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 feeding, as well as for pre-sowing seed treatment. 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 alkanolamine, citric acid, zinc compounds, boric acid (RF patent No. 2261599, IPC A01N 59/20, 2007).

However, this composition is not effective enough.

Closest to the proposed invention is a composition for stimulating the growth of crops, including zinc compounds and copper compounds, citric acid and alkanolamine and water (RF patent No. 2229807, IPC A01N 59/20, 2004). 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 so that the composition to stimulate the growth and development of crops, including molybdenum, zinc, citric acid, alkanolamine and water compounds, additionally contains copper compounds in a molar ratio in the mixture: molybdenum compounds: copper compounds: zinc compounds: citric acid: alkanolamine equal to 1: (1-10) :( 1-25) :( 1: 100) :( 4-100) in the following ratio of components, wt.%:

A mixture of compounds of molybdenum, copper, zinc, citric 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 TU 6-09-01-228-84.

As zinc compounds, zinc sulfate is used in accordance with GOST 4174-77, zinc oxide is in accordance with GOST 10262-73

Molybdenum compounds: ammonium molybdenum acid according to GOST 3765-72, molybdenum acid TU 6-09-2154-77.

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, 96 g of molybdenum acid ammonium, 105 g of citric acid, 298 g of triethanolamine and 335 g of water are mixed. The mixture is thoroughly mixed until a homogeneous solution is obtained. (The molar ratio of the active components of Cu: Zn: Mo: citric acid: TEA = 1: 1: 1: 1: 4).

Example No. 2

Mix 25 g of copper (II) sulfate pentahydrate, 72 g of zinc sulfate heptahydrate, 1.92 g of molybdenum acid ammonium, 210 g of citric acid, 250 g of monoethanolamine and 441 g of water. (The molar ratio of the active components of Mo: Cu: Zn: citric acid: monoethanolamine = 1: 10: 25: 100: 400).

Example No. 3

11.1 g of copper (II) is mixed with basic carbon dioxide, 20.25 g of zinc oxide, 8.1 g of molybdenum acid, 52.5 g of citric acid, 152 g of monoethanolamine and 756 g of water. (The molar ratio of the active components of Mo: Cu: Zn: citric acid: monoethanolamine = 1: 2: 5: 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 a pH of 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.

The 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.
