Description

The invention relates to the field of agriculture and is intended to increase the energy of germination, seed germination, accelerate the onset of ripening and yield of crops.

A known method of stimulating plant growth, including seed treatment and spraying of plants during the growing season with aqueous solutions of saturated dicarboxylic acids: succinic or malic, malonic and oxalic acids [1].

It is known to use ethylene diammonium bisethane-1,2-dicarbonate of the formula 2C ₂ H ₄ (COOH) ₂ · C ₂ H ₄ (NH ₂ ) ₂ as a stimulator of grain growth [2].

It is known to use copper (II) bismalonamide chloride of the formula [CuCl ₂ (C ₃ H ₆ N ₂ O ₂ ) ₂ ] as a growth promoter of a grain growth stimulator [3].

It is known to use tris (2,2-dichlorocyclopropylmethyl) borate C ₁₂ H ₁₅ Cl ₆ O ₃ B as a growth promoter of a grain growth stimulator [4].

Known drugs can increase the energy and speed of seed germination, but are more difficult to prepare and involve the use of more expensive drugs.

The invention is directed to the creation of a stimulant accelerating the energy and speed of seed germination, accelerating the onset of ripening and yield of crops.

The technical problem solved by the invention is the expansion of the range of stimulants for presowing treatment of seeds of grain crops.

The technical result is to increase the energy of germination and germination of seeds, accelerate the onset of ripening and yield of crops, as well as expanding the arsenal of funds for this purpose.

в качестве средства, повышающего энергию прорастания, всхожесть семян и урожайность зерновых культур.This is achieved by the use of monoethanolammonium oxalate of the formula

as a means of increasing germination energy, seed germination and grain yield.

The proposed stimulant is a white crystals, odorless, well soluble in water. The structure of monoethanolammonium oxalate was confirmed by the data of IR spectroscopy and X-ray phase analysis, and the composition by elemental analysis.

Example 1. Wheat seeds of the grade Moskovskaya-35, barley of the Elf variety and oats of the Adamo variety were soaked in distilled water (control) and in 0.002% -, 0.001% -, 0.0005% - 0.0001% - in aqueous solutions of monoethanolammonium oxalate for 2 hours at the rate of 1 liter of solution per 1 kg of seeds (Table 1).
