Composition for stimulating growth and development of crops

 

Describes a composition for stimulating the growth and development of crops in the following ratio, wt.%: alkanolamine 5,0-35,0; citric acid 2,5-20,0; zinc compounds or copper 1,0-20,0; water - the rest. The resulting compositions are used for foliar fertilization of cultures, as well as pre-sowing treatment of seeds. The technical result consists in increasing the yield of agricultural 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.

and copper sulfate, or chloride

copper or copper coal preparation composition using known chemical substances: monoethanolamine (IEA) TU 6-09-2447-90 or THE 602-915-84, or diethanolamin (deja) TU 6-09-2652-91, or triethanolamine (tea) TU 6-02-916-79.

As of zinc compounds can be used, for example, zinc oxide according to GOST 10262-73, or zinc sulfate ZnSO4·7H2O, or zinc chloride, ZnCl2according to GOST 4529-78.

As copper salts can be used, for example: copper sulfate CuSO4·5H2About GOST 19347-84, or copper acetate according to GOST 5852-79, or copper carbonate basic GOST 8927-79, or copper chloride CuCl2·2H2O according to GOST 4167-74.

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 No. 1 (proposed).

Mix 58.5 g of water, 4 g of zinc oxide, 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 No. 2-7, No. 9-12 carried out analogously to example No. 1, changing the qualitative and the quantitative ratio of the components. The composition of the obtained compounds are shown in table 1.

Example No. 8 (prototype).

The resulting composition is a clear liquid dark purple color density of 1.0-1, the medium loamy soil agrochemical characteristics of the topsoil: srednekislye reaction medium pH 4-9; low humus content of 3.45; a very high content of phosphorus 272,5 µg/kg; high content of exchangeable potassium 140 mg/kg Availability zinc low of 0.11 mg/kg; copper average 3,86 mg/kg soil. The research object is the sort of Radon (winter rye), grade Kazan (winter wheat), carrots (sort of Santana), peas (grade Worker), vetch (grade Lgov). The size of plots is 12 m2, an area of 10 m2.

Studies conducted on the background of the full mineral fertilizer rate of N120P70To100. Agriculture - traditional.

Seed treatment carried out for 2-3 days before sowing. The flow tank liquid was 15 l/T. 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 the working composition is 1.2%. The test results of the compositions are shown in table 2.

Analysis of the data presented in table 2 shows that the proposed formulation is more effective in comparison with prototype: it provides high yields of agricultural crops and allows 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.
