A method of manufacturing a nutritional tablets for growing plants

 

(57) Abstract:

The invention relates to agriculture and can be used in the manufacture of extruded food tablets for growing seedlings of agricultural and flower crops, as well as organic fertilizers for the main filling of soil in home gardens and in greenhouses. As a substrate for tablets use peat and bird droppings, and drying is carried out until the air-dry condition of the substrate. Then milled peat to particle size 1.0 mm to 8.0 mm, and bird droppings - to 0.5-2.5 mm Then peat and bird droppings are mixed in the mixer from the calculation of 3.0-3.5: 1.0 to 1.5 and pressed into tablets. Tablets in its composition are in optimal quantities and the ratio of nitrogen, phosphorus, potassium, calcium, magnesium and some trace elements without adding costly mineral fertilizers. The resulting product is environmentally friendly, convenient for packing and shipping. 3 C.p. f-crystals.

The invention relates to agriculture and can be used in the manufacture of extruded food tablets for growing seedlings of agricultural and flower crops, as well as organic fertilizers for osprey production of extruded substrates, including separation of extraneous inclusions, shredding peat and its drying in the fluidized bed, peat milled to average particle size of 0.5-2.5 mm Dried peat is mixed with mineral additives as binders using bitumen emulsion /A. with. N 397165 and 1701728, MKI A 0 G 9/10/.

Known methods for producing granulated peat, including grinding, drying of milled peat to a moisture content of 45-55%, mixing and pushing through cylindrical holes /A. with. 1747466, and.with. 664988, C 10 F 7/04/.

However, the known methods do not provide adequate quality due to low strength, small volume of substrate and low chemical composition due to the inertia of peat without biologically active components.

The closest technical solution to the proposed method is a method for the production of briquettes peat nutrient for growing seedlings, including shredding peat until the particle size of 1-5 mm, mixing the components to obtain peat-mineral mixture and drying in the fluidized bed at 30-40oC to a moisture content of 20-30%, presovanje /A. with. 397165, A 01 G 9/10/.

However, this method has the following disadvantages: low quality due to the additional use of mineral supplements in the form of mineral fertilizers, containing a small admixture of heavy metals.

It is known that peat in severedbytes the state does not have the right to grow plants nourishing properties.

The present invention is to obtain high quality, organic nutrient tablets, high strength and convenient for packaging and transport due to small volume.

The objective is realized in that the method includes grinding the substrate, drying, mixing, pressing, as the substrate, two components are used - peat and bird droppings; the drying is carried out before grinding, and carry it to air-dry state of the substrate, and then crushed, mixed and pressed under pressure /60 MPa/ tablets. Grinding is carried out until the particle size: peat from 1.0 to 8.0 mm, bird droppings from 0.5 to 2.5 mm, the Mixing of these components of the calculation of 3.0 - 3.5 : 1.0 to 1.5 spend mixer.

The method is as follows.

Pure peat moss and bird droppings are dried to air-dry state to provide tablets high strength, then crushed in the crusher to the size of the particles of peat from 1.0 to 8.0 mm, bird droppings 0.5 to 2.5 mm Shredding peat to an increase in bird droppings less than 0.5 or more than 2.5 mm reduces the nutrient regime in connection with uneven adsorption processes of peat.

After grinding peat and manure are mixed in the mixer from the calculation of 3.0 - 3.5 : 1.0 to 1.5. The resulting mixture was unloaded in a conical hopper to congestion, from which it enters the matrix camera, and pressed under high pressure into tablets, possibly pressing and other types of briquettes. Further, the products are fed to the filling, and then stored.

Experimentally revealed that the most favorable impact on the growth and development of plants has fractional composition of peat 1.0 mm to 8.0 mm, and a litter of 0.5 : 2.5 mm At a ratio of peat: litter 3.0 to 3.5 : 1.0 to 1.5 tablets in its composition are in the optimal quantity and ratio of macro - and micronutrients /nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, manganese, copper, zinc, molybdenum and other elements of/ without the addition of expensive mineral components in the form of fertilizers. The resulting products are ecologically pure, biologically active substrate with high water-holding capacity, degree of homogenization, "gently and gradually /in "installments"/, mineralizes, works on plant nutrition. The obtained products are manufactured in the form of an experimental batch and tested on the experimental training farm fields N 1 Omgaw.

For growing seedlings tablet is placed into the container /putsa plants or placed seeds of vegetable and flower crops. Morphometry tablets have high environmental and agrochemical parameters on the chemical composition of most agronomic, economic and bio-energetic effect. Dry TFT has a mass of 0.05 - 0.250 kg, a size of 65 mm in diameter and 15 to 30 mm height, during storage and transportation do not change the strength, form and set properties. The proposed method of manufacturing morphometric tablets the cheapest and most environmentally justified. When hydration tablet fast /5 - 7 min and 7-fold increases in volume with the formation of optimal parameters of water, air, nutrient regimes, necessary for normal growth of plants.
