Description

The invention relates to agriculture and can be used for the cultivation of vegetable nightshade crops.

A technical solution is known (see RF patent No. 2178246, class A01C 1/00, 2002), where plant growth regulators - furolan and Krasnodar-1 in a ratio of 5: 1 are used together to increase yield and quality of crops.

A disadvantage of the known technical solution is the low percentage of inclusion in the composition of the drug "Krasnodar-1" - 16.5% by weight. Given that in nightshade crops, Krasnodar-1 is the most effective among growth regulators, it is used to a limited extent due to the low percentage. This is manifested in a shortage of gross harvests of nightshade crops and a decrease in the output of marketable products of higher quality.

Also known is a method of treating seeds of vegetable crops (see RF patent No. 2133586, class A01C 1/00, 1999 - prototype), including presowing treatment of seeds with an aqueous solution of a complex preparation.

The disadvantages of the known technical solutions are the ineffective effect on nightshade crops and use only for root crops.

The technical solution to the problem is to increase productivity and greening agricultural production.

The problem is achieved in that in a method of growing vegetable nightshade crops, including pre-sowing seed treatment with an aqueous solution of a complex preparation according to the invention, as a complex preparation, a mixture of physiologically active substances furolan and Krasnodar-1 is used in a weight ratio of 4: 1 components and the seeds are kept in an aqueous solution of the drug with a concentration of 0.001-0.01% for an hour, followed by a hectare consumption rate of the drug for tomatoes 0.35-0.4 g / ha, sweet pepper 0.2-0.3 g / ha and for eggplant 0.08-0.12 g / ha.

The novelty of the proposed proposal is due to the fact that through the use of an aqueous solution of a complex preparation consisting of growth regulators having active substances from the class of furan acetals - furolan and Krasnodar-1 for processing seeds of nightshade crops, the yield of high-quality marketable products of such vegetables increases like tomatoes, peppers and eggplant. In addition, the consumption of both furolan and Krasnodar-1 preparations is reduced by 1 ha, because triple treatment of plants is excluded when it is replaced by treatment of seeds, as a result of which there is no environmental pollution characteristic of the treatment of vegetative plants.

According to the scientific, technical and patent literature not found, similar to the claimed, a set of features, allowing to obtain a technical result that was previously not achieved by known means. This allows you to judge the inventive step of the proposed proposal.

The proposed method of presowing processing of nightshade crops meets the criterion of "industrial applicability", because it is reproducible, simple to implement and affordable.

Growth regulators from the class of furan acetals - furolan and Krasnodar-1, have all toxicological and hygienic characteristics and are included in the list of plant growth regulators approved for use in agriculture (Handbook of pesticides and agrochemicals approved for use in the Russian Federation. M: Agrorus, 2004 - p. 248). The complex preparation used: a mixture of physiologically active substances of furolan and the Krasnodar-1 regulator, taken in the ratio of components 4: 1, has the working name “katribgon”.

An example of a specific implementation of the method of presowing treatment of vegetable nightshade crops.

Before germination, the seeds were soaked in solutions of furolan (0.05%), Krasnodar-1 preparation (0.002%) and katribgon (0.001, 0.005, 0.01, 0.05, 0.1), and in water, the control variant. Germination energy and seed germination were determined in laboratory conditions in Petri dishes, a bed for seeds - filter paper, within the time periods specified in GOST 12038-66. Exposure to seed treatment - 1 hour.

Field experience. Vegetation site of the Department of Plant Physiology and Biochemistry KGAU. The accounting area of the plots is 25 m ² . The repetition of the experiments is 4 times.

Scheme of experience:

1) control - sowing seeds soaked in water;

2) “Krasnodar-1” - sowing with seeds soaked in a 0.002% solution of “Krasnodar-1” in water;

3) furolan - sowing with seeds soaked in a 0.05% solution of furolan in water;

4) composition - sowing with seeds soaked in an aqueous solution of a mixture of preparations of furolan and Krasnodar-1 in a ratio of 5: 1;

5) katribgon - sowing with seeds soaked in a 0.01% solution of katribgon (optimal concentration established on the basis of laboratory experiment data).

Seeding rate: for tomatoes - 2 kg / ha, for pepper - 1-1.5 kg / ha, eggplant - 0.4-0.6 kg / ha. The consumption rate of the solution is 2 liters per 1 kg of seeds. Seeding depth - 2-3 cm.

Sowing scheme: for tomatoes - 50 × 75 cm, for pepper - 50 × 70 cm, for eggplant - 50 × 70 cm. 5 pcs were sown in each well. seeds treated in water (control) and in solutions of the tested drugs (experimental options). In the seedling phase, thinning was carried out, leaving 2 plants (typical) in the hole.

The invention is illustrated by the following examples of the proposed method for pre-sowing seed treatment of nightshade crops, conducted in laboratory and field experiments.

Example 1. Tomatoes.

From the data table. Figure 1 shows that the treatment of tomato seeds before sowing with the tested growth regulators increases the germination energy (64-71%, against 60% in the control) and germination (73-80%, against 68% in the control), stimulates the intensity of germination. At the same time, the effect of katribgon on seed germination is higher than their separate application. In terms of the totality of the considered indicators, the most effective was seed treatment with a 0.01% solution of katribgon. In this version, the absolute values of the considered indicators are maximum (germination energy - 74%, germination - 85%, root length - 5.7 cm, sprout - 6.4 cm, raw weight of the root - 1.41 g / 100 pcs., Sprout - 1.79 g, dry weight of the root - 0.14 g / 100 pcs., Sprout - 0.17 g; against - 60 and 68% in the control, 69 and 78% in the composition, 4.3 and 4.7 cm in control, 5.2 and 6.1 cm in the composition; 0.85 and 1.27 g, 0.08 and 0.11 g / 100 pcs. in the control and 1.29, 1.58, and 0.13, 0.15 g / 100 pcs respectively). Thus, the optimal concentration when processing tomato seeds before sowing with Katribgon is 0.01%.

The analysis presented in table. 2 data indicates the fact that pre-sowing treatment of tomato seeds with the tested drugs enhances growth processes. In all experimental variants, higher and leafy plants were formed, with the highest indicators of leaf surface, biomass and dry matter mass of aboveground organs. Moreover, in the variant with katribgon, the absolute values of the considered growth parameters were maximum (height - 70.0 cm, number of leaves - 22.5 pcs., Leaf area - 52.8 cm ² , biomass of aboveground organs - 126.81 g, dry weight substances - 24.98 g / plant; in the control, respectively - 64.6 cm, 17.2 pcs., 45.4 cm ² , 116.27 and 20.00 g).

Presented in the table. 3 data indicate the fact that the maximum yield was obtained with the use of katribgona - 266.4 c / ha (in the control - 229.7 c / ha). Obviously, with the use of furolan and Krasnodar-1 preparations, synergism is manifested in the composition, and when applied separately, the effect on growth and morphogenesis is less pronounced.

The yield of tomatoes in the experimental versions, especially in the variant with katribgon, increases due to the formation of larger ones (fruit diameter - 5.7-6.2 cm, in the control - 5.4 cm) and weight (80.1-95, 7 g, 64.0 g - in control) of the fruit.

From the table. Figure 4 shows that all tested drugs improve the quality of tomato fruits. The highest quality fruits were obtained in the variant with katribgon (sugar content - 2.20%, vitamin C - 13.3 mg%, dry matter - 5.18%; in the control - 1.73%, 10.2 mg%, 5, 01% respectively).

Thus, possessing the property of synergism, the preparation katribgon (a solution of the drug Krasnodar-1 in furolan) is more than separate use of the drugs, enhances the growth and shaping processes of tomato plants and increases the yield and quality of fruits.

Example 2. Eggplant.

Presented in the table. 5, the data indicate the fact that the treatment of eggplant seeds before sowing with Katribgon to a greater extent than the separate use of the components of the composition increases the sowing quality of seeds. The highest values of the considered indicators were noted during seed treatment with 0.01% katribgon solution (germination energy - 62.0%, germination - 70.5%, root length - 2.2 cm, sprout - 3.3 cm, raw weight of roots - 1.14 g, sprouts - 1.56 g / 100 seedlings, dry weight - 0.15 and 0.18 g / 100 seedlings, against - 49.5%, 58.5%, 1.7 cm, 2.2 cm, 0.68 g, 0.84 g, 0.09 g, 0.10 g / 100 seedlings in the control and 54.8, 68.5%, 2.0 and 3.0 cm, 1.01 and 1 , 39 g, 0.13 and 0.17 g / 100 seedlings in the composition, respectively). Therefore, the optimal concentration of katribgona when processing eggplant seeds before sowing is 0.01%.

As can be seen from the data table. 6, the treatment of eggplant seeds with the tested preparations enhances the growth of plants in height, the growth of biomass and the accumulation of dry matter by aboveground organs (plant height - 46.2-51.5 cm, in the control - 45.6 cm, biomass - 81.74-87, 25 g, dry weight - 16.35-17.40 g, in the control - 15.82 g). In all experimental variants, the leaf surface increases (5.4-7.0 dm ² , in the control - 4.8 dm ² ) due to the formation of a larger number of leaves (17.1-21.3 pcs., In the control - 14.5 PC.). The most active growth processes occur during seed treatment with a 0.01% solution of katribgona.

Data analysis table. 7 shows that when treating eggplant seeds before sowing with test drugs, their productivity increased significantly (by 6.8-18.2%). The highest increase (18.2%) was obtained by seed treatment with a 0.01% solution of Katribgon.

The increase in yield occurs due to the formation of larger ones (diameter - 5.2-7.0, in the control - 4.6 cm, length of the fruit - 9.1-10.9 cm, in the control - 8.5 cm) and weight (90.1-114.2 g, in the control - 85.4 g) of fruits.

The data table. 8 indicate the fact that the tested drugs improve the quality of the fruit - the content of sugar (2.6-2.9%, versus 2.4% in the control) and vitamin C (4.3-5.0% mg) increase in the fruit / 100 g of crude substance, in the control - 4.1% mg). Fruits with high sugar content and vitamin C content were obtained in the embodiment using the drug Katribgon (0.01% solution).

Thus, of all the tested drugs, the most effective was the drug Katribgon.

Example 3. Sweet pepper (Bulgarian).

From the data table. Figure 9 shows that the treatment of pepper seeds with growth regulators significantly enhances the process of seed germination. Moreover, in terms of the intensity of the effect on this process, the mixture of drugs (katribgon) turned out to be more effective than the use of its components (furolan and Krasnodar-1) in its pure form. The highest values considered in the table. 9 indicators were obtained during seed treatment with 0.01% katribgon solution (germination energy - 70.0%, germination - 74.6%, root length - 3.3 cm, sprout length - 2.8 cm; in the control - 57.6 %, 60%, 1.9 and 1.9 cm, respectively). The most active was the accumulation of biomass of roots and sprouts (1.35 and 2.10 g / 100 seedlings, in the control - 1.05 and 1.30 g) and dry matter mass (0.20 and 0.23 g, in the control - 90.112 and 0.17 g) when using katribgona.

Presented in the table. 10 data indicate the fact that the treatment of sweet pepper seeds with a mixture of tested drugs (furolan and Krasnodar-1 - katribgon in the optimal concentration (0.01%)) enhances plant growth to a greater extent than their separate use. The maximum values of all considered growth indicators were noted in the variant with katribgon (height - 52.2 cm, number of leaves - 37.1 pcs., Leaf area - 7.3 dm ² , wet weight of aboveground organs - 60.94 g, dry - 16 , 08 g; in the control - 45.7 cm, 28.4 pcs., 4.8 dm ² , 52.42 and 11.53 g, respectively).

The increase in the intensity of seed germination and plant growth with the use of test drugs, especially katribgona, contributed to the formation of larger fruits. The largest fruits in size and weight (Table 11) were obtained in the embodiment using katribgon (fruit diameter - 4.5 cm, its length - 8.3 cm and weight - 44.178 g; in the control, respectively - 3.3 cm, 6 8 cm and 25.86 g). The formation of a larger number and larger fruits led to an increase in pepper productivity.

The treatment of pepper seeds with furolan and the Krasnodar-1 preparation, separately and in the composition, significantly increased its yield (Table 12). The increase amounted to about 7.7-26.4% for the experimental variants. The highest yield (244.3 c / ha, in the control - 193.2 c / ha, HCP ₀₅ -9.9 c / ha) was obtained with the use of the drug Katribgon. Of the starting preparations on pepper, the Krasnodar-1 preparation turned out to be more effective (yield increase - 20.4%, in the variant with furolan - 7.7%).

The quality of fruits of sweet pepper is characterized by the content of dry matter, vitamin C and sugar in them.

As can be seen from the data table. 13, in all experimental variants, better fruits were formed than in the control (water) in terms of quality, with a higher content of sugar and vitamin C, as well as dry matter. Higher values of the considered indicators are noted in the variant with katribgon.

Thus, the use of furolan and Krasnodar-1 preparations on vegetable crops (tomatoes, peppers, eggplants) separately or jointly in the form of their composition, called katribgon, is highly effective. In addition, the use of katribgon and the use of drugs that make up the composition, in relation to control is more economical.

The high efficiency of the use of the drug Katribgon on vegetable (nightshade) crops - tomatoes, peppers and eggplant - requires a widespread introduction of the developed technique.

The applied formulation for Krasnodar-1, an ethanol solution of the active substance, creates inconvenience in agricultural production, since before use it is necessary to dissolve the drug in ethanol, which limits its use. To eliminate this drawback, a new water-soluble agent (katribgon) was developed, consisting of a solution of Krasnodar-1 in furolan in a certain ratio. Katribgon based on furolan and Krasnodar-1 plant growth regulators approved for use in the Russian Federation is effective with the lowest consumption rate per hectare of those currently used in agriculture, which suggests its promising role as a growth regulator in nightshade crops (see table. 14).

When treating tomato seeds before sowing with growth regulators, productivity increased by 20.5 c / ha (8.9% - water control) from the use of Krasnodar-1, by 18.2 c / ha (7.9%) from application the drug furolan and at 46.7 kg / ha (20% - control water) and 23.3 kg / ha (9% - control composition according to the prototype) from the use of the drug katribgon. To a greater extent, the use of a mixture of regulators increased the quality of the fruit (increased content of dry matter and sugar, vitamin C). The drug katribgon showed a stronger effect on the growth, development, productivity and quality of sweet pepper and eggplant than the separate use of drugs. When using the drug Katribgon on eggplant, the yield increased by 18.2% (control water) and 3% (control prototype), furolan preparations - 6.8%, Krasnodar-1 - 13.4%, fruit weight was 114 , 2 g (against the control of furolan 90.1 g and Krasnodar-1 "105.0 g), sugar content - 2.9% (against the control of furolan 2.6 and Krasnodar-1" 2.8%) and an increase in sugar content 1.2 times (control - water) the content of vitamin C is 5.0% mg / 100 g of crude material (against control of furalan 4.3 and Krasnodar-1 4.7%) and 1.21 times (control - water).

When using the drug Katribgon on sweet pepper, productivity increased by 26.4% (control water) and 4% (control prototype), furolan - by 7.7%, Krasnodar-1 - by 20.4%; fruit quality improved (dry matter content amounted to 11.0% when using Katribgon, 10.4% to Furolan, 10.5% to Krasnodar-1, sugar content to 5.2, 4.3 and 4.8% , the content of vitamin C 125.8, 124.7, 125.3 mg%, respectively). At the same time, the consumption of both furolan and the Krasnodar-1 growth regulator per 1 hectare is significantly reduced: triple treatment of plants is excluded when it is replaced by processing of seed, thereby significantly reducing the cost of introducing the regulator. In this case, there is no environmental pollution characteristic of the processing of vegetative plants.
