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 of crops, including alkanolamine, citric acid, zinc and / or copper compounds and water (RF patent No. 2229807, IPC A01N 59/20, 2004). However, this composition is not effective enough.

A known composition for stimulating the growth of crops, including molybdenum compounds, copper compounds, alkanolamine, citric acid and water (RF patent No. 2303873, IPC A01N 59/20, 2007). This composition is not effective enough.

Closest to the proposed invention is a composition for stimulating the growth of crops, including alkanolamine, boric acid, citric acid, cobalt compounds and water (RF patent No. 2261600, IPC A01N, 2005). However, this 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 in such a way that the composition for stimulating the growth and development of crops, including alkanolamine, boric acid, citric acid and water, additionally contains a manganese compound selected from manganese sulfate, basic manganese carbonate, manganese chloride, and as alkanolamine it contains monoethanolamine or diethanolamine or triethanolamine with a molar ratio in the mixture: manganese compound: boric acid: citric acid: alkanolamine equal to 1: (1-8) :( 1-10) :( 4-30) and in the following ratio components, wt.%:

A mixture of a compound of manganese, boric acid, citric acid and alkanolamine in molar ratio above 0.5-65 Water rest

To prepare the composition use:

- Monoethanolamine (MEA) according to TU 6-09-2447-90, or according to 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.

Boric acid - according to GOST 18704-78.

As manganese compounds, manganese sulfate, or basic manganese carbonate, or manganese chloride are used (Brief Chemical Reference Book, Leningrad, 1991, p. 83).

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

Example 1 (proposed).

Mix 13.8 manganese sulfate, 10.5 g of citric acid in 39 g of water. 6.2 g of boric acid and 30 g of triethanolamine are added to this mixture with stirring. The mixture is thoroughly mixed until a homogeneous product is obtained (The molar ratio of active ingredients Mn: boric acid: citric acid: triethanolamine is 1: 2: 1: 4.)

Example 2

39.8 g of water, 5.1 g, basic manganese carbonate, 3.1 g of boric acid, 3.1 g of citric acid, 31 g of monoethanolamine are mixed (Molar ratio of active ingredients Mn: boric acid: citric acid: MEA = 1: 1: 2: 10.)

Example 3

1.98 g of manganese chloride, 4.96 g of boric acid, 21 g of citric acid, 12.2 g of monoethanolamine and 55, 46 g of water are mixed. (The molar ratio of the active components of Mn: boric acid: citric acid: MEA = 1: 8: 10: 30.)

Examples 4-6 are carried out analogously to example 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 light brown liquids with pH 8-12 and are a concentrate of the fertilizer mixture.

Example 7 (prototype).

We present the test data of the proposed composition for foliar plant nutrition.

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. 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 in the winter of -1 decade of October and at the beginning of the resumption of vegetation - 3 decade of April (Table 3).

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 acidic) gray forest medium loamy (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.

The analysis of the data presented in tables 2 and 3 shows that the proposed composition is more effective than the prototype: it provides a higher overall crop yield, a high yield of standard products, and also allows you to expand the range of compounds to stimulate the growth and development of agricultural crops, which is necessary due to the high selectivity of plants.
