【実施例】この発明の実施例の詳細を以下に説明する。
この発明は、粉末肥料とパルプ細片を用意する。粉末肥
料は有機肥料であると化学肥料であることをを問わない
が、粉末状のものを用意する。粉末肥料は市販品を採用
したから、その大きさは一般的に−2m/m程度であ

紙スラッジを利用したから、これらは水分を一般的に5
5重量%程度を含んでいる。The details of embodiments of the present invention will be described below.
This invention provides powdered fertilizer and pulp shreds. Powdered fertilizer may be organic fertilizer or chemical fertilizer, but powdered fertilizer is prepared. Since a powdered fertilizer is a commercially available product, its size is generally about -2 m / m. On the other hand, since pulp sludge or papermaking sludge was used as the pulp strips, they generally contained 5% of water.
It contains about 5% by weight.
【0010】そこで、粉末肥料70重量%にパルプ細片
を30重量%を混合させ、水分を含んだままにより混練
機により、十分混練させる。Then, 30% by weight of pulp pieces are mixed with 70% by weight of powdered fertilizer and sufficiently kneaded by a kneader while containing water.
【0011】なお、この発明で採用したパルプ細片の大
きさはせいぜい数mm程度のおおきさであり、発明者は
百メッシュアンダーの大きさのものを実験的に試みた。The size of the pulp strip used in the present invention is at most about several millimeters, and the inventor experimentally tried a size of 100 mesh under.
【0012】次に成型機を介して押出成型させ、爾後処
理のために適当な形態に成形した。そして、その成型物
を使用の用途に応じて造粒工程を施し、ペレットを得
た。Next, it was extruded through a molding machine and molded into an appropriate form for post-treatment. Then, the molded product was subjected to a granulation step depending on the intended use to obtain pellets.
【0013】このペレットの大きさは発明者の実験によ
れば、一般的な形態としては1〜30mm程度の大きさ
により顆粒状や球状に加工するが、必ずしも顆粒状や球
状にに制限する趣旨ではなく、10mm程度の細長い柱
状であったり、ランダムな10mm程度のものであって
もよく、必要なことは土壌改良剤としての機能を奏する
ことである。According to experiments conducted by the inventor, the size of the pellets is generally processed into granules or spheres having a size of about 1 to 30 mm, but it is not limited to granules or spheres. Alternatively, it may have a long and narrow columnar shape of about 10 mm, or may have a random shape of about 10 mm, and what is necessary is to function as a soil conditioner.
【0014】次いで、ドライヤーによりそのペレットを
70〜300℃の温度により乾燥させる。Next, the pellets are dried by a dryer at a temperature of 70 to 300 ° C.
【0015】この場合、乾燥温度を70〜80℃程度の
比較的低温に制限して実施した場合には、植物の育成に
とって好ましい粉末肥料に含有される放線菌を死滅させ
ないで乾燥できる利点がある。In this case, when the drying temperature is limited to a relatively low temperature of about 70 to 80 ° C., there is an advantage that the actinomycetes contained in the powdered fertilizer, which is preferable for plant growth, can be dried without being killed. .
【0016】なお、この発明は土壌改良剤に関するもの
であるが、肥料についても商業的に利用できることは容
易に理解できるであろう。Although the present invention relates to a soil conditioner, it can be easily understood that a fertilizer can be used commercially.
【0017】[0017]
【発明の効果】この発明は上記の構成であるから、以下
の利点を奏する。 (1)土壌改良剤中に含まれるパルプ細片は水分の保持
能力が高いから、肥料が降雨により溶融してもその溶融
成分はパルプ細片中に保持される。したがって、従来降
雨により短期間に流出した肥料の成分が長期に亘って保
持されるため、保肥性の高い土壌改良剤が得られる。 (2)製紙工程中にアルカリ成分を供給して処理される
結果、パルプ細片中に含まれるそのアルカリ成分中の比
較的少量であるものの、カルシュウムウが含有している
ので結合剤の役割をするため、パルプ細片の有する粘性
と相待って粉末肥料とパルプ細片は確実に有機的に結合
され、分離することはない。 (3)パルプ細片が粉末肥料に結合される結果、従来粉
末肥料は粘性が高く、ポッパー内に収容させ、下方の開
放口から排出する場合、いわゆるブリッジが発生して落
下しないという問題があったが、パルプ細片を結合させ
た結果、顆粒状や球状のため粘性が軽減され、ブリッジ
が発生しない。Since the present invention has the above-mentioned structure, it has the following advantages. (1) Since the pulp particles contained in the soil conditioner have a high water retention capacity, even if the fertilizer is melted by rainfall, the molten component is retained in the pulp particles. Therefore, since the components of the fertilizer that have conventionally flown out in a short period due to rainfall are retained for a long period of time, a soil improving agent having high fertilizing properties can be obtained. (2) As a result of processing by supplying an alkaline component during the papermaking process, although it is a relatively small amount in the alkaline component contained in the pulp strip, since it is contained in calcium, it plays a role of a binder. Therefore, the powdered fertilizer and the pulp pieces are surely organically combined and do not separate, depending on the viscosity of the pulp pieces. (3) As a result of the pulp pieces being combined with the powdered fertilizer, the conventional powdered fertilizer has a high viscosity, and when it is stored in the popper and discharged from the lower opening, there is a problem that a so-called bridge does not occur and does not fall. However, as a result of combining the pulp pieces, the viscosity is reduced due to the granular or spherical shape, and the bridge does not occur.
