Abstract
Description
本発明は、散布性と徐効性を兼ねた農業用石灰肥料及びその製造方法に関する。更に詳しくは、散布時の消石灰の飛散がなく、均一な散布が可能で、しかも散布後にも消石灰の効果を持続させる（徐効性）ことが可能な農業用石灰肥料及びその製造方法に関する。 TECHNICAL FIELD The present invention relates to an agricultural lime fertilizer that has both sprayability and sustained action, and a method for producing the same. More specifically, the present invention relates to an agricultural lime fertilizer that can be uniformly sprayed without scattering of slaked lime at the time of spraying, and that can maintain the effect of slaked lime even after spraying (slow effect) and a method for producing the same.
従来から、畑土の酸性化を防止する目的や細菌類の消毒の目的で消石灰の散布が行われている。
これらに用いられる消石灰は、一般に原料である石灰岩を焼成して得られる生石灰（酸化カルシュウム）を水和することにより製造される。こうして製造される消石灰（水酸化カルシュウム）は、無水物でその粒子径も数ミクロンから数百ミクロンの微細粒子状である。
従来の農業用石灰肥料は、かかる微粒子状の消石灰をそのまま使用するために、風が強い日などには、微粒子が風と共に舞いひろがり場合によっては人体や人の目に触れて障害を及ぼすなどのトラブルを生じることがあり、近年、重大な健康問題となっている。
一方、かかる微粒子状のままでは散布時に均一に蒔くことが難しく、散布斑が生じやすい。散布斑があると、散布量が少ない部分は消石灰散布効果が乏しく、散布量が多い部分はアルカリ濃度が高くなり農産物に薬害が生じることがある。
また、散布後の消石灰は、水溶性であることから、降雨により容易に溶解して土中へ浸透し、早期に効果が消失することがある。
Conventionally, slaked lime has been sprayed for the purpose of preventing acidification of field soil and for the purpose of disinfecting bacteria.
The slaked lime used for these is generally produced by hydrating quick lime (calcium oxide) obtained by firing limestone as a raw material. The slaked lime (calcium hydroxide) produced in this way is anhydrous and has a fine particle size of several microns to several hundred microns.
Conventional agricultural lime fertilizer uses such fine slaked lime as it is, so that on windy days, etc., the fine particles may flutter with the wind and in some cases may touch the human body or human eyes and cause damage. Troubles can occur and has become a serious health problem in recent years.
On the other hand, with such fine particles, it is difficult to spread uniformly at the time of spraying, and scattering spots are likely to occur. If there are spraying spots, the spraying effect is low in areas where the spray rate is small, and the alkali concentration is high in areas where the spray rate is high, which may cause phytotoxicity to agricultural products.
Moreover, since the slaked lime after application | coating is water-soluble, it melt | dissolves easily by rainfall, it osmose | permeates in the soil, and an effect may lose | disappear early.
これらの欠点を改良し、しかも、散布後の崩壊性を改良する目的で、豆腐製造後に発生するおからを乾燥させ、この乾燥おからと消石灰を混合して数ミリの大きさの粒子とすることも提案されている。（特許文献１）
このような提案によれば、確かに散布性や崩壊性は改良されるものの、食料用のおからを混合すると肥料のコストが高くなるなどの難点があった。
また、散布後に烏や鳩等の鳥類が残留するおからを食べ、病気を引き起こす等人道的な問題がある。
In order to improve these disadvantages and to improve the disintegration after spraying, the okara generated after tofu production is dried, and the dried okara and slaked lime are mixed to form particles of several millimeters in size. It has also been proposed. (Patent Document 1)
According to such a proposal, although dispersibility and disintegration are certainly improved, there is a problem that mixing fermented okara increases the cost of fertilizer.
In addition, there are humanitarian problems such as eating okara where birds such as cormorants and pigeons remain after spraying and causing disease.
籾殻と消石灰を混合して、高圧下で水蒸気処理することで、籾殻の吸水性を改良することも提案されている。（特許文献２）
しかし、この提案は、水産系廃棄物や下水汚泥等の高湿潤廃棄物の含水率を調整する水分調整材を得ることを目的としているため、アルカリ含有率が低く、農業用石灰肥料としては不向きである。
It has also been proposed to improve the water absorption of rice husk by mixing rice husk and slaked lime and steaming under high pressure. (Patent Document 2)
However, this proposal is aimed at obtaining a moisture adjusting material that adjusts the moisture content of highly humid waste such as marine waste and sewage sludge, so the alkali content is low and it is not suitable for agricultural lime fertilizer. It is.
本発明の目的は、農業用石灰肥料において、安価に製造できて、従来の消石灰肥料の欠点である散布性や飛散によるトラブルや、散布後の消石灰の早期溶解を遅延する消石灰混合物及びその製造方法を提供することである。 An object of the present invention is a slaked lime mixture that can be produced at low cost in agricultural lime fertilizer, delays the problem of sprayability and scattering, which are disadvantages of conventional slaked lime fertilizer, and early dissolution of slaked lime after spraying, and a method for producing the mixture Is to provide.

また、第２の発明は、籾殻及び／又は籾殻炭に消石灰水溶液を湿潤させ湿潤籾殻及び／又は籾殻炭とする第一段階と、該湿潤籾殻及び／又は籾殻炭に消石灰を混合する第二段階からなる上記に記載の消石灰混合物の製造方法である。
また、第３の発明は、籾殻に生石灰を混合し乾燥籾殻とする第一段階と、該乾燥籾殻に水を加えて湿潤籾殻とする第二段階と、該湿潤籾殻に消石灰を混合する第三段階からなる上記に記載の消石灰混合物の製造方法である。

得られた消石灰混合物は、消石灰の分離もなく、また水や消石灰塊等もなく散布に適していた。
この消石灰籾殻混合物を、畑に散布した後に数回の降雨があっても、籾殻に消石灰が付着して残っており、徐効性を有していることが観察された。
In the first and second inventions, the present embodiment shows an implementation in which a paste or the like is included in water for the purpose of improving the adhesion between rice husk and / or rice husk charcoal and slaked lime.
“As a first step, a slaked lime solution was prepared by dissolving 0.1 parts by weight of slaked lime (calcium hydroxide component ratio 96.7%) in 0.1 parts by weight of water and 0.1 parts by weight of starch as a paste. The slaked lime concentration of the slaked lime aqueous solution is 10% by weight.
In the same manner as in Example 1, a slaked lime rice husk mixture of the present invention was obtained.
The blending ratio of slaked lime to rice husk to water in this slaked lime rice husk mixture was 71% to 20% to 9%. The alkali component concentration of the slaked lime rice husk mixture was 68%, which sufficiently satisfied the standard of agricultural fertilizer defined by JAS.
The obtained slaked lime mixture was suitable for spraying without separation of slaked lime and without water or slaked lime mass.
It was observed that slaked lime remained attached to the rice husks even if there were several rains after the slaked lime rice husk mixture was sprayed on the field, and it had a slow effect.
本発明の消石灰混合物は、散布時の消石灰の飛散もなく、散布後も消石灰散布効果が長く持続することから、農業用石灰肥料として広く利用が可能である。 The slaked lime mixture of the present invention can be widely used as an agricultural lime fertilizer because slaked lime is not scattered at the time of spraying and the slaked lime spraying effect lasts long after spraying.
