Abstract

FIELD: agriculture.

SUBSTANCE: method of presowing seed treatment is that before seed treatment with the stimulating solution the seeds are moistened with water or a surfactant. The wet seeds are exposed to mechanical action to increase the number of defects in the seed coat and for penetration of the growth-stimulating solution inside the seed to the corcule. The seeds are then dried.

EFFECT: invention enables to accelerate significantly the growth processes in seeds.

Description

The invention relates to agriculture, namely to the treatment of seeds with plant growth stimulants.

A known method of treating seeds with solutions of the drug "Albit" [1], which is a solution of macro- and micronutrients, coniferous extract, chlorophyll-carotene paste, Bacillus megaterium bacterial hydrolyzate containing poly-β-hydroxybutyric acid biopolymer and Pseudomonas aureofaciens BKM bacterial hydrolyzate 1973D.

The main disadvantage of this method is the low efficiency of the stimulating effect in seed treatment.

The aim of the invention is to increase the stimulating effect of pre-sowing seed treatment, in particular an increase in their growth power [2].

The technical essence of the invention lies in the fact that wet seeds are subjected to mechanical stress, which increases the number of defects in the seed coat and the ingress of a solution with a growth promoter inside the seed to the germ.

The problem is solved in that in the method of pre-sowing seed treatment, including treating the seeds with a solution including a drug stimulating the development of plants, the seeds are moistened, after which they are mechanically impacted, and also that the seeds are wetted with water or an aqueous surfactant solution before stimulating treatment development of plants with a solution.

The proposed method can significantly accelerate the growth processes in the seed.

The following examples reveal the essence of the invention.

Example 1

Orenburg-10 wheat seeds were moistened with water and placed in a chamber in which the air pressure was raised to 0.8 atm, and then the pressure was released. The air that got into the seeds, when depressurizing, was supposed to exit, damage the seminal membranes, increasing the number of defects in them. Then the seeds were dried and treated with a solution of the drug "Albit" recommended concentration. As a comparison, seeds were used that were not subjected to pressure relief treatment, but only treated with a solution of the Albit preparation of the recommended concentration. After that, the seeds were dried and sown in small plastic cups with a diameter of 70 mm in black soil. Seeds were germinated in the dark for 3 days at a temperature of 22 ° C. The strength of seed growth after treatment with drugs was determined by the average length of the roots. The experiments were carried out in 10-fold repetition. The results are presented in table 1.

Table 1 Comparative seed treatment results A drug The average length of the roots, mm Albit (without pressure relief) 81.0 Albit (with pressure relief treatment) 107.5

From the data obtained it is clearly seen that the average root length of plants grown from seeds previously treated with pressure relief is almost 30% greater than that of plants grown from seeds treated with a solution of Albit alone.

Example 2

Orenburg-10 wheat seeds were moistened with water and placed in a chamber in which the air pressure was raised to 1.0 atm, and then the pressure was released. The air that got into the seeds, when depressurizing, was supposed to exit, damage the seminal membranes, increasing the number of defects in them. Then the seeds were dried and treated with a solution of the drug "Albit" recommended concentration. As a comparison, seeds were used that were not subjected to pressure relief treatment, but only treated with a solution of the Albit preparation of the recommended concentration. After that, the seeds were dried and sown in small plastic cups with a diameter of 70 mm in black soil. Seeds were germinated in the dark for 3 days at a temperature of 22 ° C. The strength of seed growth after treatment with drugs was determined by the average length of the roots. The experiments were carried out in 10-fold repetition. The results are presented in table 2.

table 2 Comparative seed treatment results A drug The average length of the roots, mm Albit (without pressure relief) 81.0 Albit (with pressure relief treatment) 153.5

From the data obtained, it is clearly seen that the average root length of plants grown from seeds previously treated with pressure relief is almost 2 times greater than that of plants grown from seeds treated with only the Albit solution.

Example 3

Orenburg-10 wheat seeds were moistened with water and placed in a chamber in which the air pressure was raised to 1.0 atm, and then the pressure was released. The air that got into the seeds, when depressurizing, was supposed to exit, damage the seminal membranes, increasing the number of defects in them. Then the seeds were dried and treated with a solution of the Fertigrain Start preparation of the recommended concentration. As a comparison, seeds were used that were not subjected to pressure relief treatment, but only treated with a solution of the Fertigrain Start preparation of the recommended concentration. After that, the seeds were dried and sown in small plastic cups with a diameter of 70 mm in black soil. Seeds were germinated in the dark for 3 days at a temperature of 22 ° C. The strength of seed growth after treatment with drugs was determined by the average length of the roots. The experiments were carried out in 10-fold repetition. The results are presented in table 3.

Table 3 Comparative seed treatment results A drug The average length of the roots, mm Fertigrain start (without pressure relief treatment) 89.5 Fertigrain start (with pressure relief treatment) 97.5

From the obtained data it is clearly seen that the average root length of plants grown from seeds previously treated with pressure relief is almost 10% greater than that of plants grown from seeds treated with only the Fertigrain Start solution.

Example 4

Orenburg-10 wheat seeds were moistened with a surfactant solution and placed in a chamber in which the air pressure was raised to 1.0 atm, and then the pressure was released. The air that got into the seeds, when depressurizing, was supposed to exit, damage the seminal membranes, increasing the number of defects in them. Then the seeds were dried and treated with a solution of the Fertigrain Start preparation of the recommended concentration. As a comparison, seeds were used that were not subjected to pressure relief treatment, but only treated with a solution of the Fertigrain Start preparation of the recommended concentration. After that, the seeds were dried and sown in small plastic cups with a diameter of 70 mm in black soil. Seeds were germinated in the dark for 3 days at a temperature of 22 ° C. The strength of seed growth after treatment with drugs was determined by the average length of the roots. The experiments were carried out in 10-fold repetition. The results are presented in table 4.

Table 4 Comparative seed treatment results A drug The average length of the roots, mm Fertigrain start (without pressure relief treatment) 89.0 Fertigrain start (with pressure relief treatment) 100.5

From the obtained data it is clearly seen that the average root length of plants grown from seeds previously treated with pressure relief is almost 10% greater than that of plants grown from seeds treated with only the Fertigrain Start solution.

Thus, the present invention can significantly increase the sowing quality (growth rate) of seeds.
