Description

The invention relates to the production of liquid compound fertilizers. Liquid compound fertilizers can be used to fertilize garden, greenhouse and outdoor plants.

Plants are often fertilized with mineral fertilizers containing the main nutrients ~ macronutrients nitrogen, phosphorus, potassium. Fertilizers containing secondary macronutrients - calcium, magnesium sulfur and micronutrients - zinc, copper, manganese, molybdenum, cobalt, boron, iron, selenium, etc. - can be used.

Biologically active substances - growth activators, also called bio-stimulators or bio-activators - are also increasingly used in agricultural intensification. These are natural or synthetic compounds that, even in very small amounts, cause significant changes in the growth and development of the plant. Once in the plant, they are directly involved in the metabolic processes, influencing the plant's regulatory system, which determines growth and changes in the vegetation stages (growth - flowering fruit - dormancy or exit - etc.) and thus has a wide range of effects on plants.

However, the use of growth activators is not an artificial intrusion into the plant's developmental stages. In nature, growth regulators exist naturally in the plants themselves and control all plant vegetation processes. They are called phytohormones, and they start to work only under certain conditions: temperature, lighting, humidity.

The effects of growth activators may be selective, i. that is, they can affect root system development, photosynthesis, flowering, fruiting, etc. Growth activators enable the potential of plants to be realized, regulate fruit maturation to improve quality and increase productivity.

Another important feature of growth activators is their ability to increase plant resistance to disease, pests and adverse climatic conditions.

It is known that growth activators may include various substances: auxins, giberillins, succinic acid, brasinolides, various humic acids and their derivatives, various ethyl esters of fatty acids and other substances.

The technical-economic benefits of growth activators derived from natural raw materials are: unique and effective preparations even at low doses; the products are environmentally friendly, harmless to animals and humans, and do not accumulate in plants or soil. Various wastes from other production processes can be used to make these preparations.

Economically rational, when these active substances are used in combination with fertilizers.

Known growth activator for Penergetic-p leaves, manufactured by the Swiss company Penergetic International AG using special technology for molasses processing and used for spraying or staining plants. This product activates microorganisms in the soil, better uptake of nutrients, increases the assimilation area of the plants, increases the process of photosynthesis, resulting in higher quality and higher yields (Penergetic). However, using Penergetic-p requires additional fertilization.

It is known to use molasses with other components after spraying to produce spray fertilizers (patent CN 1343644), as well as a method for using fertilizer processing residues containing saccharides, molasses, sugar, dextrins, etc. as growth activators in fertilizer production. (patent JP 9100189).

The closest known technical solution is liquid compound fertilizer (patent LT 5026). Their disadvantage is that liquid fertilizers contain only primary and secondary macronutrients and micronutrients.

Patented Liquid Compound Fertilizers that contain growth activators in addition to the primary, secondary, and micro-nutrients. The macronutrient ratio N: P: K is (0 +3) :( 3 + 0) :( 0 + 3) and the amount of components (in percentage by weight) is:

nitrogen 0 + 34 phosphorus (P2O3) 0 + 37 potassium (K ₂ O) 0 + 10 of secondary macronutrients 0 + 4 of trace elements 0.01 + 0.8 growth activator 0.01 + 1.0 water up to 100.

In patented fertilizers, the growth activator is Penergetic-p, which is produced by a special technology of molasses treatment.

These fertilizers use as a nitrogen component bulk or dissolved nitrates, amines, amides, ammonium compounds or mixtures thereof. The phosphorus component uses polyphosphoric, orthophosphoric acids or salts of polyphosphoric orthophosphoric acids, or mixtures thereof, or solutions thereof. Potassium component uses potassium in bulk or dissolved nitrates, sulphates, phosphates, carbonates or mixtures thereof. Components of the secondary macronutrients (Ca, Mg, S) may be salts, oxides, hydroxides or mixtures thereof. The micronutrient component uses bulk or dissolved oxides of zinc, copper, boron, cobalt, manganese, molybdenum, iron, salts, chelating agents, boric acid or mixtures thereof.

The main constituent of the growth activators Penergetic-p is molasses treated with a special technology and specially adapted to plants. This product is organic and harmless.

The technical characteristics of liquid compound fertilizers can be determined by the following methods: nitrogen mass,% - photochromimetric, formaldehyde, Kjeldahl; mass of phosphorus,% - by photochromimetry;

mass of potassium,% by flame photometer;

Mass of Ca, Mg,% - complexonometric;

S mass,% - gravimetric;

mass of trace elements,% - atomic absorption analysis;

pH - pH meter;

density - with hydrometer;

viscosity - viscometer;

crystallization temperature - visual polythermic method;

refractive index - refractometer.

Patented fertilizers are manufactured as follows:

Patented liquid fertilizers with growth activator Penergetic-p did not change their storage properties.

Patented liquid compound fertilizers with growth activators have the following advantages over prototype:

- diversified nutrient ratios and higher concentrations, which can reduce fertilizer rates;

- liquid complex fertilizers enriched with growth activators are more effective: they activate microorganisms in soil; forms a more lush root system; improves nutrient uptake; the assimilation area of the plants increases; the process of photosynthesis becomes more active; yields increase, quality, biological and energy value.
