RU-2861284-C1 - HYDROGEN-SILICON PLANT DEVELOPMENT BIOSTIMULANT AND METHOD FOR DELIVERING THE SAME TO PLANTS

Abstract

FIELD: agriculture. SUBSTANCE: hydrogen-silicon plant development biostimulant is an aqueous solution containing ground silicon Si, water H 2 O, hydrogen ions, molecular hydrogen H 2 dissolved in water, and silicon dioxide SiO 2 . The silicon is pre-ground to fine and ultrafine particles and mixed with polyethylene glycol to a suspension state with a silicon content of at least 37%, obtained by wet grinding in polyethylene glycol and subsequent settling with filtration by means of a high-pressure pump. In the preparation of the aqueous solution, the suspension is mixed with pure water having a temperature of not more than 25°C and a neutral or slightly acidic pH, in the proportion: 1 part of suspension to not less than 1000 parts of water. Mixing occurs by gradually pouring the suspension into the water, followed by the formation of molecular hydrogen H 2 and orthosilicic acid H 4 SiO 4 . A method for delivering the hydrogen-silicon biostimulant to plants is also provided. EFFECT: increasing the digestibility of silicon-containing fertilisers with an antioxidant effect, stimulating the protective properties of plants. 2 cl, 2 dwg, 2 tbl

Description

The group of inventions relates to agriculture, in particular to compositions containing hydrogen-silicon biostimulants for plant development, and methods for delivering it to plants. Plant growth biostimulants are known from the prior art—these are preparations that enhance natural physiological processes in plants. They don't replace fertilizers, but they enhance their absorption, stimulate root growth, accelerate seed germination, and enhance resistance to stress (drought, frost, disease). Unlike traditional fertilizers, biostimulants don't directly supply plants with nutrients, but act as catalysts, accelerating metabolic processes and increasing resistance to external factors. Hydrogen H2 is one such biostimulant. Its beneficial effects include: Antioxidant effect: H2 helps regulate ROS levels, preventing them from causing serious damage to cells. It quenches excess oxidative stress. Signaling function: H2 acts as an important signaling molecule. It "turns on" the expression of genes responsible for the synthesis of protective compounds (phytoalexins), antioxidant enzymes (e.g., catalase, peroxidase), and heat shock proteins. Interaction with other signals: H2 closely interacts with other plant signaling molecules, such as nitric oxide (NO), calcium (Ca2 + ), and hormones (e.g., abscisic acid, jasmonic acid), enhancing the overall defense response. However, storing and applying hydrogen gas in the field is expensive and dangerous. Therefore, the use of hydrogen as a biostimulant for plant development is greatly hampered by its properties. A known method for producing liquid silicon fertilizers involves pre-crushing and dispersing silicon after mixing the coarsely dispersed form with polyethylene glycol and other mineral components, as well as crushing during mixing with polyethylene glycol to obtain finely dispersed silicon (see Russian Patent for Invention No. 2658376, Class C05G 1/00, filed in 2018). This technical solution involves mixing silicon with polyethylene glycol and wet milling it, which improves the quality and storage efficiency of the fertilizer. However, in this known method, uncontrolled chemical reactions can occur during the production of silicon fertilizers, including silicon oxidation, leading to deterioration in the quality of the fertilizer. Insufficient dispersion of the resulting mixture leads to sedimentation at the bottom of the container, caking, and subsequent clogging of nozzles during application. The method involves applying fertilizer after pre-mixing it with water at a fertilizer-to-water ratio of 1:500-1:2000 by weight, followed by spraying the solution onto plant seeds or shoots until completely wet. Thus, the invention aims to improve the efficiency of silicon-containing fertilizers. However, the fertilizer preparation and application methods described in the patent do not yield significant benefits for plant development. A known method for producing liquid silicon fertilizers involves crushing silicon, mixing it with polyethylene glycol, and wet milling. After wet milling, the resulting mixture is allowed to settle for at least 24 hours, followed by obtaining a homogeneous suspended suspension and filtering it using a high-pressure pump (see Russian Patent for Invention No. 2815928, Class C05G 5/20, filed in 2024). This technical solution is aimed at improving the quality of silicon fertilizer and crop yields, as well as its homogeneity, while eliminating sediment at the bottom of containers and clogging of spraying equipment. The silicon fertilizer obtained in this manner consists of finely dispersed and ultrafine particles, which, by penetrating plant cells through the leaves, have a beneficial effect on plant development during the growing season. However, the positive impact of this fertilizer on plant development varies greatly depending on various factors that were not taken into account when developing this technical solution. The closest patent to the claimed technical solution is a method for producing a composition containing fine silicon particles capable of generating hydrogen, which comprises producing finely dispersed silicon particles by grinding the silicon particles in an ethanol solution, and treating the finely dispersed silicon particles or their aggregates with a hydrogen peroxide solution upon contact with the hydrogen peroxide solution, followed by applying this composition to plant leaves (see EP 3505491 A1, class A61K 33/00, published in 2019). This patent describes how a plant absorbs hydrogen released by fine silicon particles or an aggregate when the fine silicon particles or aggregate are placed in a specific environment with moisture (aqueous liquid), fertilizer, or something similar, such as hydrogen (e.g., hydrogen dissolved in water). Hydrogen can enter the plant through the leaves, stems, bark, and/or roots. According to the patent's authors, by properly eliminating or removing, as well as reducing the content of residual active ox
