Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method and apparatus for cultivating wasabi that can freely grow and cultivate wasabi without being restricted by region, climate, or location.

(Prior Art) Cultivation of Resabi has traditionally required a large amount of water flow, and since it is a semi-shade plant, sunlight conditions are difficult, and it is sensitive to temperature changes, so there is a large difference between successful and unsuccessful crops. Also, the growing period is 1
Since it lasts for a long period of up to two years, it can only be cultivated in specific regions and places that suit the climatic conditions. Furthermore, diseases, especially those caused by viruses and bacteria, can have fatal consequences in the cultivation of wasabi. In particular, if a completely controlled cultivation method is used for the purpose of vegetative propagation, and the rice is soaked with viruses or bacteria in the water, the bacteria will be instantly transmitted to the environment, resulting in an extremely low productivity and an increase in the number of bacteria. Not only does this cause the wasabi's sagging disease and skin disease, reducing its value as a product, but it also ends the life of the wasabi.

By the way, as an artificial cultivation method for wasabi, Japanese Patent Publication No. 53
The one shown in Japanese Patent No. 38531 is known. This method involves tilting a hydroponic tank filled with gravel, plastic particles, etc. to grow wasabi. This is a method of cultivating wasabi by flowing the water back into the tank.

(Problems to be solved by the invention) In such conventional methods, no measures are taken against the above-mentioned viral diseases and bacterial diseases, and therefore there are problems such as a decline in the quality and productivity of wasabi. was there.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and in addition to being able to accurately control water quality in the artificial cultivation of wasabi, there are also restrictions on region and climate. To provide a method and device for cultivating wasabi of high quality and high productivity, which can shorten the growing period compared to natural wasabi without being damaged by wasabi, prevent the occurrence of diseases caused by viruses and bacteria, and have high productivity. With the goal.

In order to achieve the above object, the cultivation method according to the present invention involves placing wasabi containing rhizomes in a culture net up to the bottom of the vibrator in a culture cylinder protruding from the top surface of the vibrator of a culture unit consisting of a pipe, and then cultivating a sterile culture containing fertilizer. The alkalinity and fertilizer concentration of the wastewater are selected in a check tank, and then bacteria are removed using a filter. After passing through an ion exchange tank, the water is cultured again as culture water set at a specified water temperature. It is characterized by circulating to the unit.

In addition, the cultivation device consists of a culture unit with a culture tube on the top of the pipe where the culture water flows, a check tank that stores wastewater and detects alkalinity, fertilizer concentration, water temperature, etc., and a check tank that collects bacteria in the wastewater. a filter that removes
The special feature is that it consists of an ion exchange tank and a heating device for setting the water temperature.

(effect) The present invention configured as described above operates as follows.

The wasabi grown in each culture unit is cultivated between independent cultures, making it possible to prevent the transmission of viral and bacterial diseases.

<Example> FIG. 1 is an overall view of a cultivation apparatus showing an example of the present invention, and FIG. 2 is an enlarged sectional view of a cultivation unit. In the figure, A is a culture unit consisting of a plurality of pipes 1, and B is a culture unit consisting of a single vibrator 1 connecting the culture units A.

These culture units A and Snake are made by connecting pipes 1 made of plastic with elbows and sockets 2,
Culture tubes 3 are integrally provided on the upper surface of each vibrator 1 at predetermined intervals and communicate with the inside of the pipe 1. Further, the surface of each vibrator 1 is coated with a heat insulating material 4, and a ventilation hole 5 is opened in the culture tube 3.

A constant amount of culture water 6 flows through the vibrator 1 so that an air layer exists above the vibrator 1, and a baffle plate 7 is fitted into the vibrator 1 so that the predetermined amount of water is 1q.

Wasabi 10 with rhizomes 9 placed in a cylindrical culture net 8 is accommodated in each culture cylinder 3 of culture units A and B and cultured. There are two ways to carry out this culture, one is to place the rhizomes 9 directly into the culture net 8, and the other is to place the rhizomes 9 into the culture net 8 with a filler 11 made of a molded product such as perlite or diatom. There is something. In the former case, rhizome 9
In the latter case, the rhizome 9 is made to float from the culture water 6. That is,
In the latter case, the filler 11 supplies the rhizome 9 with the nutrient water 6 drawn up by capillary action.

12 is a check tank in which the waste water of the culture water 6 from the final culture unit A is stored by the aerator 13. It is equipped with a control sensor 14 to prevent poisoning and check for inhibitors accumulating during circulation, and in the check 1112 there is a supply pipe 16 for replenishing fertilizer from a fertilizer tank 15.

17 is a water tap, and 17a is a drain plug.

A drain pipe 18 is connected to the check tank 12, and this drain pipe 18 is connected to a suction pump 19 and a filter 201 for removing bacteria and other impurities from the waste water.Ion exchange 1 for removing the above-mentioned inhibitors! 21. Furthermore, a heat exchanger 22 is connected to keep the water temperature at a predetermined temperature, and the waste water discharged from the heat exchanger 22 is returned to the culture unit A from the supply pipe 23 as culture water 6. In addition, in the present invention, the alkalinity in the culture water is set to pH 6.3 to 7.3 (D for bacteria prevention) -14 to 3.5), and the water temperature is set to 12°C ± 1°C.
and the temperature inside the house where this device is installed is 20~20~
A humid condition of 25°C is recommended.

24 is a lighting device that provides artificial light of 2,000 to 3,000 lux, and the lighting time is controlled by a timer.

The method for cultivating wasabi according to the present invention is to flow culture water 6 into culture units A and B consisting of a vibrator 1, and the wasabi rhizomes 9 in the culture net 8 directly absorb nutrients from the flowing culture water 6. Alternatively, they grow by absorbing nutrients from the culture water 6 sucked in by the filler 11. Culture units A, B
The wastewater that has passed through is temporarily stored in the check IW 12, where the alkalinity, water temperature, fertilizer concentration, and inhibitors in the wastewater are controlled.When there is a shortage of fertilizer, the fertilizer tank 15 is used. In addition to receiving Li supply, the water temperature is adjusted by a heat exchanger 22, and the inhibitor is an ion exchange IW.
It is removed in 21. Further, bacteria such as bacteria and other impurities in the waste water are removed by the filter 20. The wastewater thus passed through the heat exchanger 22 and maintained at a predetermined water temperature is supplied to the culture units A and B again as culture water 6.

In the wasabi cultivation apparatus configured as described above, wasabi 10 is independently cultivated in the cultivation units A and B, and especially in the cultivation of wasabi in which the filler 11 is housed in the cultivation net 8. Since the culture water 6 supplied to the filling material 11 does not fall down once it has been sucked up, the transmission of viruses, etc. to other wasabi 10 can be prevented. In addition, by creating a space between the ventilation holes 5 in the culture tube 3 and the culture tube 3,
The healthy growth of rhizomes 9 can be achieved by suppressing unnecessary hair root growth. Furthermore, the vibrator 1 of culture units A and B is insulated with VJ4.
Since it is coated with water, there is almost no fluctuation in water temperature.

In addition, in the present invention, the culture tank 25 may be provided in the middle of the piping 24 of the culture units A and B.

As shown in FIG. 3, this culture tank 25 receives culture water 6 from a water supply pipe 26 and returns it to a pipe 28 from a discharge pipe 27.Furthermore, a support rod 29 is passed into the culture tank 25. The culture net 8 is supported by hooks 8a and suspended. Note that the inside of the net 8 may be used with or without the filler 11 depending on the need.

(Effects of the Invention) As explained above, the present invention uses a circulating culture water system, so there is very little water usage, and water quality can be accurately controlled without being restricted by region, climate, or location. However, the growing period is 2/3 to 1.5 times longer than that of natural plants. /2.

In addition, it prevents the occurrence of diseases caused by viruses and bacteria, and produces wasabi of high quality and high productivity. Further, in the cultivation apparatus of the present invention, since the cultivation unit consists of a pipe connection, there are advantages such as the ability to freely change the scale and form of the cultivation unit.
