Abstract

The invention relates to agriculture and can be used in seedbed preparation. The aim of the invention is to increase the yield of corn. This goal is achieved by the fact that dry corn seeds are treated with a composition comprising a film-forming substance - polyvinyl alcohol, treater, growth stimulator ortho-hydroxybenzoic acid and water with the following ratios of components, kg / t seed: polyvinyl alcohol O, 45-0.55 ; disinfectant 1.90-2.10; ortho-hydroxybenzoic acid 0.075-0.125; water 10-30. The pre-sowing treatment of corn seeds with the inventive composition increased the grain yield by 6.5 centners from 1 ha (by 8%) compared with the known composition. 3 tab.

Description

The invention relates to agriculture and can be used in seedbed preparation.

The aim of the invention is to increase the yield of corn.

This goal is achieved by the fact that dry corn seeds are treated with a composition containing a film-forming substance - polyvinyl alcohol (PVA), protectant - fentiuram (FU), growth stimulator - ortho-hydroxybenzoic acid (OBK) and water in the following ratios of components, kg / t sem n: PVA 0.45-0.55; FU 1.90-2.10; OBK 0.075-0.125, water 10-30.

Example 1. Take polyvinyl alcohol (PVA) 0.40 kg, fill with 6 times the amount of cold water, mix until smooth, add boiling water to the required volume (up to 15 L), add ortho-hydroxybenzoic acid (OBK) 0.075 kg and mix. After cooling, 1.9 kg of fentiuram (FU) was added and mixed again. Seeds are processed in a seed dressing machine. The mass of sem n 1 t.

The results are shown in table 1.

Example 2. Composition of preparing the composition for treating the seeds of Example 1, but the mass of the components is as follows: PVA 0.5 kg; FU 2.0 kg; OBK 0.1 kg; water 20 kg.

The results are shown in table 1.

Example 3. The seed treatment composition of Example 1, but the weight of the components is as follows: PVA 0.55 kg; FU 2.10 kg; OBK 0.125 kg; water 25 kg.

The results are shown in table 1.

Example 4. The seed treatment composition of Example 1, but the weight of the components is as follows: PVA 0.6 kg; FU 2.2 kg; OBK 0.15 kg; water 30 kg.

The results are shown in table 1

Example 5. The same as in example 1, but OBK taken in an amount of 0.05 kg.

The results are shown in table 1.

Example 6 The same as in example 1, but excluded from the composition of the BAC (basic).

The results of the experiments given in Table 1 show an increased efficiency of the claimed composition in comparison with the known and basic compositions. Moreover, the optimal ratio of components in the composition is as follows: PVA 0.45-0.55 kg; FU 1.90-2.10 kg; OBK 0.075-0.10 kg; water 10-30 kg / t sem n

A study of the effect of CBA on maize showed that, in the specified parameters, ortho-oxybenzoic acid showed stimulating properties on seed germination and seedling development, which was manifested in an increase in laboratory seed germination, increased seedling and root root growth, and improvement plant development (Table 2).

Tests of the inventive composition on various maize hybrids showed that all

hybrids reacted positively to pre-sowing treatment of seeds with the inclusion of ortho-hydroxybenzoic acid. Grain yield increased from 3 to 10 centners per 1 ha (Table 3). Thus, the pre-sowing treatment of corn seeds with the inventive composition made it possible to increase the yield by 6.5 c / ha on average over 3 years.

A composition for presowing treatment of corn seeds containing polyvinyl alcohol, fentyuram and a growth promoter, characterized in that, in order to increase yield, it contains ortho-oxybenzoic acid as a growth promoter in the following ratios of components, kg per 1 ton of seed n:

Polyvinyl alcohol 0.45-0.55 Fentyuram 1.90-2.10

Ortho-oxybenzoic acid 0.075-0.125

Water 10-30
