Description

The invention relates to the field of agriculture and can be used to improve the sowing qualities of seeds of vegetable 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 bisethane-1,2-dicarbonatethylenediammonium 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) bismalondiamide chloride of the formula [CuCl ₂ (C ₃ H ₆ N ₂ O ₂ ) ₂ ] as 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 stimulator of grain growth [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 aimed at creating a method that stimulates the germination of seeds of vegetable crops.

The technical problem solved by the invention is to expand the range of stimulators of germination of seeds, increase the energy of germination and germination of seeds of vegetable crops.

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

This is achieved by using 2-phenylenethenylphosphonic acid C ₈ H ₉ PO _{3 of} formula (I) as a stimulant that increases the germination energy and germination of seeds of vegetable crops.

Example. Seeds of cabbage of the June Early, Kharkov Winter and Kolobok varieties, Moravian Miracle tomato and Malysh cucumber were soaked in distilled water (control) and in 0.1% -, 0.05% -, 0.01% -, 0.005% -, 0.001% aqueous solutions of 2-phenylethenylphosphonic acid for 2 hours at the rate of 1 liter of solution per 1 kg of seeds. The determination of germination energy and germination was carried out according to GOST 12038-84 "Seeds of agricultural crops. Germination determination methods. " The accounting of germinated seeds was carried out in two terms (on the third and seventh days) in accordance with GOST (table).

From the data of the table it follows that when processing seeds of vegetable crops with 0.01-0.05% aqueous solutions of 2-phenylenethenylphosphonic acid, the germination energy and laboratory germination of vegetable crops significantly increase.

Thus, the use of the proposed stimulant for pre-sowing treatment of seeds of agricultural crops containing 2-phenylenethylphosphonic acid, can significantly increase the germination energy and germination of seeds of cabbage varieties "Early June", "Kharkov winter" and "Kolobok", tomato varieties "Moravian miracle" and cucumber varieties "Kid", which accelerates the start of ripening of vegetable crops.
