Description

The invention relates to the field of agriculture and is intended to create a method for producing a stimulator that accelerates the energy and speed of germination of seeds of grain crops.

A known method of obtaining (N, N'-tetramethylmethylenediamine oxalic) copper sulfate pentahydrate, which can be used as a stimulator of growth and productivity of plants [1].

A known method of obtaining a growth stimulator in the processing of a humic containing component with alkali [2].

A known method of obtaining a plant growth stimulator from resinous-asphaltene substances of low-sulfur oils and naphthenic type bitumen [3].

A known method of obtaining a plant growth stimulator when processing peat with an aqueous solution of ammonia and hydrogen peroxide when heated [4].

A known method of obtaining a plant growth stimulator from an extract of purple coneflower [5].

Known methods allow to obtain plant stimulants, but are more difficult to prepare and involve the use of more expensive drugs.

The invention is aimed at creating a method of obtaining a plant stimulant that accelerates the energy and speed of germination of seeds of grain crops.

The technical problem solved by the invention is to expand the range of methods for producing plant stimulants intended for presowing treatment of seeds of grain crops.

The technical result is the creation of a stimulator that increases the energy of germination and germination of seeds, accelerating the onset of ripening of crops, as well as expanding the arsenal of funds for this purpose.

This is achieved by the production of tris (2,2-dichlorocyclopropylmethyl) phosphate C ₁₂ H ₁₅ Cl ₆ O ₄ P by oxidation with atmospheric oxygen at room temperature of tris (2,2-dichlorocyclopropylmethyl) phosphite.

In a round-bottomed flask equipped with a capillary, dried air was passed through a solution of tris (2,2-dichlorocyclopropylmethyl) phosphite for 1 hour, while an oily tris (2,2-dichlorocyclopropylmethyl) phosphate was formed, which was dissolved in distilled water to obtain 0.01 % aqueous solution of the stimulator.

Example. Barley seeds of the Elf variety and oats of the Adamo variety were soaked in distilled water (control) and in a 0.01% aqueous solution of tris (2,2-dichlorocyclopropylmethyl) phosphate for 2 hours at the rate of 1 liter of solution per 1 kg seed. The determination of the energy of germination and germination of seeds was carried out according to GOST 12038-84 "Seeds of agricultural crops. Germination determination methods. " Accounting for germinated seeds was carried out in two terms (on the third and seventh days) in accordance with GOST (table).

Table The effect of presowing seed treatment on the germination energy and germination of barley seeds, Elf variety, oats, Adamo variety Experience Options Germination energy,% Germination,% Barley grade "Elf" the control 42.5 85,4 experience 48.1 95.9 Oats grade "Adamo" the control 33,4 81.7 experience 37.1 92.2

From the table it follows that when seeds are processed with a 0.01% aqueous solution of tris (2,2-dichlorocyclopropylmethyl) phosphate, the germination energy increases by 13.2% (barley cultivar Elf) and 11.0% (oats cultivar "Adamo"), laboratory germination is increased by 12.3% (barley cultivar "Elf") and 12.8% (oats cultivar "Adamo").

Thus, the use of a stimulant for pre-sowing treatment of cereal seeds containing tris (2,2-dichlorocyclopropylmethyl) phosphate can increase the germination energy and germination of cereal seeds: barley cultivar Elf, oats cultivar Adamo, which accelerates the onset of agricultural maturation cultures.
