Composition for stimulating growth and development of crops

 

Composition for stimulating growth and development of crops in the following ratio, wt.%: monoethanolamine, or diethanolamine, or triethanolamine, or dimethylethanolamine 2,0-30,0, cobalt sulphate or cobalt acetate or cobalt chloride or cobalt carbonate basic 0,001-25,0, citric acid, and/or copper sulfate or copper acetate, or copper hydroxide or copper carbonate basic, or copper chloride, or copper citrate 0,001-25,0, water the rest. The technical result is to create a highly effective composition for stimulating growth and development of crops that increase the gluten content in grain crops. table 2.

The invention relates to agriculture, in particular, compositions for stimulating the growth and development of crops, improving quality and yield, and can be used for foliar feeding, as well as for presowing treatment of seeds.

Known composition for stimulating growth and development of crops, including monoethanolamine, boric acid, copper sulphate and water (patent 2086126, IPC A 01 N 31/08, 1997). Known castelmur, includes copper chloride or copper bromide or copper hydroxide, or hydroxycarbonate copper, or copper nitrate or copper acetate, boric acid or its mixture with the alkali, or sodium tetraborate or potassium tetraborate, alkanolamine and water (patent RF 2143198, IPC A 01 N 59/20, 1999). However, the composition is not sufficiently effective.

Closest to the proposed invention is a composition for stimulating the growth of agricultural crops, including alkanolamine, salt of copper, molybdenum acid or a salt thereof, or a mixture of lye and water (patent RF 2162285, IPC A 01 N 31/08, 2001). The composition is insufficient and does not allow to achieve high content of gluten in grain crops.

The present invention is highly effective composition for stimulating growth and development of crops, the raising of the gluten content in grain crops and the expansion of the range of compositions due to the high selectivity of the plants.

The problem is solved so that the composition for stimulating growth and development of crops, including alkanolamine and water, as alkanolamine contains monoethanolamine, or diethanolamine, or triethanolamine main, or citric acid, and/or copper sulfate or copper acetate, or copper hydroxide or copper carbonate basic, or copper chloride, or copper citrate in the following ratio, wt.%: Monoethanolamine, or diethanolamine, or triethanolamine, or dimethylethanolamine - 2.0 to 30.0 cobalt Sulfate or cobalt acetate or cobalt chloride or cobalt carbonate basic - 0,001-25,0 Citric acid, and/or copper sulfate or copper acetate, or copper hydroxide or copper carbonate basic, or copper chloride, or copper citrate - 0,001-25,0 Water - the Rest For the preparation of a composition using known chemical substances: monoethanolamine (IEA) TU 6-09-2447-90 or THE 602-915-84, or diethanolamine (deja) TU 6-09-2652-91, or triethanolamine (tea) TU 6-02-916-79, or dimethylethanolamine (DMEA) TU 6-02-1986-91.

As copper compounds can be used, for example: copper sulfate CuSO45H2O according to GOST 19347-84, or copper acetate according to GOST 5852-79, or copper carbonate basic GOST 8927-79, or copper chloride CuCl22H2O according to GOST 4167-74, or copper citrate, or hydroxide of copper.

As compounds of cobalt can be used in the p>

Citric acid is used according to GOST 908-79.

The proposed composition is produced by mixing the starting components in the specified proportions. Cited specific examples of formulation.

Example 1 (proposed).

Mix of 48.5 g of water, 14 g of cobalt sulfate, 10 g of citric acid, 12.5 g of copper sulfate and 15.0 g of monoethanolamine. The mixture was thoroughly stirred to obtain a homogeneous product.

Examples 2-11 carried out analogously to example 1, changing the qualitative and the quantitative ratio of the components. The composition of the obtained compounds are shown in table 1.

Example 12 (prototype).

Example 13.

To 85,5 g of water, add 3 g of cobalt sulfate and then to 112.5 g of copper sulfate. The mixture was thoroughly stirred to obtain a homogeneous product.

Example 14.

To 75 g of water, add 15 g of monoethanolamine, 10 g of citric acid and the mixture was thoroughly stirred to obtain a homogeneous product.

The resulting composition is a clear liquid dark purple color with density of 1,100-1,200 kg/DM3pH 9-11.

The proposed structure of experience as a growth promoter for presowing seed treatment and foliar nutrition of plants.

1. Pre-treatment ("the required amount of composition according to the scheme experience below, is mixed with water (total solution volume of 15 liters). The fluid flow 15 l/tonne of seed. Seed treatment is conducted for 3 days before sowing.

2. Foliar treatment of plants carried out by spraying with a solution, which is obtained by mixing 0.5 l of the composition in 100 l of water. On 1 ha of sown area spend 250 l of this solution. Foliar spraying of crops is carried out before going into winter - 1 late October and early resumption of vegetation - 3rd decade of April. The flow tank liquid was 250 l/t, the concentration of working - 1,2%.

Field experiments to identify the effectiveness of the compounds was carried out in the farms of the Republic of Tatarstan.

The soil is leached clayey soil (humus content of 6.5%, available phosphorus and exchangeable potassium - 115 and 127 mg/kg soil, respectively, (pH of soil extract - acid) and grey forest medium (humus - 3,4%), available phosphorus and exchangeable potassium - 272,5 and 140 mg/kg of soil, pH of soil extract - srednekislye).

Soil low provided the trace elements copper and cobalt.

When conducting assessments and observations using the Method of the state of crops testing", 1987

Studies conducted on the background of make full who of itani samples of the composition shown in table 2.

Analysis of the data presented in tables 1 and 2 shows that the proposed formulation is more effective in comparison with prototype: it provides high yield of crops for both preplant and foliar treatment of plants allows to increase the gluten content in grain crops and to expand the range of compositions for stimulating the growth and development of crops, which is necessary due to the high selectivity of the plants.
