Description

The invention relates to the field of agriculture, in particular to vegetable growing and may find application in growing products in closed agrobiotechnological systems

There is a method in which humus-containing substances are used - vermicomposting, providing an increase in plant productivity (Yu. Kalinina, O. Chertov, A. Popov “Changing the composition and agroecological properties of livestock waste in the composting process with the participation of Eisenia faetida earthworms.” Soil science No. 9, 2002, p. 1072-1080).

However, such a composition of fertilizers is prepared for field conditions, which does not ensure the complete safety of the applied types of fertilizers and their equal distribution in the soil horizon.

The closest technical solution is the method where they prepare vermicompost with the inclusion of zoocompost, sapropopel, brown coal and the whole composition is soaked in water (patent No. 2256441, published 20.08.2004, Bull. No. 23. IPC C05F 3/00, C05F 11/02)

The disadvantage of the prototype method is that after soaking in water, the alkaline extract is separated and neutralized with subsequent microbiological fermentation with an increase in the biomass of soil microorganisms at a temperature of 20-35 ° C for 3-24 hours with continuous aeration. The whole process complicates the method and costs of obtaining such fertilizer. In addition, the technologies for its use have not been developed, especially for protected ground conditions, and even more so for closed and closed agrobiotechnological systems such as phytotrons and modern systems based on digital technologies of the synergotron class. The dosage of the drug and the periods of application of this fertilizer to ensure the quality and quantity of vegetable products are not justified.

The technical result is the justification of the dose and timing of the use of a new biological product, reducing costs for use in closed agrobiotechnological systems.

The technical solution of the claimed object is that, unlike the known method - the prototype, the Niva biological product containing a number of microorganisms, humic components and a complex of micro and macro elements without lipids are used in closed agrobiotechnological systems in an amount of 5 vol. % aqueous solution once during the growing season as foliar feeding on the 18-20 day of plant vegetation.

The method is as follows.

The drug "Niva" is an extract of humic acids isolated from vermicompost and, unlike other types of fertilizers of this type, does not contain toxic lipids for plants. The drug contains a number of macro- and microelements. The main way to use it is non-root top dressing. A single treatment during the growing season increases the influx of trace elements to growing tissues and ensures intensive growth of the vegetative part and root system throughout the entire growing season. Foliar treatment of plants is the most effective means of biological correction of their development. Such an agricultural method allows to ensure the nutrient cycle, optimize plant respiration, accelerate the course of biosynthesis and shorten the growing season, reduce the nitrate content in products, increase yield and product quality. The parameters of the method are experimentally justified

Example. In the closed system of the phytotron ISR-0.1 (developed by ANO “Institute for Development Strategies”), an experiment was conducted on leaf lettuce of the Ballet variety. Plant growing conditions: hydroponic system, substrate - mineral wool. Used blocks 33 cm long, 10 cm wide, 7.5 cm high. In one block 4 seats. During the growing season, on the 18-20th day of the growing season, with sufficient development of the leaf surface, small-droplet spraying of an aqueous solution of the humic preparation was carried out on leaves at the rate of 50 ml of the Niva biological product per 1 liter of water.

The results of the experiments are summarized in tables.

From the above table data it follows that the preparation in the closed system of the phytotron ISR-0.1 provides an increase and product quality even for one foliar top dressing, thereby reducing the cost of implementing the method
