2. Description of the Related Art In general, a crop is a plant cultivated on arable land for use in clothing, food and shelter.
Stems, leaves, flowers, roots, etc. are used. For example,
"Crops using leaves such as cabbage and tea", "Crops using stems such as asparagus and udo", "Sweet potatoes,
Crops that use roots and rhizomes, such as potatoes, "
There are "crops using flowers such as hops and saffron", "crops using seeds such as wheat, corn and soybean", and "crops using fruits such as cucumber, grapes and bananas". It is known that substances necessary for growing various crops are inorganic nutrients and sugar. Inorganic nutrients are taken in from the soil as nutrients and sugars are produced as photosynthesis. Although more than 30 species are known as basic elements involved in the growth, that is, elements contained in the body of a plant, 16 of them are essential elements indispensable for growth, and carbon, oxygen, Hydrogen, nitrogen,
It is a major element of phosphorus, sulfur, potassium, calcium and magnesium and trace elements of iron, copper, manganese, zinc, molybdenum, boron and chlorine. Although carbon, hydrogen, and oxygen are present in large amounts in crops, they are not usually required to be provided because of their abundant natural supply as air (carbon dioxide) and water. Nitrogen, phosphorus, and potassium are well known in particular as the three elements of fertilizers because of their relatively low abundance in soil and high response of plants to external supplementation. Sulfur, calcium, magnesium, iron,
Copper, manganese, zinc, molybdenum, boron, and chlorine are not all abundant in the soil, but can be deficient due to the amount of forms readily available to the crop (available) and imbalance with other elements. is there. Elements other than carbon, oxygen and hydrogen are
Since all of these elements are generally absorbed as an aqueous solution from the soil, if the soil is deficient in these elements, the soil cannot maintain its productivity unless it is artificially supplied. Therefore, a large number of fertilizer products classified as special fertilizers from ordinary fertilizers have been used in the Fertilizer Control Law. On the other hand, carbon, oxygen, and hydrogen are converted into carbohydrates (sugars) by photosynthesis to form a plant skeleton, and carbohydrates are involved in the production of proteins and lipids. Carbohydrates are also important as an energy source for growth. This photosynthesis is known as a carbon dioxide fixing mechanism. Carbon dioxide will vary passed a series of reactions in carbohydrates (sugars) other compounds, but the first case a (C ₃ type plants) the first product carbon perform photosynthesis only Calvin acid cycle in three trioses product are divided into such CAM plant to be fixed as another case with dicarboxylic acids circuit (C ₄ type plants) and once malic acid Calvin acid cycle carbon is four dicarboxylic acids. The main sugars in this photosynthesis and glycolysis system are sucrose, glucose, fructose and the like. So far, it is not a legal fertilizer in order to promote the photosynthetic action of leaves, but it dissolves sucrose (sugar), glucose (glucose), fructose (fructose), etc. under the name of a plant activator, etc. Giving has been done. For example, P70 of "Flower gardening dictionary" Asakura Shoten (issued October 25, 1986)
Reference numeral 2 shows a cut flower preservative (life-promoting agent) containing a drug, the main component of which is sucrose (sucrose) or glucose. Since organic acids are involved in photosynthesis and glycolysis, rice vinegar and brown rice vinegar containing organic acids have been used empirically.

In view of such circumstances, the present inventors have conducted various studies on the effects of vinegar and saccharides containing vinegar on crop growth and the like, and as a result, have found that sucrose, glucose, The mechanism of action is not clear than fructose and the like, but surprisingly, it has been found that a fermented product containing a branched oligosaccharide-containing saccharide as a component has excellent effects such as crop growth, and the present invention has been completed. I came to.
