Description

  The present invention relates to a plant vital agent composition. Here, hereinafter, the “plant” represents one that can be recognized from the wording of the plant itself, vegetable, fruit, fruit tree, grain, seed, bulb, flower, herb (herb), taxonomic plant, etc. .

  Various nutritional elements are necessary for plants to grow, but it is known that if some of these elements are deficient, plant growth will be hindered. For example, as the three major elements of fertilizer, nitrogen is a component element of protein. Phosphorus plays an important role not only in the constituent elements of nucleic acids and phospholipids, but also in energy metabolism and synthesis and decomposition reactions of substances. There are physiological effects of substance metabolism and mass transfer. The lack of these major components generally leads to poor plant growth. Calcium is an important component that constitutes plants and cells, and also plays an important role in maintaining the balance of the metabolic system. In addition, various nutrients are necessary for plants such as Mg, Fe, S, B, Mn, Cu, Zn, Mo, Cl, Si, and Na.

  These nutrients such as nitrogen, phosphorus, and potassium are fertilized in the form of original fertilizer and additional fertilizer, or liquid fertilizer is diluted and applied by soil irrigation or foliar application. These fertilizers are indispensable for plant growth, but even if given at a certain concentration or higher, they cannot contribute to improvement of plant growth and yield.

  However, promoting the growth of crops and increasing the yield by increasing the yield per unit area is an important issue in agricultural production, and various plant growth regulators necessary for this purpose have been developed and used. Plant growth regulators typified by gibberellins and auxins are used to control germination, rooting, elongation, flowering, fruit growth, and morphogenic reactions. And complex and has limited applications.

In order to solve such problems, foliar spray using oligosaccharide (Patent Document 1), foliar spray of liquid fertilizer containing sugar, mineral, amino acid, seaweed extract or microbial fermentation extract or The solution fertilization technique is known, but it cannot be said that the effect is practically sufficient. In addition, as disclosed in Patent Documents 2 to 11, vitality imparting to plants using various substances, yield increase or quality improvement for agricultural crops have been proposed.
JP-A-9-322647 JP 2000-198703 A JP 2001-288010 A JP 2001-316204 A JP 2001-316205 A JP 2001-316208 A JP 2001-316207 A JP 2002-265305 A JP 2002-265306 A JP 2006-182684 A JP 2006-213612 A

  As a result of applying a large amount of fertilizer to the soil for the purpose of increasing crop yields, various elements in the soil become excessive, the balance of absorption becomes worse, plant growth stagnation, etc. There are problems that cannot be achieved or quality such as sugar content (Brix. Value) does not increase. In addition, because the roots have limited nutrient absorption, there is an attempt to spray an aqueous solution or suspension of the required fertilizer element directly and absorb it from the leaf surface or fruit. However, there is a problem in terms of absorption efficiency, and spraying an excessive amount of fertilizer component conversely stresses plants and causes phytotoxicity.

  Under such circumstances, there is a demand for a plant vitality agent that does not cause phytotoxicity or the like on plants and has an excellent versatility for enhancing plant growth.

  The present invention provides at least one antioxidant selected from the group consisting of flavone, quercetin, rutin, chlorophyll, caffeine, catechin, polyphenol, sesamin, sesamol, astaxanthin, curcumin and carotene (hereinafter referred to as component (a)).
