Description

The invention relates to agriculture, can be used for fertilizing agricultural crops in the course of their growing season or using other preparations that stimulate the growth of plants, and is an improvement to the invention in the author. No. 1247340.

The purpose of the invention is to increase the duration of the action of plant-stimulating drugs.

PRI me R. In the preparation containing macro-, microelements, fungicide and growth substances, an adhesive was used as an adherent - a highly dispersed, chemically neutral silicon dioxide surface-active material obtained in a known manner in an amount of 10-20% by weight of the preparation.

Separate elements are included in the preparation in quantity, based on the requirements of a particular culture. Thus, flax plants per 1 centner of fiber carry out 5–8 kg of nitrogen.

1.5 -4 kg of phosphorus and 6-10 kg of potassium. Taking into account the percentage of assimilation of elements from mineral tukas, it is recommended to apply nitrogen, phosphorus, potassium in the ratio of 1: 2: 3 or 1: 3: 3 and 1: 3: 4. During the vegetation period, it is recommended to bring in 10–15 kg / ha of ammonium nitrate, urea, or nitrophoska along with vegetative plants together with herbicides. During the growing season, microelements become important, which contribute 0.5-0.7 kg / ha each.

A biostimulant torus (sodium humate) for vegetative plants is required within 100 g, a fungicide (boron) 150–200 g, kuprozan (foundationol) 150–300 g.

When developing the composition of the drug, it was assumed that during the growing season the plants are treated with an aqueous solution in an amount of 100-200 liters per hectare, which must contain a certain amount of adhesive, macronutrients, microelements, fungicide and biostimulant.

The amount of the aqueous solution is determined on the basis of the technological characteristics used for these purposes of the sprayers. At the same time, it was found that fine spraying with a flow rate of 50 l / ha is not acceptable, since applying a highly concentrated solution of chemicals to the extremely small surface area of the sheet does not have a positive effect on the growth and development of plants, but on the contrary gives a negative effect. The best results were obtained by spraying sowing at a solution rate of 100–200 l / ha. With a solution flow rate of 250-300 liters, part of it dripped from the leaves and the effect was low. This was also due to the fact that with a high consumption of water the concentration of the solution was also low.

With an optimal water consumption for preparing a solution of 100–200 l per 1 hectare of sowing, the necessary amount of adhesive — highly dispersed silicon dioxide — was determined. 0.5, 1.0, 1.5% solutions were prepared, and the plants were sprayed. The experiment showed good adhesion of a 1% solution, a 0.5% solution practically did not stick to the leaves, and a 1.5% concentration was almost unnecessary. Based on this, for the preparation of 100 l / ha of solution, 1 kg is needed, and for 200 l / ha, 2 kg of highly dispersed silicon dioxide. To determine the number of macroelements, microelements, fungicides and growth stimulants, vegetative experiments were carried out with the treatment of plants with solutions of different concentrations. The optimal concentration of trace elements in the solution was found to be 5-6%. A set of six components (Bo, Mo. Mn, C, Md, Zn) were used, taken in equal amounts.

Prepared 1, 0, 2.0, 3.0, 4.0% solutions, which in the composition of a 5% solution of macronutrients and 1% solution of highly dispersed silicon oxide at the rate of 100 l / ha were treated with flax plants in the phase of the Christmas tree. Here, the optimal concentrations were 2.0 and 3.0%, where yield increases were 14 and 17%. In the variant with the concentration of 1.0% of microelements, the yield increase was 12% (at the level of controp, without microelements), and in the variant with the concentration of 4.0% - 18%. Based on the results obtained, a trace element concentration of 2.0–3.0% was accepted.

The concentration of preparations: 1% of highly dispersed silicon oxide, 5% of macroelements and 1% of microelements were taken by us in the base solution, to which we added

Biostimulant - sodium humate to a concentration in a total solution of 0.06, 0.1, 0.2, 0.3, 0.4, 0.5%. In this experiment, the yield increase was 15, 18, 19, 21, 20, 21%. AT

therefore, optimal concentrations of 0.1–0.3% were assumed, where increases were significant.

In parallel with this, an experiment was conducted where plants in the herringbone phase were treated with a solution containing 1% highly dispersed silicon oxide and 0.1.0.2, 0.3, 0.4, 0.5% fungicide foundazol (cuprozan is possible). In all variants, flax plants were free from diseases, with a concentration of 12% in the control, where fungicide was not used. In this connection, a concentration of 0.2-0.4% is accepted.

Thus, for foliar feeding, plants are prepared for 1 hectare of sowing 1000 200 l of working solution with the concentration of preparations,%: highly dispersed silicon dioxide 1.0; macronutrients 5-6; trace elements 2.0-3.0; biostimulant torus 0.1-0.3; fungicide 0,2-0,4.

5 To prepare such a solution, 1-2 kg of highly dispersed silicon dioxide, 5-6 kg of macronutrients (1 kg of nitrogen, 2 kg of phosphorus and 2 kg of potassium), 2-3 kg of trace elements, 0.1-0.3 kg of biostimulant and

0 0.2-0.4 kg of fungicide.

Thus, the preparation for foliar feeding of flax plants is prepared from individual elements in wt.%: Macronutrients 50-60; trace elements 20-30; bio5 stimulator 1-3; fungicide 2-4; highly dispersed silicon dioxide 10-20.

8.5-11.7 kg per 100-200 liters of water are used per hectare.

0 As an example of a specific implementation, a composition with a content of 50% macronutrients (nitrogen 10%, phosphorus 20%, potassium 20%), 30% microelements (Mo 7.5, Mp 7.5, Zn 7.5, Mg 7.5 4% fungicide

5 (boron 2%, kuprozan 2%), sodium stimulator gumatate 2% and highly dispersed surface active silicon dioxide 13%, called Carpathians, which was tested and showed high efficiency on

0 crops of flax.

Tests were conducted on an area of 30 hectares, of which 10 hectares foliar dressing was not performed, 10 hectares foliar dressing in the phase, herringbirds were carried out by the preparation in an amount of 15 kg / hectare per 200 l of water, which included no adhesive (analog) and on 10 hectares, foliar top dressing was carried out with the preparation in the amount of 15 kg / ha, containing surface-active silicon dioxide. In the control (without foliar feeding, the yield of flax seed was 4.8 centners per hectare, flax fiber (in translation) 7.6 centners per hectare, the quality of flax straw was 1.50 numbered, in the second basic variant, on which extra foliar fertilization was carried out with the adhesive without adhesive was the yield of flax seed was 5.2 centners per hectare, flax fiber translated as 8 centners per hectare, the quality of flax straw was 1.50 in number, and in the variant where foliar feeding was carried out with a preparation containing surface-active highly dispersed silicon dioxide - seed yield 6.3 centner / ha and flax fiber (in translation) 9.0 centner / ha, flax straw quality 1.50 n pa.

 At the same time, observations visually and under a microscope, as well as chemical analyzes, showed that in the variant where the preparation containing the surface-active highly dispersed silicon dioxide, macro- and microelements was used, the biostimulant on flax leaves and stalks was kept for 18 21 days, i.e. almost throughout the entire phase of rapid growth, whereas in the variant with foliar feeding with the preparation without adhesive, after the first day only traces of .macro and microelements were found on the leaves and stalks of the plants,

The preparation for foliar feeding was also tested on sugar beet crops, where it confirmed its high efficiency.

KPC glue, dextrin, polyvinyl alcohol, polyvinyl acetate, silica gel, and an adhesive were tested as a adhesive. The surface-active compound was chemically neutron. Radial silicon dioxide. However, from the listed glue, CMC and dextrin in the studied concentrations of 0.5-1.5% had a weak holding capacity, and polyvinyl alcohol, polyvinyl acetate and silica gel exerted a negative effect on the surface of the leaves, which showed yellowing.

The use of surfactant chemically neutral silica was acceptable — it had no side effects, apparently due to the fact that it is neutral and has good retention at 1% concentration. In this connection, all experiments on the development of the composition of the preparation were carried out with an adhesive, a substance that was used for a new purpose in a certain amount.
