Description

The invention relates to the field of agriculture, in particular, to crop production and may find application in the cultivation of oilseeds.

There is a known method of cultivating safflower oilseed crops, in which feeding with an aqueous solution of the natural mineral bischofite is carried out (patent No. 2343666, published 01/20/2009 IPC A01 B 79/02, A01G 1/00, A 231/16).

The known method is quite complicated, since the mineral used must be of a certain density. The safflower oilseed is sown with the combined rows of sunflower.

There is also known a method for foliar processing of oilseeds, where during the period of intensive growth the plant is fed a 5-7% aqueous solution of bischofite (patent No. 2134252, published on 08/10/1999, IPC S05D 9/02, A01C 21/00, A01 No. 59/08) .

However, oilseed plants are fed mainly with magnesium chloride, which is contained in bischofite 94-96%, which does not provide the plants with full nutrition of cultivated oilseeds.

There is a method in which they use a growth regulator - drug Verva extracted from woody fir green (patent No. 2378812, published 01.20.2010, Bull. No. 2, IPC АСС 21/00).

In the known method, oilseeds are treated with the preparation twice: during pre-sowing treatment of seeds and at the beginning of flowering, which is not quite enough to obtain quality indicators for the fatty acid composition, the degree of oxidation of lipids and biologically active components, which play an important role in the storage of oil.

The closest technical solution is a method of increasing the oil content of soybean seeds, in which an aqueous solution of the growth regulator melafen is used, which leads to an increase in the oil content to 22.9% (patent No. 2390984, published June 10, 2010 IPC А01С 1/00).

In the prototype method, only pre-sowing seed treatment is carried out, which is not enough to obtain high-quality and full-fledged oil production - winter camelina seeds.

The technical result is an increase in the efficiency of the method.

The technical solution of the claimed object is that, unlike the prototype, the drug melafen in a concentration of 0.05% aqueous solution is mixed with Nikfan biological product in 0.1% concentration with the addition of sorghum cane syrup in an amount of 1% to the total volume of the prepared mixture and processing the solution is carried out twice: before sowing, the seeds are soaked for 1-2 hours and in the phase of complete flowering of plants as foliar top dressing.

The method is as follows.

Melafen is a melamine salt of bis (oxymethyl) phosphinic acid, which leads to a significant increase in seed germination energy, helps to increase the yield and vegetative mass of plants, and to improve the quality and nutritional value of cultivated crops.

The drug stimulates the respiration of plant cells, increases the cyclic phosphorylation.

Biological product Nikfan enhances plant photosynthesis and root formation, disease resistance and drought tolerance, creating favorable conditions for the environment and increasing the activity of the drug melafen.

Sorghum cane syrup, produced in the Krasnodar Territory, contains a complex of nutrients that increases the vitality of introduced biological products. It contains essential amino acids, ascorbic acid, thiamine, pyridoxine, folic acid, riboflavin, niacin, biotin. Such a complex of substances activates the introduced biological products melafen and Nikfan, provides the metabolism of the winter camelina plant during the feeding phase of the mass flowering phase, when oilseeds are forming.

In the plants of winter camelina, 13 fatty acids were identified, among which linolenic, linoleic, and oleic acids were dominant.

Example. An aqueous solution was prepared for presowing treatment of winter camelina seeds at the rate of 5 g of melafen per 10 l of water. 10 g of Nikfan are taken into this solution. After mixing the two preparations, 100 g of sorghum cane syrup was added. In the resulting solution, 8 kg of winter camelina seeds were soaked (hectare norm) for 1-2 hours, after which the seeds were dried in a dark place until flowability and sown. During the mass flowering period for foliar top dressing, a solution was prepared at the rate of 200 l per hectare, to which 100 g of melafen, 200 g of Nikfan and 2 l of sorghum cane syrup were added.

The parameters of the method are justified experimentally and are tabulated

From the above table it follows that in the proposed embodiment, increased seed yield, oil yield, reduced amount of erucic acid with a simultaneous increase in fatty acids of oleic, linoleic and linolenic.

The proposed version of the claimed object allows to increase the efficiency of the method, and to obtain a high-quality oilseed crop.
