Description

本発明は植物栽培用培地の種類、利用法に関し詳細には野菜等の成育過程で大気圧を利用した極めて簡単な方法でかつ任意の間隔で培地内全体の気孔空隙内空気(酸素)を入替え、肥料成分坑菌成分殺虫成分等を含有する栽培溶液をよどみ無く培地内全体全てに均等に周期的定時間毎に供給する事の出来る培地及び方法に関する
[背景技術]
The present invention relates to the type and use of a plant cultivation medium. In particular, the air in the pore space (oxygen) in the whole medium is replaced at an arbitrary interval by an extremely simple method using atmospheric pressure in the growth process of vegetables and the like. [Background Art] The present invention relates to a culture medium and method capable of supplying a cultivation solution containing fertilizer components, antibacterial components, insecticidal components, etc., without any stagnation to the entire medium evenly at regular intervals.

野菜等の水耕栽培はガラス繊維、セラミック繊維、ロックウ−ル等の人造鉱物繊維を色々な立方体に成型し栽培培地として栽培槽に収納し肥料成分等を含有した溶液に漬けて用いているだけで栽培期間の間に培地の気孔空隙内の空気の完全な入替え、培地に吸われている栽培溶液の完全な入替えを行う培地の使用態様は想定されておらず培地内の“よどみ”の発生を防ぐ事は行われていない。
[発明の開示]
[発明が解決しようとする課題]
Hydroponic cultivation of vegetables, etc., is made by molding artificial mineral fibers such as glass fibers, ceramic fibers, rock wool, etc. into various cubes, storing them in a cultivation tank as a cultivation medium, and immersing them in a solution containing fertilizer components etc. During the cultivation period, it is not assumed that the medium is used for complete replacement of air in the pore space of the medium, and complete replacement of the cultivation solution sucked by the medium. Occurrence of “stagnation” in the medium It is not done to prevent.
[Disclosure of the Invention]
[Problems to be solved by the invention]

水耕栽培は資料1の様に水溶液を作物の成育段階に応じた周期的時間毎ごと、培地にかけ流し又は点滴的方法で培地に滴下した後、受水槽に回収し再使用又は培地を栽培槽に水没状態にし栽培槽内の溶液を循環する方法が一般的であるがこれらの方法では培地内に張出す根群イコ−ル、つまり培地に対して均等に新鮮な空気を供給する事は不可能であり、肥料成分等についても不可能であった。つまり点滴的に滴下された肥料成分等を含んだ溶液は立方体培地の上部、ある点に滴下された後この点を頂点に放射状かつ垂直的に培地内を垂れ下がって行き、培地よりしみでてかけ流れるか再び集められまた循環する。つまりこの放射状かつ垂直的部分にカバ−される部分は常に新鮮な空気、養水分で満たされるがこれを外れた部分については肥料成分等については浸透圧でわずかに移動するだけであり空気にかんしては移動できず少しづつ よどん で来て病害発生の基と成る事がある。培地内に進んで行く根群エリアと滴下点を頂点とする放射状かつ垂直的部分エリアを合致させる事は現状の方法では不可能である。例えて更にわかり易く説明すれば水を飽水(飽和)状態に含んだスポンジをゆるく流れる肥料成分等を含んだ水流に入れてもスポンジ内の水と水流を入替える事はスポンジの表面しか出来ない。全部を入替えるにはスポンジを水流から上げて、手で握って搾る事で水が逃出し、手を開けばスポンジは元のかたちに戻り同時に隙間なく新鮮な空気が万遍無く行渡り、そして水流中に戻せば気孔空隙内空気は溶液と入替わり肥料成分等が万遍無く均等にスポンジへ、つまり培地に行渡る。本発明の課題は水耕栽培に於いて今まで出来なかった上述したスポンジの例の如くを極めて簡単な方法で水耕栽培に用いられている人造鉱物繊維に応用する事であり培地内に よどみ 部を生じさせないで培地内全体に隙間なく根群を張り渡す栽培方法を提供することにある。
[課題を解決するための手段]
Hydroponics is the same as in Document 1 in which the aqueous solution is poured over the medium every period of time according to the growth stage of the crop or dripped onto the medium by a drip method, and then collected in the water receiving tank and reused or the medium is grown. However, it is not possible to circulate the solution in the cultivation tank in a submerged state, but in these methods it is not possible to supply fresh air evenly to the root group equal to the root group that extends into the medium. It was possible, and it was impossible for fertilizer components. In other words, the solution containing fertilizer components dripped in drops is dripped onto the top of the cubic culture medium at a certain point, and then hangs down in the medium radially and vertically with this point as the apex. Flow or collect again and circulate again. In other words, the part covered by this radial and vertical part is always filled with fresh air and moisture, but the part outside this part moves only slightly due to osmotic pressure for fertilizer components, etc. It is difficult to move, and it may gradually come and gradually become the basis for the occurrence of disease. It is impossible with the current method to match the root group area going into the culture medium with the radial and vertical partial area with the dropping point as the apex. For example, even more easily explained, even if the sponge containing water is saturated (saturated) and put into a water stream containing a fertilizer component that flows loosely, only the surface of the sponge can be exchanged with the water in the sponge. . To replace everything, raise the sponge from the water flow, squeeze it with your hand, the water escapes, and if you open your hand, the sponge will return to its original shape and at the same time, fresh air will pass through without any gaps. When returned to the water flow, the air in the pore space is replaced with the solution, and the fertilizer components and the like are evenly distributed to the sponge, that is, the medium. The object of the present invention is to apply to the artificial mineral fiber used for hydroponics by an extremely simple method, such as the example of the sponge described above, which has not been possible until now in hydroponics. An object of the present invention is to provide a cultivation method in which roots are stretched without any gaps throughout the medium without producing any part.
[Means for solving problems]

上記課題を解決する為請求項記載の植物栽培方法は栽培槽の溶液の全排水、満水を交互に周期的に繰返し行う事で培地に対して「乾」と「湿」を与える事である。ここで言う「乾」とは培地の気孔空隙内の溶液を排出すると言う意味でいわいる“湿り気”は含んでいる状態で乾燥させる事ではない。「湿」とは培地を溶液に水没させると言う意味でいわいる“湿らがす”と言う事ではない。
人造鉱物繊維による培地に対しての本発明の理解をわかり易くする為に100%合致する物ではないが身近な本発明の代用材培地例として籾殻を例として説明すると籾殻は水田等の暗渠土管の埋設材に用いられている様に溌水性透水性を有し適度な気孔空隙を備え、従来用いられている水耕栽培用培地の様に溶液にどぶ漬けにしても、溶液を排水すれば飽水(飽和)状態となる事は無く、気孔空隙に大気圧により新鮮な空気を呼込む事ができる。また籾殻は有機物なので栽培終了後野外に出して置けばたい肥とする事もできるし籾殻の野焼きが禁止され稲作農家は籾殻の処分に苦慮している現状であり無尽蔵に産出されるただ同然の材料であり前にも述べたけれど100%本発明に合致するものではないが後で述べる実施例によりギリギリ利用可能な一副材料である。
[発明の効果]
In order to solve the above-mentioned problems, the plant cultivation method described in the claims is to give “dry” and “wet” to the culture medium by periodically repeating all drainage and full water of the solution in the cultivation tank alternately. The term “dry” as used herein does not mean that “wet”, which means that the solution in the pore space of the medium is discharged, is dried in a state where it is contained. “Wet” does not mean “wet” in the sense that the medium is submerged in the solution.
In order to make the understanding of the present invention for artificial mineral fibers easier to understand, the rice husk is an example of a familiar substitute medium of the present invention that is not 100% consistent. As it is used for buried materials, it has hydrophobic permeability and has an appropriate pore space, and even if it is immersed in a solution like a conventionally used culture medium for hydroponics, if the solution is drained, it will be saturated. There is no water (saturated) state, and fresh air can be drawn into the pore space by atmospheric pressure. In addition, rice husk is an organic material, so it can be made into fertilizer by putting it outdoors after cultivation, and rice burning is prohibited, and rice farmers are struggling to dispose of rice husk, and it is just an inexhaustible material However, it is one secondary material that can be used in the limit of the examples described later.
[The invention's effect]

本発明の植物栽培方法は人造鉱物繊維による培地の繊維の毛管作用等による高い呼水性、保水性がマイナス的に働く事を改良する作用効果を有する。また本発明の栽培法によれば栽培槽溶液の排水、満水を交互に行う事により今まで行なえなかった水耕栽培に於ける培地全域に新鮮な空気と栽培溶液を任意の間隔で給供する事ができ、根群を最適な成育環境で成育させる事が可能となる。
[発明を実施するための最良の形態]
The plant cultivation method of the present invention has the effect of improving the high water repellency and water retention due to the capillary action of the fibers of the medium with artificial mineral fibers. In addition, according to the cultivation method of the present invention, supply of fresh air and cultivation solution at arbitrary intervals to the entire medium in hydroponics that could not be performed until now by alternately draining and filling the cultivation tank solution. And roots can be grown in an optimal growth environment.
[Best Mode for Carrying Out the Invention]

本発明に用いる毛管作用を起こさない栽培培地は数種類上げる事ができるが人造鉱物繊維(ガラス繊維、セラミック繊維、ロックウ−ル)を綿菓子状態構造として各種立方体の形にして用いる事が主であり以下図面に基づき本発明の実施の形態を説明する。図1は本発明の一実施形態に係る培地の概要を示す斜視図である。図2は本発明の使用例を示す模式的斜視図である。毛管作用を起こさない為には人造鉱物繊維の成型密度を小さくする為に材料の種類にもよるけれど栽培槽の溶液を排水した場合につぶれてしまう事があるので栽培槽の内に培地をつぶれさせない為の架台を設けこの架台を挟むように培地を納める。当然の事ながら栽培する野菜類の植性、つまり良好な通気性を好む物、さほどでない物等それぞれに合った成型密度(気孔率)の培地を用いる事を実施の基本とする。
[実施例]
Although the cultivation medium which does not cause capillary action used in the present invention can be raised several types, it is mainly used in the form of various cubes as artificial candy fibers (glass fiber, ceramic fiber, rock wool) as a cotton candy state structure. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an outline of a culture medium according to an embodiment of the present invention. FIG. 2 is a schematic perspective view showing an example of use of the present invention. In order not to cause capillary action, depending on the type of material in order to reduce the molding density of artificial mineral fiber, it may collapse when draining the solution in the cultivation tank, so the medium in the cultivation tank is crushed Set up a pedestal to prevent it from being placed, and store the culture medium so as to sandwich the pedestal. As a matter of course, it is a basic practice to use a medium having a molding density (porosity) suitable for the plantability of vegetables to be cultivated, that is, those that favor good air permeability and those that do not so much.
[Example]

次に実施例により本発明を説明する。実施例では栽培槽の溶液の排出を早くする為に栽培槽底に多数穴の開いたパイプを栽培槽と同じ長さに設置し一端を吸込みポンプに接続し架台に乗せた受液槽に溶液を回収し、溶液の温度調整成分調整等を行った後栽培槽と架台の高低差を用いて培地上に渡した潅水チュ−ブ等で栽培槽を満水にする方法としたが本発明はこれらに制約されるものではなく栽培溶液の回収を急がない場合は栽培槽の底にバルブを設け自然落水する溶液を受水槽に回収する方法としても良いし、野菜成育の要素の1つである地温(培地温度)も栽培槽溶液の排水、満水の間隔を調整する事で容易に管理できる。また栽培槽内に架台を設ける程でもない成型密度の培地を好む野菜(植物等)の場合図4の様に栽培槽内に籾殻を収納し綿菓子状培地を籾殻で包み込み保持した綿菓子状培地上に野菜(植物等)の苗又は種を植え付ける方法も有効な利用法である。以上本発明のいくつかの実施形態に関して述べたが本発明は前述実施形態に制約されるものではなく、特許請求の範囲に記された範囲内で他の実施形態も実施可能である。例えば前述実施形態はハウス栽培での応用であるがこれに限らず露地栽培畑に於いて作物に適した幅、深さ、任意の畝長さの立方体穴を堀ビニ−ルを当てて槽を作り、槽の底にほぼ槽と同じ長さの多数穴の開いたパイプを置き吸込みポンプに接続した後、培地を満たせば露地栽培にも使用できる。また本発明を用いれば成育が良く管理が容易である為図3の様に鉢部を2槽とし下槽を受水槽、上槽を栽培槽とし野菜を観葉植物として用いる用途も拓く事ができる。  Next, an example explains the present invention. In the embodiment, in order to expedite the drainage of the solution in the cultivation tank, a pipe with a large number of holes at the bottom of the cultivation tank is installed to the same length as the cultivation tank, and one end is connected to a suction pump and placed in a liquid receiving tank placed on a stand After adjusting the temperature adjustment component of the solution, the cultivation tank was filled with a irrigation tube passed over the medium using the height difference between the cultivation tank and the gantry. If the collection of the cultivation solution is not urgent and there is no urgency, it is possible to provide a valve at the bottom of the cultivation tank and collect the solution that falls naturally into the water receiving tank, which is one of the elements of vegetable growth The soil temperature (medium temperature) can also be easily managed by adjusting the interval between drainage and full water of the cultivation tank solution. In the case of vegetables (plants, etc.) that prefer a medium with a molding density that is not enough to mount a stand in the cultivation tank, a cotton candy shape containing rice husks in the cultivation tank and wrapping and holding the cotton candy medium in the cultivation tank as shown in FIG. A method of planting seedlings or seeds of vegetables (plants, etc.) on the medium is also an effective usage. Although several embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and other embodiments can be implemented within the scope described in the claims. For example, the above-mentioned embodiment is an application in house cultivation, but is not limited to this. After making a pipe with a large number of holes almost the same length as the tank at the bottom of the tank and connecting it to the suction pump, it can be used for outdoor cultivation if the medium is filled. In addition, since the present invention is easy to grow and easy to manage, it is possible to open the use of potted plants as two tanks, lower tank as a receiving tank, upper tank as a cultivation tank, and vegetables as foliage plants as shown in FIG. .
