Description

  The present invention relates to a method for increasing the yield of fruits and vegetables such as tomatoes, cucumbers, strawberries, peppers and eggplants.

  Promoting the growth of crops and increasing yields by increasing the yield per unit area are important issues in agricultural production. Normally, nutrient elements such as nitrogen, phosphorus and potassium, which are indispensable for plant growth, and trace metal elements, are mixed with the original fertilizer and supplementary fertilizer and supplied to plants. Generally, however, the concentration of nutrient elements in fertilizers However, there is a limit to the improvement of crop growth and yield, and the use of a large amount of fertilizer increases the amount of nutrient elements in the soil, resulting in a poor balance of absorption, causing plant growth stagnation, etc. However, problems such as failure to achieve the target increase in sales and quality such as sugar content (Brix. Value) and freshness (greenness) do not increase. Under such circumstances, various plant growth regulators are used in combination.

As plant growth regulators, for example, plant growth regulators represented by gibberellin, auxin, and the like are used for regulation of germination, rooting, elongation, flowering, fruit growth, and morphogenesis reaction. In addition, there is a technique for foliar spraying or fertilizing a liquid fertilizer containing a foliar spray agent using oligosaccharide (Patent Document 1), sugar, minerals, amino acids, seaweed extract or microbial fermentation extract. Are known. Patent Document 2 discloses that an alcohol having 30 carbon atoms is used as a plant growth promoter. Patent Document 3 discloses a plant vitality agent composed of a monohydric alcohol having 12 to 24 carbon atoms. Further, Patent Document 4 discloses a crop yield increasing agent comprising a specific compound such as a monohydric alcohol having 12 to 24 carbon atoms.
