Description

The invention relates to agriculture, in particular to preparations for increasing crop yields.

Known means to increase productivity, in which tetrahydrofuranol-3 formulas are used as a plant growth stimulator

(Patent RU No. 2127053 C1, IPC ⁶ A01N 43/08) “Plant Growth Stimulator / R.F. Galipov, A. M. Gaisin, M. G. Safarov and others. Claimed 18.10.1995, publ. 03/10/1999). Using it allows you to increase the germination of seeds, increase bushiness, mass of grain, accelerate rooting.

The disadvantage of using this tool should be considered a unilateral action and the need for soaking seeds before sowing, which is a low-tech technique.

One of the most common plant growth stimulants of plants of plant origin is the drug Silk (R.T. Rodionova. Silk - reliable protection and yield increase // Fertility. - No. 1 (10). - 2003. - P.16). Silk is used in the form of an aqueous solution of optimal concentration of 50-60 ml / t (Booklet of ELHA-SILK CJSC. Silk - saving money and effort. - 4 pp.).

The disadvantage of these recommendations is the close consumption of the drug for use on 19 crops permitted by the State Chemical Commission of the Russian Federation, which significantly differ from each other in biology and cultivation technologies.

A close analogue of the comparison to the claimed structure and effect is the use of a mixture of natural terpene compounds isolated from coniferous balsams - the preparation terpenol - as a growth stimulator for plants of the cereal, nightshade, pumpkin, haze, cruciferous, lilac, mulberry, and asteraceae families (application for invention RU No. 981123009 A, 7 A01N 61/00. Plant Growth Stimulator / P. I. Fedorov, L. P. Bazylchik, V. V. Anisimov et al .; Declared December 21, 1998, publ. October 20, 2000).

The closest means for pre-sowing treatment of crops is a liquid-based preparation, presented in a method for pre-sowing treatment of seeds of cereals, legumes, cereals and oilseeds, including the treatment of seed with a solution of the natural mineral bischofite, in which the seeds are treated with a bischofite solution with a concentration of 15-100 wt.% of the initial brine and a flow rate of 10-15 l / t of seeds, taking into account the type of seeds, their germination, germination energy and density of the bischofite brine, while for seed treatment, bischofite brine is activated with a magnetic field with a capacity of 200-450 Oe (patent RU No. 2224309 C2, IPC ⁷ A01C 1/00. The method of presowing treatment of seeds of cereals, legumes, cereals and oilseeds / A.V. Lomtev, A.A. .Astakhov, A.M.Saldaev (RU) .- Application No. 2002102139/12).

The disadvantages of the described method in relation to the problem we are solving are that the induction of a magnetic field on the seeds is short-term and requires special expensive equipment.

The essence of the claimed invention is as follows.

The problem to which the claimed invention is directed is to increase the efficiency of pre-sowing seed treatment of a wide range of agricultural crops using common cheap and affordable agricultural products, as well as expanding the range of growth-promoting agents for agricultural crops due to better compatibility and synergy of bio-rational agents.

The technical result is an increase in yield and product quality, as well as their resistance to pests.

The specified technical result is achieved by the fact that in the known tool according to the first embodiment for pre-sowing treatment of seeds of agricultural crops, containing an aqueous solution of brine of the natural mineral bischofite with a density of 1.30-1.32 t / m ³ , according to the invention, they are additionally introduced silk, vitamin B ₁₂ and vitamin C in the following ratio of components, wt.%:

Natural mineral bischofite (brine) 35-55 Silk 0, 1-0,2 Vitamin B ₁₂ 0.01-0.03 Vitamin C 0.01-0.02 Water Rest.

Silk, nicotinic acid and vitamin B _{6 are} additionally introduced into the means for presowing seed treatment according to the second filling variant in the following ratio of components, wt.%:

Natural mineral bischofite (brine) 35-55 Silk 0.1-0.2 A nicotinic acid 0.01-0.02 Vitamin B ₆ 0.01-0.03 Water Rest.

Silk, nicotinic acid and vitamin C are additionally introduced into the solution according to the third variant of the set of components in the solution in the following ratio of components, wt.%:

Natural mineral bischofite (brine) 35-55 Silk 0.1-0.2 A nicotinic acid 0.01-0.015 Vitamin C 0.01-0.02 Water Rest.

Silk, nicotinic acid and vitamin B _{12 are} additionally introduced into the composition according to the fourth embodiment, in the following ratio of components, wt.%:

Natural mineral bischofite (brine) 45-50 Silk 0.10-0.15 A nicotinic acid 0.01-0.02 Vitamin B ₁₂ 0.01-0.03 Water Rest.

Silk, para-aminobenzoic acid (PABA) is additionally introduced into the agent according to the fifth embodiment in the following ratio of components, wt.%:

Natural mineral bischofite (brine) 35-50 Silk 0.1-0.15 PABK 1.5 -2.5 Water Rest.

The invention is illustrated by examples and results of experimental data presented in tables 1-7.

Information confirming the possibility of implementing the claimed invention are as follows.

Means for presowing treatment of seeds of agricultural crops contains an aqueous solution of the natural mineral bischofite with a density of 1.30-1.32 t / m ³ . To increase the efficiency, the solution according to the first filling option was additionally introduced with Silk, Vitamin B ₁₂ and Vitamin C in the following ratio of components, wt.%:

Natural mineral bischofite (brine) 35-55 Silk 0.1-0.2 Vitamin B ₁₂ 0.01-0.02 Vitamin C 0.01 Water Rest.

Processing of seeds of crops is carried out at the rate of 10 liters of the composite mixture per ton of seeds. Numerous chemical compounds are known that are used as plant growth regulators: ambiol, albite, arachidonic acid, silk (biosil), potassium humate, mival, symbiont, zircon, epin, succinic acid and others (“List of pesticides and agrochemicals approved for use on the territory of the Russian Federation. ”2004. Reference publication. - P.576).

However, each of these preparations during pre-sowing treatment of seeds separately does not give the desired result.

Example 1. Consider the effectiveness of this tool having the following composition of the tank mixture of biorational products, wt.%:

Bischofite (brine density 1.30-1.32 t / m ³ ) 35-55 Silk 0.10-0.15 Vitamin B ₁₂ 0.01-0.02 Vitamin C 0.01-0.03 Water Rest

for seed germination and the formation of a grain yield of barley and oilseeds of sunflower when using the composition, are presented in tables 3-7.

The establishment of optimal concentrations of preparations for composite mixtures in Petri dishes showed that when treating barley seeds with bischofite, a 35% concentration in a mixture with a 0.10% crop was used, seed germination energy was 85.0%, and germination rate was 88.1%, while the plant length (seedling) was 9.2, and the length of the main root was 6.5 cm, with a mass of 10 plants 1.93 g. Seed treatment with a composite mixture: bischofite 35%, silks 0.10%, vitamin B ₁₂ 0.01% and Vitamin C 0.01% increases these indicators to 85.7 and 88.2%, 11.6 and 7.9 cm and 2.51 g (table 7).

When treating Temp hybrid sunflower seeds with a solution of bischofite brine of 35% concentration in a mixture with a crop, 0.10%, these figures were 90.1 and 95.0%, 10.8 and 10.3 cm and 9.5 g, respectively when treating seeds with the composition: bischofite, 35% + silk, 0.10% + vitamin B ₁₂ , 0.01% + vitamin C, 0.01% they were 90.3 and 95.6%, 12.4 and 11, respectively , 0 cm and 12.6 g (table 5).

Example 2. Consider the effectiveness of the means having the composition of the components according to the second option for germination and yield of barley and sunflower, wt.%:

Bischofite (brine density 1.30-1.32 t / m ³ ) 35-55 Silk 0.10-0.15 A nicotinic acid 0.01-0.02 Vitamin B ₆ 0.01-0.03 Water Rest.

Processing the seeds and germinating them in Petri dishes on the Sunflower hybrid Temp showed that when treating the seeds with a bischofite solution of 55% concentration in a mixture with a crop, 0.10% the seed germination energy was 90.1 and 95.0%. The length of the plant was 10.8 and 10.3 cm; with a weight of 10 plants 9.5 g. Seed treatment with a composite mixture consisting of 55% concentration of bischofite, silka, 0.10%, nicotinic acid, 0.01% and vitamin B ₆ , 0.01, increased these indicators, respectively, to 90 5 and 95.5%, 11.6 and 10.7 cm (table 5).

When treating barley seeds with a bischofite solution of 35% concentration in a mixture with a silk, 0.10%, these indicators were 85.0 and 88.1%, 9.2 and 6.5 cm and 1.93 g, while when treating seeds with a composition : bischofite, 35% + silk, 0.10% + nicotinic acid, 0.01% and vitamin B ₆ , 0.01%, respectively, they were 85.5 and 88.3%, 9.4 and 6.5 cm and 2.16 g (table 7).

Silk is a mixture of triterpenic acids extracted from Siberian fir needles, has a pronounced growth-stimulating effect, causing enhanced growth of the root system with the formation of secondary roots, increases germination and seed germination energy, increases yield by 10-30% and improves the quality of products of various crops induces in plants non-specific resistance to diseases and adverse environmental factors, inhibiting the development of a wide range of pathogens of the main agricultural diseases agricultural crops (Rodionova RT Silk - reliable protection and yield increase // Fertility, - No. 1 (10). - 2003. - P.16).

Nicotinic acid or vitamin B ₅ , also known as PP, of the formula C ₆ H ₅ O ₂ N; vitamin B ₆ (adermin or pyridoxine) of the formula C ₈ H ₁₁ O ₃ N; vitamin H ₁ (para-aminobenzoic acid of the formula C ₇ H ₇ O ₂ N, vitamin B ₁₂ (no synonyms) formula C ₆₃ H ₈₈ N ₁₈ O ₁₃ C ₀ P; vitamin C or ascorbic acid of the formula C ₆ H ₈ O ₆ intensify the metabolism increase seed germination.

Under the influence of nicotinic acid in the seeds, the hereditary characteristics of the plant change. It was noted that in such seeds the content of RNA and DNA, as well as basic and acidic proteins, increases phosphorus metabolism, as well as the formation of other vital compounds. Niacin is involved in the conversion of glutamic acid, cytochrome, nitrates and nitrites, respectively, to nitrates and nitric oxide, ammonium to betainaldehyde, galacturonic acid ester to L-galacton-γ-lactone, i.e. ascorbic acid precursor, which, with the participation of cytochrome oxidase, is converted to vitamin C in the reaction of converting D-3-phosphoglyceric aldehyde to D-3-phosphoglyceric acid, as well as malonic acid to pyruvic acid, cysteine to cystine, oxidized glutathione to reduced glutathione.

Vitamin B ₆ provides transamination reactions and assimilation of ammonium. Pyridoxine is also involved in the biosynthesis of γ-aminobutyric acid, which is formed during seed germination. Thus, with a deficiency of this vitamin, many aspects of amino acid metabolism are disrupted.

Under the influence of other vitamins, the activity of enzymes in germinating seeds increases, the processes of neoplasm of vital compounds are stimulated. The beneficial effect of vitamins can be associated not only with their direct effect on seeds, but also with a change in the composition of soil microflora.

Example 3. Consider the effectiveness of the funds according to the third option for presowing treatment of seeds of agricultural crops, having in its composition, wt.%:

Bischofite (brine) 35-55 Silk 0.10-0.20 A nicotinic acid 0.01-0.15 Vitamin C 0.01-0.02 Water Rest.

The effectiveness of this tool was tested on winter wheat, barley and sunflower. The results obtained in the field experiments are presented in tables 1, 3, 4 and 6.

Establishment of optimal concentrations of the preparation for composite mixtures in Petri dishes showed that when treating winter wheat seeds with bischofite, a 45% concentration in a mixture with a 0.015% silica was found to have a seed germination energy of 88.9, a germination rate of 91.2%, and a plant length of 10.1 and the length of the main root is 7.5 cm, with a mass of 10 plants 2.35 g. Seed treatment with the composite mixture: bischofite, 45% + silk, 0.015% + nicotinic acid, 0.01% and vitamin C, 0.01% increases these indicators, respectively, to 90.0 and 94.3%, 11.0 and 8.5 cm and 2.51 g (table 2).

Example 4. Consider the effectiveness of the proposed funds for the fourth option in the following composition, wt.%:

Bischofite (brine) 45-50 Silk 0.10-0.15 A nicotinic acid 0.01-0.02 Vitamin B ₁₂ 0.001-0.03 Water Rest.

The selection of the most effective compositions for pre-sowing treatment of seeds of winter wheat found that seed treatment with a 45% concentration of bischofite brine in the mixture was strong, 0.15% seed germination energy was 88.9, and germination rate was 91.2%, while the seedling length was 10 , 1, the length of the main root is 7.5 cm, and the weight of 10 plants is 2.35 g. When treating seeds with a growth-stimulating composition: bischofite brine, 45% + silk, 0.15% + nicotinic acid, 0.01% + vitamin At ₁₂ , 0.01%, these indicators, respectively, were 90.1 and 93.8%, 10.5 and 8.0 cm and 2.47 g (table 2). The effectiveness of this tool was tested in production conditions during the cultivation of winter wheat (table 1).

Example 5. The drug according to the fifth embodiment has the following composition, wt.%:

Bischofite (brine) 35-50 Silk 0.10-0.15 PABK 1.5-2.5 Water Rest.

The effectiveness of this tool was tested in production conditions when cultivating barley (table 6).

Seed treatment and germination of spring barley in Petri dishes showed that when treating seeds with bischofite brine, 35% concentration in a mixture with a crop, 0.10%, the seed germination energy was 85.0, and the germination rate was 88.1%. The length of the plant was 8.2, the length of the main root was 6.5 cm, and the weight of 10 plants was 1.93 g. Seed treatment with a composition consisting of a 35% concentration of bischofite brine, silk, 0.10% and PABA, 1 , 50% increases these indicators to 86.0 and 88.7%, 10.7 and 7.4 cm and 2.38 g, respectively (table 7).

Thus, the above technical result is also achieved by the fact that in the method for producing a pre-sowing composition, the concentrations of bischofite brine of the formula MgCl ₂ · 6H ₂ O and a silk are successively selected depending on the quality of the seeds, which is assigned according to the best germination energy and germination of seeds, the length of the seedling and roots, as well as the mass of the plant.

The dose of nicotinic acid, vitamins B ₆ , B ₁₂ and C, as well as PABA, is prescribed in the same way as the brine of the natural bischofite mineral, only against the background of a mixture of bischofite with a strong, for which the silk is introduced into bischofite and mixed thoroughly.

Nicotinic acid, para-aminobenzoic acid and vitamins B ₆ , B ₁₂ and C are dissolved in the recommended rate of water heated to 40-60 ° C, which is added to the bischofite brine with a pot and mixed.

Seed treatment is carried out before sowing at the rate of 10 liters per ton of seeds.

The effectiveness of pre-sowing treatment of winter wheat seeds is presented in table 1, sunflower in table 3, and spring barley in table 6.

Presowing treatment of seeds with tank mixtures of biorational products, as shown by the data in tables 1, 3, 6, helps to improve the quality of the products obtained while improving the phytosanitary situation in crops.

The information presented convincingly proves the achievement of the task. We use a natural eco-friendly mineral bischofite as a growth promoter in a mixture with a plant growth regulator based on renewable plant materials - by force and adding vitamins: nicotinic and para-aminobenzoic acids, as well as vitamins B ₆ , B ₁₂ and C.
