【発明の詳細な説明】DETAILED DESCRIPTION OF THE INVENTION
【０００１】[0001]
【０００２】本発明は甘藷苗の水耕栽培方法に関し、詳
細には、本畑に定植して甘藷イモを生産するために利用
される甘藷苗の水耕栽培方法に関する。The present invention relates to a method for hydroponically cultivating sweet potato seedlings, and more particularly to a method for hydroponically cultivating sweet potato seedlings which are used for producing sweet potatoes by planting them in a main field.
【０００３】[0003]
【０００４】従来、甘藷の定植用の苗の栽培は、主に土
床栽培によって行われている。Conventionally, the cultivation of seedlings for planting sweet potatoes is mainly performed by soil cultivation.
【０００５】例えば、種イモを用いた栽培では、種イモ
を土壌消毒した土床に伏せ込み、種イモから萌芽した蔓
を切除することで、甘藷苗を栽培している。[0005] For example, in cultivation using seed potatoes, sweet potato seedlings are cultivated by laying down seed potatoes on a soil-disinfected soil floor and cutting off vines sprouting from the seed potatoes.
【０００６】また、ウィルス病対策のために無菌的に組
織培養したウィルスフリー苗を用いた栽培では、ウィル
スフリー苗を土壌消毒した土床に定植し、伸長した蔓を
順次切断することで、甘藷苗を栽培している。[0006] In cultivation using virus-free seedlings that have been aseptically cultured for virus disease control, the virus-free seedlings are planted on a soil-disinfected soil bed, and the elongated vines are sequentially cut to obtain sweet potatoes. Growing seedlings.
【０００７】[0007]
【０００８】しかしながら、上記したように、甘藷苗の
栽培を土床栽培によって行う場合には、次のような解決
すべき課題を有していた。However, as described above, when cultivating sweet potato seedlings by soil cultivation, there are the following problems to be solved.
【０００９】種イモを用いた栽培では、１０ａ分の苗を
生産するのに種イモを２００ｋｇ程必要とし、土床や種
イモの消毒が必要である上に、採苗の都度追肥を必要と
するので、肥培管理が容易でない。Cultivation using seed potatoes requires about 200 kg of seed potatoes to produce 10a seedlings, disinfecting the soil bed and seed potatoes, and also requiring additional fertilization each time seedlings are harvested. Therefore, fertilizer management is not easy.
【００１０】さらに、外観上からウィルス病に汚染され
ている種イモを排除するのは難しく、サツマイモ斑紋モ
ザイクウィルス等に感染していた種イモから苗を採取す
ると、塊根の表面に帯状の褐色のかさかさした帯状粗皮
症が発生し、イモの品質が低下することが多い。Furthermore, it is difficult to remove the seed tuber that is contaminated with the virus disease from the appearance. Bulk shingles often occur, reducing the quality of the potato.
【００１１】また、ウィルスフリー苗を用いた栽培で
は、サツマイモ斑紋モザイクウィルス等のウィルス病に
よるイモの品質低下を防ぐことはできるが、土床でのウ
ィルスフリー苗の活着率が７０〜８０％程度と低い上
に、種イモを用いた場合と同様に、土床の消毒が必要で
あり、肥培管理が容易でない。Cultivation using virus-free seedlings can prevent the deterioration of potato quality due to virus diseases such as sweet potato mottled mosaic virus, but the survival rate of virus-free seedlings on the soil floor is about 70-80%. In addition, as in the case of using seed potatoes, it is necessary to disinfect the soil bed, and it is not easy to manage fertilizer.
【００１２】さらに、甘藷の場合には根が培地等の他の
物質に接触することによりイモを形成しやすくなるとい
われており、地中に伸びた甘藷苗の根にイモができるこ
とで蔓の伸びが低下し、甘藷苗の生産力が低くなること
がある。[0012] Further, it is said that in the case of sweet potatoes, the roots are liable to form potatoes by coming into contact with other substances such as a culture medium. And the productivity of sweet potato seedlings may decrease.
【００１３】なお、ウィルスフリー苗を、砂やロックウ

といわれる方法で水耕栽培した場合や、毛管水耕といわ
れる吸水性の不織布上に苗を定植し、根を湿気中で生育
させる方法で水耕栽培した場合は、土床栽培と同様に、
根が培地等の他の物質に接触することにより、甘藷苗の
根にイモができることで蔓の伸びが低下し、甘藷苗の生
産力が低くなることがある。When virus-free seedlings are cultivated hydroponically using sand, rock wool or the like as a medium, or NFT is supplied intermittently with a thickness of several millimeters of a culture solution in a ditch in which seedlings are planted.
In the case of hydroponic cultivation by the method called, or when the seedlings are planted on a water-absorbent nonwoven fabric called capillary hydroponic culture, and when the roots are cultivated in a method of growing the roots in moisture, like soil culture,
When the roots come into contact with other substances such as a culture medium, potatoes are formed on the roots of the sweet potato seedlings, thereby reducing the growth of the vines and reducing the productivity of the sweet potato seedlings.
【００１４】従って、甘藷苗の活着率が高い上に、土床
の消毒等の手間がかからず、肥培管理が容易であり、培
養液中の甘藷苗の根にイモができることなく、蔓が順調
に伸長し、甘藷苗の生産力の低下を防ぐことができる手
段が望まれていた。Therefore, the survival rate of the sweet potato seedlings is high, the labor of disinfecting the soil floor is not required, and the fertilizer management is easy. There has been a demand for a means that can grow smoothly and prevent a decrease in the productivity of sweet potato seedlings.
【００１５】[0015]
【００１６】本発明の課題を解決するための手段は、下

ないように浸し、遮光して順化を行った後、段階的に培
養液の濃度を高めて栽培することを特徴とする、前記第
１記載の甘藷苗の水耕栽培方法である。Second, during the hydroponic culture, the roots of the sweet potato seedlings were immersed so as not to come into contact with other substances while the concentration of the culture solution was adjusted to a low concentration, and the plants were acclimated to light. 2. The method for hydroponically cultivating sweet potato seedlings according to the first aspect, wherein the cultivation is performed by increasing the concentration of the culture solution stepwise thereafter.
【００１９】第３に、培養液のＥＣ値（電気伝導度）

った。As shown in Table 4, when planted in a hydroponic cultivation apparatus, the survival rate of the seedlings was higher than that planted on the soil floor, and although the number of seedlings collected per unit area was not much different, the planting rate was lower. The number of seedlings collected from one seedling was more than twice the number of soil beds, and it was revealed that the efficiency of collecting seedlings was high.
【００６３】なお、水耕栽培装置に定植した場合は、土
床栽培のように、栽培中に地下部にイモが付かないの
で、蔓の伸長が栽培期間の後半まで続いた。In the case of planting in a hydroponic cultivation apparatus, as in the case of soil cultivation, potatoes did not adhere to the underground during cultivation, so that the growth of the vine continued until the latter half of the cultivation period.
