Description

The invention relates to agriculture, in particular to compositions for stimulating the growth and development of crops, increasing their quality and productivity, and can be used for foliar top dressing, as well as for presowing seed treatment.

A known composition for stimulating the growth and development of crops based on ethanolamine (ed. Certificate. No. 852302, IPC A 01 N 33/04, 1981). Known composition is not effective enough.

A known composition for stimulating the growth of crops, including copper chloride or copper bromide, or copper hydroxide, or copper hydroxycarbonate, or copper nitrate, or copper acetate, boric acid or its mixture with alkali or sodium tetraborate, or potassium tetraborate, alkanolamine and water ( RF patent No. 2143198, IPC A 01 N 59/20, 1999). However, this composition is not effective enough.

Closest to the proposed invention is a composition for stimulating the growth of crops, including monoethanolamine, boric acid, copper sulfate and water (patent No. 2086126, IPC A 01 N 59/20, 1997). The specified composition is not effective enough.

The objective of the present invention is to provide a highly effective composition for stimulating the growth and development of crops and expanding the range of compositions due to the high selectivity of plants.

The problem is solved so that the composition to stimulate the growth and development of crops, including alkanolamine, boric acid and water, as alkanolamine contains monoethanolamine and / or diethanolamine and / or triethanolamine and additionally contains citric acid and cobalt sulfate or cobalt chloride, or cobalt carbonate, or cobalt acetate, or cobalt citrate in the following ratio of components, wt.%:

Monoethanolamine and / or diethanolamine and / or triethanolamine 5-35 Boric acid 1-25 Lemon acid 5-35 Cobalt sulfate or cobalt chloride, or cobalt carbonate, or cobalt acetate or cobalt citrate 1-20 Water rest

To prepare the composition use:

- Monoethanolamine (MEA) according to TU 6-09-2447-90 or TU 602-915-84 or diethanolamine (DEA) according to TU 6-09-2652-91, or triethanolamine (TEA) according to TU 6-02-916- 79, or dimethylethanolamine (DMEA) according to TU 6-02-1986-91;

- Boric acid according to GOST 18704 - 78.

- Citric acid is used according to GOST 908-79.

As cobalt salts, for example, cobalt sulfate or carbonic cobalt, or cobalt chloride (“Brief Chemical Reference”, publishing house “Chemistry”, Leningrad Branch, 1978, pp. 73-74), or acetic acid cobalt can be used ( Chemical Encyclopedia, Moscow: Publishing House "Soviet Encyclopedia", 1990, v.2, p.822).

The proposed composition is obtained by mixing the starting components in the indicated proportions. We give specific examples of the preparation of compositions.

Example No. 1 (proposed).

Mix 1 g of cobalt citric acid, 34 g of water, 5 g of citric acid, 25 g of boric acid and 35 g of monoethanolamine. The mixture is thoroughly mixed until a homogeneous product.

Examples No. 2-No. 7 carry out analogously to example No. 1, changing the qualitative and quantitative ratio of the components. The component composition of the obtained compositions are shown in table 1.

The resulting compositions are transparent dark purple liquids with a pH of 9-11.

Example No. 8 (prototype).

We present the test data of the proposed composition for pre-sowing seed treatment and foliar feeding of plants.

1. Pre-sowing treatment ("Instructions for seed dressing", approved on 01.10.1986 by the Gosagroprom of the Russian Federation).

To process 1 ton of seeds, the required volume of the composition is mixed with water according to the experimental scheme below (total solution volume of 15 l). The flow rate of the working fluid is 15 l / t of seeds. Seed treatment is carried out 3 days before sowing. The test results are shown in table 2.

2. Foliar treatment of plants is carried out by spraying with a solution, which is obtained by mixing 0.2 l of the composition in 100 l of water. On 1 ha of sown area, 200 l of the finished solution are consumed. Non-root spraying of crops is carried out before leaving for the winter - 1 decade of October and at the beginning of the resumption of vegetation - 3 decade of April.

Field experiments to determine the effectiveness of the compositions are carried out on the farms of the Republic of Tatarstan.

Characteristics of the soil used in testing the composition: leached clay chernozem (humus content of 6.5%, mobile phosphorus and exchange potassium 115 and 127 mg / kg of soil, respectively, pH of the salt extract is medium acid) and gray forest medium loam (humus - 3.4% , mobile phosphorus and exchange potassium 272.5 and 140 mg / kg of soil, pH of the salt extract is medium acid).

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

Studies are carried out against the background of mineral fertilizers at the rate of N ₁₂₀ P ₇₀ K ₁₀₀ . Agricultural technology is traditional. The test results of the samples of the composition are shown in tables 2 and 3.

Analysis of the data presented in tables 2 and 3 shows that the proposed composition is more effective compared to the prototype: it provides high crop yields, both in pre-sowing and foliar treatment of plants, allows you to expand the range of compounds to stimulate growth and development crops, which is necessary due to the high selectivity of plants.
