Description

The invention relates to agriculture, in particular to crop production, and can be used when planting crops of a perennial forage crop of sylpha prilzenolistnoy (Silphium perfoliatum L.).

There is a method of pre-sowing seed treatment of sylvia przednolistnaya, including stratification of seeds for 20-30 days at a temperature of 7 ° C, followed by germination at a temperature of 25 ° C [Stepanov AF The cultivation of prickly leaf sylphy on feed and seeds. A.F. Stepanov, M.P. Chupina, B.G. Sedelnikov. - Omsk, Publishing house of FSEI HPE OmGAU, 2008. - P.22].

The disadvantages of this method are low germination energy and a long period of seed germination.

The closest in technical essence to the proposed method is a method of pre-sowing seed treatment of sylvia proneznolistny, including stratification of seeds for 40-45 days in wet sand at a constant low positive temperature of 1-3 ° C, mixing of seeds [Uteush Yu.A. New promising forage crops / Yu.A. Uteus. - Kiev: Naukova Dumka, 1991. - P.25].

The disadvantage of this method is the low energy of germination, low germination of seeds, a long period of germination.

The technical result consists in increasing the energy of germination, seed germination, reducing the period of seed germination.

The technical result is achieved by the fact that the method of pre-sowing treatment of prickly leaf sylphia seeds, including stratification of seeds for 40 days at a constant low positive temperature - 1-3 ° C, after stratification, the seeds are soaked for 12 hours in an aqueous solution of trace elements: MnSO ₄ concentration of 100 mg / l, ZnSO ₄ - 40 mg / l and CuSO ₄ - 15 mg / l, stratification is carried out in a refrigerator.

Soaking pierced-leaf sylphia seeds for 12 hours in an aqueous solution of trace elements salts: MnSO _{4 at a} concentration of 100 mg / L, ZnSO _{4 at} 40 mg / L and CuSO _{4 at} 15 mg / L increases seed germination energy and seed germination, shortens the period of seed germination. The trace elements Mn, Zn, Cu are powerful catalysts for enzymatic processes in seedlings, take an active part in nitrogen exchange reactions, and significantly change the ratio of nitrogen forms and amino acid composition.

Stratification in the refrigeration chamber improves seed aeration, which significantly increases the germination energy and seed germination.

The method is as follows: the seeds of prickly leaf sylphia are placed in a refrigerator and incubated for 40 days at a temperature of 1-3 ° C for stratification.

Prepare a complex aqueous solution of salts of trace elements, consisting of: MnSO ₄ concentration of 100 mg / l, ZnSO ₄ concentration of 40 mg / l and CuSO ₄ concentration of 15 mg / l. To prepare, take MnSO ₄ - 100 mg, ZnSO ₄ - 40 mg, CuSO ₄ - 15 mg and dissolve in 1 liter of distilled water in a volumetric flask or thin-walled beaker with stirring, for example, with a glass rod until completely dissolved.

After 40 days of stratification, the seeds are soaked in a previously prepared complex aqueous solution of salts of trace elements, consisting of: MnSO _{4 at a} concentration of 100 mg / L, ZnSO _{4 at a} concentration of 40 mg / L and CuSO _{4 at a} concentration of 15 mg / L. To do this, the seeds of sylpha pronzennolistnogo completely immersed in a solution of salts of trace elements and incubated for 12 hours. Then the seeds are dried to a moisture content of 10% and sent for sowing.

Table 1 presents the sowing data of the seeds of sylvia przednosnolistnogo depending on the method of pre-sowing treatment.

Table 1 Sowing data of seeds of sylvia przednosnolistnoy Type of pre-sowing seed treatment Germination energy,% Seed germination,% The appearance of full-grown seedlings, days No stratification (control) 45 61 27 Stratification, 40 days at a temperature of 1-3 ° C 60 75 21 Stratification, 40 days at a temperature of 1-3 ° C in a refrigerator, soaking in an aqueous solution of salts of trace elements with a concentration of: MnSO ₄ - 100 mg / l, ZnSO ₄ - 40 mg / l, CuSO ₄ - 15 mg / l for 12 hours 66 87 fifteen

Analysis of the presented data shows that when treating sylphia seeds with przednolistnoy by the claimed method on the 15th day after laying for germination, the seed germination energy is 66%, laboratory germination rate is 87%. When using only stratification as a presowing treatment, the germination energy is less than 6%, laboratory germination - 12%, and the period of emergence of full-fledged seedlings increases by 5-6 days.

The proposed method for pre-sowing seed treatment of sylvia przednolnistnoy tested in laboratory experiments at the Department of feed production, storage technology and processing of crop products FSBEI HPE OmGAU im. P.A. Stolypin.

This method involves obtaining friendly seedlings of sylvia przednolistnoy, by increasing the intensity of seed germination and reducing the period of occurrence of full-fledged seedlings by 5-6 days.
