Nutrients (fertilizers) are essential for crop growth. When nutrients (fertilizer) suitable for crop growth are deficient, crop growth stops and causes death. On the other hand, if the nutrient (fertilizer) is excessive, the roots will be damaged, and the growth of the crop will atrophy and stop, and in severe cases it will die. In the agricultural field, this phenomenon is called continuous cropping disorder or concentration disorder.
According to the first plant cultivation method which is the premise of the present invention, a student who learns a plant cultivation subject and a teacher who teaches a student are able to understand that “the crop grows quickly, the nutrient is deficient and the green It can be observed directly, such as the appearance of the leaf color changing to yellow and withering, the appearance of not seeding even when seeded, and the appearance of the crop growing atrophizing and dying even after germination. . And we can learn from the basics that the relationship with "people, crops, environment" is important for crop cultivation. Furthermore, it has the effect of being able to “learn” and “create” based on failures and successful experiences and learn how to grow crops quickly.
Moreover, according to the 3rd plant cultivation method using the same cultivation pot and soil after cultivation of the crop by the 1st plant cultivation method, since the same cultivation pot and soil can be used, it is economical, 1st It is possible to grow the crops smoothly while confirming the knowledge obtained by the plant cultivation method, so that students and teachers can have a deep understanding of agriculture. And by sowing seeds with their own hands, managing the cultivation such as daily watering, you can enjoy the joy of growing the crops smoothly, and eating the harvested crops at school and at home You can also enjoy the joy of eating the grown crops.

According to the plant cultivation kit for education of the present invention, the above-mentioned plant cultivation method and the plant cultivation method using the same cultivation pot and soil after crop cultivation by the plant cultivation method can be easily executed, The burden on the teacher who teaches the students becomes easier, and the teaching effect in the plant training subject of the course of study described in the background art section is surely improved.
Although “local production for local consumption” is advocated in various places, making and eating fresh and safe agricultural products is the origin of “local production for local consumption” and is the best teaching material for food and agriculture education.

Furthermore, the learning effect by the third plant cultivation method using the same cultivation pot and soil after the first plant cultivation method and crop cultivation by the plant cultivation method is not limited to school education.
Even in the agricultural field, for example, when crops are cultivated in newly cultivated fields, nutrients (fertilizers) are deficient and yields are reduced. If the same crops are cultivated every year in the same fields, nutrients (fertilizers) are accumulated. Yield decreases.
By the first plant cultivation method and the third plant cultivation method using the same cultivation pot and soil after the crop cultivation by the plant cultivation method, the farmers, especially the newly entered farmers, deeply understand these causes. Measures to solve the decrease in yield, that is, apply organic fertilizer or eggshell to adjust the nutrient balance of the soil, or apply soil improvement materials for ventilation and water flow Can improve soil quality.

Recording paper used to observe the growth of crops. A label that gives a display to identify the cultivation conditions of the crop.

The first embodiment of the plant cultivation method and the embodiment for instructing so that the principle of biological growth can be firmly learned by the plant cultivation method are as follows.
1. Prepare multiple cultivation pots of the same shape and size.
2. Put soil without fertilizer in one of the cultivation pots, sow 100 seeds of the crop.
3. Put an appropriate amount of fertilizer suitable for the growth of the crops into a container such as a plastic bag, and mix the soil containing the fertilizer into one of the cultivation pots. Put 100 seeds of the crop.
Here, an appropriate amount of fertilizer suitable for growing crops is a fine chemical fertilizer containing nitrogen, phosphoric acid and potassium for about 1 liter of soil not containing fertilizer in the case of Komatsuna. It is about 5 to 10 g.
4). Put the soil containing no fertilizer and the amount of fertilizer that is not suitable for the growth of the crop in a container such as a plastic bag, and mix the soil containing the fertilizer into one of the cultivation pots. Put 100 seeds of the crop.
Here, the amount of fertilizer that is not suitable for the growth of crops is 15 g in the case of Komatsuna, if it is a fine chemical fertilizer containing nitrogen, phosphoric acid and potassium for about 1 liter of soil not containing fertilizer. More than about.
5. When the seeds of the crop are sowed, the state of the growth of the crop is observed at an appropriate interval, preferably at a fixed time every day, and a record is made for each cultivation pot.
Here, in order to make observation and record creation easy, it is better to write a label for identifying the cultivation pot, for example, to display an identifiable display on the pot, or to make a label stand. Well, it is also effective for making a record to appropriately take a picture during observation.
6). Observation ends when a period required for the growth of the crop, for example, 30 to 35 days in the case of Komatsuna, has passed.
7). After the observation, let them compare how the crops grew in each pot.

In order to further improve the learning effect, it is better to announce the state of growth, the findings and observations from the observation, and it is even better to announce it before there are multiple students or teachers.
The presenter may be a representative, or may be a group of people who have observed the state of crop growth. Furthermore, a group will be created and a discussion will be held by the representative of each group. It can be a person.

Then, create a guidebook that describes how to sow, cultivate and observe and precautions for doing so, and give it to students and teachers to learn at the start of learning. Cultivation and observation can be prevented.
In addition, as shown in FIG. 1, a student who prepares a recording sheet with a table provided with an observation record column 1, a cultivation pot distinction column 2, and a date column 3 used when preparing an observation record, learns at the start of observation. And give it to teachers to support learners to ensure that observations are made.
As the cultivation pot distinction column 2, for example, in the case where the amount of fertilizer is observed in five stages, it is preferable to provide five columns as shown in FIG. 1 so that the amount of fertilizer can be described in each column. . When it is planned to perform observation with no fertilizer, fertilizer 5 g, 10 g, 15 g, and 20 g as in the examples described later, the amount of fertilizer may be described in advance in each column. .
In preparation for cultivation in different environments, which will be described later, two columns may be provided on the right side of the five columns, or five columns may be provided on the right side of the two large columns.
Furthermore, as shown in FIG. 1, in the upper part of the date column 3, there are a column 4 for identifying a group such as grade, group, group, name, etc. and individual items such as a crop name, sowing date, fertilizer name, and cultivation environment. You may provide the column 5 which describes the information common to a cultivation pot, and may provide the notes description column 6 at the time of producing an observation record, and the photograph sticking column 7 for every cultivation pot distinction in the lower part.

When carrying out such a plant cultivation method, advanced learning can be performed by performing the following advanced measurement and observation.
a. Measurement of soil fertilizer concentration (EC) and PH before seeding and measurement of soil fertilizer concentration (EC) and PH when cultivation is completed.
b. At the end of the cultivation, the crops are uprooted and the roots are washed and then the shape of the roots (number, length, weight) is measured.
c. 2.3.4. Prepare an even number of any or all of the cultivation pots, place half on the open-air, and place the other half on a different environment from a simple house or other open-air.
d. Using a transparent pot as a cultivation pot, observe the growing roots during cultivation (the state of the root near the pot can be observed). However, when a transparent cultivation pot is used, it is better to wrap a light-shielding sheet around the cultivation pot because the roots dislike light rays. Remove the sheet only when observing, and wrap it again when observation is complete. As the light shielding sheet, an aluminum foil is preferable from the viewpoint of light shielding power, durability, and availability.
In any case, the learning effect can be further improved if the measurement results and observation results are compared and announced.
In addition, by harvesting the cultivated crop, cooking it, and eating it, the learner can be given joy of harvesting, so cooperation with food education can also be achieved.

After learning the principle of biological growth by the first plant cultivation method, the third plant cultivation method, and then reusing the multiple cultivation pots and soil used for cultivation, cultivating crops for a successful experience An embodiment in doing so is as follows.
(1) Remove soil from a plurality of cultivation pots.
(2) Mix the soil of the removed cultivation pot evenly.
(3) Dry the mixed soil in the shade for 4-5 days.
(4) Mix about 20% of soil improvement material with respect to the amount of dried soil.
Here, as the soil improving material, bark, rice bran, humus or the like is suitable.
(5) Mix an appropriate amount of organic fertilizer and lactic acid eggshell into the soil.
Here, as the organic fertilizer, Bradmin (trade name), an organic fertilizer obtained by aging fish meal or the like, is particularly suitable.
(6) Put soil mixed with soil improvement material, organic fertilizer and lactic acid eggshell in a cultivation pot.
(7) Sowing crop seeds in a cultivation pot.
Here, as a seed of the crop, Komatsuna used in the above plant cultivation method may be used, or other kinds of seeds may be used, but young leaves of about 10 to 30 days after germination can be harvested and eaten. , Komatsuna, Mizuna, Rocket Salad, Red Mustard, Red Oak, and other baby leaf seeds sold under a mix of crops, all year round, anywhere It is particularly suitable because it can be cultivated and the shape and taste of multiple types of vegetables can be enjoyed.
(8) Cultivate crops by placing the cultivation pots seeded with crop seeds in an environment suitable for cultivation.

Next, the embodiment of the plant cultivation kit for education of the invention which concerns on Claims 1-4 is as follows.

1. Multiple cultivation pots of the same shape and size.
In this cultivation pot, it is more preferable to provide a display surface on the top and / or side surface of the pot to facilitate display for enabling identification of cultivation conditions and the like, and such a display surface is provided. If not, a label for display may be added, or a hole for inserting the label together with the label or a surface for facilitating the label may be provided on the cultivation pot. The surface that makes it easy to apply the label is a flat portion that is the same as or slightly larger than the shape of the lower portion of the label, and it is better to provide an adhesive surface with release paper on the flat portion.
It is more preferable that the display surface or label is provided with a column for entering part or all of the crop name, sowing date, fertilizer name, fertilizer amount, growth environment, group name, individual name, etc. The crop name, fertilizer name, fertilizer amount and growth environment may be entered in advance in a cultivation pot or label.
Also, if the label has a jagged bottom, it will be difficult to come out even if it is inserted into the soil, and if a hole for inserting the label is provided in the cultivation pot, the hole will be a size slightly smaller than the thickness or width of the jagged Thus, it is possible to prevent the label from being easily removed once the label is inserted.

2. Crop seed suitable for observation in cultivation pots.
As a seed of the crop, any seed can be used as long as it can be grown in a cultivation pot, but Komatsuna which can be easily cultivated anywhere in the year is suitable. Komatsuna has a strong ability to absorb fertilizers, so that nutrient deficiency is easy to observe, especially in cultivation using soil that does not contain fertilizers.
Other than Komatsuna, lettuce is also suitable. Since lettuce is sensitive to fertilizer concentration, it is easy to observe poor germination and poor growth in cultivation using soil containing an amount of fertilizer that is not suitable for crop growth.

3. Soil that does not contain fertilizer for crop cultivation.
Any soil that does not contain fertilizers can be used, but in order to improve ventilation and water flow in mountain soil or black soil, we mixed bark, rice chaff or humus, etc., about 10% of the soil volume. A thing is preferable when growing a crop in a cultivation pot.

4). Fertilizer suitable for crop growth.
Fertilizers suitable for the growth of crops are fertilizers that are generally commercially available and are not particularly limited as long as they are suitable for the crops, but contain nitrogen, phosphoric acid, and potassium, which are readily effective for fertilizers. Fine grain chemical fertilizer is preferred.
The soil containing no fertilizer content, soil containing fertilizer component in an amount not suitable for the growth of the soil and crop comprising a fertilizer component in an amount suitable for crop growth, keep in advance a bag respectively.
The bag you put these fertilizers and soil, to describe an amount or percentage, as well as the type of fertilizer of fertilizer of fertilizer, it may be described with the type of soil.
In addition, in preparation for the case of performing the re-seed sown and cultivated using the same soil, soil improvement material for the continuous cropping fault tolerance, organic fertilizer, you add the seeds of crops to be cultivated in lactic acid eggshell and the second time. As the soil improvement material, bark, rice husk or humus corresponding to about 20% of the used soil amount is suitable, and Bradmin (trade name) is suitable as the organic fertilizer.

5. A guide describing how to sow the seed and how to cultivate and observe the crop.
The method of sowing seeds is to explain how to mix fertilizer in soil that does not contain fertilizer, how much soil is put in the cultivation pot, how to spread seeds in the cultivation pot, etc. However, it is easier to understand if you explain with pictures.
The method of cultivation and observation of crops is to explain the method and timing of watering, the points to be recorded when observed, etc., and the explanation by text is the most usual method, but if you explain with pictures Easy to understand.
If you attach a record sheet with a table with the observation record field 1, the cultivation pot distinction field 2 and the date field 3 used when creating the observation record as shown in FIG. Support learners to make observations.
The above guidebook may include points to keep in mind when making presentations or group discussions, and if you attach a note paper that lists important items when making presentations or group discussions, the issues will be organized for the learners. It becomes easy.

As an example of an educational plant cultivation kit, 5 cultivation pots (capacity approx. 1 liter), 5 bags of special soil (no fertilizer, approx. 5 liters), 70 g of special fertilizer, 500 seeds of crops (Komatsuna), 5 labels A set of 1 cultivation manual.
And an example of the condition setting of the fertilizer in a cultivation manual is a non-fertilizer, 5g, 10g, 15g, 20g, and an example of the growth result of about 1 month after cultivation in the street was as follows.
For non-fertilizer: germinate, but the leaf color becomes lighter and then growth is delayed.
In the case of 5 g of fertilizer: germination is good and grows smoothly.
In the case of 10 g of fertilizer: good germination and grows smoothly.
In the case of 15 g of fertilizer: germination is poor, the leaf color becomes dark, and the growth shrinks and is delayed.
In the case of 20 g of fertilizer: germination is poor, the leaf color is dark, the growth is shrunk and dies.
Furthermore, in the winter and summer seasons, 6 fertilizer 5g or 10g cultivation pots are prepared, 3 are open-air, and the other 3 are grown in a simple house. Growth was delayed and there were pests in the summer, but in the simple house, it grew stably and smoothly regardless of the season and pests.

In addition, after cultivating crops with different amounts of fertilizer as described above, and after cultivating and observing the crops, the five cultivation pots and soil used for cultivation are reused to achieve a successful experience. As an example of an educational plant cultivation kit for cultivating rice, 5 pots (about 1 liter in capacity), 5 bags of special soil (no fertilizer, about 5 liters), 70 g of dedicated fertilizer, 500 seeds of crops (Komatsuna) ), 5 labels and 1 cultivation manual, bark, rice chaff or humus (capacity about 1 liter) used for the second cultivation, Bradmin (trade name) about 50 g, lactic acid eggs shell about 50 g and baby leaf (product) Name) plus 1000 seeds.
An example of a method for cultivating a baby leaf (trade name) by reusing the five cultivation pots and soil used for cultivation after the first cultivation using this kit is as follows.
(1) Turn over the soil of the five cultivation pots on a sheet or newspaper and remove the stock and roots.
(2) Since the soil of each cultivation pot has a different fertilizer concentration, mix evenly so that the fertilizer concentration is uniform.
(3) Spread thinly in order to supply enough oxygen to the soil, and dry in the shade for 4-5 days.
(4) In order to prevent damage to the roots during cultivation, a soil improvement material (bark, rice bran, humus, etc.) of about 20% of the soil amount is mixed with the soil to improve the air permeability and water permeability of the soil.
(5) To prevent deficiency of nutrients during cultivation, mix 1 tablespoon (50 g) of organic fertilizer Bradmin (trade name) aged with fish meal and the like into the soil.
In addition, in order to prevent calcium deficiency from occurring in the crop, a tablespoon (50 g) of lactic acid eggshell containing calcium is mixed with the soil. Then the crop will be delicious.
(6) Put soil mixed with soil improvement materials, organic fertilizer and lactic acid eggs evenly into a plurality of cultivation pots.
(7) Sowing seeds of baby leaves (trade name) in cultivation pots.
(8) Cultivate crops by placing the cultivation pots seeded with baby leaf (trade name) seeds in an environment suitable for cultivation.
Here, the environment suitable for cultivation may be an open-air if the temperature is relatively high and no pests are generated, otherwise it is in a simple house, a plastic house or a greenhouse that can be used for temperature control and pest control. To do.
The method of sowing and cultivating the seeds of baby leaves (trade name) is the same as the method of sowing and cultivating the seeds of Komatsuna.
And in the cultivation manual, the procedures of (1) to (6) and the method of sowing and cultivation of baby leaf (trade name) are the same as the method of sowing and cultivation of Komatsuna seeds. Is described. The description of the above procedures (1) to (6) is also the most normal method, but it is easier to understand if described with a picture.
