acid, and by masking some of the Mg and Ca by reacting with humic acid, water-soluble phosphoric acid content is ensured. By doing so, high water solubility can be guaranteed.
さらに、本発明は〈溶性燐酸としての溶成燐肥をまった
く使用する必要がなく、しかも腐植酸の配合割合を調整

に応じて適宜コントロールできる燐酸肥料を提供するこ
とができる。Furthermore, the present invention eliminates the need to use dissolved phosphorus fertilizer as soluble phosphoric acid at all, and furthermore, by adjusting the blending ratio of humic acid, the soluble phosphoric acid content and water-soluble phosphoric acid content can be controlled as necessary. Phosphate fertilizer can be provided.
また、本発明は、これを１〜５ｍｍに造粒するものであ

できる。In addition, in the present invention, this is granulated to a size of 1 to 5 mm, and in addition to making it easier to handle, the granulated material collapses into the cylinder after fertilization, so it can increase the fertilizing effect. .

Table 3 shows the particle size of the pellets, the water-soluble phosphoric acid content (C p2o5 in the table), the water-soluble phosphoric acid content (w-p2o6 in the table), and the disintegrability of the product. From Table 3, the crushing strength of the green pellets is 1 kg or less, but after drying, it is as hard as about 2 kg. However, when immersed in water for 24 hours, the
It can be confirmed that it collapses rapidly at 100 g.
