2. Description of the Related Art Beans of legumes are rich in protein and fat and are considered to be the best foods after meat in terms of nutrition. Soy bean sprouts that have germinated soybeans have excellent nutrition. As a source, it is a very popular food. When treated with a plant growth promoting pesticide, soybean sprouts can suppress elongation by about 35% and grow the hypocotyl thickness by 40%. In addition, antiseptic agents, antioxidants and the like are used in order to improve preservability, since spoilage by microorganisms and deterioration in quality due to oxidation and enzymes are typical causes for shortening the distribution period of agricultural products. It is necessary. For this reason, soybean sprouts often use an antibacterial pesticide, a growth promoting pesticide, and the like in the cultivation process.

[0003] Recently, in a survey by the Korea Consumer Protection Agency,
Carcinogenic or teratogenic pesticide components were detected in some unpackaged soybean sprouts, and thiophanate methyl (thiophanate methyl) was detected.
An analysis result showed that a pesticide component called atemethyl) was detected at 0.2 to 7.7 ppm. This thiophanate methyl is used for cultivation of seed rice, onions, beans, sesame, etc.
A compound used to disinfect seeds before sowing, but when used in soybean sprouts, it is decomposed into cabendazim, a teratogenic or carcinogenic toxic substance, by metabolism of soybean sprouts itself. The use of this compound in soy bean sprouts is banned in Korea.

[0004] For these reasons, in recent years, consumers' interest in health has been increasing, and food safety and hygiene have been strongly demanded. Along with this, the demand for producing agricultural products without pesticides or low pesticides is increasing year by year.

[0005] Therefore, a patent application for a low-toxicity seed germination and plant growth promoter has been filed. For example, Korean Patent No. 9

Outside this temperature range, the formation of an anionic mineral reaction may be destabilized.

It should be noted that the use of both sodium silicate and sodium silicon hydroxide, or the use of either one of them, does not interfere with achieving the object of the present invention. However, when both of these components are used and when one of them is selected and used, it is preferable to use the same amount. Similarly, the use of both sodium carbonate and sodium bicarbonate, or the selection and use of either one, does not interfere with the purpose of the present invention. However, when both of these components are used and when one of them is selected and used, it is preferable to use the same amount.

As can be seen from Table 2, soy bean sprouts grew fastest when cultivated with composition B added.
In addition, the thickness and weight of the soybean sprouts to which the composition B was added were superior to the control, but the results were lower than those in the case where the above-mentioned pesticides were added. This means
This is because indolbi, a pesticide, contributes an effective property for promoting plant growth. However, even with the safe composition B, which does not use toxic substances, good results can be obtained which are not inferior to those when the above-mentioned pesticides are used, which demonstrates the usefulness of the present invention. It is considered something. In addition, from the result of Example 3, when applied to germination and plant growth, the effective addition concentration of the composition of the present invention is 0.2
