1. Claim 1: a method for using the lower fertilizer produced by the reaction of yeast or yeast component with phosphoric acid and / or potassium component in the factory after the reaction of hydrothermal solution, which is characterized by applying reducing fertilizer to an area of arable land Plant leaf is a deciduous fruit tree. It falls from physiological fruit to fruit harvest for a period of time to restrain the deformation of deciduous fruit tree after harvest. Requirement 2: a method applicable to the plant,A low fertilizer produced by hydrothermal reaction of yeast or mixture of yeast component and phosphoric acid component and / or potassium component, which is characterized by applying reduced fertilizer to the leaf surface of plants, i.e. a deciduous fruit tree, Over a period of time, from the beginning of physical fruit to fruit harvesting, increasing the nutrients stored in deciduous fruit trees. Requirement 7: a preparation for inhibiting post harvest deformation on deciduous fruit trees,This substance is characterized by its production when yeast or a mixture of yeast ingredients and phosphoric acid and / or potassium ingredients are submitted to a hydrothermal reaction. Claim 8: a nutrient enhancer stored on deciduous fruit trees, characterized in that the enhancer is produced when a yeast or yeast component is mixed with phosphoric acid and / or potassium component in a hydrothermal reaction.Reivindicación 1: Un método para aplicar, a una planta, un fertilizante reducido obtenido al someter una mezcla de una levadura o un componente de levadura y un componente de ácido fosfórico y/o un componente de potasio a una reacción hidrotérmica, el método caracterizado porque comprende aplicar el fertilizante reducido a una superficie de hoja de la planta, que es un árbol frutal de hoja caduca, durante un periodo desde el inicio de la caída de fruta fisiológica a la cosecha de la fruta, para inhibir la defoliación después de la cosecha en el árbol frutal de
