Description

本発明は、土壌の施肥と消毒とを兼ねる地中埋設型施肥兼用土壌消毒用ホースに関する。   The present invention relates to an underground buried fertilizer and soil disinfection hose that combines soil fertilization and disinfection.

従来、野菜、花又は果実などの栽培土壌に発生する害虫を殺傷して栽培土壌を消毒するために、臭化メチルが用いられていた。しかしながら、この臭化メチルによる消毒方法は、地球環境に対して悪影響を及ぼすことが判明しており、問題視されている。   Conventionally, methyl bromide has been used to kill insect pests generated in cultivated soil such as vegetables, flowers or fruits and disinfect the cultivated soil. However, this disinfection method using methyl bromide has been found to have an adverse effect on the global environment, and is regarded as a problem.

そこで、近年では、栽培土壌の土中にホースを敷設(埋設)し、このホースから高温・高圧の水蒸気を放出させて土壌を消毒する方法が提案されている。
この方法では、土壌温度を検出する温度検出機構を設け、その温度検出機構による検出情報に基づいて、消毒もれや過剰過熱を生じさせないようにボイラによる適宜な蒸気供給を行っている。(例えば、特許文献1参照)。
Therefore, in recent years, a method has been proposed in which a hose is laid (buried) in the soil of the cultivated soil, and high-temperature and high-pressure steam is released from the hose to disinfect the soil.
In this method, a temperature detection mechanism for detecting the soil temperature is provided, and appropriate steam supply is performed by a boiler so as not to cause disinfection leakage or excessive overheating based on detection information by the temperature detection mechanism. (For example, refer to Patent Document 1).

また、注入、土壌浄化、水質調査等で土中に埋設させたパイプを、その使用後に掘り起こしたり引き抜いたりして産業廃棄物として処理することなく、埋設させたまま、そのパイプに微生物が有効成分となる材料を注入または充填し、微生物によってパイプを土中内で分解させる方法が提案されている。(例えば、特許文献2参照)。   In addition, pipes embedded in soil for injection, soil purification, water quality surveys, etc., are digged up or pulled out after use and treated as industrial waste without being treated as industrial waste. A method has been proposed in which a material to be injected is injected or filled, and a pipe is decomposed in soil by microorganisms. (For example, refer to Patent Document 2).

また、農作物や園芸作物に対して被害を与える害生物を防除する防除材を使用後に、その防除材を特許文献2と同様に土中から回収せずにそのまま放置して、自然界に存在する微生物により分解させて、産業廃棄物として処理することなく環境汚染を引き起こすことの無い高分子素材の防除材を使用する方法が提案されている。(例えば、特許文献3参照)。

In addition, after using a control material that controls pests that damage agricultural crops and horticultural crops, the control material is left as it is without being recovered from the soil as in Patent Document 2, and microorganisms that exist in nature There has been proposed a method of using a polymer material control material that does not cause environmental pollution without being decomposed by the above method and treated as industrial waste. (For example, refer to Patent Document 3).

しかしながら、特許文献1の方法では、消毒後に蒸気放出ホースの回収を行う作業が生じていた。この消毒後のホースを回収する作業は、最低2名の作業者を必要とするので、手数が掛かるだけでなく人件費も掛かって使用者側の利便性を損ねるものであった。   However, in the method of Patent Document 1, an operation of collecting the steam discharge hose after disinfection has occurred. The operation of collecting the hose after sterilization requires a minimum of two workers, which is not only troublesome but also costs labor and impairs the convenience on the user side.

また、特許文献1のシステムを販売する際に行う宣伝・紹介のための実演では、最低3名以上の人員が必要であり、やはり手数が掛かるだけでなく人件費も掛かって供給者側の利便性をも損ねるものであった。   In addition, the demonstration for the promotion / introduction performed when selling the system of Patent Document 1 requires at least three personnel, which is not only labor intensive but also labor costs, and is convenient for the supplier. It was also detrimental to sex.

また、特許文献2では、特許文献1のように、使用後の管の回収を行わず、土中に埋設させた状態で管に微生物が有効成分となる材料を注入または充填させて管を土中内で分解させているが、管に微生物が有効成分となる材料を注入または充填させる作業は、特許文献1と同様に最低2名の作業者が必要であり、作業に従事する者の利便性を損ねる点において変わるところはなかった。   Also, in Patent Document 2, as in Patent Document 1, the pipe after use is not collected, but the pipe is filled with a material in which microorganisms become active ingredients while being buried in the soil, and the pipe is filled with the soil. Although it is decomposed in the inside, the work of injecting or filling the material in which the microbe is an active ingredient into the tube requires at least two workers as in Patent Document 1, and is convenient for the person engaged in the work. There was no change in the point of damaging sex.

また、特許文献3では、特許文献1及び特許文献2において問題となる作業従事者の利便性を損ねる点は解消されているが、特許文献3で取り上げている防除材は、ボイラ装置から蒸気の供給を行うものではない。   Moreover, in patent document 3, although the point which impairs the convenience of the worker who becomes a problem in patent document 1 and patent document 2 is eliminated, the control material currently taken up in patent document 3 is a vapor | steam from a boiler apparatus. It does not supply.

本発明の課題は、上記従来の実状に鑑み、土壌を消毒するため高温・高圧の蒸気を使用し、土壌中に埋設した蒸気放出ホースで土壌を消毒した後、その蒸気放出ホースを土中に放置でき且つそのホースの自然分解後の成分を有機肥料として活用できる地中埋設型施肥兼用土壌消毒用ホースを提供することである。   In view of the above-described conventional situation, the object of the present invention is to use high-temperature and high-pressure steam to disinfect soil, disinfect the soil with a steam discharge hose embedded in the soil, and then dispose the steam discharge hose in the soil.

It is convenient for the supplier of soil disinfection and soil disinfection hose to easily perform demonstrations for advertisement and introduction.

以下、図面を参照しながら本発明の実施の形態について説明する。
図1は一実施の形態における地中埋設型施肥兼用土壌消毒用ホース(以下、蒸気放出ホースともいう)1を敷設した栽培土壌2の平面図である。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of cultivated soil 2 in which an underground buried fertilizer / soil disinfection hose (hereinafter also referred to as a steam release hose) 1 is laid in one embodiment.

尚、図1では、蒸気放出ホース1を横方向、縦方向、横方向、・・・と連続して向きを変えながら敷設しているが、これに限ることなく、例えば、斜め方向に折り返しながら敷設するようにしても良い。   In addition, in FIG. 1, although the vapor | steam discharge hose 1 is laid, changing direction continuously with a horizontal direction, a vertical direction, a horizontal direction, ..., it is not restricted to this, For example, You may make it lay.

この蒸気放出ホース1は、例えば野菜や花などの栽培土壌に埋設させて用いるものであり、この蒸気放出ホース1には、無数の孔が形成されている。この孔は、蒸気放出ホース1に接続させたボイラ装置3から供給される高温・高圧の蒸気を土壌内に放出するために形成されている。   The steam release hose 1 is used by being embedded in cultivated soil such as vegetables and flowers, and the steam release hose 1 has numerous holes. This hole is formed in order to discharge the high-temperature and high-pressure steam supplied from the boiler device 3 connected to the steam discharge hose 1 into the soil.

尚、蒸気放出ホース1を、帯状の基布を縦に縫い付けて形成した場合には、縫い目から
高圧蒸気を放出することができるので、蒸気放出用の無数の孔を形成する必要がない。
また、この蒸気放出ホース1を埋設した箇所には、蒸気放出ホース1から放出される高温・高圧の蒸気による高温度が土壌内部から外部に逃げないように、保湿シート4が覆うように設けられている。
In addition, when the vapor | steam discharge hose 1 is formed by sewing a strip | belt-shaped base fabric vertically, since a high voltage | pressure vapor | steam can be discharge | released from a seam, it is not necessary to form innumerable holes for vapor | steam discharge | release.
Further, at the place where the vapor discharge hose 1 is embedded, a moisture retention sheet 4 is provided so as to prevent the high temperature due to the high temperature and high pressure vapor discharged from the vapor discharge hose 1 from escaping from the inside of the soil to the outside. ing.

また、この蒸気放出ホース1は不織布で形成されている。この不織布は土壌菌により分解させることができる素材で作製されている。
これにより、蒸気放出ホース1は土壌を消毒した後に土壌内に放置しておくと、土壌菌により分解させることができるので、この蒸気放出ホース1を土壌内から掘り起こして撤去する作業を省くことができ、蒸気放出ホース1の施設に伴う使用後の撤去作業が解消されて作業全体が簡便化して便利である。
Moreover, this vapor | steam discharge hose 1 is formed with the nonwoven fabric. This nonwoven fabric is made of a material that can be decomposed by soil bacteria.
As a result, if the steam release hose 1 is sterilized and left in the soil, it can be decomposed by soil bacteria, so that the work of digging up and removing the steam release hose 1 from the soil can be omitted. The removal work after use accompanying the facility of the steam discharge hose 1 is eliminated, and the whole work is simplified and convenient.

また、蒸気放出ホース1を形成している不織布には、内部または表層部に、肥料の三大元素である窒素、リン酸、カリウムの一つ以上が予め付加されている。これらの肥料成分は、蒸気放出ホース1が土壌内で土壌菌により自然分解した際に、肥料として用いられる。 Further, the nonwoven fabric forming the vapor release hose 1 is preliminarily added with one or more of three major elements of fertilizer, nitrogen, phosphoric acid, and potassium, inside or on the surface layer. These fertilizer components are used as fertilizer when the vapor release hose 1 is naturally decomposed by soil fungi in the soil.

図2は、図1のA−A´矢視断面図である。栽培土壌2に敷設された蒸気放出ホース1に土を覆い、盛り土部5を形成させる。この盛り土部5を保湿シート4で更に覆い、この保湿シート4の縁部分に鎖、鉄棒などからなる載置具6a、6bを載置し、保湿シート4がめくりあがらないようにする。   FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG.
