Description

The invention relates to pulp production and can be used in agriculture for various crops.

Known is a complex fertilizer based on nitrophosphate, containing boron as a microelement, the use of which allows you to get a grain yield of winter wheat 48.3 c / ha, and a corn crop 84 c / ha. (Complex fertilizers. Reference manual, M. Kolos, 1979, p. 88).

The disadvantages of the known fertilizer include the low productivity of these crops, as well as a limited set of nutrients.

Nitrogen fertilizer with micronutrients and a biologically active additive is known, containing urea, ammonium nitrate, hydrohumate, brassinosteroids, copper, manganese, a polymer binder, corrosion inhibitor and water, when using which the yield of grain crops is 53.9-57.2 c / ha ( winter triticale) and 44.7-54.1 c / ha (malting barley), as well as a method for its production, including mixing aqueous solutions of urea and ammonium nitrate, cooling the mixture, introducing a corrosion inhibitor and biological additives of brassiosteroids, and / or and, and / or manganese, or together copper and manganese, and / or a polymer binder at a pH of a mixture of 7.0-8.5 (Eurasian patent No. 013002, CL C05C 13/00, C05I 9/02, publ. 2010.02. 26).

The disadvantages of this fertilizer include the low yield of grain crops and the complexity of the process of obtaining the finished product.

The closest in technical essence and the achieved result to the claimed technical solution is a complex fertilizer with chelated forms of trace elements containing the following components, wt.%:

nitrogen - 1.7-15.0, phosphorus - 5.0-15.0, potassium - 1.5-10.0, trace elements:

boron (by element) - 0.10-0.20, copper (in chelate form) - up to 0.10, zinc (in chelate form) - 0.0-0.14, manganese (in chelate form) - 0, 0-0.10, molybdenum (in chelate form) - 0.0-0.01, cobalt (in chelate form) - 0.0-0.001, sodium - 0.0-1.0, trilon - 0.44- 1.60, water - the rest, and a method for its preparation, including the preparation of a solution of chelated forms of trace elements and its introduction into a basic solution obtained by dissolving a gallurgic potassium chloride and urea in an aqueous solution of ammonia, followed by non-neutralization of boric and phosphoric acids to pH 6.06 5 (Eurasian patent No. 013014 , CL S05I 9/02, publ. 2010.02.26).

The disadvantages of fertilizer prototype is a low increase in crop yields (from 10 to 25%) and the complexity of the process of obtaining it.

The objective of the invention is to develop a complex fertilizer composition with chelated forms of trace elements and a method for its preparation.

The technical result consists in increasing the yield of crops.

The technical result is achieved by a composition comprising nitrogen, phosphorus, potassium, as well as microelements boron, chelate forms of copper, zinc, manganese, molybdenum, cobalt, iron and protein plant mass of the family TGoPshp b., Protein plant mass of the family Karyaiik 8uyu8, chlorophyll plant mass of the genus Lpyrsgyih dextrin in the following ratio of all components, wt.%:

nitrogen - 0.5-98.9682, phosphorus - 0.5-99.1, potassium - 0.3-97.982, trace elements:

boron (by element) - (2.5-72.0) x 10 ^-5 , copper (in chelate form) - (5.0-144.0) x 10 ^-5 , zinc (in chelate form) - (12 5-360.0) x 10 ^-5 , manganese (in chelate form) - (5.0-144.0) x 10 ^-5 , molybdenum (in chelate form) - (10.0-288.0) x10 ^-5 , cobalt (in chelate form) - (2.7-72.0) x 10 ^-5 , iron (in chelate form) - (12.5-360.0) x 10 ^-5 , protein plant mass of the TTKoyit family B. - (1.7-48.0) x 10 ^-4 , protein vegetable mass of the Rarnapus OaOusch family - (1.7-48.0) x 10 ^-4 , chlorophyllic plant mass of the genus Lnirmschs - (1.7-48.0) x 10 ^-4 ,

- 1 022545 dextrin - the rest.

Significant differences between the claimed composition of the complex fertilizer from the composition according to the prototype is that iron (P) (in chelate form), as well as the protein plant mass of the ΤπΙοιιιιη b. Family, the protein plant mass of the Karbapik 8ayuik family, and the chlorophyll plant a mass of the genus Lniregik and dextrin as an adhesive with the claimed ratio of components. This allows you to increase the yield of vegetables and crops by stimulating soil microorganisms vital for plants, as well as accelerate plant growth and development, and increase the resistance of the latter to adverse environmental conditions.

The inventive complex fertilizer composition with chelated forms of trace elements is obtained by a method including preparing a solution of chelated forms of trace elements and introducing a dextrin adhesive, mixing until complete dissolution, neutralizing the solution with boric acid, followed by compounding with the base fertilizer and drying the finished product at room temperature. The connection with the base fertilizer is carried out by surface treatment of the granular base fertilizer or by introducing it at the granulation stage of the base fertilizer.

The inventive method differs from the prototype method by the introduction of adhesive-dextrin, neutralization at the stage of preparing a solution of chelated forms of trace elements and drying the finished product at room temperature, as well as the process of combining with the base component: either by surface treatment of the granular base fertilizer, or by introducing it at the stage granulation of the base fertilizer.

The fertilizer was tested on spring soft wheat at the farms of Ivolga Holding LLP in the Kostanay region of the Republic of Kazakhstan, while the yield increase was 30-40%.

Example. Pre-prepared solution of trace elements in chelated form. To do this, 0.22 g of the protein plant mass of the family Tgobyl b., 0.22 g of the protein plant mass of the family Karbaiik 8aDuik and 0.22 g of chlorophyllic plant mass of the genus Kpregik are dissolved in 0.98 dm ^{3 of} water at a temperature of 60 ° C. mix until completely dissolved. Then, 0.26 g of copper sulfate, 0.727 g of zinc sulfate, 0.293 g of manganese sulfate, 0.334 g of ammonium molybdate, 0.158 g of cobalt sulfate, 0.288 g of iron sulfate are added to the solution and 22 g of dextrin as an adhesive are added, and then they are mixed until complete dissolution . The resulting solution is neutralized with 0.196 g of boric acid, followed by surface treatment of 21.73 kg of urea with continuous stirring and drying of the finished product at room temperature. The yield of spring soft wheat when using this composition of the proposed fertilizer is increased by 32.4%. This composition corresponds to the following ratio, wt.%: 99.9768 Ν, 3.3x10 ^-5 V, 6.6x10 ^-5 Cu, 16.5x10 ^-5 Ζη, 6.6x10 ^-5 MP, 13.2x10 ^-5 Mo, 3.3 x 10 ^-5 Co, 16.5 x 10 ^-5 Fe, 2.2 x 10 ^-4 protein plant mass of the family TgNysht b., 2.2 x 10 ^-4 protein plant mass of the family Carnapikiaduek, 2.2 x 10 ^-4 chlorophyll plant mass of the genus. , 2.2 x 10 ^-2 dextrin.

Other examples are given in the table.

As can be seen from the table, the proposed complex fertilizer can increase crop yields by 30-40%.
