TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for forcing cultivation of cod roe using deep ocean water as a medium solution and a medium solution thereof.
[0002]
[Prior art]
Taranome is one of the main items of wild vegetable production, and is produced about 500 tons annually nationwide. In the forcing cultivation of taranome, the branches of the arboretum grown in the open field are cut off from the root of the plant, cut at each side bud, inserted into a well-watered medium, and sprouted at an early stage using a warming and moisturizing facility. It is a cultivation method. Tap water and groundwater are used for irrigation. Forcing cultivation of cod roe is carried out, for example, at a minimum soil temperature of 18 ° C. and a humidity of about 85%.
[0003]
[Problems to be solved by the invention]
In the case of the above-mentioned conventional technology, forcing cultivation of taranome is carried out under conditions of a minimum ground temperature of 18 ° C. and a humidity of about 85%, so that pathogenic bacteria are likely to be generated, and if the growing period is prolonged, gray mold will develop. Causes increased spoilage and reduced yield. In addition, when forcing is started early in the winter, the arbor is still in a dormant state and the germination is not good. Therefore, conventionally, a growth regulator is used to break dormancy, and a germination promoting treatment is performed. However, in recent years, the use of growth regulators is difficult and not preferable due to stricter regulations on pesticides and the like and consumers' preference for pesticide-free. Therefore, a new harmless natural substance that promotes the germination of taranome is required.
[0004]
The present invention has been made in view of the above-mentioned conventional problems, using a substance harmless to the human body, promotes the germination and growth of taranome, forcing cultivation method of taranome to suppress the occurrence of putrefaction buds and its culture medium It is intended to provide a solution.
[0005]
[Means for Solving the Problems]
The present invention relates to a method for forcing cultivation of taranome, in which the lateral buds of a citrus tree are inserted into a forcing bed, and the deep sea water is diluted 80 to 120 times with water as a medium solution, and preferably, a diluted solution diluted to 100 times is irrigated on the forcing bed. It is.
[0006]
The present invention also provides a medium solution for forcing cultivation by inserting side buds of a citrus tree in a forcing bed, wherein the deep sea water is diluted 80 to 120 times, preferably 100 times, with deep water. Medium solution. Instead of the deep sea water, an aqueous solution such as nitrate nitrogen having a composition close to that of the deep sea water may be used. In this case, an aqueous nitrate nitrogen solution having a concentration of 10 to 120 times the concentration of nitrate nitrogen contained in the deep sea water is used.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. In this embodiment, as shown in FIG. 1, a scion of the agaricus is cut off from the root of the agaric tree, and the agarician tree 14 cut for each bud of the lateral bud is inserted in the forcing bed 12 side by side. The forcing floor 12 is made of, for example, rock wool. Then, as a medium solution, a diluted solution obtained by diluting deep sea water with water 80 to 120 times, preferably 100 times, is prepared and sufficiently irrigated.
[0008]
The deep-sea water used here is a deep-sea water intake facility in Toyama Prefecture, which is collected from the deep sea of Toyama Bay at a depth of 200 m or less. This deep water has an average concentration of nitrate nitrogen of 0.26 mg / l, which is higher than the average concentration of nitrate nitrogen of sea surface water of 0.04 mg / l, and potassium also has an average concentration of 374 mg / l of deep water. Whereas surface water is slightly higher with an average of 356 mg / l. In addition, salinity and other components have almost the same value in both deep water and surface water. The cultivation conditions of taranome are a minimum ground temperature of 18 ° C. and a humidity of about 85%. Then, the taranome generated from the side buds is harvested as needed.
[0009]
According to the forcing cultivation method of the taranome of this embodiment, nitrate nitrogen and the like in the deep sea water effectively act on the germination and growth promotion of the taranome, and it is possible to greatly increase the yield of taranome and shorten the days of forcing. Production is improved. In addition, by shortening the promotion days, it is possible to ship at a time when the unit price is high in anticipation of the seasonal feeling, and high profits can be expected. In addition, as compared with the conventional method using water, the generation of spoilage and sprout of cod roe is suppressed. This contributes to the stable management of producers.
[0010]
In addition, by using the deep ocean water at an appropriate concentration, the growth can be effectively used without inhibiting growth due to salt content. It shows the possibility of applying deep ocean water to various kinds of wild plants such as taranome, and new applications of deep ocean water can be expected. In addition, the use of deep ocean water for agriculture and forestry can be opened.
[0011]
And it is possible to supply high quality and highly safe taranome. In today's highly health-conscious, high market potential can be expected as a safe and secure mountain vegetable using deep ocean water. Safe and high-quality taranome that does not contain harmful chemical substances such as pesticides is supplied, and the market can be expected to expand, which also leads to stable management of taranome producers. In particular, deep ocean water is cleaner and easier to handle than surface water, and is suitable as irrigation for forcing cultivation.
[0012]
In addition, the forcing cultivation method of the taranome of the present invention is not limited to the above embodiment, in the medium solution forcing cultivation by inserting the side buds of the arboretum on the forcing floor as in the above embodiment, for example, in Toyama Bay A nitrate nitrogen aqueous solution having a concentration of 10 to 120 times the concentration of nitrate nitrogen (0.26 mg / l) contained in deep sea water may be used.
[0013]
In addition, it can be used for cultivation other than taranome. The type of culture medium and the conditions for cultivation can be appropriately changed, such as the minimum soil temperature and humidity. Further, instead of the deep ocean water, a nitrate nitrogen aqueous solution or an aqueous solution of various salts having a composition close to that of the deep ocean water may be used as a medium for promoting cultivation, as described above.
[0014]
【Example】
Next, the forcing cultivation method of cod roe of one embodiment of the present invention will be described in detail along with comparative examples. First, as a medium solution for forcing cultivation of cod roe, a deep sea water stock solution taken at a depth of 200 m or less in Toyama Bay, a 10-fold diluted solution, a 100-fold diluted solution, and a saline solution corresponding to the amount of sodium chloride (3 0.2%, 0.3%, 0.03%) and distilled water. The minimum ground temperature was set at 18 ° C. with an electric heating hotbed (100 w / m 2) in a glass room, and tunnel covering was performed with a polyethylene film. Watering was performed with each medium solution as needed until the harvest was completed.
[0015]
As a result, when a 100 times dilution of deep sea water was used, as shown in FIG. 2, the cumulative yield rate indicating the yield was as high as 94%, and the saline and distilled water having a salt concentration of 0.03% were used. It was possible to achieve a yield increase of about 15%, exceeding the cumulative harvest rate of each case. This is presumably because, when a 100-fold diluted deep seawater solution was used, growth inhibition due to salt content did not occur and, as shown in FIG. 3, the generation of putrefaction buds could be suppressed. For example, in order to obtain a cumulative harvest rate of 80%, it takes about 30 days when 0.03% saline and distilled water are used. In about 20 days, this was achieved in about 20 days, and the number of days for promotion was greatly reduced.
[0016]
This means that when cultivated in deep ocean water, as shown in FIG. 4, the inorganic nitrogen concentration in the buds of taranome is lower than that of distilled water and saline, and nitrate nitrogen and other nitrogen in deep ocean water. This is probably because minerals and the like are working effectively to promote growth.
[0017]
Here, the growth situation on the 17th day of forcing cultivation is shown in FIG. In FIG. 1, rock wool of the forcing bed 12 is put in the cultivation container 10, and the arachis tree 14 is cut and lined up for each side bud on the forcing bed 12. Then, the cod roe 14 is provided with cod roe 16 in which buds have grown. FIG. 1 (a) shows a medium using a 100-fold diluted solution of deep sea water as a medium solution, FIG. 1 (b) shows a stock solution of deep sea water, and FIG. 1 (c) shows a solution using distilled water. According to this, in comparison with FIG. 1 (b) using the deep sea water stock solution and FIG. 1 (c) using the distilled water, the one in FIG. It can be seen that 16 germination and growth are good. In addition, in FIG. 1 (b) using the deep seawater undiluted solution, it can be seen that the growth of the agaricus 16 is more inhibited than in FIG. 1 (c) using the distilled water due to the salt concentration and the like.
[0018]
Also, as described above, nitrate nitrogen seems to have a large effect on the forcing cultivation of codfish, so deep seawater stock solution, 10-fold diluted solution, 50-fold diluted solution, 100-fold diluted solution, 200-fold diluted solution, Forcing cultivation in the same manner as described above using a 500-fold diluted solution, a 1000-fold diluted solution, and distilled water, and an aqueous solution whose nitrate nitrogen concentration is 10 times, 100 times, or 500 times the deep sea water. Was conducted.
[0019]
As a result, as shown in FIG. 5, when the nitrate nitrogen aqueous solution corresponding to 10 times the deep sea water and 100 times the deep sea water was used, the cumulative yield was 80% or more, and good results were obtained. On the other hand, when an aqueous nitrate-nitrogen solution equivalent to 500 times the depth of the deep sea water was used, the number of days for promotion was slightly earlier than that of distilled water. In addition, when a nitrate-nitrogen aqueous solution equivalent to 10 times the depth of the deep sea water was used, a relatively high harvest rate was exhibited at an early stage of the forcing period, and the harvest was almost stopped at about 80% in about 25 days. This seems to have had a favorable effect on forcing culture due to the high nitrate nitrogen concentration. On the other hand, the 100-fold diluted deep-sea water does not reach the nitrate-nitrogen aqueous solution equivalent to 10-fold deep-water until the forcing period is around 20 days, but the 100-fold diluted deep-sea water shows a yield of 90% or more. Other components of the deep sea water may contribute to the improvement of the yield.
[0020]
【The invention's effect】
In the forcing cultivation method of the present invention, nitrate nitrogen and the like in deep sea water effectively act on the germination and growth of the taranome, and it is possible to greatly increase the yield of the taranome and shorten the number of days for forcing. By using a liquid obtained by diluting the deep sea water 80- to 120-fold, growth inhibition due to salt does not occur, and the effective components of the deep sea water greatly contribute to forcing cultivation. Further, by using an aqueous solution having an appropriate concentration of nitrate nitrogen for the medium solution for forcing cultivation, forcing cultivation can be made more efficient.
