The invention relates to agriculture, in particular to the technology of making of trace elements in liquid form during the growing season of crops.

Known means for foliar treatment of oil-bearing crops, which use natural mineral bischofite (see RU, patent 2134252, C1, M CL605 D 9/02, 01 21/00, A 01 N 59/08. Means the Kaya Federation). - Application 97120819/25; Claimed 11.12.1997; Publ. 10.08.1999).

Natural mineral bischofite formula MgCl26H2O extract from the fields of the Volgograd region by dissolving in water and extrusion under pressure on the day surface. Oily liquid solution (brine) natural mineral bischofite belongs to the category of nesmeshivayuschikhsya liquids. Therefore, the disadvantage of the above method foliar feeding crops bischofite brine is low efficiency. As for major irrigation and method of fine sprinkling (spraying), the smallest droplets bulbs solution mineral bischofite roll down the surface of the leaf blades of agricultural crops. This is particularly evident when feeding vegetables (tomatoes, eggplant, cucumbers) and cucurbits (melons, watermelons, pumpkins) crops due to the peculiarities of the structure of their leaves.

There is also known a method of fine sprinkling of annual crops, where the seasonal irrigation rate to be paid in the form of a single irrigation rates, the parameters of which are determined taking into account climatic indices on the basis of statistical data about quantities is,15.05.02).

The disadvantage of this method is the uncertainty of the parameters of the vegetation fertilizing agricultural crops.

Also there is a method of growing fertilizing irrigated crops, we adopted the closest analogue, comprising preparing a solution of fertilizers in irrigation water and periodic irrigation of plants with a sprinkler, in which, to improve the digestibility of fertilizer plants, irrigation is carried out in conditions of low-volume irrigation, wetting-drying at the rate of solution flow rate of fertilizers on wetting 2...10 m3/ha and duration of the drying period 8...12 min depending on meteorological conditions with a repetition cycle of wetting-drying to make the necessary dose of fertilizers (SU authorship 1806517 A1, M CL5A 01 WITH 21/00. The way the vegetation fertilizing irrigated crops / R. P. Zadneprovsky and centuries Serebryakov (USSR). - Application 4887133115; Claimed 25.10.1991; Publ. 07.04.1993. - Bull. 13).

The disadvantages of this method include the high standards a single fertilizer, resulting in burns leaf surface; low efficiency of absorption of plant fertilizers, no the purpose.

The essence of the claimed invention.

The problem to which the invention is directed, - improving the efficiency of absorption by the plants fertilizers under controlled phytoclimate crops.

The technical result is to increase the yield and quality of agricultural products.

This technical result is achieved by the fact that in the known method of growing fertilizing agricultural crops, comprising preparing an aqueous solution of fertilizer and periodic irrigation of plants using a fine sprinkling, according to the invention vegetation feeding combined with the diurnal cycle regulation phytoclimate crops method of fine sprinkling in the days when the ambient temperature exceeds the biologically optimal for crops, while growing feeding solution fertilizers combined with a final sprinkling vnutrisutochnogo cycle when the rate of flow of solution fertilizers 2...6 m3/ha; vegetation feeding and regulation of phytoclimate method fine sprinkling of winter wheat do with 10...11 to 17...19 h at intervals of 0,5...2,0 h on days when temperatures which are a mixture of brine natural mineral bischofite sulfate type and adhesive substances on the basis of 16...22% solution of starch adhesive with a viscosity of 12. . . 20 cSt, with bischofite brine and mortar are in a mixture in the ratio 2:1...4:1.

The drawing shows a graph of air temperature changes during the day for various years in the heat supply (5...90%) in the Volgograd region.

Information confirming the possibility of implementing the inventive method are as follows.

Technology is growing fertilizing using brine natural mineral bischofite irrigated crops include sequential execution of the following technological operations: preparation of solutions of fertilizers in irrigation water; periodic irrigation with dissolved mineral fertilizers with sprinkler (DDN-70, PCI-100, DD-30 and others) or converted dual console sprinkler units DDA-100 MA or DDA-100 BX (designed by JSC "Volgograd plant irrigation techniques "WATT").

Regulation of phytoclimate crops method of fine sprinkling (DMD) perform in the critical days of the vegetation period, when the ambient temperature exceeds the biologically optimal for cultivated crops. When this vegetation feeding solution Udo is..6 m3/ha.

In particular, for winter wheat fertilization and vegetation control phytoclimate method fine sprinkling perform in those days, when the ambient temperature exceeds 22...25oWith depending on grade (see attached graph of the diurnal variation of ambient temperature). Regulation of phytoclimate crops DMD method is carried out in the period from 10. . . 11 to 17...19 h at intervals of 0,5...2,0 h single irrigation depths 4 m3/ha.

As a solution fertilizer use brine natural mineral bischofite sulfate type formula MgCl26H2O. the Composition of the samples of the brine leaching of bischofite produced in Gorodishche and Narimanov fields of the Volgograd region, are given in table. 1. Chemical analysis of brines made in laboratories, Volgograd, depending on the place of production of bischofite, shown in the table. 2. The content of macro - and micro elements, in particular in bischofite brine from wells 4 Gorodishche field is given in table. 3.

Due to the nonwettability lamina most crops bischofite brine it is applied to the surface of crops (leaves and stems) cultivated Cho glue.

When the ambient temperature is above +20oC and wind speeds greater than 5 m/s using a 16% solution of starch glue. At high humidity and ambient temperatures of less than +20oWith use 22% of the adhesive based on starch.

In the composition of the adhesive with a viscosity of 12...15 cSt for foliar feeding when the air temperature is more than +20oWith include: starch - 42,4 kg; borax 0,39 kg; caustic soda - 0,94 kg; water - 210 kg

In the adhesive with a viscosity of 18...20 cSt includes: starch - 61 kg; borax - 0,39 kg; caustic soda - 0,91 kg; water - 210 kg (l).

In a mixture of bischofite brine and mortar are in the ratio 2:1...4: 1.

In table. 4 shows data for 2000...2001 multifactor field experiments to investigate the influence on the yield foliar treatment of winter wheat varieties of the don region, confirming the efficiency of foliar feeding bischofite brine as a carrier of macro - and microelements on the background of the regulation of phytoclimate crops method of fine sprinkling.

Thus, presents the results of the pilot test indicate a high efficiency of foliar nutrition of agricultural plants bischofite brine in combination with an adhesive agent, held tablemaintaining sprinkling.
