Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sprouts cultivation method.
[0002]
[Prior art]
Conventionally, sprouts seeds are cultivated in large quantities under a well-maintained environment suitable for mass production by giving a large amount of nitrogen fertilizer by a conventional cultivation method.
Also, mass-produced sprouts on the market are not safe and rather unhealthy. The taste is not good, the taste and aroma as spices are low, and sometimes a scent smells.
In addition, sprouts are grown and harvested using chlorine sterilants and large amounts of water.
[0003]
[Patent Document 1]
Japanese Patent No. 1651458 [Problems to be Solved by the Invention]
When sprouts produced by the conventional cultivation method are immersed in water for 2 to 3 days, white mold is generated on one side and cultivation cannot be continued often. When a fungicide is used to prevent mold, there is a problem in that anxiety is caused in terms of hygiene and safety and the taste is remarkably reduced. In addition, when mass-produced, there is a disadvantage that the fermentation occurs due to heat generation and the product is easily rotten.
Since sprouts use a large amount of nitrogen fertilizer for cultivation of seeds, the content of nitrite nitrogen and nitrate nitrogen (nitrate) in the sprouts increases, the taste becomes poor, and there is a problem in terms of safety.
[0004]
[Means for Solving the Problems]
An object of the present invention is to make it possible to cultivate safe and delicious sprouts inexpensively and easily on a kitchen or a dining table at home.
The present inventor has found that when cultivating sprouts using seeds of a crop obtained by the cultivation method according to the invention of the present inventor (Patent No. 1651458), these drawbacks do not occur, sterilization is not required, and vitamin C It has been found that nutrients are high, and a safe and delicious sprouts can be obtained.
[0005]
The cultivation method of the patent is a cultivation method in which a crop is cultivated in a field with little fertilizer, no water and no pesticide, which is usually referred to as “Nagata farming method”. 2) After germination or planting, cut off water and nitrogen fertilizer. (3) If the crop begins to wither on a thin land where water and nitrogen fertilizer is cut off, a small amount of about 1/10 to 1/100 of the customary (plowing method) Cultivation method of giving high water and nitrogen fertilizer and repeating the operations of (4), (2) and (3) to produce fasting roots with strong water absorption and fertilization near the ground surface to harvest high vitamin C crops It is.
[0006]
The present inventors have found that radish, red beans, mung bean, black mappe, alfalfa, broccoli, cauliflower, brussels sprouts, oily vegetables, buckwheat or herb seeds harvested by the cultivation method of the patent are particularly excellent for sprouts cultivation. Was.
[0007]
The sprouts cultivation method of the present invention comprises: (1) reducing the nitrogen content of the culture medium to eliminate soil fertility, (2) cutting off water and nitrogen fertilizer after germination or planting, and (3) cutting off the water and nitrogen fertilizer in a lean place. When the crop begins to wither, give a small amount of water and nitrogen fertilizer about 1/10 to 1/100 of the conventional (plowing method), and repeat the operations of (4), (2) and (3) and near the ground surface Radish, red bean, mung bean, black maple, alfalfa, broccoli, cauliflower, brussels sprouts, oily vegetables, buckwheat or sprouts using the cultivation method of crops that produce fasting roots with strong water absorption and fertilizing power Cultivation is characterized by obtaining a safe and delicious sprouts without the need for sterilization, rich in vitamin C and nutrients.
[0008]
The sprouts cultivation container can be formed from paper, woven fabric, non-woven fabric, plastics, glass or ceramics into any suitable shape suitable for cultivation.
The cultivation container may or may not contain the medium. When accommodated, the thickness of the medium is preferably about 3 cm or less. It is preferably about 20 mm or less depending on the cultivation container. For example, when sprouts are cultivated in a tofu container or the like, the thickness is about 10 to 20 mm.
[0009]
After soaking the seeds in water, they are sown on a medium, net or perforated midsole.
When a thin net is placed on the medium and seeded from above, the sprouts after growth can be easily separated from the medium. The same applies to seeding on a net or a perforated midsole.
The net is preferably a thin metal net, particularly a thin stainless steel net.
After sowing, a covering sheet such as newsprint moistened with water is put on.
The coated sheet may be moistened by spraying with water occasionally so as not to dry.
The seeds covered with the covering sheet are preferably placed in a dark box or covered with a light-impermeable cover. After removing the shading cover, Futaba turns green in about half a day.
The medium is preferably cultivated with sand, and the particle size of the sand is preferably about 0.75 to 5 mm.
The sand is particularly preferably Yoshinogawa sand, and particularly preferably contains a small amount of iron.
After germination, it can be collected arbitrarily at any time and made edible.
[0010]
Effect of the Invention
The seed of the crop used in the present invention is not a hybrid of the first generation (F1) because it is not obtained by genetic engineering.
If sand is not used for the medium and nitrogen fertilizer is not applied, the bean sprouts will not generate heat and will not rot.
[0011]
【The invention's effect】
A simple container can be used for the sprouts cultivation container. For example, it is like a container of tofu.
Even if the seeds are immersed in water for 1-2 days, no white mold grows.
Sprouts roots can be easily separated from the medium.
It does not require chlorination to sterilize 0-157 bacteria.
Does not require a large amount of washing water. Nutrients do not run away, because they can be sufficiently washed by spraying a small amount of washing water.
It can be produced at low cost.
Easy to produce before meals.
Easy to store and move.
Ideal for kitchen gardens and kitchen gardens.
The sprouts obtained according to the present invention are of good quality, rich in vitamin C and other nutrients, are safe, have good sunshine and are delicious. The savory taste is emphasized for kairena and the like, making it the best salad or sashimi "tsuma".
[0012]
【Example】
Hereinafter, the present invention will be described in more detail with reference to examples.
[Examples 1 to 4]
Seeds of Japanese radish cultivated and harvested by the cultivation method of Japanese Patent No. 1651458 were immersed in water for 3 hours, and then sown in an empty container A of tofu and a container B with an insole 25 ml each. For sowing, many drain holes were opened at the bottom of the empty container A of tofu, and coarse sand mixed with weathered pebbles of granite was added as a medium to a thickness of about 10 mm, and a wire mesh was placed on the seeding. (See FIG. 1). The container B with an insole has an insole made of unglazed pottery with many holes (with legs) placed on the bottom of the container, and the insole has a peripheral edge with a height of about 3 to 5 mm around the periphery. (See FIG. 3), and the seeding was performed directly on the upper surface of the middle bottom without using a medium. Seeds did not flow out of the insole provided with the peripheral edge even when water was injected and replaced. After sowing, the newsprint was cut and covered with moistened coated paper and placed in a dark box. Thereafter, water was sprayed every morning until the morning of the sixth day.
[0013]
On the other hand, the seeds of a commercially available radish were similarly soaked in water for 3 hours, and then seeded in an empty container C of tofu and a glass container D for hydroponics in 25 ml each. In sowing, many drain holes were opened at the bottom of the empty container C of tofu, and coarse sand mixed with weathered pebbles of granite was added as a medium to a thickness of about 10 mm, and a wire mesh was placed on the seeding. did. The hydroponic glass container D supported a net with many holes formed in a plastics plate at a height of about 5 cm from the bottom of the container, sowed directly on the net, and filled with water to the bottom of the net. (See FIG. 2). After sowing, the newsprint was cut and covered with moistened coated paper and placed in a dark box. Thereafter, water was sprayed every morning until the morning of the sixth day. The water in the glass container D for hydroponics was replaced every morning.
[0014]
When the morning water was sprayed on the second day after sowing, almost all of the seeds in the empty container A of the tofu and the seeds in the container B with the insole had germinated to about 2 to 4 mm. About 3/4 of the seeds in the empty container C of the tofu and the seeds in the glass container D for hydroponics were germinated to about 2 to 4 mm. The coated newsprint was dry and was resprayed with water. The glass container D for hydroponics was replaced with water.
[0015]
The third day after sowing. The seed of the empty container A of the tofu and the seed of the container B with the insole extended to about 1 to 2 cm, and Futaba had begun to grow. As for the seeds of the empty container C of the tofu and the seeds of the glass container D for hydroponics, about ４ of the seeds were extended to about 1 to 2 cm, but some seeds did not germinate, and the surrounding area was like white fluff. Mold was partially visible. It easily fell off when washed with water. Seeds of the glass container D for hydroponics had roots extending about 2 cm into water.
[0016]
On the morning of the fourth day after sowing, the seeds in the empty container A of the tofu and the seeds in the container B with the insole had about 3/4 of the germinated seeds extended to about 3 to 4 cm. The seeds of the empty container C of the tofu and the seeds of the glass container D for hydroponics had about 3/4 of the germinated seeds extended to about 3 to 4 cm. Seeds of the glass container D for hydroponics had roots extending about 4 cm into water.
[0017]
On the morning of the fifth day after sowing, the seeds of the empty container A of the tofu and the seeds of the container B with the insole extended to about 5 to 6 cm. The seed of the empty container C of the tofu and the seed of the glass container D for hydroponics had about 3/4 of the germinated seeds extended to about 5 to 6 cm. The seeds of the glass container D for hydroponics had roots extending about 5 cm into the water. The seeds of the container D made of glass for hydroponics had good root growth in the water and good stem growth.
[0018]
On the morning of the sixth day after sowing, the seeds of the empty container A of the tofu and the seeds of the container B with the insole extended to about 6 to 7 cm. The seeds of the empty container C of tofu and the seeds of the glass container D for hydroponics had about 3/4 of the germinated seeds extended to about 6 to 8 cm. The seeds of the glass container D for hydroponics had roots extending about 5 cm or more into the water, and exhibited a root-wound state at the bottom of the container. Stem growth was also good.
[0019]
We harvested and sampled the afternoon of the sixth day.
The yield was in the order of tofu empty container A, inner bottomed container B, hydroponics glass container D, and tofu empty container C in descending order. The yields of the empty container C of tofu and the glass container D for hydroponics were small because the germination rate was as low as about 75%.
As a result of the tasting, the stalks of the empty container A of the tofu and the squid vegetable of the container B with the insole were thinner than those of the empty container C of the tofu and the container D made of glass for hydroponics, and the futaba was a little. It was small but had a more crisp taste, with a refreshing flavor and a crunchy texture. The tofu empty container C using commercially available seeds had an inferior taste and bitterness, and the glass container for hydroponics D had a watery, bitter taste and almost no tangy taste.
Next, buckwheat seeds cultivated and harvested by the cultivation method of Japanese Patent No. 1651458 were compared with commercially available buckwheat seeds, and substantially the same results were obtained.
