本発明は植物の低温栽培方法とその装置に関し、例えば
イチビ、シクラメン、シンビジューム等の植物の花芽を
９期に分化させたり、冬作物（低温作物）を高温期に栽
培したりできるようにしたものである。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a low-temperature cultivation method for plants and an apparatus thereof, such as for differentiating flower buds of plants such as cyclamen, cyclamen, and cymbidium into 9 stages, and for cultivating winter crops (low-temperature cultivation). crops) can be cultivated during high-temperature periods.
（従来技術）
イチビ、シクラメン、シンビジューム等の植物の花芽を
早期に分化させる方法として従来は山場法、株冷法、夜
冷法などがある。(Prior Art) Conventional methods for early differentiation of flower buds of plants such as Japanese crocodile, cyclamen, and cymbidium include the mountain method, the stock cooling method, and the night cooling method.
山場法は１０００メートル以上の高齢地に株を植えて平
地に植える場合よりも早く花芽分化させるものである。The mountain method involves planting plants in aged land at a height of 1,000 meters or more and causing them to differentiate into flower buds more quickly than when planted on flat land.
株冷法は株に付着している土を落して株のみを冷蔵庫に
入れて冷やして花芽分化させるものである。In the stock cooling method, soil attached to the plants is removed and only the plants are placed in the refrigerator to cool and differentiate into flower buds.
夜冷法は株を育苗箱に密植し、育苗箱内の培地を少くし
、株数を多くしてその株が冷え易いようにし、それをを
苗箱ごと冷却室内に収納して冷やして花芽分化させるも
のである。The night cooling method involves planting plants densely in a seedling box, reducing the amount of medium in the box, increasing the number of plants so that the plants can cool easily, and then storing the seedling box together in a cooling room to cool it and allow flower bud differentiation. It is something that makes you
（従来技術の問題点） 従来の花芽分化方法では次のような問題があった。(Problems with conventional technology) Conventional flower bud differentiation methods have the following problems.
（１）山場法では山に植えるときに市を山に連び１−げ
、花芽分化してから平地に下さなければならず、また植
えたあとも消毒や水かけ等の管理のため平地と山を往来
しなければならないので時間と労力がかかり作業が大変
であった。(1) In the mountain field method, when planting on a mountain, it is necessary to connect the seeds to the mountain, differentiate into flower buds, and then lower it to the level ground. Also, even after planting, it must be kept on the level ground for management such as disinfection and watering. The work was difficult and time consuming as it required traveling back and forth through the mountains.
（２）株冷法では株に上がほとんど付着していないので
根が腐ったり傷んだりし易く、−花房あたりの収＃ＩＪ
量が山場法に比して少ない。(2) In the plant cooling method, the top of the plant is hardly attached to the plant, so the roots are easily rotted or damaged, and - Yield per flower cluster #IJ
The amount is smaller than that of Yamaba method.
（３）夜冷法では昼は育苗箱を屋外に出し、夜は屋内に
収納しなければならないのでその出し入れ作業が面倒で
あった。また育苗箱を収納するための建物や、建物内で
育苗箱を−Ｆ下に植土げるための棚や、育苗箱を出し入
れするためのレールなどの設備が必要であるため設備費
が高くなり、更には屋内全体を冷やすのでランニングコ
ストが高くなるといった問題があった。(3) In the night cooling method, the seedling box had to be taken outside during the day and stored indoors at night, making it troublesome to take it in and out. In addition, equipment costs are high because facilities such as a building to store the seedling boxes, a shelf to plant the seedling boxes under -F in the building, and a rail to take the seedling boxes in and out are required. Furthermore, there was a problem in that running costs were high because the entire indoor space was cooled.
（４）上記の従来方法はいずれも花芽分化を促進させる
ことを目的としたものであるため、それらの方法により
低温期の植物を高温期に栽培することは困難であった。(4) Since all of the above-mentioned conventional methods are aimed at promoting flower bud differentiation, it has been difficult to cultivate plants in the low temperature period in the high temperature period using these methods.

Cool air is sent from the tunnel to inflate the film 3 as shown in FIG. 2, and the tunnel 2 is formed by maintaining the inflated state even without the support. In this state, if cold air is continued to be supplied to the refrigerant passage 4 to maintain the inside of the tunnel at a predetermined low temperature (for example, 10-15° C.), flower bud differentiation of the plant will be promoted. In the case of flower bud differentiation, cold air is supplied only at night, and during the day the film 3 is removed and the plants 1 are exposed to sunlight. In addition, in this way, plants that are normally cultivated during the low temperature period can also be cultivated during the high temperature period.

In these figures, G is a ridge, l is a plant, 2 is a tunnel, 3 is a film, 4 is a refrigerant passage formed on the inner ceiling of the film, 5 is a refrigerant discharge hole, and 6 is a pot with a plant planted in the film 3. It is preferable to use an aluminum cloth sheet or a combination of an aluminum sheet and a foam sheet.Using these films 3 blocks sunlight, exhibits short-day and heat-insulating effects, and promotes flower bud growth. A more suitable environment for differentiation can be created.

ル２の長手方向に沿って形成する。Although the refrigerant passage 4 in Figs. The refrigerant passage 4 of 454 is molded integrally with the film 3, but the refrigerant passage 4 may be molded separately from the film 3 and attached to the film 3, or the refrigerant passage 4 may be formed with a refrigerant outlet 5 as shown in FIG. A metal pipe 8 may be installed next to the ridge G inside the tunnel 2. In either case, the refrigerant passage 4 is formed along the longitudinal direction of the tunnel 2.
冷気排出孔５は冷媒通路４の長手方向に適宜間隔で形成
されており、冷媒通路４に供給された冷気がトンネル２
内全般に均一に排出されるようにしである。The cold air discharge holes 5 are formed at appropriate intervals in the longitudinal direction of the refrigerant passage 4, and the cold air supplied to the refrigerant passage 4 is discharged from the tunnel 2.
This is to ensure uniform discharge throughout the interior.

ないようにするが。In FIGS. 1 and 2, one end 3a of the film 3 in the width direction is fixed to the ground G by placing a ±6 as shown in FIG. 2, and the opposite end 3b can be opened and closed. Opening/closing end 3
When supplying cold air, b should be fixed to the ground G to prevent cold air from leaking.

３ｂから漏れる量よりも多くしてフィルム３を膨らます
。If the tunnel 2 is completely sealed, the tunnel 2 will be filled with cold air, making it impossible to supply cold air later. Therefore, it is better not to seal the opening/closing end 3b, but rather to leave a slight gap so that some cold air in the tunnel can leak out from the gap.In this way, new cold air will be supplied to compensate for the leakage. Therefore, the inside of tunnel 2 is kept at a constant low temperature (for example, about 10 to 15 degrees Celsius).
can be kept. When starting to introduce cold air into the film 3, the amount of cold air supplied into the tunnel is made larger than the amount leaking from the opening/closing end 3b to inflate the film 3.

る程度気密性も確保される。As a method of fixing the opening/closing end 3b, for example, as shown in FIGS. 2 and 3, a liquid passage 7 is formed in the irA end 3b, and a liquid such as water or sand is supplied to the passage 7. This allows the opening/closing end 3b to come into contact with the ground due to the weight of the wood and sand, and also to bend following the unevenness of the ground, thereby ensuring airtightness to some extent.
第１図〜第３図のものはフィルム３を冷気だけで膨らま
すものであるが、第４図のものは通常のトンネル栽培の
トンネルと同様に、フィルム３を支柱ｌＯで支持したも
のである。In the ones shown in FIGS. 1 to 3, the film 3 is inflated only by cold air, but in the one shown in FIG. 4, the film 3 is supported by supports 1O, like a tunnel for ordinary tunnel cultivation.

ていないものを使用する。In both of the following two embodiments, air cooled outside the tunnel 2 is supplied to the refrigerant passage 4, but in the case of Fig. 6, the air supplied to the refrigerant passage 4 is uncooled normal air. The air is cooled by a refrigerant such as Freon gas supplied into the metal pipe 8, and the cooled air is discharged into the tunnel 2. In this case, the metal pipe 8 used does not have an exhaust port formed therein.
