Description

  The present invention cools the mango tree grown in the house together with the cultivation container to cause flower bud differentiation and blooms, then warms the cultivation container and enlarges the mango fruit, making mango freely regardless of the season It relates to a cultivation container for mango to be born.

  In recent years, mango is popular among consumers as a fruit having a very strong sweetness and fragrance, and has attracted attention as a fruit that can be sold at a high price from the producer's side. Therefore, farmers who produce mango want to be able to obtain a higher quality, more efficiently, and to harvest at a time when domestic mango is not harvested.

Mango trees can reach up to 10 m in straight roots and are usually large trees that grow to a height of 20 m or more unless pruning or the like is performed. When mango trees are hot and have moderate soil moisture, they grow into large trees by repeating the emergence of new treetops 2-3 times a year. Mango trees die when the minimum winter temperature falls below 5 ° C. In Japan, it is normal to cultivate greenhouses such as vinyl houses. Since the height of the house is generally 3.5 m to 4.0 m, it is necessary to prun the mango tree several times in order to grow without breaking the house. Further, when the temperature is higher than 35 ° C., the mango tree is damaged by high temperature, so it is necessary to adjust the temperature.

Mango is a plant belonging to the family Ursiaceae, and the mango flower is a tufted inflorescence that arrives at the tip of a branch. In this inflorescence there are amphoteric flowers and male flowers, which are pollinated and bear fruit. It is said that when the ratio of amphoteric flowers is 10% or less, the number of fruits is reduced. In mango, 8 to 13% of flowering flowers are fruited, but most fruits fall within a week, and it is said that it takes less than 1% until harvest. In addition, mango trees are originally plants that are resistant to drying. However, soil drying after the flowering period causes falling fruit and poor growth, so it is necessary to irrigate frequently.

The most common cultivation method is to harvest mango from June to July by full-ripe production. Usually, in this case, after harvesting the mango, the branches are pruned to prevent the mango tree from becoming a large tree, the temperature is adjusted to 20 ° C. to 30 ° C., and the new tree is generated twice. Recover and accumulate nutrients. However, when the third shoots are generated, nutrient accumulation is not performed, no flowers are attached to the tip, and fruit production becomes impossible. Then, around November, flower bud differentiation begins when the temperature falls below 15 ° C. When it starts to come out in January, the temperature of the house is 20 ° C. to 25 ° C., and the temperature of the house is 25 ° C. to 30 ° C. from the flowering period to the fruit enlargement period around February. The higher the temperature, the better the fruit enlargement and the better the skin color. In addition, the cleavage of mango cocoons requires 20 ° C. or higher, and the pollen tube grows well at 25 ° C. to 30 ° C. On the other hand, pollen is inhibited from germination at a low temperature of 15 ° C. or lower and a high temperature of 35 ° C. or higher. Therefore, it is normal to use house cultivation in regions that do not reach high temperatures up to 30 ° C.

Mango is flowered in the winter, when the temperature falls below 15 ° C., and flower bud differentiation begins to bloom. As a result, mango is usually harvested from April to July. Therefore, in Japan, no mango was harvested in winter, especially during Christmas. Mangos circulated in Japan during the Christmas season are imported from the southern hemisphere. However, imported mango is harvested early so that it can be transported and stored for a long time. In addition, because it is quarantined and stored at a low temperature, the taste and flavor are further impaired. Therefore, if mango can be harvested in the winter season, mango, which is originally a high-class fruit, can be sold with added value. As a prior art related to this, an invention that reduces fossil fuel used for heating and enables continuous harvest and shipment from October to early January is disclosed as a prior art [Reference 1].

JP 2009-207489 A ([0001 to 0021], [FIG. 1])

It is described that the cultivation method by the heating facility of the mango which is the prior art can reduce the amount of fossil fuel used in the heating facility by providing a dormancy period and can continuously harvest and ship from October to early January. However, a method for causing flower bud differentiation in a hot season when the temperature is 15 ° C. or higher is not disclosed and has not yet been specifically solved.

Here, the Peltier module is a unit in which N-type, P-type, and N-type semiconductors are connected in series. When a direct current is passed from an N-type semiconductor to a P-type semiconductor, heat is absorbed (cooled) at the contact, and conversely, when a direct current is passed from the P-type semiconductor to the N-type semiconductor, heat is generated (heated). Therefore, the cultivation container according to the present invention can cool or heat the cultivation container and the soil in the container depending on the direction of the direct current flowing through the Peltier module. In addition, although you may make all the cultivation containers using the material which has good heat conductivity, even if you can use the material which has good heat conductivity for a part of the cultivation container if heat can be transmitted to the soil Good.

  According to the main cultivation container, the mango tree that has been sprouting and enriched twice and stored nutrients feels the temperature at the leaves, roots and trunk, and starts to differentiate when the temperature changes from 5 ° C to 15 ° C. It is. Therefore, by cooling the main cultivation container with the cooling effect of the Peltier module, the temperature of the cultivation container can be adjusted to 5 ° C. to 15 ° C. Therefore, in house cultivation in a vinyl house, the temperature inside the house If the temperature is adjusted to 5 to 15 ° C, the mango tree stocked with nutrients and ready for flower bud differentiation can feel temperature changes not only from the leaves, roots and trunks but also from the roots. Therefore, flower bud differentiation can be started regardless of the season, and further fruiting can be achieved. In addition, during the shoot emergence period and fruit enlargement period, the direct current of the Peltier module is passed in the reverse direction to heat the main cultivation container to bring the soil temperature to 20 ° C. to 30 ° C. Since it can be warmed, the tree of the mango can be restored and the fruit of the mango can be enlarged. As a result, mango can be produced and sold at a higher price in the season when mango is not popular in Japan.

FIG. 4 is a mango cultivation method according to an embodiment for carrying out the present invention, in which a cultivation container in which a mango tree is planted is divided into groups, and heat radiation of the cooling group is utilized by the heating group for heating. It is a typical perspective view which shows the state which is performing.

FIG. 1 is a mango cultivation container according to an embodiment for carrying out the present invention, in which (a) is a perspective view of a mango cultivation container in which a mango tree is planted, and (b) is in (a). The AA arrow sectional drawing of the cultivation container of the mango which planted the mango tree is shown. The cultivation container 1 for mango according to the present invention is composed of a cooling / heating device 3 and a container 2 for planting mango. The cooling / warming device 3 includes a Peltier module 3-1, a temperature sensor 3-2, a finned heat sink 3-4, a finless heat sink 3-5, and a cooling fan 3-6. To do. The Peltier module 3-1 is a unit formed by connecting N-type, P-type, and N-type semiconductors in series. When a direct current is passed from the N-type semiconductor to the P-type semiconductor, the Peltier module 3-1 absorbs heat (cools) at the contact point. Conversely, when a direct current is passed from the P-type semiconductor to the N-type semiconductor, heat is generated (heated). Heat generated or absorbed by the contact is transmitted to an object to be heated or cooled by heat transfer or convection to be heated or cooled.

  When cooling the mango cultivation tree, the heat of the container 2 in which the mango is planted is absorbed by the Peltier module 3-1 via the finless heat sink 3-5, and the absorbed heat is absorbed by the Peltier module 3-1. The heat is transmitted to the finned heat sink 3-4 and is radiated to the outside. At this time, the air cooling function by the fin is enhanced by the cooling fan 3-6. Moreover, when heating the cultivation tree for mango, the heat of the finned heat sink 3-4 is absorbed by the Peltier module 3-1, and the absorbed heat is not present in contact with the Peltier module 3-1. It is transmitted to the container 2 for planting mango through the heat sink 3-5, and the cultivation container 2 is heated. By using these means to heat or cool the container 2 in which the mango is planted, the heat can be transmitted to the soil 22 in the container 2 to cool or warm the soil 22. Thereby, the temperature of the root part of the mango tree 21 planted in the container 2 can be changed. It is important that the cooling / heating device 3 having the Peltier module 3-1 as a main component is in close contact with the side surface of the container 2 to efficiently transfer heat generated or absorbed by the Peltier module 3-1. It is. For this purpose, the container 2 is manufactured using a material having good heat conductivity. As a material having good heat conductivity, a metal such as copper, aluminum, brass, or steel is preferably used, and graphite is used as a nonmetal. May be. Moreover, if heat can be transmitted to the soil 22, a belt-like material having good heat conductivity can be used for a part of the container 2. Moreover, in order to transmit cooling and heating heat efficiently to the soil 22 in the cultivation container 2, it is also necessary to provide the heat insulating material 4 on the outer side of the container 2 to suppress heat radiation to the outside.

  The Peltier module 3-1 in the cooling / warming device 3 is loaded on the Peltier module 3-1 by a signal from a temperature sensor 3-2 that measures at least one of the temperature of the container 2 and the temperature of the soil 22 in the container 2. Connected to a control device 3-3 for controlling the current and polarity. For example, if the set temperature is set to 8 ° C to 13 ° C, the temperature of the soil 22 in the container 2 can be maintained at 8 ° C to 13 ° C.

FIG. 2 is a flowchart in the mango cultivation method for carrying out the present invention, and shows the relationship between the mango cultivation cycle for one year and the temperature. In the cultivation method using the mango cultivation apparatus according to the present invention, the temperature of the cultivation container 1 is set to 5 ° C. to 15 ° C., and the nutrients are sufficiently accumulated so that the flower buds can be differentiated. Is placed in a house 32 having a temperature of 5 to 15 ° C. or in the film 11 shown in FIG. 3 to perform flower bud differentiation, and then the temperature in the cultivation container 1 and 20 to 30 ° C. and the temperature in the house 32 or the film 11. Is set to 20-30 ° C. to produce mango fruit, and temperature control is very important in the cultivation method using the mango cultivation apparatus according to the present invention. Here, unless the temperature is set to 15 ° C. or lower as described above, the mango tree cannot differentiate into flower buds. Therefore, normally, only imported mango is not available during the Christmas season. If mango can be harvested during the Christmas season, it will be possible to add value to the harvested mango. Therefore, as an example of the mango cultivation method according to the present invention, a method for harvesting mango during the Christmas season in house cultivation will be described with reference to FIG.

The temperature in the house 32 or the film 11 and the temperature of the cultivation container 1 cultivating mango are set to 20 to 30 ° C., and the branches are pruned by 1 to 2 stretches around February and fertilized. From February to April, the temperature in the house 32 or the film 11 and the temperature of the cultivation container 1 are kept at 20 to 30 ° C., and the amount of watering is increased to generate, extend and enrich the new tree. Therefore, the accumulation of nutrients should be sufficient so that flower buds can be differentiated. Then, from May to July, the temperature in the house 32 or the film 11 and the temperature of the cultivation container 1 are set to 5 to 15 ° C. to forcibly cause flower bud differentiation. After flower bud differentiation has occurred, the temperature in the house 32 or the film 11 and the temperature of the cultivation container 1 are returned to 20 to 30 ° C. In mango, pollen germination is inhibited at a high temperature of 35 ° C. or higher. Therefore, the temperature in the house 32 or the film 11 in the flowering season and the flowering season in about August and the temperature of the cultivation container 1 are 25-30. Although it is necessary to adjust the temperature to ° C., the temperature is usually high at this time, so there is no need for heating and the electricity bill can be saved. Further, during the fruit enlargement period from October to December, the temperature in the house 32 or the film 11 and the temperature of the cultivation container 1 are maintained at 25 to 30 ° C., and the amount of watering is increased to increase fertilization. After that, mango is harvested during the Christmas season from December to January and the year-end and New Year period, and it becomes possible to sell it at a high price when domestic mango is not available. In addition, since the cultivation container 1 can be heated, only soil temperature is warmed to 20-30 degreeC by heating soil and setting the temperature of the soil 22 in the cultivation container 1 to 20-30 degreeC. The mango tree 2 can grow faster than the case, mango fruit enlargement can be promoted, and the skin color can be improved.

FIG. 3 is a cultivation container for mango according to an embodiment for carrying out the present invention, and (a) is installed without burying a cultivation container in which a mango tree covered with a film is planted. It is a typical perspective view which shows a state, Comprising: (b) is a typical perspective view which shows the state which has embed | buried the cultivation container which planted the mango tree covered with the film in the soil of a house, The cultivation container 1 in a state in which the trees 21 are planted is covered with the film 11 supported by the support columns 12 for cultivation. In this apparatus, an air conditioner 13 is installed, and the temperature in the film can be set to 5 ° C. to 30 ° C. If this apparatus is used and the temperature in the film is set to 5 ° C. to 15 along with the temperature of the cultivation container 1, the mango tree 21 in a state where flower bud differentiation is possible can be forcibly differentiated. Moreover, if the temperature of the cultivation container 1 and the air temperature in a film are set to 20-30 degreeC, the fruit enlargement of a mango and tree recovery can be performed efficiently. In addition, the scale of the film to be covered may be such that the mango tree is completely hidden. Since this apparatus is very compact and does not require the construction of a large-scale cultivation house, it can be easily used at home and can be harvested at the time of its own preference. For cooling and heating the atmosphere in the film, a cooling / heating device having a small Peltier module as the main component may be used instead of using the air conditioner 13.

FIG. 4 is a mango cultivation method according to an embodiment for carrying out the present invention, in which cultivation containers in which mango trees are planted are divided into groups, and heating is performed by using the heat radiation of the cooling group for the heating group. It is a typical perspective view which shows the state performed. Although the mango tree 21 can be differentiated at the same time, dividing the mango tree 21 into several blocks and causing the flower bud differentiation for each block produces a warm exhaust cooled for the flower bud differentiation. It is possible to use for heating the mango tree 21 that is performing fruit enlargement with the block of, and it is possible to keep down the cost for heating. Further, by causing the flower buds to differentiate for each block, it is possible to shift the flowering time and shift the subsequent harvesting time, and it is possible to harvest and ship from the Christmas season to the beginning of the year.

Moreover, the cultivation container 1 which concerns on this invention is used also in order to restrict | limit the root area of the root of the mango tree 21. FIG. If a mango tree usually becomes a large tree and is left unattended, it will break through the roof of the house 32 in house cultivation. Although the root of the mango tree 21 may extend 10 m or more, since the cultivation container 1 exists, the root of the mango tree 21 cannot go out of the cultivation container 1 and does not extend any longer. Therefore, the growth of the mango tree 21 is suppressed, and it is possible to prevent the house 32 from being destroyed without becoming a large tree.

Moreover, even if the mango tree 2 has withered, the root of the mango tree 21 is prevented from being deeply extended by the cultivation container 1, so that it can be easily dug out. Replacement is also easy. In addition, when cultivating a mango tree by burying the cultivation container 1 in the soil 31 of the agricultural field, the soil 31 of the agricultural field is used to cultivate the mango tree 21 as compared with the case of directly planting in the soil 31 of the agricultural field. Even if it is not suitable, it is sufficient to make only the soil 22 in the cultivation container 1 a good quality soil, and the amount of soil for soil improvement can be minimized. Further, in the cultivation in the house 32, when the cultivation container 1 is embedded in the soil 31 of the agricultural field and the mango tree 21 is cultivated, the ground height can be lowered by the height of the cultivation container 1 compared to the case where the cultivation container 1 is not embedded. Therefore, since the mango tree 21 can be raised with respect to the roof of the same house, the trunk of the mango tree 21 can be made thicker and a strong mango tree can be grown.

Moreover, the water-permeable hole 5 which has water permeability is provided in at least any one of the side part of the cultivation container 1, or the bottom part. Thereby, the water | moisture surplus by irrigation can be rapidly discharged | emitted to the exterior of the cultivation container 1, and the root rot of the mango tree 21 can be prevented. In addition, if the water-permeable root-proof sheet | seat which has water permeability is stuck inside the water-permeable hole 5 of the cultivation container 1, although excess water can be discharged | emitted from the water-permeable hole 5, the root of the mango tree 21 does not come out. It becomes like this. Furthermore, not only the moisture and nutrients present in the soil 22 in the cultivation container 1 but also the moisture and nutrients in the soil 31 of the agricultural field permeate the water-permeable root-proof sheet and enter the soil 11 in the cultivation container 1. Therefore, the mango tree 21 grows faster than pot cultivation that is not embedded in the soil 31 of the agricultural field. Moreover, when watering, it is only necessary to water only the soil 22 in the cultivation container 1, and it is not necessary to water outside the cultivation container 1 where the root of the mango tree 21 is not stretched, and it is very efficient. Furthermore, there is little waste of water with respect to the amount of watering, and it becomes easier to manage the amount of water when watering.

  Moreover, since the cultivation container 1 which concerns on this invention can be heated, before planting the mango tree 21, the soil in a cultivation container can be heated and a pest can be exterminated.

  It can be used not only for mango but also for cultivated plants in which flower bud differentiation is induced by temperature changes to low and high temperatures.
