Description

The invention relates to agriculture, preferably to the technology of presowing treatment of seeds.

A known composition for regulating plant growth based on active ingredients, including ammonium molybdenum acid, potassium sulfate and a salt of a copolymer of methacrylic acid and its ester (RU, patent No. 1592970, C1 IPC ⁶ A01N 59/16, A01N 59/02, A01N 37/06, А01С 1/00, А01N 59/16, А01N 59/02, А01N 37/06, Composition for regulating plant growth / G.G. Bazunova, AMDavydov, A.A. Kashin et al. (RU) - Application No. 4632616/15).

The disadvantages of the described composition should be attributed to the fact that the composition increases the yield of wheat by 20-40%, while the processing of sunflower seeds increases the yield of its green mass, the dosage of each component of the mixed composition should be determined based on the quality of the seed material of each batch of seeds.

There is also known a method of stimulating plant growth, including treating seeds and watering the plants during the growing season with an aqueous solution containing hydrogen peroxide 10 ^-6 -10 ^-4 mol / l and copper ions 10 ^-6 -10 ^-5 g-ion / l and oxalic acid in an amount of 0.1-0.2 mg / l (RU, patent No. 2088086. C1. АN 59/00. A method of stimulating plant growth / G.A. Pirumyan [AM], CK.Khachaturian [AM], Yu.I. . Skurlatov [RU] and others. - Application 5030411/13).

The disadvantage of this composition is the one-sided effect of its use.

In addition to the described methods, there is a known method of stimulating plant growth with aqueous solutions of saturated dicarboxylic acids, such as malonic, oxalic, malic or succinic acids, when they are concentrated in an aqueous solution of 10 ^-11 -10 ^-15 mol / l (RU, patent No. 2267924. C1. IPC. А01N 37/04 (2006.01) A method of stimulating plant growth / A.L. Vereshchagin, V.V. Kropotkina, S.S. Akimova (RU) and others - Application 20044132060/04).

The disadvantages of this method include its use in one crop - radish, the seed treatment of which was carried out by soaking. This narrows the range of its application and manufacturability.

A close analogue of the comparison according to the principle of selecting bio-rational agents according to the mechanism of action is a composite composition for treating plants and their organs containing a polymer film former, target additives and a solvent, in which it contains a carbomide-formaldehyde resin as a polymer film former, water as a solvent, and water as a solvent targeted additives, it contains alkali metal stearate, sodium salt of humic acid, liquid macronutrients, including liquid complex fertilizers and / or sul fop copper growth stimulator - 1-etoksisilatran crop protection and in the following ratio, wt%: Urea Resin (dry residue) 0.1-1.0;. alkali metal stearate 0.001-0.05; humic acid sodium salt 0.005-0.15, liquid macronutrients 1.0-45.0; trace elements 0.1-2.0; 1-ethoxysilatran 0.001-001; plant protection products 0.1-20.0; water - the rest (RU, patent No. 2092004. C1. IPC ⁶ A01C 1/06. Composition for treating plants and their organs / V.P. Baryshok, M.G. Voronkov (RU), E.G. Ilyina (BY ) and others. - Application No. 5055417/13).

Despite the fact that the selection of components is made taking into account their physical and chemical activity, the ability to combine with other components of the composition, the variation of the component composition and their mass fraction in the composition are determined by the specific conditions for growing crops, and not by the physiological needs of plants, determined by the quality of seeds plant diagnostics.

A known method of protecting plants from diseases and regulating their growth according to Slavic technology, including treating plants with humic compounds and multicomponent growth regulators based on them, in which, immediately before application to plants, their organs and seeds, is introduced into the working fluid, along with humic compounds, protectively a stimulating complex in a ratio of 1: 1-1: 210, respectively, which includes ammophos, copper sulfate, urea, ammonia and / or sodium carbonate, with the introduction of other substances into the complex, for example, fungicidal and using different combinations of components depending on the types of crops and the timing of plant development, while the working fluid can be applied starting from seed dressing, and vegetative plants are treated at their height from 0.001 meters to flowering and later (RU, Application for invention No. 98100115/04. A. IPC ⁶ A01N 59/00, A01N 61/00. A method of protecting plants from diseases, regulating their growth according to Slavic technology and a protective and stimulating complex for its implementation / V.I. Klimenko).

The disadvantages of the composition include the fact that when creating and using semi-functional preparative forms, their effectiveness is determined by the correct selection of the ratio of components, which is determined either by the quality of the seeds (for pre-sowing seed treatment) or the diagnosis of mineral nutrition of plants (for vegetative treatment of plants). A limiting factor in the widespread use of this technique is the availability of certain formulations to obtain a composition.

Known compositions for protecting plants from pathogens by pre-sowing treatment of seeds and planting material, treatment of vegetative plants or soil composition based on aqueous solutions of chitosan, containing various organic acids and biologically active substances. For the treatment of barley seeds, the following composition is used, wt.%: Chitosan - 0.3, succinic acid - 0.2, glutamic acid - 0.06, heteroauxin - 0.006, salicylic acid - 0.06, catapol - 0.3, water - up to 100 (RU patent No. 2158510. C2. IPC ⁷ A01N 25/00, A01N 37/04, A01N 37/44, F01T 57/18. Composition for increasing the resistance of plants to diseases (options) / K.V. Novozhilov , S.L. Tyuterev, S.A. Tarlakovsky et al. (RU) - Application 97107927/13).

The disadvantages of the proposed composition include only an assessment of the biological effectiveness of the claimed composition against root rot, helminthosporious leaf spot, rhinchosporiasis and septoria and the lack of data against pathogens of smut smut, rust, etc.

The closest means for pre-sowing seed treatment of agricultural crops includes a liquid-based preparation, presented in a method for pre-sowing seed treatment of cereals, legumes, cereals and oilseeds, including the treatment of seed with a solution of natural bischofite mineral, 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 bischofite brine used for seed treatment is activated with a magnetic field with a capacity of 200-450 Oe (RU, patent No. 2224399. C2. IPC ⁷ А01С 1/00. The method of presowing treatment of seeds of grain, leguminous, cereal and oilseeds / A.V. Lomtev, A .A. Astakhov, AMSaldaev (RU) .- Application No. 2002102139/12; Stated January 23, 2002; Published on February 27, 2004, Bulletin No. 6 // Inventions. Useful models. - 2004. - No. 6).

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 treatment of seeds of a wide range of agricultural crops using products that are common and available in agriculture, 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 quality of agricultural products, as well as resistance to pests.

The specified technical result is achieved by the fact that in the known tool for presowing 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, copper sulfate and Mohr's salt are additionally introduced in the following ratio of components , wt.%:

In the fourth embodiment, nicotinic acid is additionally introduced into the solution in the following ratio of components, wt.%:

Natural mineral bischofite (brine) - 30-60 A nicotinic acid - 0.02 Salt Mora - 0.40 Water - the rest

In the fifth embodiment, salicylic acid is additionally introduced into the solution in the following ratio of components, wt.%:

Natural mineral bischofite (brine) - 6070 Salicylic acid - 0.005 Salt Mora - 0.40 Water - the 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 brine of the natural mineral bischofite with a density of 1.30-1.32 t / m ³ . To increase the efficiency, copper sulfate and Mora salt are additionally introduced into the solution in the following ratio of components, wt.%:

Natural mineral bischofite (brine) - 40-60 Blue vitriol - 0.30-0.40 Salt Mora - 0.40 Water - the rest

Seed treatment 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, anat-25K, albite, arachidonic acid, silk, biosil, fusicoccin, crezacin, mival, zircon, succinic acid, sodium and potassium salts of humic acids and others (“List of pesticides and agrochemicals permitted for use in the Russian Federation. 2004. Reference publication. - 576 p. ").

However, each of these drugs separately does not give the desired result.

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

Bischofite (brine density 1.30-1.32 t / m ³ ) - 40 Blue vitriol - 0.3 Salt Mora - 0.4 Water - the rest

on the sowing quality of seeds and yield formation of millet of the Kamyshinskoye variety 95. The main information is presented in Tables 1 and 2.

Establishment of optimal concentrations of preparations for composite mixtures in Petri dishes showed that when treating millet seeds with bischofite of 40% concentration, seed germination energy was 85.3%, and germination rate was 90.2%, while the plant length was 9.9, and the length of the main root is 7.2 cm, with a mass of 10 plants 0.485 g. Seed treatment with a composite mixture containing 40% bischofite, copper sulfate 0.3%, Mora salt 0.4%, increases these parameters to 86.0 and 91, 1%, 10.5 and 7.3 cm and 0.594 g (Table 2).

Example 2. Consider the effectiveness of the funds having the following composition, wt.%:

Bischofite (brine) - 40 Potassium humate - 3,5 Salt Mora - 0.4 Water - the rest

on sowing quality of seeds, morphological indicators of plants and the yield of millet of the Kamyshinskoye variety 95.

Seed treatment and germination in Petri dishes showed that when treating millet seeds with a 40% concentration of bischofite solution, the seed germination energy was 85.3%, and the germination rate was 90.2%. The length of the plant was 9.9, the length of the main root was 7.2 cm, and the weight of 10 plants was 0.485 g. Seed treatment with a composite mixture consisting of bischofite of 40% concentration, potassium humate 3.5% and Mora salt 0, 4%, increased these indicators, respectively, to 86.2 and 91.3%, 11.1 and 8.0 cm and 0.667 g (Table 2).

Example 3. Consider the effectiveness of the means for presowing treatment of seeds of agricultural crops, which has in its composition, wt.%:

Bischofite (brine) - 60 Albite - 0.20 Salt Mora - 0.40 Water - the rest

The effectiveness of this composition was tested on sunflower hybrid Kuban 930. The results obtained in the field are presented in table 3-5.

The establishment of optimal concentrations of preparations for composite mixtures in Petri dishes showed that when treating sunflower seeds with bischofite 60% concentration, the seed germination energy was 93.5, and germination rate was 96.2%, with a plant length of 15.5, and the main root - 8.9 cm and a weight of 10 plants 10.7 g. When treating seeds with a growth-promoting composition: bischofite 60% + albite 0.20% + Mora salt 0.4%, these figures respectively increased to 93.3 and 95.8%, 15 , 2 and 11.1 cm and 15.5 g (Table 5).

Example 4. Consider the effectiveness of the following composition on the sowing quality of seeds, morphological parameters of plants and the formation of a crop of barley variety Donetsk 8, wt.%:

Bischofite (brine) - thirty A nicotinic acid - 0.20 Salt Mora - 0.40 Water - the rest

Preliminary determination of the concentrations of the preparations in Petri dishes for compositional seed treatment showed that when barley seeds were treated with a 30% bischofite concentration, the seed germination energy was 90.9, and germination rate was 92.6%, with a plant length of 9.2, and the main root - 7.0 cm and a mass of 10 plants of 2.28 g.

Seed treatment with a composite mixture containing bischofite 30%, nicotinic acid 0.02%, Mora salt 0.4%, these indicators respectively increased to 91.1 and 93.0%, 10.5 and 7.8 cm and 2.59 g (table 7).

The effectiveness of this composition is tested under production conditions and is shown in table.6.

Example 5. Consider the effectiveness of a composition having the following composition on the sowing quality of seeds and productivity of sunflower hybrid Kuban 930, wt.%:

Bischofite (brine) - 60 Salicylic acid - 0.005 Salt Mora - 0.40 Water - the rest

Establishing the concentrations of preparations in Petri dishes for compositional treatment of seeds showed that when seeds were treated with a bischofite solution of 60% concentration, the seed germination energy was 93.5, and germination rate was 96.2%, with a plant length of 12.5, and the main root 8.9 cm and a weight of 10 plants 10.7 g. Seed treatment with a composite mixture consisting of bischofite 60% + salicylic acid 0.005% + Mora salt 0.4%, increased these indicators to 93.0 and 96.7%, respectively 14.5 and 10.3 cm and 14.9 g (Table 5).

The results of experiments under production conditions are shown in Tables 3 and 4.

Potassium humate liquid peat (HA) is a complex organo-mineral fertilizer. The main active ingredient of the drug is physiologically active forms of potassium salts of humic acids (80.0 g / l), fulvic acids (2.0 g / l). Also, the composition of the drug includes amino acids, carbohydrates, water-soluble carboxylic acids (oxalic, succinic, malic, citric), mineral nutrition elements (nitrogen, phosphorus, potassium) and biologically active forms of trace elements (iron, zinc, manganese, boron, molybdenum).

When treated with a drug, seed germination increases, germination energy stimulates the growth and development of plants at all stages of ontogenesis. The drug contributes to the intensification of physiological and biochemical processes, the accumulation of nutrients, the growth of biomass and increased plant resistance to adverse environmental factors and diseases.

Nicotinic acid (NK) - vitamin B ₅ or PP, formula C ₆ H ₅ O ₂ N - is involved in the metabolism of carbohydrates, proteins, phosphorus and other substances important for plants. It participates in redox processes and is part of many enzymes.

Salt Mora is a sulfate salt of ammonium and iron of the formula (NH ₂ ) ₂ [SO ₄ ] · FeSO ₄ · 6H ₂ O. Iron plays an important role in biochemical processes in plants. Iron-containing proteins and enzymes are known: ferredoxin, cytochromes, peroxidase, catalase, hemogabin of legume nodules, etc. When the seeds are enriched with iron, the activity of these enzymes increases.

The trace element copper forms copper-containing enzymes, affects the biosynthesis of chlorophyll, participates in the processes of respiration and nitrogen metabolism, increases the biosynthesis of amino acids and the fixation of molecular nitrogen. It has been established that the activity of nitrate reductase in plants increases under the influence of copper.

Seed treatment with copper sulfate increases the energy of germination and germination of seeds and significantly stimulates the growth of seedlings by providing seeds with tryptophan, which is involved in the formation of growth stimulants.

Salicylic acid - hydroxybenzoic acid, the simplest aromatic hydroxy acid of the formula C ₇ H ₆ O ₃ is an endogenous growth regulator with not only growth-promoting, but also clearly pronounced anti-stress activity, which together provides increased resistance to fungal diseases and plant productivity.

Albite contains purified active substances from soil bacteria Bacillus megaterium and Pseudomonas aureofaciens. Under natural conditions, these bacteria live on the roots of plants, stimulate their growth, protect against diseases and adverse environmental conditions. The composition of the preparation also includes a balanced starting set of macro- and microelements (N, P, K, Mg, S, Fe, Mn, Cu, Zn, Mo, Na, B, Co, Ni, Cl, Ca, Se, Si) and terpene acids of coniferous extract.

Albit combines the advantages of such well-proven analogue drugs as agate-25K, pseudobacterin-2, planriz, phytosporin, silk, novosil, ecost, aquarin, crystals, humates. Unlike biological products containing living microorganisms, the effect of albite is stable, less affected by environmental conditions. Albit stably increases the yield of cereals, sugar beets, sunflowers, potatoes, flax, vegetables, legumes, fruit crops, and forage grasses by 12-23% (V.T. Alekhin, A.K. Zlotnikov. Albit biological product: results and application features. / Agriculture, 2006. - No. 3. - S.38-40).

Thus, the above technical result is also achieved by the fact that in the method for producing a presowing composition, the concentration of bischofite brine of the formula MgCI ₂ · 6H ₂ O is sequentially selected depending on the quality of the seeds, which is assigned according to the best seed germination and germination energy, root length and seedling, as well as the mass of the plant.

The dose of consumption of potassium humate, albite, Mohr's salt, copper sulfate, nicotinic acid and salicylic acid is prescribed in the same way as the brine of the natural mineral bischofite only against the background of the prescribed concentration of bischofite.

Potassium humate, albite, copper sulfate, nicotinic acid, salicylic acid, and Mohr's salt are dissolved in the recommended rate of water, to which bischofite brine is added and mixed thoroughly.

For the speed and completeness of the dissolution of salicylic acid, nicotinic acid, copper sulphate and Mohr's salt, they are dissolved in water heated to 60 ° C.

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

The effectiveness of pre-sowing treatment of millet seeds is presented in table 1, sunflower in tables 3 and 4, and barley in table 6.

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

The information presented convincingly indicates the achievement of the task. We use the natural environmentally friendly mineral bischofite in a mixture with potassium humate, nicotinic acid, salicylic acid, copper sulfate, albite and the Mohr's salt as a growth promoter.
