Description

本発明はプエラリア・ミリフィカの栽培方法に関し、特に寒冷地においても安定して栽培できるようにした方法に関する。   The present invention relates to a method for cultivating Pueraria mirifica, and more particularly to a method that enables stable cultivation even in cold regions.

プエラリア・ミリフィカ(Pueraria mirifica)はタイ国原産のマメ科植物であって、その根塊には特異なイソフラボノイド系物質が含有され、健康の増進と維持に効果があるとされている（特許文献１、特許文献２、特許文献３、特許文献４、特許文献５）。   Pueraria mirifica (Pueraria mirifica) is a leguminous plant native to Thailand, and its root nodules contain unique isoflavonoid substances and are said to be effective in promoting and maintaining health (Patent Literature) 1, Patent Document 2, Patent Document 3, Patent Document 4, Patent Document 5).

高齢者の人口が増加する現代にあっては、プエラリア・ミリフィカの各種薬用効果、特に若返り薬や長寿薬としての効能が期待されることから、プエラリア・ミリフィカの安定した供給が求められる。   In the present age when the population of the elderly is increasing, the stable supply of Pueraria Mirifica is required because of the expected medicinal effects of Pueraria Mirifica, especially as a rejuvenating and longevity drug.

特表２００３−５０８０４１号公報Japanese translation of PCT publication No. 2003-508041 特開２００１−３４８３３４号公報JP 2001-348334 A 特開２００１−２２０３４０号公報JP 2001-220340 A 特開２００１−１８１１７０号公報JP 2001-181170 A 特開２０００−３０２６６７号公報JP 2000-302667 A

しかし、プエラリア・ミリフィカは熱帯植物であり、栽培し得る地域が熱帯地域に限定され、わが国、特に寒冷地ではプエラリア・ミリフィカを露地栽培することができず、安定して入手することが難しかった。   However, Pueraria Mirifica is a tropical plant, and the area where it can be cultivated is limited to the tropical region. In Japan, particularly in cold regions, it was difficult to cultivate Pueraria Mirifica in the open field, making it difficult to obtain it stably.

本発明はかかる点に鑑み、寒冷地においても安定して栽培できるようにしたプエラリア・ミリフィカの栽培方法を提供することを課題とする。   This invention makes it a subject to provide the cultivation method of Pueraria mirifica which enabled it to cultivate stably also in a cold region in view of this point.

本件発明者らはプエラリア・ミリフィカの植物学的な特性について鋭意研究を重ねたところ、プエラリア・ミリフィカの栽培には温度、雨量及び土壌が重要であることを知見し、本発明を完成するに至った。   The present inventors have conducted extensive research on the botany characteristics of Pueraria Mirifica, and found that temperature, rainfall and soil are important for the cultivation of Pueraria Mirifica, and completed the present invention. It was.

本発明に係るプエラリア・ミリフィカの栽培方法は、プエラリア・ミリフィカを栽培するに当たり、プエラリア・ミリフィカの種子を酸処理又は熱処理する工程と、この種子を栽培土壌に移植し、この栽培土壌を５°Ｃないし４０°Ｃ、好ましくは１０°Ｃないし３０°Ｃの範囲内の温度に保持するとともに、上記栽培土壌の下方に水を供給することにより、プエラリア・ミリフィカの種子を発芽させ成長させる工程と、上記栽培土壌を５°Ｃないし４０°Ｃ、好ましくは１０°Ｃないし３０°Ｃの範囲内の温度に保持するとともに、上記栽培土壌の下方への水の供給を停止することにより、プエラリア・ミリフィカの根を肥大化させる工程と、を備えたことを特徴とする。   The method for cultivating Pueraria mirifica according to the present invention includes a step of acid-treating or heat-treating the seeds of pueraria mirifica, transplanting the seeds to cultivated soil, and cultivating the cultivated soil at 5 ° C. Sprouting and growing the seeds of Pueraria mirifica by keeping water at a temperature within the range of 40 ° C, preferably 10 ° C to 30 ° C, and supplying water below the cultivated soil; By maintaining the cultivated soil at a temperature in the range of 5 ° C to 40 ° C, preferably 10 ° C to 30 ° C, and stopping the supply of water below the cultivated soil, Pueraria Mirifica And a step of enlarging the roots of the plant.

また、本発明に係るプエラリア・ミリフィカの栽培方法は、プエラリア・ミリフィカを栽培するに当たり、プエラリア・ミリフィカの根塊、茎又は成長点を土壌床に活着させる工程と、活着した根塊、茎又は成長点を温室内の栽培土壌に移植し、この栽培土壌を５°Ｃないし４０°Ｃ、好ましくは１０°Ｃないし３０°Ｃの範囲内の温度に保持するとともに、上記栽培土壌の下方に水を供給することにより、プエラリア・ミリフィカを成長させる工程と、上記栽培土壌を５°Ｃないし４０°Ｃ、好ましくは１０°Ｃないし３０°Ｃの範囲内の温度に保持するとともに、上記栽培土壌の下方への水の供給を停止することにより、プエラリア・ミリフィカの根を肥大化させる工程と、を備えたことを特徴とする。   Further, the method for cultivating Pueraria Mirifica according to the present invention includes a step of cultivating the root mass, stem or growth point of Pueraria Mirifica on the soil floor, and the cultivated root mass, stem or growth. The point is transplanted to the cultivated soil in the greenhouse, and this cultivated soil is maintained at a temperature in the range of 5 ° C to 40 ° C, preferably 10 ° C to 30 ° C, and water is placed below the cultivated soil. Supplying the step of growing Pueraria Mirifica and maintaining the cultivated soil at a temperature in the range of 5 ° C to 40 ° C, preferably 10 ° C to 30 ° C, and below the cultivated soil; And the step of enlarging the roots of Pueraria Mirifica by stopping the supply of water to the water.

プエラリア・ミリフィカは最低土中温度０°Ｃ〜最高土中温度５０°Ｃの範囲内で生存するが、最適な土中温度は年間を通じて５°Ｃないし４０°Ｃ、好ましくは１０°Ｃ〜３０°Ｃの範囲内の温度（より好ましくは１５°Ｃ）であり、かかる温度に維持することが重要である。そこで、寒冷地においてもプエラリア・ミリフィカを栽培できるように、例えば栽培土壌にヒータを埋設し、栽培土壌上にヒータを敷設し、土中温度を５°Ｃないし４０°Ｃ、好ましくは１０°Ｃ〜３０°Ｃの範囲内の温度に維持するようにしている。   Pueraria Mirifica survives within a minimum soil temperature of 0 ° C to a maximum soil temperature of 50 ° C, but the optimum soil temperature is 5 ° C to 40 ° C, preferably 10 ° C to 30 ° C throughout the year. It is important to keep the temperature within the range of ° C (more preferably 15 ° C). In order to cultivate Pueraria Mirifica even in cold regions, for example, a heater is embedded in the cultivated soil, a heater is laid on the cultivated soil, and the soil temperature is 5 ° C to 40 ° C, preferably 10 ° C. The temperature is kept within a range of -30 ° C.

また、プエラリア・ミリフィカを寒冷地においてより確実に栽培できるように、温室栽培を採用し、温室内にヒータ設備と開閉窓（必要に応じて送風設備）を設け、温室内を１年を通じて５°Ｃないし４０°Ｃ、好ましくは１０°Ｃ〜３０°Ｃの範囲内の温度、好ましくは土壌温度と実質的に等しい温度に維持するのがよい。   In order to cultivate Pueraria Mirifica more reliably in cold regions, greenhouse cultivation is adopted, heater equipment and open windows (if necessary) in the greenhouse, and 5 ° throughout the year in the greenhouse. It should be maintained at a temperature in the range C to 40 ° C, preferably 10 ° C to 30 ° C, preferably substantially equal to the soil temperature.

タイ国原産地ではプエラリア・ミリフィカは３月〜１１月の雨期に緑の葉をつけて成長し、１２月〜２月の乾期に落葉し、この成長期と落葉期を支配しているのは雨量、特にプエラリア・ミリフィカの植物根が利用できる地下水量である。本発明では地下水の形式で栽培土壌の下方に水を供給するようにしている。   In Thailand, Pueraria Mirifica grows with green leaves during the rainy season from March to November, and leaves during the dry season from December to February. It is the rainfall that controls this growth and defoliation season. In particular, the amount of groundwater available to the plant roots of Pueraria Mirifica. In the present invention, water is supplied below the cultivated soil in the form of groundwater.

また、温室栽培において、水分供給を継続すると、落葉は起こらず、一年中緑の葉で覆われているが、落葉が起こらない。プエラリア・ミリフィカは落葉期に根塊の肥大が顕著であり、落葉がないと根塊の収穫が期待できない。そこで、栽培土壌の下方への水の供給と供給停止とを行い、育成期と落葉期とを人為的に作り出すようにしている。また、栽培土壌の土中温度を年間を通じて５°Ｃないし４０°Ｃ、好ましくは１０°Ｃ〜３０°Ｃの範囲内の温度に維持し、これによってもタイ国原産地における乾期の刺激と同様の刺激をプエラリア・ミリフィカに対して与えることができる。   In addition, in the greenhouse cultivation, if water supply is continued, leaf fall does not occur and it is covered with green leaves throughout the year, but leaf fall does not occur. In Pueraria Mirifica, the nodules are notable for the enlargement of the root nodules. Therefore, water is supplied to the lower side of the cultivated soil and the supply is stopped to artificially create a growing period and a defoliation period. In addition, the soil temperature of the cultivated soil is maintained at a temperature within the range of 5 ° C to 40 ° C, preferably 10 ° C to 30 ° C throughout the year, which is similar to the dry season stimulation in Thailand. Stimulation can be given to Pueraria Mirifica.

プエラリア・ミリフィカは上述のように水を求める性質が非常に強く、地中深さ３ｍ以上、横幅１０ｍ以上の広い領域にわたって根をはりめぐらし、あちこちに根塊を形成する。このような根塊の成長を管理し、又根塊を収穫する労力は非常に大きな負担となる。そこで、所定の大きさの容器の底部に水耕設備を設け、その上に栽培土壌を入れ、プエラリア・ミリフィカの根域を容器内に制限するようにするのがよい。   As described above, Pueraria Mirifica has a very strong property of demanding water, and spreads roots over a wide area having a depth of 3 m or more and a width of 10 m or more to form root nodules. The labor for managing the growth of the root nodules and harvesting the nodules is a very heavy burden. Therefore, it is preferable to provide hydroponic equipment at the bottom of a container of a predetermined size, put cultivated soil thereon, and limit the root area of Pueraria mirifica within the container.

育成期と落葉期の期間は特に限定されないが、タイ国原産地での育成条件に合わせて栽培土壌の下方からの水の供給期間を９カ月、水の供給停止期間を３カ月とするのがよい。また、プエラリア・ミリフィカの根塊が収穫できる程度に肥大化するのに数年間を必要とする。そこで、水の供給と供給停止を繰り返すようにするのがよい。   The period of the growing season and defoliation period is not particularly limited, but it is better to set the water supply period from below the cultivated soil to 9 months and the water supply stop period to 3 months according to the growing conditions in the country of origin in Thailand. . Also, it takes several years for the Pueraria Mirifica root mass to grow to the extent that it can be harvested. Therefore, it is preferable to repeat supply and stop of water supply.

日照時間は時期によって多少変化するので、タイ国原産地では電気照明を利用し、１３時間以上の日照時間を確保している。そこで、本発明でも温室内の日照時間を１３時間以上とするのがよい。   Since the sunshine hours vary somewhat depending on the season, the country of origin in Thailand uses electric lighting to ensure a sunshine duration of 13 hours or more. Therefore, in the present invention, the sunshine duration in the greenhouse is preferably 13 hours or more.

タイ国原産地の土壌は石灰岩の風化した細土からできており、又石灰岩には割れ目があって極めて水はけがよい。そこで、温室内の栽培土壌には石灰岩が風化した土壌を用いるようにするのがよい。例えば、鹿沼土からなる表層土、落葉堆肥を含む肥沃土からなる中間層土及び石灰岩の風化した土壌からなる底層土の３層構造を採用することができる。   The soil from Thailand is made of weathered fine limestone, and the limestone has cracks and is very well drained. Therefore, it is preferable to use soil with weathered limestone as cultivated soil in the greenhouse. For example, it is possible to adopt a three-layer structure of a surface soil composed of Kanuma soil, an intermediate soil composed of fertile soil including deciduous compost, and a bottom soil composed of weathered soil of limestone.

プエラリア・ミリフィカの植物根は毛根が少なく、太い根が地下水のある方向に伸長し、地下１ｍ以上の地中深くにまで根塊をつくる傾向がある。このことは温室栽培においても同様であると考えられるので、栽培土壌の深さも１ｍ以上とするのがよい。   The plant roots of Pueraria Mirifica have few hair roots, thick roots tend to extend in the direction of groundwater, and tend to form root nodules deeper than 1 m underground. Since this is considered to be the same in greenhouse cultivation, the depth of the cultivated soil is preferably 1 m or more.

さらに、タイ国原産地の水質はｐＨが６〜７であり、置換性塩基類が多く、カルシウム含有量が多いのが特徴である。そこで、栽培土壌の下方にはｐＨ６〜７で、カルシウム成分を含有する水を供給するのがよい。   Furthermore, the water quality of the country of origin of Thailand has a pH of 6-7, is characterized by a large amount of replaceable bases and a high calcium content. Therefore, it is preferable to supply water containing a calcium component at a pH of 6 to 7 below the cultivated soil.

原生のプエラリア・ミリフィカは山火事によって発芽する。そこで、プエラリア・ミリフィカの栽培を始めるにあたって、種子を酸処理又は熱処理することによって発芽を促すようにする。プエラリア・ミリフィカの種子を用いて栽培すると、収穫量にバラツキがあり、３年で１株平均２０ｋｇの収穫が可能である。しかし、いわゆる「さし木」か「とり木」の方式を用いると、３年で１株平均３０ｋｇを超える収穫が可能である。   The native Pueraria Mirifica germinates from a wildfire. Therefore, when cultivation of Pueraria Mirifica is started, germination is promoted by acid treatment or heat treatment of the seeds. When cultivated using Pueraria Mirifica seeds, the yield varies, and an average of 20 kg can be harvested in 3 years. However, if the so-called “sashiki” or “torigi” method is used, it is possible to harvest over 30 kg on average in 3 years.

つまり、プエラリア・ミリフィカの茎、芽又は葉の形成層、根の先端部、あるいは根塊の成長点を採取して活着床に移した後、１〜２週間すると活着して成長を開始するので、栽培土壌に移し、前述の栽培条件によって管理・栽培すると、収穫量をアップさせることができる。   In other words, after the growth point of Pueraria Mirifica stalk, bud or leaf formation layer, root tip, or root nodule is collected and transferred to the bed, it will settle and start growing after 1-2 weeks. When transferred to cultivated soil and managed and cultivated under the above-mentioned cultivation conditions, the yield can be increased.

以下、本発明を実施例に基づいて詳細に説明する。   Hereinafter, the present invention will be described in detail based on examples.

プエラリア・ミリフィカの根塊の成長点を種とし、これに殺菌処理を施した。殺菌処理は中性殺菌剤に漬けて行った。殺菌処理した根塊を成長ホルモン液に漬け、活着床に移した。根塊の成長点を活着床に移して１〜２週間程度すると、根塊の成長点が活着し、成長を開始した。そのことを確認した後、活着した根塊の成長点を温室の栽培土壌に移した。   The roots of Pueraria mirifica were used as seeds and sterilized. The sterilization treatment was performed by immersing in a neutral disinfectant. The sterilized root mass was soaked in a growth hormone solution and transferred to an active bed. When the growth point of the root nodules was transferred to the bed for about 1 to 2 weeks, the growth points of the root nodules were settled and started growing. After confirming that, the growth point of the rooted root mass was transferred to the cultivated soil in the greenhouse.

温室はヒータ設備及び開閉窓を設け、１年を通して、つまり夏期及び冬期において室内環境温度を最低１０°Ｃ、最高３０°Ｃの範囲内の温度、好ましくは１５°Ｃの温度に維持できるようにした。   The greenhouse is equipped with heaters and windows, so that the indoor environment temperature can be maintained at a minimum temperature of 10 ° C and a maximum temperature of 30 ° C, preferably 15 ° C throughout the year, that is, in summer and winter. did.

また、温室内には栽培土壌を入れた容器を並べた。容器は木板を用いて横幅１ｍ×高さ１ｍで縦数ｍの大きさに組み立て、縦をほぼ１ｍ毎に仕切った。なお、横幅１ｍ×高さ１ｍ×縦１ｍの大きさに組み立ててもいい。この容器内の栽培土壌のうち、数ｃｍの表層土には鹿沼土を、７０ｃｍ〜８０ｃｍの中間層土には落葉堆肥を含む肥沃土を用い、底層土には原産地と同様に、石灰岩が風化した土壌を用い、三層構造とした。いずれの土壌も使用前に１００°Ｃ〜１２０°Ｃの環境温度中でネット上に土壌を載せ、攪拌しながら０．１５時間〜０．４５時間で熱殺菌を行い、既存の病原性微生物を除去する。   In the greenhouse, containers with cultivated soil were arranged. The container was assembled in a size of 1 m in width and 1 m in height by using a wooden board, and the length was partitioned approximately every 1 m. In addition, you may assemble to the magnitude | size of width 1m x height 1m x length 1m. Of the cultivated soil in this container, Kanuma soil is used for the surface soil of several centimeters, fertile soil containing deciduous compost is used for the intermediate soil of 70 cm to 80 cm, and limestone is weathered in the bottom soil, as in the origin. The soil was made into a three-layer structure. Before using any soil, place the soil on a net at an ambient temperature of 100 ° C to 120 ° C, heat sterilize it with stirring for 0.15 hours to 0.45 hours, and remove existing pathogenic microorganisms. Remove.

肥料は殺菌処理した肥沃土に落葉堆肥を混合して元肥として施したが、窒素、リン酸、カリウムなどを含んだ液肥を必要に応じて使用した。   Fertilizer was mixed with sterilized fertilizer and mixed with deciduous compost as the original fertilizer, but liquid fertilizer containing nitrogen, phosphoric acid, potassium, etc. was used as needed.

栽培土壌にもヒータ設備を埋設し、あるいは土壌の上に載せ、１年を通して土中温度を最低１０°Ｃ、最高３０°Ｃの範囲内の温度、好ましくは１５°Ｃの温度に維持できるようにした。   Heater equipment is also embedded in the cultivated soil or placed on the soil so that the soil temperature can be maintained at a temperature within a range of at least 10 ° C and a maximum of 30 ° C throughout the year, preferably 15 ° C. I made it.

灌漑用水は容器の底部に水耕設備を設け、地下水形式で根に供給するようにした。水耕設備には例えば送水管の上半部に多数の孔をあけ、この送水管に送水する方式、あるいは栽培土壌の下側に不織布や小石を敷設し、不織布や小石に水を供給する方式、などを採用することができる。   The irrigation water was provided with hydroponic equipment at the bottom of the container and supplied to the roots in the form of groundwater. In hydroponic equipment, for example, a number of holes are made in the upper half of the water pipe, and water is supplied to the water pipe, or a non-woven fabric and pebbles are laid under the cultivation soil, and water is supplied to the non-woven fabric and pebbles. , Etc. can be employed.

供給する水にはｐＨ６〜７で、置換性塩基類、例えばＣａＣｌ2・２Ｈ2Ｏなどを含有する水を用いた。 The water to be supplied was pH 6-7 and contained water containing a replaceable base such as CaCl 2 .2H 2 O.

活着した根塊の温室内の栽培土壌への移植は３月に行い、１１月まで上述の環境温度の保持と水の供給とを行った。その間は緑の葉が繁り、プエラリア・ミリフィカが成長し、その根は地下水源に向けて伸長した。１２月になると、上述の環境温度の保持を行ったまま水の供給を停止し、その状態を２月まで継続した。その間に落葉が起こり、根が肥大化した。   Transplanting the rooted root mass to the cultivated soil in the greenhouse was carried out in March, and the above-mentioned environmental temperature was maintained and water was supplied until November. Meanwhile, green leaves grew, Pueraria Mirifica grew, and its roots extended towards the groundwater source. In December, the supply of water was stopped while maintaining the above environmental temperature, and the state was continued until February. During that time, defoliation occurred and the roots became enlarged.

このプエラリア・ミリフィカの成長と根の肥大化とを３年間繰り返し、根塊を収穫した。収穫量は１株あたり３０ｋｇを超える量であった。   The growth of the Pueraria Mirifica and the enlargement of the roots were repeated for 3 years, and the root mass was harvested. The yield was over 30 kg per strain.
