DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the present invention will be described.

The present embodiment relates to a method for cultivating fresh vegetables using Kaiwa radish as fresh vegetables.

FIG. 1 is a flow chart (hereinafter referred to as a conventional example) showing a conventional conventional method for cultivating radish, and FIG. 2 is cultivation of radish including a sterilizing step of radish. 5 is a flowchart illustrating a method (hereinafter, referred to as a present embodiment).

The germicide used in this embodiment is fumaric acid.

[0032] The seeds of dried radish radish are heated to about 25 ° C.
In water for 7-8 hours.

At this time, in order to sterilize the seeds of the Japanese radish, the seeds of the Japanese radish are impregnated with a fungicide so as to reach a predetermined concentration. In this example, since fumaric acid was used as a bactericide, the seeds of radish radish were added at a concentration of 4%.
% (Weight) fumaric acid solution (ethanol 70-75%
(Including 0.05% (by weight) and ascorbic acid (by weight)) for 1 to 5 minutes to impregnate the seeds of the Japanese radish with fumaric acid, and then immerse the seeds of the Japanese radish in water. The concentration of the fungicide and the impregnation time are set within a range that can surely sterilize the seeds of the Japanese radish and that do not affect the germination rate of the seeds of the Japanese radish.

Subsequently, the seeds of the Japanese radish are drained, placed in a germination room (dark room at 25 ° C.) and left until the next morning to germinate the seeds of the Japanese radish.

Subsequently, the seeds of the germinated cauliflower radish are sowed in a certain amount in a cultivation container with a sowing machine, and water is sprinkled once.
In addition, an aqueous solution of fumaric acid (preferably at a concentration of 0.2% (by weight) or more so that O-157 can be effectively sterilized) may be used to sterilize the radish during watering.

Subsequently, the cultivation container containing the seeds of the germinated cauliflower radish is transported from the germination chamber to the cultivation bed, and the cultivation beds are arranged in multiple stages vertically, horizontally, and grow to a size that can be shipped as a product (usually 4 to 4). It takes five days.) At this time, water is sprinkled two to three times a day. At the time of sprinkling, an aqueous solution of fumaric acid (O-1) is used to sterilize the Japanese radish.
0.2% (weight) to effectively sterilize 57
The above is desirable. ) May be used.

Subsequently, the grown radish is extracted from the cultivation container by a predetermined amount (one pot), and the radish is sterilized and washed with a fumaric acid solution and further washed with water. The fumaric acid solution used is desirably at a concentration of 0.2% (by weight) or more so that O-157 can be effectively sterilized. The fumaric acid solution penetrates into the inside of the radish and the inside of the radish It is desirable that the radish be immersed in the fumaric acid solution for 30 minutes or more so that O-157 attached to the water can be sterilized.

Subsequently, the grown cabbage radish is filled in a pot for sale by an automatic sealing machine, and the pot for sale is stored in a shipping cardboard, pre-cooled in a refrigerator and shipped.

In this embodiment, as described above, the seeds of the Japanese radish can be sterilized along the production process of the conventional example.
Thus, the present invention provides a method for cultivating Kaiwai radish, which is excellent in practicality and workability, capable of producing safe Kaiware radish free of bacteria such as -157.

When the seeds of the Japanese radish are sterilized, the concentration and time of the fungicide are set so as not to affect the germination rate of the seeds of the Japanese radish. This is a method for cultivating radish with high productivity without loss in the germination process.

Further, when water is sprayed on the radish during the growth process of the radish, the radish can be sterilized by using an aqueous solution of a bactericide instead of water. The cultivation method of Kaiware radish excelling in practicality and productivity, which can enhance the safety of Kaiware radish without it.

In the shipment process of the radish,
Since the radish is sterilized with a bactericide, O-157
It is a practical method of cultivating Kaiwai radish that can be shipped safely without being contaminated with bacteria.

An experimental example supporting the operation and effect of this embodiment will be described below.

The fungicide used in this experimental example is fumaric acid, and the method for measuring O-157 is based on the method for testing pathogenic Escherichia coli O-157 shown in FIG. (Medical National Health Insurance Section) Ethyl alcohol was used as the alcohol to be used without any adverse effect on the human body.

<First Experimental Example> The bactericidal effect of fumaric acid on O-157 is greatly affected by the concentration (Japanese Patent Application Hei 9
According to -104961, the concentration is 0.2% (weight) or more. In the case of sterilizing the seeds of the Japanese radish, the water absorption rate and the water absorption rate of the seeds of the Japanese radish are important.

2 g of dried seeds of Japanese cabbage radish were added to 100 m of water.
1 for 14 hours, and over time, lightly drained seeds are weighed and the water absorption is determined from the weight difference, and the water absorption rate for each immersion time is determined from the weight difference based on the maximum water absorption at 14 hours immersion. Table 1 is obtained.

[Table 1] Thus, the water absorption rate of dried radish to dried seeds is
It is so fast that the water absorption becomes 31.3% after immersion for one hour. Therefore, when the seeds of the Japanese radish are immersed in the fumaric acid solution for one hour, the total weight of the seeds of the Japanese radish is adjusted in order to make the concentration of fumaric acid in the seeds of the Japanese radish 0.2% (weight) or more. : Weight of fumaric acid solution = 100: 3
1.3, the concentration of the fumaric acid solution used is:
0.2 × 100 設定 31.3 = 0.64% (weight) or more.

From the above results, it is necessary to appropriately set the concentration of fumaric acid according to the sterilization time when the seeds of the Japanese radish are sterilized with the fumaric acid solution, and after immersing water in the dried seeds of the Japanese radish. It can be seen that an attempt to sterilize with a fumaric acid solution requires the use of a very high concentration fumaric acid solution.

Therefore, when the seeds of the Japanese radish are sterilized by immersing the seeds of the Japanese radish, the bactericidal action of the fumaric acid solution is exhibited in a sterilization time of about 1 minute. After soaking, it is desirable to continue the soaking operation with water.

<Second Experimental Example> When seeds of the Japanese radish are sterilized, the germination rate is reduced, and there is a possibility that germination operation may be lost.

A 4.0% (weight) fumaric acid solution (about 75% (weight) of alcohol concentration and about 0.05% (weight) of ascorbic acid as a stabilizer) is added to 2 g of the seed of radish. 0.2% (by weight) fumaric acid solution, 0.3% (by weight) fumaric acid solution and 4.0% obtained by dilution
(Weight) Fumaric acid solution (Alcohol concentration 70% (Weight)
About 0.05% (weight) of ascorbic acid as a stabilizer
Has been added. ) Was washed with 40 ml for a predetermined period of time, and the seeding process was performed with water for a total of 8 hours, the water absorption was determined from the weight after draining, and the seeds of the radish were left overnight in a dark room at 25 ° C. The germination rate was determined by examining the germination status, and Table 2 was obtained.

[Table 2] Thus, the higher the concentration of fumaric acid, the lower the germination rate of the seeds of the Japanese radish, the higher the concentration of fumaric acid.
% (Weight) fumaric acid solution for 2 hours, 0.3% (weight)
It can be seen that the fumaric acid solution takes about 1 hour and the 4.0% (by weight) fumaric acid solution takes about 10 minutes.

Therefore, when the seeds of the Japanese radish are germinated by the seeds of the Japanese radish along the seeding step, it is desirable to perform the sterilization operation within the sterilization time within the range not affecting the germination rate as described above.

<Third Experimental Example> In order to examine the bactericidal effect on O-157 during the washing time without affecting the germination rate,
10 The dry seeds of radish sprouts ^four orders of O-157
The soybean radish seeds were immersed in 40 ml of the culture solution for 5 minutes, and the seeds of the Japanese radish were washed with a fumaric acid solution having a predetermined concentration for a predetermined time.
I got

[Table 3] As described above, in a 4.0% (weight) fumaric acid solution, O-157 can be sterilized to 10 or less in a washing time of 1 minute.

However, 0.2% (weight) and 0.3%
(Weight) of fumaric acid solution, O-15 can be effectively used in a washing time that does not affect the germination rate of the seeds of radish.
7 could not be sterilized.

The reason for this is that, even after washing with a 0.3% (weight) fumaric acid solution for 60 minutes, the fumaric acid concentration in the seeds of the Japanese radish is 31.3 × 0.3% according to Table 1 above. 1
00 = 0.09% (weight), which is considered to be due to the fumaric acid concentration not reaching the effective sterilizing concentration of 0.2% (weight).

Therefore, when the seeds of the Japanese radish are sterilized with a fumaric acid solution, the fumaric acid solution used is used in order to bring the fumaric acid concentration in the seeds of the Japanese radish to an effective sterilizing concentration (0.2%). Is set to 0.2 × 100 ÷ 13.
6 (water absorption in 1 minute capable of sterilizing O-157) =
It is presumed that setting it to 1.47% (weight) or more is desirable.

<Fourth Experimental Example> In order to examine the results of the third experimental example in more detail, according to the third experimental example, dried seeds of radish were immersed in 40 ml of O-157 culture solution for 5 minutes.
The seeds of the radish were washed with a fumaric acid solution having a predetermined concentration for a predetermined time, and the number of bacteria was measured for the washed seeds of the radish. Table 4 was obtained. Also, after washing the radish, perform a seeding step with water for a total of 8 hours.
The germination rate was determined according to the second experimental example, and Table 5 was obtained.

[Table 4]

[Table 5] Thus, in the washing step with the fumaric acid solution at the time of the soaking step, the higher the fumaric acid concentration, the lower the germination rate of the seeds of the Japanese radish, and the limit is 0.3%
(Weight) is 60 minutes (the upper limit is unknown in this experimental example), 0.5% (weight) is 15 minutes, and 1.0 to 1.0%.
At 4.0% (weight), it takes about 5 minutes.

Regarding the bactericidal action of the fumaric acid solution, a bacteriostatic effect is obtained at a rate of 1.5% (weight) or more in a washing time of 5 minutes or 2.5% (weight) or more in a washing time of 1 minute. At 4.0% (by weight), a complete bactericidal effect is obtained.

In order to obtain a high-concentration fumaric acid solution, a large amount of alcohol must be added, but no bacteriostatic and bactericidal effects could be confirmed with this alcohol.

Therefore, in order to completely sterilize the seeds of the Japanese radish, it is desirable to use a fumaric acid solution having a concentration of 4% (by weight) or more.

It is to be noted that, in the third experimental example, it is estimated that an effective bactericidal effect is obtained when the concentration of fumaric acid is 1.47% (by weight) or more, and the reason why the result obtained in the fourth experimental example is different. The sterilization time is too short, the fumaric acid solution cannot reach the center of the seeds of the radish, and the fumaric acid solution cannot reach the center of the seeds of the radish. O-157 attached to
It may be possible that the fumaric acid component could not be sterilized or that the fumaric acid component of the fumaric acid solution could not penetrate the seeds of the radish.

<Fifth Experimental Example> The sterilization effect of the fumaric acid solution on the grown Japanese radish was confirmed in order to ensure the safe shipment of the Japanese radish without contamination by O-157.

50 g of the harvested radish was immersed in 300 ml of a 10 ⁴ order O-157 culture solution for 30 minutes.
The dried radish was washed with a fumaric acid solution having a concentration of 0.2% (by weight) for a predetermined time, and the number of bacteria of the washed radish was measured.

[Table 6] Thus, by washing with a 0.2% (weight) fumaric acid solution for 30 minutes or more, O-157 can be sterilized to 10 or less.

Therefore, the radish radish before shipment has a concentration of 0.
By sterilizing and washing with a fumaric acid solution of 2% (by weight) or more for 30 minutes or more, it is possible to surely ship safe radish free of O-157 contamination.

The results of the fifth experimental example suggest that the 0.2% (by weight) fumaric acid solution can reliably sterilize O-157 adhering to other fresh vegetables such as cabbage other than cauliflower radish. I have.

<Sixth Experimental Example> The commercial value of the grown Kaiwa radish when sterilized with a fumaric acid solution is confirmed.

After harvesting, 50 g of Japanese cabbage radish was added at a concentration of 0.2.
% (Weight) of a fumaric acid solution for a predetermined time, and the washed radish is washed with water to obtain a color tone (chlorophyll a,
b) was measured, and Table 7 was obtained. The color was eluted with 0.5 g of sea sand and acetone from 1 g of the leaf portion of the radish radish, then diluted to 50 g with acetone, and the wavelength was 420 μm.
(Chlorophyll a) and absorbance at a wavelength of 460 μm (chlorophyll b) were determined.

[Table 7] Thus, even if the Japanese radish is sterilized with the fumaric acid solution, the color tone of the Japanese radish does not have any effect.

Further, even when an experiment was conducted on the taste of the washed radish (significant difference by the selection method), the difference was hardly felt.

Therefore, even if the grown radish is sterilized with a fumaric acid solution, its commercial value does not decrease.

The results of the sixth experimental example suggest that the use of a fumaric acid solution (aqueous solution) in place of watering water in the growth process of radish does not reduce its commercial value. doing.

<Seventh Experimental Example> The results of the fifth experimental example indicate that the fumaric acid solution can reliably sterilize O-157 adhered to other fresh vegetables such as cabbage other than cauliflower radish. However, in order to confirm this point, O-15 of fumaric acid solution
7 sterilization experiments were performed.

About lettuce, cauliflower radish, cabbage, cucumber, carrot, radish, pepper, onion, and onion
Each was immersed in a culture solution of O-157 for 30 minutes, then air-dried for 3 hours, washed with a fumaric acid solution (equivalent to that used in the second experimental example) for 30 minutes, and the number of bacteria was immediately measured.
Table 8 was obtained.

[Table 8] As described above, the bactericidal effect of the fumaric acid solution on O-157 was extremely excellent in all of the fresh vegetables.

When the fresh vegetables were washed with a fumaric acid solution and then washed with water for a predetermined time, the taste was examined (similar to the sixth experimental example, due to the significant difference by the selection method). Although the washing time was different, fresh vegetables which were not different from the taste of each fresh vegetable itself could be obtained by washing with water for 1 to 10 minutes. Therefore, the commercial value of fresh vegetables is not reduced by washing the fresh vegetables with a fumaric acid solution.

As described above, the experimental results of the seventh experimental example suggest that a similar good effect can be obtained even if the sterilizing method (and the cultivation method) according to the present example is applied to fresh vegetables other than the Japanese radish. doing.

To summarize the results of the above experimental examples, when the seeds of the Japanese radish are sterilized with a fungicide (fumaric acid solution), the concentration of the active ingredient in the seeds of the Japanese radish becomes a problem, and the growth of the Japanese radish becomes problematic. In the process,
It is preferable to provide a step of impregnating the seeds of radish with a fungicide as a preceding stage of the seeding step. When a solution is used as a disinfectant, it may be included in the seeding step. When a fumaric acid solution is used as a bactericide, the concentration is preferably set to be 0.2% (weight) or more in the seeds of radish.

When disinfecting the seeds of the Japanese radish with a fungicide (fumaric acid solution), the germination rate of the seeds of the Japanese radish becomes a problem. The problem of germination rate is solved. When using a fumaric acid solution as a bactericide,
It is preferable to immerse in a fumaric acid solution having a concentration of 4% (by weight) or more for 1 to 5 minutes.

Even if the radish is washed with a fumaric acid solution, the commercial value of the radish does not decrease. still,
Unlike seeds, when disinfecting the grown radish, the concentration of the fumaric acid solution may be set to 0.2% (weight) or more.

Fresh vegetables such as lettuce, cabbage, cucumber, ginseng, radish, peppers, onions, and onions other than kaiware radish can be sterilized with a fumaric acid solution in the same manner as kaiware radish to produce bacteria such as O-157. Can be shipped as safe fresh vegetables without contamination.
