Obtained by removing sodium chloride and toxic components. The obtained MCM is chelated by plankton in seawater.

As seawater that can be used for manufacturing MCM, for example, seawater pumped from clean seawater at a depth of about 80 to 120 m can be used. Table 1 shows the main elements contained in 18 liters of clean seawater drawn about 100 m below the sea level in a typical Kuroshio area (off Oarai) and their proportions. In addition, in addition to the elements listed in Table 1, seawater contains elements such as manganese (Mn) and copper (Cu).

Preferably, approximately the same volume of potassium acetate is added and reacted, and then charged into a seawater concentrate to make the whole solid. In order to make the whole into a solid substance, a substance in which approximately the same volume of potassium acetate is added to calcium phosphate is divided into a plurality of times (usually 8 to 10 times) and then added to the seawater concentrate. For example, potassium acetate is prepared by adding 10% by volume of potassium nitrate to acetic acid. Acetic acid having a content of 98 to 99.9% is preferably used. After adding 40 to 50 L, preferably 45 L, of raw seawater to about 30 L of this solid material to form a fluid containing solids, this is placed in a settling tank at room temperature for 100 hours or more, preferably 150 to 350 hours, and sodium chloride and specific gravity. Large heavy metals (such as mercury) are precipitated. When this is filtered, a transparent aqueous solution from which precipitates and impurities have been removed can be obtained. Filtration can be performed using a filter paper or a resin filter. This aqueous solution is concentrated by heating to 1/3 to 1/5, preferably 1/4, by volume, and then cooled to room temperature to obtain an MCM aqueous solution in a state close to saturation.

Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.

Preparation of MCM solution 200 L of clean raw seawater about 100 m below the sea level in the Kuroshio Sea area (off Hitachinaka city) was collected and concentrated by heating to obtain 100 L of seawater concentrate. To this seawater concentrate, 0.2% magnesium chloride and 0.001% activated carbon were added in a volume ratio and heated to 100 ° C. Separately, calcium phosphate with a volume ratio of 20% with respect to the seawater concentrate is calcined to about 500 ° C., and potassium acetate having the same volume as calcium phosphate (prepared by adding potassium nitrate with a volume ratio of 10% to acetic acid) is added thereto. After changing to calcium, it was put into the seawater concentrate until the whole became solid. This operation was repeated 8 times until the whole became solid. After adding 45 L of raw seawater to about 30 L of this solid to obtain a fluid containing solids, this was placed in a sedimentation tank at room temperature for 120 hours to precipitate heavy metals such as sodium chloride and mercury having a large specific gravity. This was filtered with a filter paper to obtain a clear aqueous solution from which precipitates and impurities were removed. This aqueous solution was concentrated by heating to ¼ by volume and cooled to room temperature to obtain an MCM aqueous solution. This aqueous MCM solution was close to saturation.

Field test The MCM solution was used for the field test of rice (Hinohikari). Specifically, the field was divided into a field (test group) to which MCM was applied and a (normal) field (control group) to which MCM was not applied, and a field test was performed with the cultivation history shown in Table 2 below. In the test group, the MCM diluted solution diluted with water at a predetermined dilution rate shown in Table 2 was sprayed twice on the seedlings and three times on the growth process. In the plow cutting, 50 strains were cut, dried by sun drying, processed using a simple threshing machine and a simple hulling machine, and evaluated.

Evaluation results are shown in Table 3.

The evaluation results are explained below. Together with the evaluation results (Table 3) of the 2017 field test, the evaluation results of the same field test conducted in 2016 are also shown.

[Yield evaluation]
As shown in Table 3, in the test group, the number of pods per pod, the weight of rice bran, and the weight of brown rice all increased significantly compared to the control group, and the yield was increased by using MCM. It is thought that the yield increased due to the promotion of chlorophyll formation and photosynthesis by potassium, iron, manganese, magnesium, zinc, etc. contained in MCM, and the promotion of sugar movement in the plant by calcium and magnesium. FIG. 1A shows an enlarged photograph of a rice ear portion in the test group, and FIG. 1B shows an enlarged photograph of a rice ear portion in the control group. 1A and 1B also show that the number of pods per spike increased in the test group compared to the control group. 2A shows an enlarged photograph of the rice root portion in the test group, and FIG. 2B shows an enlarged photograph of the rice root portion in the control group. 2A and 2B, it can be seen that in the test group, the amount of rooting was larger than that of the control group, the length of the root was long, and lodging resistance was improved.

Table 4 shows the evaluation results for seedlings in the 2016 field test.

In Table 4, the solidity of the seedlings is obtained by dividing the dry matter weight by the plant height. When the solidity of the seedlings is high, the amount of rooting increases during the growth process, the length of the roots increases, and lodging resistance Is expected to improve. The dry weight ratio is obtained by dividing the dry weight by the living body weight. A seedling with a low dry weight ratio is a soft seedling, and a seedling with a high dry weight ratio is a healthy seedling. Healthy seedlings are expected to increase the number of tillers and the number of ears in the course of growth and finally increase the yield of soft seedlings. From Table 4, it was predicted that in the test group, the degree of solidity of the seedlings was higher than that of the control group, the amount of rooting after growth was large, and the length of the root was increased. In the test plot, it was predicted that the dry matter weight ratio was higher than that in the control plot, the seedlings were healthy, and the final yield increased. Calcium, potassium, silicon, iron, etc. contained in MCM strengthen the plant cell tissue and make the roots and foliage strong, improving lodging resistance. In addition, potassium, iron, manganese, magnesium, contained in MCM, The promotion of chlorophyll production and photosynthesis by zinc, etc., and the promotion of protein synthesis by the synergistic action between magnesium, phosphoric acid, and nitrogen are thought to have influenced the numerical improvement.

[Weight reduction rate during hulling]
Table 5 shows the weight reduction rate during rice hulling in the test plot and the control plot. According to Table 5, the weight loss rate at the time of rice smashing was smaller in the test group than in the control group, the ratio of brown rice in the rice bran was high, and the ratio of rice husk was low.

[Particle size ratio]
Table 6 shows the measurement results of the grain size of white rice obtained by polishing rice in the test and control plots. From Table 6, it was shown that the ratio of rice having a large particle diameter of 2.0 mm or more in the test group was significantly high and the loss rice was small in comparison with the control group. It is considered that the particle size was improved by calcium, magnesium, etc. contained in MCM promoting the movement of sugar (starch) generated by photosynthesis to the ear.

[sensory test]
Cooked white rice obtained by milling rice in the test and control plots, and using this as a test sample, a sensory test was conducted by 30 subjects. As a result, 22 people evaluated that the rice in the test area was delicious, which was significantly more than the 8 people who evaluated the rice in the control area as delicious.

[Disease resistance evaluation]
In the field test, Mon blight disease occurred in the control plot, but not in the test plot. This is thought to be because calcium, potassium, silicon, iron, and the like contained in MCM strengthened the cellular tissue of the plant and made the roots and foliage more durable, thereby improving disease resistance.

[Eating quality evaluation]
The amylose, protein, moisture, fatty acid content, and nitrogen content of brown rice and white rice obtained from the rice in the test group and the control group were analyzed, but there was no significant difference between the test group and the control group.
