Description

The invention relates to the field of agriculture, namely to crop production, and can be used in farms engaged in the cultivation and primary processing of flax.

During the cultivation of many crops in Russia, the amount of work on plant protection decreased, which is due, first of all, to the high prices of drugs, fuels and lubricants, spare parts for the machine and tractor fleet. The issue of conformity of the manufactured products to environmental safety conditions is also acute, since fiber and seeds are the raw material for the production of tissues, cotton wool, medicines, oils, i.e. products with high hygiene requirements.

Flax suffers from many pests and diseases, and at all stages of ontogenesis. Seeds are also damaged. In flax growing, it is difficult to refuse the use of pesticides, which process both the seed material and the crops themselves. Agrotechnical measures aimed at protecting flax plants are only a necessary complement to their chemical protection. In the forefront in this situation is the creation of biological remedies, as well as chemicals that do not have toxic effects and aftereffect and do not accumulate in plants. When growing flax flax, various preparations are used for processing, as well as various cultivation techniques aimed at increasing the resistance of plants to adverse environmental factors and improving productivity [N.A. Kudryavtsev, M.M. Yanina, O. L. Ozersovskaya, V. .I. Bogomaz. The effectiveness and safety of the use of the drug "Ecost" in flax growing. Agrarian Russia. Scientific and Production Bulletin Ed. I.M. Dolotovsky, No. 1 (2), 1999, p.22-27].

It is known to use the drug Agat-25K for treating flax seeds and vegetative plants. Moreover, it exhibits fungicidal, bacterial and growth-regulating activity. The greatest effect when processing, for example, from diseases is achieved by combining the processing of seeds and vegetative plants in the phase of the "herringbone" and budding [N.A. Kudryavtsev. Agate-25 to protect flax. - Protection and quarantine of plants. 2001, No. 3, p.29-30].

It is known the use of a protective-stimulating agent "Ecost" for seed treatment and processing of crops. It can be used together with herbicides, insecticides and microelements [N.A. Kudryavtsev, M.M-Yanina. "Ecost" is a protective-stimulating composition recommended for use on flax culture. Results and prospects of development of selection, seed production, improvement of cultivation technology and primary processing of flax flax [Materials of the International scientific-practical conference dedicated to the 70th anniversary of the All-Russian Research Institute of Flax, held on November 16-18, 2000, Torzhok, 2000, p.132-133 , 247].

It is known to use slow-acting fertilizers containing humic substances, in particular oxyhumate or hydrohumate, which, in addition to fertilizing properties, exhibit growth-promoting properties. Various complex fertilizers are also used, containing additionally various regulators, for example phenomelan [Application of new mineral fertilizers with biologically active substances and microelements for flax flax. Recommendations, ed. T.V. Golchenko, Gorki, 2000, pp. 4-5], [S.P. Kukresh, S.F. Khodyakova, E.N. Gerasimenko. The effectiveness of micronutrient fertilizers in flax crops on soils of different particle size distribution. Actual problems of adaptive intensification of agriculture at the turn of the century. Materials of the international scientific-practical conference, June 16, 2000, Schuchin, Minsk, Belarusian Publishing Partnership "Khalta", 2000, p. 215-217], [S.L. Vedernik. Varietal responsiveness of flax to mineral nutrition levels and growth regulators. Actual problems of adaptive intensification of agriculture at the turn of the century. Materials of the international scientific-practical conference, June 16, 2000, Shchuchin, Minsk, Belarusian Publishing Partnership "Halta", 2000, p.227-229].

It is known to use preparations based on triterpenic acids (Novosil, Biosil, Silk) for treating plants [List of pesticides and agrochemicals approved for use in the Russian Federation, 2003].

However, we do not know the use of these drugs on flax flax.

The closest analogue is the method of growing flax flax, including autumn main and spring pre-sowing cultivation of the soil, pre-sowing seed treatment by seed dressing, sowing with high-quality seeds, crop maintenance, which consists in pre-emergence harrowing and seedling treatment with herbicides mixed with macro- and micronutrient fertilizers in phase "Christmas trees" for weed and disease control, harvesting with primary processing - dewlobe [Plant growing of the Central Black Soil region. / Ed. V.A. Fedotova. Center for Spiritual Revival of the Black Earth Region, Voronezh, 1998, pp. 433-439].

A significant drawback of the latter is the use of toxic substances without the possibility of reducing their consumption rate.

The above preparations are not cheap, they are difficult to prepare on the spot or they do not have the necessary complex effect, and their effects on many of the most important qualitative and quantitative parameters of the crop structure are not described in the literature.

It should also be noted that different varieties of flax flax may respond differently to fertilizers and complexes of growth regulators with herbicides and insecticides, so it is important to create protective and stimulating complexes that could be used with herbicides and insecticides on most cultivated varieties of flax long-haired.

The problem to which the invention is directed is to increase the yield of flax seeds and straw while improving the physico-mechanical characteristics of the stem and fiber, increase frost resistance, resistance to drought and lodging, pests and diseases, the lack of drug accumulation in plants with high efficiency and low consumption rate, environmental safety for the environment, a marked reduction in the cost of production and use of the drug.

This is the technical result.

The technical result is achieved by the fact that in the method of growing flax flax, including autumn main and spring presowing cultivation of the soil, presowing treatment of seeds, sowing with high-quality seeds, caring for crops, harvesting, according to the invention, presowing treatment of seeds is carried out by means of air-heat treatment for 3 -5 days and the etching of 80% TMTD, the care of crops is carried out by means of the main treatment at a plant height of 2-3 cm and additional treatment at a plant height of 3-12 cm with a mixture of tritium salts Penov acids and neutral components extracted from green fir tree, with the flow rate of the drug treatments at 50-150 mg / m, at a rate of fluid of 200-400 L / ha with the following ratios: acid: neutral components 5-10: 1.

A method of obtaining a biological product, called "VERVA", is environmentally friendly, affordable, cost-effective and is as follows.

By chemical nature and polarity, the main part of biologically active substances of green wood of conifers is represented by two groups: neutral and acidic. The composition of the neutral components includes terpenoids, essential oils, vitamins, etc. The composition of the acidic components is represented by fatty, di - and triterpenic acids. A necessary condition for the maximum possible extraction of acidic and neutral components from needles is the breaking of their connection with other compounds.

The method includes processing chopped wood green fir 0.5-20% aqueous solution of hydroxide or 1-20% aqueous solution of alkali metal carbonate in the ratio of raw materials: extractant 1: 5-12, followed by separation of the solid fraction.

In the process of extraction, the formation of water-soluble salts of tar and higher fatty acids contained in the needles of fir. Salts of resin acids are surfactants. Salts of higher fatty acids are micelle forming compounds. Micelles formed during processing solubilize, i.e. dissolve non-polar lipids of woody greens. In the process of processing, the needles are simultaneously saponified with an alkaline extractant and the neutral components are emulsified in a water-alkaline or water-carbonate solution of salts. Based on mass transfer processes, an oil-in-water emulsion is formed in the reaction suspension. At the end of the processing process, the emulsion is filtered. The resulting biological product is a dark brown liquid, easily diluted with water to the desired concentration. The relative density of the emulsion is 1.04-1.06 (20 ° C).

Example 1

Ground woody greens are treated with 2% sodium hydroxide solution. Receive 140 g of an emulsion containing 12 g / l sodium salt of acids and 2.4 g / l of neutral components.

Example 2

The milled woody greens are treated with a 5% sodium hydroxide solution. Receive 400 g of an emulsion containing 7 g / l sodium salt of acids and 0.7 g / l of neutral components.

Example 3

Ground wood greens are treated with 5% potassium hydroxide solution. Get 120 g of an emulsion containing 3 g / l of potassium salt of acids and 0.4 g / l of neutral components.

A method of growing flax flax is as follows.

The cultivation of flax flax was carried out over a layer of perennial herbs (clover). The stratum was initially treated with BDT-7 heavy disc harrows. The formation was raised in the third decade of August with PLN-5-35 plows with skimmers. As the weeds grew, the chaff was treated twice with a KPS-4 cultivator with cultivating paws on spring struts.

In early spring, the soil was buried with a B3TS-1 harrow to cover moisture. After that, cultivation was carried out by the cultivator KPSh-8 to a depth of 7-10 cm. Pre-sowing treatment was carried out with the combined RVK-5.4 aggregate. At the same time, equalizers were not used, since the previous treatments were performed quite qualitatively.

Before sowing, the seeds were subjected to air-heat treatment - heating for 3-5 days. For etching, 80% tetramethylthiuram disulfide (hereinafter TMTD) was used.

Sowing was carried out both on small plots with an area of 25 m ² , placed by the Latin square method with the number of repetitions of at least four, and in larger areas ranging in size from 0.6 to 1 ha. First class seeds were used. They started sowing when the soil at a depth of 10 cm was warmed up to 6-8 ° C (depending on where the samples were taken). Such sowing allows flax to be spread on the warmer days of August, when the activity of microflora, which provides the natural dewlobe, is highest. The application of the proposed method can further accelerate this process. The sowing rate was set by 23-25 million germinating seeds per 1 ha, which corresponds to the sowing rate of varieties resistant to lodging, since the inventive method improves the lodging resistance of even unstable varieties. Sowing was carried out with a SZL-3.6 linen seeder with a row spacing of 75 mm with a sowing depth of 1.8-2.2 cm.

To destroy the soil crust, seedlings were harrowed with a BSO-4 mesh harrow.

At a plant height of 2-3 cm, the first treatment with VERVA was carried out, for which a working solution was prepared, consisting of 50-150 mg / ha of the active substance. The second treatment with VERVA was carried out at a plant height of 6-10 cm in the same dose. In both cases, the rate of flow of the working fluid was set at 300 l / ha.

Harvesting was carried out manually on small plots and with a combine LK-4A with spreading on flax in large areas. The dewy lobe passed for 21-28 days, after which the trust was removed from the field and transferred to the flax mill.

The results of the experiments.

Production tests of the proposed method was carried out in the Novgorod and Tver regions in 2002-2003. in field experiments using randomized repetition.

The sowing interval of April 30-May 8 for field experiments and May 5-7 for vegetation.

Flax harvesting was carried out manually in small-plot experiments and in the combine harvester method in large areas during early yellow ripeness (60-70% of the total sown area) and into the stage of full ripeness.

For comparison, we present data on the use of well-known protective stimulant drugs produced by domestic and foreign industry and approved for use in the Russian Federation. Processing was carried out in recommended (generally accepted) doses for each drug (Tables 5, 6).

To determine resistance to drought, vegetation and field experiments were conducted on varieties Dashkovsky and Alexim (Table 1-4). The terms of sowing, processing and harvesting are similar to the above experiments.

In vegetative experiments, simulated conditions with high temperature (35-40 ° C) and without watering for 20 days after the phase of the "Christmas tree". The plants treated with the protective-stimulating complex were 15-20% higher than the control ones (without treatment with the protective-stimulating complex), the root system and the plants themselves were better developed.

To determine resistance to low temperatures, vegetative experiments were carried out in climatic chambers on varieties Dashkovsky and Alexim. Seeds were sown on April 30, seedlings appeared from May 4 to May 7.

In growing experiments at a height of 2-3 cm, flax plants were cooled for 12 hours to a temperature of (-3) - (- 5) ° С. As a result, 80% of the plants (of the number of seedlings) treated with a protective-stimulating complex continued normal growth and development and gave the planned yield. Among control plants (without treatment with a protective-stimulating complex), 35–40% continued to grow normally, while the rest died or were significantly stunted.

Thus, the studies confirm that the use of the claimed method of growing flax flax allows:

- increase the yield of flax straw;

- increase seed yield;

- increase the content of fibrous fractions;

- increase the resistance of plants to adverse factors - increase frost resistance, resistance of plants to drought and lodging, pests and diseases;

- speed up the process of dewlobes and increase the separability of the trust;

- improve the quality of flax fiber, in particular the parameters given in tables 2, 4;

- use low doses of the ingredients of the protective stimulating complex;

- eliminate the accumulation of the drug in plants.
