Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to the means of stimulation of germination of agricultural crop seeds, and can be used for pre-sowing treatment of seeds. Before sowing the seeds of agricultural crops are soaked for 3-4 hours in 5-6% aqueous solution of juice of creeping crown vetch pressed in a phase of flowering of the plants, and 2-3 ml of ethyl alcohol per 100 ml of the juice is added.

EFFECT: proposed method enables to stimulate the germination processes of seeds and to reveal simultaneously the protective properties with respect to seed and germinated plants.

Description

The invention relates to agriculture, in particular to means of stimulating the germination of seeds of agricultural crops, and can be used for presowing treatment of seeds.

A known method of pre-sowing seed treatment (ed. microbicidal polymer.

However, the drug is used as a seed dressing agent, and it is prepared on the basis of an organic solvent, which complicates the technical solution.

There is also known a method of stimulating the rooting and growth of cuttings, in which as a growth stimulant use a plant of sylphy prickly leaf in 2% concentration (RF patent 2273996 from 04.20.2006, IPC A01N 65/00).

However, in the known method, sylphy juice is used as a growth-promoting environmentally friendly preparation for vegetatively propagated crops.

A known method of presowing treatment of seeds (RF patent No. 2032301 dated 04/10/1995, A01N 65/00), in which the seeds are soaked in alfalfa extract for 6-24 hours at a concentration of 0.01-1% before sowing.

The disadvantage of this method is that alfalfa extract is obtained by heat treatment (t 120-130 ° C) in an autoclave, followed by evaporation.

The heat treatment process complicates the method, part of the alfalfa nutrients is lost.

The technical result is a simplification of the method, expanding the range of herbal remedies to stimulate the germination of seeds.

The technical solution of the claimed object is that the seeds are soaked before sowing for 3-4 hours in a 5-6% aqueous solution of variegated apricot juice, squeezed from plants selected in the flowering phase, while 2-3 ml are added to 100 ml of juice ethyl alcohol as a preservative.

The most important element of the juice is the coronillin glycoside, which is similar in composition and effect to cardiac glycosides.

When exposed to seeds, glycosides have a stimulating effect and at the same time negatively affect the diseases of seeds and sprouted plants.

In addition, motley motley in the flowering phase is characterized by a high protein content (more than 20%), also contains molybdenum, cobalt, manganese, nitrogen, phosphorus, potassium and other elements that are stimulators of seed growth.

A small amount of ethyl alcohol (2-3 ml per 100 ml of juice) is added to freshly squeezed plant juice in order to preserve all the valuable substances contained in the gum juice.

In this form, the juice can be stored for a long time and can be used in the winter to determine the germination of various seeds. Presowing seed soaking in a 5-6% aqueous solution of knitting juice for 3-4 hours increases germination, seed germination energy and reduces the incidence of sprouts. The justification of the selected parameters (5-6% solution) is explained by the content of macro- and microelements in the culture of the binder, as well as experimentally confirmed.

The method is as follows. Well-leafy plants are selected from variegated (Coronillf varial) plants during the flowering phase when the maximum amount of nutrients is accumulated.

As a result of a preliminary laboratory experiment with the soaking of winter wheat seeds in an aqueous solution of variegated sap juice with concentrations of 2-3%, 5-6%, 9-10% for 1-2, 3-4, 6-8 hours, optimal germination was noted when soaking the seeds in a 5-6% juice solution for 3-4 hours. Soaking for 6 hours or more, as well as a solution concentration of 9-10%, did not significantly affect the germination of wheat seeds.

In a field experiment, the seeds of winter wheat were soaked in a 5% solution of the juice of a viscomer with alcohol for 4 hours and the seeds of mogar in a 6% solution for 3 hours.

Germination energy, seed germination, disease susceptibility of young shoots were determined (table).

Claims (1)

A method for pre-sowing seed treatment, including soaking the seeds in a solution of grass juice, characterized in that the seeds are soaked in a 5-6% aqueous solution of yogurt juice for 3-4 hours, the juice being squeezed out of the plants into the flowering phase and added to the squeezed juice 2- 3 ml of ethyl alcohol per 100 ml of juice.
