Description
本発明は、野菜などの植物の輪作および連作の組合せを判定する方法に関し、特に、アレロパシー物質を放出する可能性のある植物の後作に適した植物を選定するのに水耕栽培を用いる後作植物判定方法、および、当該方法を適用した植物の連続栽培方法に関する。 The present invention relates to a method for determining the combination of rotation and continuous cropping of plants such as vegetables, and in particular after using hydroponics to select suitable plants for subsequent crops that may release allelopathic substances. The present invention relates to a method for determining plant production and a continuous cultivation method for plants to which the method is applied.
植物を同じ場所で栽培すると、種類によっては生育不良いわゆる連作障害を起こし、生産効率が低下してしまうものがある。連作障害の一因は、植物が放出したアレロパシー物質が自身に対する生育抑制物質として働き、自家中毒を起こすためである。この連作障害を回避するため、異なる種類の植物を栽培していく輪作が一般的に行われている。 When a plant is cultivated in the same place, depending on the type, there is a growth failure, so-called continuous cropping failure, and the production efficiency decreases. One cause of continuous cropping disorders is that allelopathic substances released by plants act as growth-inhibiting substances for themselves and cause self-poisoning. In order to avoid this continuous cropping failure, rotations in which different types of plants are cultivated are generally performed.
また、輪作は、年間を通じて農地を利用することもできるので、土地の利用効率を向上させるために行われる場合もある。 In addition, crop rotation can be used throughout the year, so it can be used to improve land use efficiency.
しかしながら、従来の技術では以下の問題点があった。
すなわち、輪作を行ったとしても、植物の組合せによっては、前作に用いた植物のアレロパシー物質が、後作に用いる植物の生育抑制物質として働き、後作の生産効率が低下してしまうという問題点があった。
However, the conventional technique has the following problems.
In other words, even if a crop rotation is performed, depending on the combination of plants, the allelopathic substance of the plant used in the previous crop works as a growth inhibitory substance for the plant used in the subsequent crop, and the production efficiency of the subsequent crop is reduced. was there.
このため、栽培者は、輪作を行うに際しては後作に適した植物を選定する必要があった。しかしながら、この選定は栽培者の感と経験に頼るところが大きく、実際に栽培してみなければわからないのが実情である。したがって、後作に用いる植物の選定には、多大な時間と労力がかかるという問題点があった。 For this reason, the grower has to select a plant suitable for the succeeding crop when performing the rotation. However, this selection largely depends on the grower's feelings and experience, and the fact is that it cannot be understood unless it is actually grown. Therefore, there has been a problem that it takes a lot of time and labor to select a plant to be used for the succeeding crop.
また、上述した輪作でなくとも、外国品種や新品種など栽培実績のない植物を連作しようとする場合、アレロパシー物質による自家中毒を起こすかどうかを確認するには、やはり実際に栽培してみなければならず、輪作の植物選定と同様の問題点が生じていた。 Even if it is not the above-mentioned rotation, if you are trying to continuously produce plants that have not been cultivated, such as foreign varieties and new varieties, you can still cultivate them to see if you will cause self-poisoning by allelopathic substances. As a result, problems similar to the selection of plants for crop rotation occurred.
本発明は上記に鑑みてなされたものであって、アレロパシー物質を放出する可能性のある植物の後作に適した植物を、短期間で簡易に選定することができる後作植物判定方法を提供することを目的とする。 The present invention has been made in view of the above, and provides a succeeding plant determination method capable of easily selecting a plant suitable for a succeeding plant that may release an allelopathic substance in a short period of time.

Hereinafter, embodiments of the present invention will be described in detail.
In this example, a state in which a plant suitable for a succeeding crop of asparagus “welcome” is selected using the succeeding crop determining method of the present invention will be described. The following 15 varieties of plants were used as candidate plants.
Asparagus: Welcome cucumber: Summer Suzumi, Antarctic No. 1 soybean: Summer voice, Sayamusume, Tankuro lettuce: Chateau cabbage: Early ball, green ball Souzuki, Teruyoshi, Wakamine Hakusai: Yuhuang, Yellow Koro 365, Daifuku Astor : Stella Rose
先ず、園試処方７５％標準液（電気伝導度ＥＣ ２．０ｄＳ／ｍ）を用いてアスパラガス「ウェルカム」の水耕栽培を行った。この園試処方７５％標準液を培養液Ａとする。次に、アスパラガス「ウェルカム」を水耕栽培した後の培養残液を採取し、養分となる窒素、リン、カリウム、カルシウム、マグネシウム、鉄を培養液Ａと同じ濃度に調整し判定用培養液Ｂとした。さらに、この判定用培養液Ｂを活性炭（味の素ファインテクノ株式会社製 粒状 Ｙ−４Ｐ）に通して判定用培養液Ｃとした。 First, hydroponic cultivation of asparagus “Welcome” was performed using a garden test prescription 75% standard solution (electric conductivity EC 2.0 dS / m). This garden trial prescription 75% standard solution is designated as culture solution A. Next, the culture residual liquid after hydroponically cultivating asparagus “Welcome” is collected, and nitrogen, phosphorus, potassium, calcium, magnesium, and iron serving as nutrients are adjusted to the same concentration as the culture liquid A, and the determination culture liquid B. Furthermore, this culture medium for determination B was passed through activated carbon (granular Y-4P manufactured by Ajinomoto Fine Techno Co., Ltd.) to obtain a culture medium C for determination.
培養液Ａ、判定用培養液Ｂ、判定用培養液Ｃをそれぞれ別々のコンテナ（容量約４リットル）に３リットルずつ入れ、１コンテナ当り１０株の候補植物の苗を移植し、３週間栽培を行った。３週間後各植物の水面より上部の生体重を測定し、生育状態の比較検討を行った。生体重の測定結果は表１の通りである。
培養液Ａと判定用培養液Ｂとを比較すると、キュウリ「夏すずみ」（要確認）「南極１号」、ダイズ「夏の声」「サヤムスメ」、レタス「シャトー」、キャベツ「アーリーボール」については、判定培養液Ｂを用いても生育の抑制がほとんど見られなかった。したがって、これらの植物は、アスパラガス「ウェルカム」の後作に適した植物と判定することができる。特に、レタス「シャトー」、キャベツ「アーリーボール」については、判定用培養液Ｂを用いた場合生育の促進が見られ、アスパラガスの後作により適した植物と判定することができる。 Comparing culture broth A with culture broth B for judgment, cucumber “Natsuzumi” (requires confirmation) “Antarctic No. 1”, soybean “summer voice” “Sayamusume”, lettuce “Chateau”, cabbage “Early Ball” No growth suppression was observed even when the determination culture solution B was used. Therefore, these plants can be determined as plants suitable for the succeeding crop of asparagus “welcome”. In particular, for the lettuce “Chateau” and the cabbage “Early Ball”, when the culture medium for determination B is used, growth is promoted, and it can be determined that the plant is more suitable for the succeeding crop of asparagus.
また、培養液Ａと判定用培養液Ｂとを比較すると、アスパラガス「ウェルカム」、キャベツ「グリーンボール爽月」、ハクサイ「黄ごころ３６５」「大福」、アスター「ステラ・ローズ」については、判定用培養液Ｂを用いた場合、生育の抑制が見られた。しかしながら、これら５種類の植物について培養液Ａと判定用培養液Ｃとを比較すると、判定用培養液Ｃを用いた場合生育の抑制が見られなかった。したがって、これらの植物は、土壌または培養液への活性炭の添加により栽培が可能となる植物と判定することができる。 In addition, when the culture medium A and the culture medium B for judgment are compared, the judgment is made for asparagus “Welcome”, cabbage “Green Ball Souzuki”, Chinese cabbage “Yellow Roll 365” “Daifuku”, and Aster “Stella Rose”. When culture broth B was used, growth suppression was observed. However, when the culture broth A and the culture broth C for determination were compared for these five types of plants, no growth suppression was observed when the culture broth C for determination was used. Therefore, these plants can be determined as plants that can be cultivated by adding activated carbon to the soil or culture solution.
同様に、培養液Ａと判定用培養液Ｂとを、培養液Ａと判定用培養液Ｃとをそれぞれ比較すると、ダイズ「たんくろう」、キャベツ「輝吉」「若峰」、ハクサイ「優黄」については、判定用培養液Ｂ、判定培養液Ｃいずれを用いた場合も生育の抑制が見られた。したがって、これらの植物は、アスパラガス「ウェルカム」の後作に適さない植物と判定することができる。 Similarly, when the culture broth A and the culture broth B for judgment are compared with the culture broth A and the culture broth C for judgment, respectively, soybean "Tankurou", cabbage "Terukichi" "Wakamine", Chinese cabbage "Yu Huang" As for, growth suppression was observed when either of the determination medium B and the determination medium C was used. Therefore, these plants can be determined as plants that are not suitable for the succeeding crop of asparagus “welcome”.
なお、上述の実施の形態では、判定用培養液Ｂを生成するのに、アスパラガス「ウェルカム」一種類を栽培して培養残液を採取したが、本発明はこれに限定されるものではない。例えば、複数種類の植物、植物ａ、植物ｂ、植物ｃ、を順次栽培した後の後作に用いる植物を選定する場合には、実際に栽培するのと同様の順番で植物ａ〜植物ｃを水耕栽培し、残液を採取して判定用培養液を生成してもよい。また、上述の実施の形態では、判定用培養液Ｃを生成する際、養分濃度の調整を行った後で培養液を活性炭に通したが、濃度調整の前に活性炭へ通してもよい。また、前作に用いる植物および候補植物は、上述した野菜や花卉に限るものでなく、果樹などの植物であってもよい。 In the above-described embodiment, in order to generate the determination culture solution B, one kind of asparagus “welcome” is cultivated and the culture residual solution is collected. However, the present invention is not limited to this. . For example, when selecting a plant to be used for a succeeding crop after sequentially cultivating a plurality of types of plants, plant a, plant b, and plant c, plant a to plant c in the same order as they are actually grown. Hydroponic cultivation may be performed, and the residual liquid may be collected to produce a determination culture liquid. Moreover, in the above-mentioned embodiment, when producing the culture solution C for determination, the culture solution is passed through activated carbon after adjusting the nutrient concentration, but it may be passed through activated carbon before adjusting the concentration. Further, the plants and candidate plants used in the previous crop are not limited to the above-mentioned vegetables and flower buds, and may be plants such as fruit trees.
本発明を利用して水耕栽培による輪作や連作を評価可能となる。
Utilizing the present invention, it becomes possible to evaluate rotation and continuous cropping by hydroponics.
