[Field of Industrial Application] The present invention is directed to hydroponic cultivation, which uses a nutrient solution to promote plant growth, increase plant yield, and improve the productivity of plant cultivation by increasing the number of plantings of plants. Concerning plant cultivation methods. The method of cultivating plants using a nutrient solution of the present invention can be used for artificial cultivation of plants called hydroponic cultivation such as hydroponic cultivation, gravel cultivation, or rock wool cultivation, and the nutrient solution can be sprayed onto the roots of cultivated plants. It can be used for so-called fog cultivation using fog boxes, and it can also be used for tissue culture of plant cells. [Technical Background and Description of Prior Art] Plant growth is said to require trace elements such as magnesium, calcium, iron, manganese, and boron in addition to the three elements nitrogen, phosphoric acid, and potassium. However, in addition to these elements, it is widely known that a number of compounds called plant hormones can be applied to plants to promote their growth. Until now, betaine and choline have been included in organic fertilizers, and it is known that betaine and choline have a positive effect on the growth of barley and buckwheat. [Kiyohisa Yoshimura: Journal of the Japanese Society of Agricultural Chemistry, Vol. 2, No. 26, p. 779 (1926), Kiyohisa Yoshimura: Kagoshima Advanced Agriculture and Forestry Report (1922)] It is also known that chloride coins promote rooting and increase yields of sweet potatoes. It is being [Ministry of Agriculture and Forestry Agricultural Technology Training Institute, Agriculture, Forestry and Fisheries Technology Council Secretariat: Research on crop growth adjustment using chemical substances (1971)] After World War II, with the occupation of the US military, hydroponic cultivation of vegetable crops was put into practical use. Hydroponic cultivation of plants has become widely practiced, and research on tissue culture of plant cells is progressing, and research on cultivation of plants using nutrient solutions containing plant nutrients and tissue culture of plant cells is progressing. On the other hand, betaine is contained in the juice of sugar radish (beet), and there are glycine betaine and γ-butyrobetaine.Although most betaines are contained in plant or animal tissues, they are generally not found in biological sources. The significance is said to be unknown. ("Encyclopedia of Chemistry" published by Kyoritsu Publishing Co., Ltd. Vol. 8, p. 319 "Betaine") The present inventors have been engaged in the production of fertilizers and research on crop nutrition for many years, and in that research, we found that betaine Based on these findings, we have discovered that it is possible to promote the development of root hairs, increase the amount of roots, promote plant growth, accelerate the harvest period of crops, and increase the yield of crops. We have arrived at the present invention. [Object of the Invention and Summary of the Invention] The present invention provides a new method for cultivating plants using a nutrient solution, and more particularly, a method for cultivating plants using a nutrient solution that promotes the growth of plants and increases their yield. It consists in proposing laws. The present invention is a method for cultivating plants characterized by supplying a nutrient solution containing 1 to 500 ppm of betaine in the cultivation of plants in which a nutrient solution is supplied to plants supported on a substrate. In the plant cultivation method of the present invention, a sand cultivation method uses a sand layer as the substrate that supports the plants, a gravel cultivation method uses a gravel layer as the substrate that supports the plants, and a rock wool method uses rock wool as the substrate that supports the plants. , hydroponic method in which the substrate supporting the plants is made of foamed plastic, or mist cultivation in which the substrate supporting the plants is made by drilling holes in the top of the box and nutrient solution is sprayed onto the roots inside the box. (Fog Box) method. The plant cultivation method of the present invention can be used for tissue culture of plant cells, and the nutrient solution of the present invention is used as a culture solution in tissue culture of plant cells. [Specific Description of the Invention] The substrate that supports the plant in the plant cultivation method of the present invention may be any substrate as long as it supports the growing plant so as not to cause any hindrance to the growth of the plant. You can use this even if The substrate that supports the plants in the plant cultivation method of the present invention corresponds to the cultivated soil in the field in agricultural production using fields, and is a sand layer in the sand cultivation method and a gravel layer in the gravel cultivation method. In the rock wool method, it is rock wool, in the hydroponic method using foamed plastics, it is the foamed plastic pine, and in the tissue culture of plant cells, it is the culture medium in the culture tank. Furthermore, in fog cultivation using a fog box, the top of the fog box has a hole in it to support the plant body. In these plant cultivation methods, the nutrient solution is absorbed and utilized by the plants (mainly their roots) to replenish the nutrient solution.
In the present invention, the betaine concentration in the supplemented nutrient solution is adjusted to 1 to 500 ppm. Adjustment of the concentration of betaine in the nutrient solution promotes the development of root hairs in plants, increases root mass, promotes plant growth, and thereby increases plant yield. Any nutrient solution that can be used in the sand cultivation method, gravel cultivation method, rock wool method, hydroponic method, fog cultivation method, and tissue culture method described above can be used as the nutrient solution. . The plant cultivation method of the present invention can be used to cultivate any plant as long as it is cultivated by the above-mentioned cultivation method, including tomatoes, cucumbers, melons, and green peppers. It can be used to grow , eggplants, strawberries, green onions, honeysuckle, watercress, lettuce, roses, carnations, etc. As betaine, basic glycine betaine and γ-butyrobetaine can be used. The present invention will be explained in more detail below using test examples that can be substituted for examples, but the present invention is not limited to these examples.
