Description
本発明は、きのこの人工栽培にしようする菌床培地の再生方法に関する。 The present invention relates to a method for regenerating a fungal bed medium used for artificial cultivation of mushrooms.
きのこ栽培用の菌床培地には、おが屑やコーンコブを主材として米ぬか等の養分を添加したものが使用されている。 As a fungus bed medium for mushroom cultivation, a material added with nutrients such as rice bran using sawdust and corn cob as a main material is used.
使用済みの菌床培地すなわち廃培地は、残留養分、死滅菌糸などの腐敗を惹起する成分を多く含むため、そのまま新たな菌床培地として利用することはできない。 A used microbial bed medium, that is, a waste medium, contains many components that cause spoilage such as residual nutrients and dead sterilized yarn, and thus cannot be used as it is as a new microbial bed medium.
また、廃培地に栄養分が残留しているので、肥料として利用することも検討されたが、醗酵によって悪臭を放ち、環境問題を惹き起こすおそれがある。 Further, since nutrients remain in the waste medium, use as a fertilizer has also been studied. However, there is a possibility that a malodor will be emitted by fermentation and cause environmental problems.
そして菌床培地を再生する方法としては、廃培地を攪拌しつつ熱風乾燥することが提案されている（例えば、特許文献１参照）が、より簡易で効率的な再生方法の実現が望まれている。 And as a method for regenerating the mycelium culture medium, it has been proposed to dry the hot medium while stirring the waste medium (see, for example, Patent Document 1), but it is desired to realize a simpler and more efficient regeneration method. Yes.
本発明は、使用済みの菌床培地を簡易かつ低コストに再生することができ、廃培地を有効に利用できて環境問題の解決に資することのできる再生方法を提供することを目的としている。 An object of the present invention is to provide a regeneration method that can regenerate a used microbial bed medium easily and at low cost, and can effectively use a waste medium and contribute to solving environmental problems.
上記課題を解決するために、本発明に係る菌床培地の再生方法は、使用済みのきのこの菌床培地である廃培地を、所要時間水に浸すか蒸気に晒して廃培地中の残留養分やその他のきのこ生育時における生成物質を溶出させ、その後廃培地の水分調整を行うとともに新たに栄養分を加えて攪拌し、熱による乾燥を行うことなく再生培地を得ることを特徴としている。
In order to solve the above-mentioned problems, the method for regenerating a fungus bed culture medium according to the present invention is a method for reusing a waste medium, which is a used mushroom bed culture medium, by immersing it in water for a required time or exposing it to steam to remove residual nutrients in the waste culture medium. and other eluted generating material during mushroom growing, then the moisture control of the waste medium line Utotomoni newly added nutrients stirring, is characterized by obtaining a regeneration medium without performing drying by heat.
また、前記再生培地を容器に入れた後、殺菌処理することを特徴としている。 In addition, the regeneration medium is put in a container and then sterilized.
さらに前記攪拌は、まず水分調整後の廃培地を攪拌してほぐし、その後栄養分を加えてさらに攪拌することを特徴としている。 Further, the stirring is characterized in that the waste medium after moisture adjustment is first stirred and loosened, and then nutrients are added and further stirred.
また、前記廃培地を水に浸すか蒸気に晒して廃培地を取り出した際に得られる廃水を、液肥として利用することを特徴としている。 Further, the waste water obtained when the waste culture medium is taken out by immersing the waste culture medium in water or by exposing it to steam is used as liquid fertilizer.
本発明の再生方法によれば、使用済みの培地（廃培地）を水に浸すか蒸気に晒すことにより、廃培地中の残留養分やその他のきのこ生育時における生成物質が水または蒸気に溶出させられる。 According to the regeneration method of the present invention, the spent nutrient medium (waste medium) is immersed in water or exposed to steam, so that residual nutrients in the waste medium and other products generated during mushroom growth are eluted into water or steam. It is done.
そして、余分な物質が排出された廃培地を攪拌することによって廃培地中の菌糸が切断されて菌糸による廃培地の塊がほぐされ、リフレッシュされる。 Then, by stirring the waste medium from which excess substances are discharged, the mycelium in the waste medium is cut, and the lump of the waste medium by the mycelia is loosened and refreshed.
このリフレッシュされた廃培地に所要の栄養分を加えてさらに攪拌することによって、再生培地が得られ、この再生培地は未使用の培地と同様に生育瓶に入れて使用することができる。 A regenerated medium can be obtained by adding necessary nutrients to the refreshed waste medium and further stirring, and this regenerated medium can be used in a growth bottle in the same manner as an unused medium.
したがって、本発明の再生方法の過程における排出物は廃培地を水に漬けたり蒸気に晒したりした際の廃水だけであり、しかもこの廃水は廃培地中に残留していた余剰の養分を含む液肥として、果樹や野菜などの他の農作物の育成に利用することができる。 Therefore, the waste discharged in the process of the regeneration method of the present invention is only waste water when the waste medium is immersed in water or exposed to steam, and this waste water contains liquid nutrients containing excess nutrients remaining in the waste medium. As such, it can be used to grow other crops such as fruit trees and vegetables.
すなわち、廃棄物を出さずに済むという環境問題の解消に資することが可能な再生方法を実現できる。 That is, it is possible to realize a recycling method that can contribute to the solution of the environmental problem of eliminating waste.
また、廃培地を熱風などの熱で乾燥させる手段によって再生を図る従来の技術のように、再生のための特殊な装置を使う必要がなく、また大なる熱エネルギーの消費も必要とせず、したがって低コストに廃培地の再生を行うことができる。 Further, unlike the conventional technology for regenerating waste medium by means of drying with heat such as hot air, it is not necessary to use a special device for regeneration, and it is not necessary to consume a large amount of heat energy. The waste medium can be regenerated at low cost.
以下、本発明方法の実施例について説明する。
きのこを収穫した後の育成瓶から使用済みの菌床培地（廃培地）を取り出し、６０℃の水（湯）に２時間浸す。
Examples of the method of the present invention will be described below.
The used microbial bed medium (waste medium) is taken out from the growth bottle after harvesting the mushrooms and immersed in water (hot water) at 60 ° C. for 2 hours.
水に浸し終えた廃培地を、通水性を有するネット等のろ過部材上に載せて１時間静置し、余剰水分を排出させる。 The waste medium that has been immersed in water is placed on a filtration member such as a water-permeable net and allowed to stand for 1 hour to discharge excess water.
余剰水分を排出させた廃培地をミキサーに入れて攪拌し、廃培地中の菌糸による塊をほぐし、その後所要の栄養分、例えば米ぬか等をミキサー内に入れてさらに攪拌する。
この際、必要に応じて新たなおが屑やコーンコブを加える場合もある。
The waste medium from which excess water has been discharged is placed in a mixer and stirred to loosen the lump of the mycelium in the waste medium, and then the necessary nutrients such as rice bran are placed in the mixer and further stirred.
At this time, new sawdust and corn cob may be added as necessary.
その後、未使用のものの基準に準じてきのこの生育に適した水分量に調整し、生育瓶に詰め、適宜の殺菌処理を行って新たなきのこの栽培に供する。 Then, it adjusts to the moisture content suitable for this growth according to the standard of an unused thing, stuffs in a growth bottle, performs an appropriate disinfection process, and uses for new mushroom cultivation.
上述の方法において、廃培地を浸すのに使用した水およびろ過部材によって排出させた余剰水分は、廃培地中の余剰養分を含んでいるので、果樹や野菜の生育用の液肥として、従来から用いられる化学肥料や堆肥と同様に安全に使用することができる。 In the above method, the water used to immerse the waste medium and the excess water discharged by the filtration member include surplus nutrients in the waste medium, so that it has been conventionally used as a liquid fertilizer for growing fruit trees and vegetables. It can be used safely as well as chemical fertilizer and compost.
本実施例においては、廃培地を６０℃の水に浸す例について説明したが、水の温度は栽培対象となるきのこの種類や周囲の温度、使用した養分の種類等の諸条件によって適宜設定すればよく、６０℃に限定されるものではない。 In the present embodiment, an example in which the waste medium is immersed in water at 60 ° C. has been described, but the temperature of the water is appropriately set according to various conditions such as the type of mushrooms to be cultivated, the ambient temperature, and the type of nutrient used. The temperature is not limited to 60 ° C.
また、水に浸す工程に代えて蒸気に晒すことによっても同様の作用、効果を得ることができ、蒸気の温度および圧力についても水に浸す場合と同様に諸条件に応じて適宜設定する。 Further, the same action and effect can be obtained by exposing to steam instead of the step of immersing in water, and the temperature and pressure of the steam are appropriately set according to various conditions as in the case of immersing in water.
