Description

The invention relates to agriculture, in particular, to compositions for stimulating the growth and development of crops, improving their quality and productivity, and can be used for foliar feeding, as well as for presowing treatment of seeds. A known composition for stimulating the growth and development of crops, including cobalt and boron compounds, citric acid and alkanolamine and water (RF patent No. 2261600, IPC A01N 59/20, 2007). However, this composition is not effective enough.

A known composition for stimulating the growth and development of crops, including zinc compounds and copper compounds, citric acid and alkanolamine and water (RF patent No. 2229807, IPC A01N 59/20, 2004). However, this composition is not effective enough. Closest to the proposed invention is a composition for promoting the growth of crops, including alkanolamine, citric acid, zinc compounds, boric acid (RF patent No. 2261599, IPC A01N 59/20, 2007).

The objective of the present invention is to provide an effective composition for stimulating the growth and development of crops, and expanding the assortment due to the high selectivity of plants. The problem is solved in such a way that the composition for stimulating the growth and development of crops, including zinc compounds, citric and boric acid, alkanolamine and water, additionally contains copper compounds in a molar ratio in the mixture: zinc medical compound compounds: citric acid: boric acid: alkanolamine, equal to 1: (1-3) :( 1-50) (1:10) :( 4-100) in the following ratio of components, in wt.%:

A mixture of copper, zinc,

citric acid, boric acid and alkanolamine

in the molar ratio above 0.5-70 Water rest

To prepare the composition use:

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

Citric acid is used according to GOST 908-79.

As copper salts, copper sulfate (copper sulfate) is used in accordance with GOST 19347-84, or basic carbonate copper in accordance with GOST 5852-79, or copper citrate.

Zinc sulfate according to GOST 4174-77, zinc oxide according to GOST 10262-73 Boric acid according to GOST 18704-78 are used as zinc compounds.

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)

125 g of copper (II) sulfate pentahydrate, 41 g of zinc oxide, 31 g of boric acid, 105 g of citric acid, 298 g of triethanolamine and 485 g of water are mixed. The mixture is thoroughly mixed until a homogeneous solution is obtained. (The molar ratio of the active components Cu: Zn: boric acid: citric acid: TEA = 1: 1: 1: 1: 4).

Example No. 2.

12 g of copper sulfate pentahydrate (P), 43 g of zinc sulfate heptahydrate of zinc, 155 g of boric acid, 105 g of citric acid, 305 g of monoethanolamine and 560 g of water are mixed. (The molar ratio of active components of Cu: Zn: boric acid: citric acid: monoethanolamine = 1: 3: 50: 10: 100.)

Example No. 3.

11 g of copper (II) are mixed with basic carbon dioxide, 16 g of zinc oxide, 155 g of boric acid, 105 g of citric acid, 305 g of monoethanolamine and 381 g of water. (The molar ratio of the active components of Cu Selected acid: citric acid: monoethanolamine = 1: 2: 25: 5: 50).

Examples 4-5 are carried out analogously to example No. 1, changing the qualitative and quantitative ratio of the components. The component composition of the solutions are shown in table 1.

The resulting compositions are dark blue liquids with pH = 6-12 and are a concentrate of the fertilizer mixture.

Example No. 6 (prototype).

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

The test results are shown in table 2.

Analysis of the data presented in table 2 shows that the proposed composition is more effective compared to the prototype: it provides a higher overall yield of crops, and also allows you to expand the range of compounds to stimulate the growth and development of crops, which is necessary in connection with high selectivity of plants to the absorption of trace elements.
