Abstract

The invention relates to agriculture and can be used for pre-sowing treatment of seeds of agricultural crops. The purpose of the invention is to increase the productivity of plants. The goal is achieved by the fact that before sowing the seeds are treated with a composition comprising polyvinyl alcohol, a binder and water, which contains wheat flour as a binder in the following ratio of components, wt%: polyvinyl alcohol 3-3.5; wheat flour 6-7; water the rest. 3 tab.

Description

The invention relates to agriculture and can be used for pre-sowing treatment of seeds of agricultural crops.

The purpose of the invention is to increase the productivity of plants.

The goal is achieved by the fact that before sowing the seeds are treated with a composition containing polyvinyl alcohol (PVA), an adhesive, which is used as wheat flour, and water in the following ratio, wt.%:

PVS3.0-3.5

Wheat flour 6,0-7,0

WaterEverything

Example. The composition is prepared as follows. 0.30, -0.35 kg PVA is dissolved in 8 l of water, heated to 80-85 ° C. Then, with constant stirring, a suspension of flour is prepared by adding 0.6-0.7 kg of it to 2 liters of water with a temperature of 25-30 ° C. The flour suspension is added to the PVA solution cooled to 25-30 ° C. The resulting mixture is stirred for 2-3 minutes.

The proposed composition is used on corn seeds (Moldavsk variety 237). wheat (variety Omsk 9) and barley (variety Donetsk 8). For comparison, a known formulation consisting of PVA (3 wt.%), Starch (6 wt.%) And water (the rest) is used. As a control, use seeds without treatment.

Seeds are poured on the asphalt site, treated with the composition, thoroughly mixed every 23 hours and after 2 days they are sown in the soil.

Test options are as follows: 1 - control (without treatment); 2 - PVA 3 wt.%, Flour 6 wt.%, Water the rest; 3 - PVA 2 wt.%, Flour 5 wt.%, Water the rest;

4- PVA 3 wt.%, Starch 6 wt.%, Water the rest.

For 100 kg of seeds, 20 liters of the proposed composition is required.

Table 1 shows the results of the influence of additives on the rheological properties of PVA; Table 2 shows the effect of the proposed composition on the productivity of maize; in table 3 - on the productivity of wheat and barley.

As can be seen from the presented results, replacing starch in the known composition for coating seeds with flour accelerates the formation of a film and increases its strength (Table 1). The resulting film on the surface of seeds protects them from the adverse effects of low temperatures and the harmful effects of microflora. and also has a stimulating effect, which leads to an increase in plant productivity (Table 2 and 3).
