Description

The invention relates to the field of agriculture and is intended for presowing treatment of seeds.

It is known to use the growth preparation Mival and bischofite solution for presowing treatment of seeds of grain crops (RF patent No. 2316163 C2, class A01C 1/00).

It is known to use an aqueous solution of a disinfectant and complex microfertilizer in the chelate form of Aquamix (RF patent No. 2267924 C1, class A01N 37/04).

It is known to use aqueous solutions of hydrogen peroxide, copper ions and oxalic acid for treating seeds of grain crops and spraying plants during the growing season (RF patent No. 2088086, class A01N 37/06).

Known drugs can increase productivity, but require several operations during processing and are difficult to prepare.

The technical problem solved by the invention is to increase the efficiency of pre-sowing treatment of seeds of grain crops using common cheap and affordable agricultural products, as well as expanding the range of tools for pre-sowing seed treatment.

The technical result is an increase in the energy of germination and germination of seeds, as well as the yield of grain crops.

The technical result is achieved by the fact that the seeds of grain crops are treated with a complex fertilizer containing complexes of hydroxyethylidene diphosphonic acid (OEDPK) with trace elements, as well as H ₃ VO ₃ and K ₃ PO ₄ in g / l of water:

Mn · C ₂ H ₇ O ₇ P ₂ · 2H ₂ O - 1.71

Cu · 2C ₂ H ₇ O ₇ P ₂ · 4H ₂ O - 0.64

Mo · C ₄ H ₁₁ O ₁₆ P ₄ · 3NH ₄ · 6.75H ₂ O - 0.27

Zn2C ₂ H ₇ O ₇ P ₂ 4H ₂ O - 0.71

Co · C ₄ H ₁₆ O ₁₆ P ₄ · C ₄ H ₁₄ N ₂ - 1.65

N ₃ VO ₃ - 0.50

K ₃ PO ₄ - 0.78

Means for presowing treatment of seeds is an aqueous solution of gray color, odorless; The composition includes minerals in the form of complex compounds of HEDPA with microelements (Mn, Cu, Mo, Zn, Co), potassium phosphate and boric acid.

The invention is illustrated by the following examples.

Example 1. Laboratory experiments.

Study of the effect of presowing seed treatment on germination and germination of seeds of grain crops.

Assessment of biological activity as a means was carried out on the seeds of spring wheat cultivar Moskovskaya-35. The determination of germination energy and laboratory germination was carried out according to GOST 12038-84. Germination energy - percentage of germinated seeds in 3 days, laboratory germination - percentage of germinated seeds in 7 days.

In each Petri dish on two layers of moistened filter paper, 100 pieces of spring wheat seeds of the Moskovskaya-35 variety were evenly distributed. After that, the seeds were poured with 10 ml of nutrient solution and placed in a thermostat. Seeds were germinated at a temperature of 27.5 ± 2 ° C for 7 days.

Germination energy and laboratory germination of seeds soaked in the test solution were compared with germination energy and laboratory germination of seeds soaked in distilled water. The experiment was laid in four repetitions.

The arithmetic average of the results of determining the germination energy and laboratory germination of the analyzed samples was taken as the result of the analysis.

Wheat seeds of the Moskovskaya-35 variety are soaked in distilled water (control) and in the solution of the proposed product for 2 hours at the rate of 1 liter of solution per 1 kg of seeds. After soaking, the seeds are dried to the sowing condition, stored in paper bags and sown. Comparative data on the energy of germination and germination of seeds are given in table 1.

Table 1 Effect of presowing seed treatment on germination energy and laboratory germination of spring wheat seeds of the Moskovskaya-35 variety Experience Options Germination energy,% Germination,% The control 67.4 82.8 Experience 78.3 93.1

From the analysis of table 1 shows that the means for presowing treatment of seeds has a significant stimulating effect.

Example 2. Field experiments.

Study of the effect of presowing seed treatment on the yield of spring wheat of the Moskovskaya-35 variety.

On medium loamy gray forest soils with a humus content of 3.24%; mobile phosphorus - 145.0 mg / kg; exchange potassium - 135.0 mg / kg; a culture was grown - spring wheat of the Moskovskaya-35 variety. The method was carried out with four repetitions. The total area of the experimental plot was 80 m ² .

Stimulation of spring wheat plants of the Moskovskaya-35 variety in field experiments was carried out by soaking the seeds. In control plots, the seeds were soaked with water.

Comparative yield data are given in table 2.

table 2 The effect of pre-sowing treatment with a presowing seed treatment on the yield of spring wheat of the Moskovskaya-35 variety Experience Options Productivity, t / ha % to control The control 23.4 ± 0.09 - Experience 34.8 ± 0.11 11,4

From the data of Tables 1 and 2 it follows that when treated with a presowing seed treatment, the germination energy increases by 10.9%, germination - by 10.3%; productivity - by 11.4%.

Thus, the use of presowing seed treatment means can significantly increase the energy of germination and germination of seeds, as well as the yield of wheat of the Moskovskaya-35 variety, and allows you to expand the range of plant growth stimulants used. The possibility of using low concentrations while ensuring high stimulating efficiency, taking into account its comparative availability and low cost, distinguishes the agent for presowing seed treatment from the currently used agents.
