Description

 The invention relates to agriculture and can be used to regulate the growth of wheat plants.

 A known method of stimulating the growth of wheat plants, including the use of an aqueous solution of the culture fluid obtained by growing fodder yeast on a wood hydrolyzate (A.S. USSR 1674714, A 01 C 1/00, 1988).

 This method provides an increase in grain yield, but does not contribute to an increase in the content of crude gluten in grain - the main indicator of its quality.

 A known method of regulating the growth of plants by treating them with a solution of sodium salts of high molecular weight acids (and.with. USSR 809681, A 01 N 37/02, 1979).

 However, the use of this method gives only a slight increase in protein in wheat grain.

 There is also a method of regulating the growth of wheat plants by treating them with sodium salts of humic acids (N. Kvasov. Use of sodium humate and nitrogen fertilizers in order to increase yield and grain quality of winter wheat. Collection of scientific works. Ways to improve grain quality of agricultural crops. Stavropol , 1999) - PROTOTYPE.

 However, the processing of crops with sodium humate leads to an increase in yield, but is not effective enough in terms of improving its quality.

 The purpose of the invention is to increase the yield and quality of wheat grain. This goal is achieved by using, as a growth regulator, the extract from the leaves of the sylpha prilzenolistnoy (Silphium perfoliatum), containing a mixture of biologically active triterpene glycosides.

 To prepare the extract, the air-dry leaves of prickly leaf sylphia, prepared in the flowering phase, are crushed, placed in an airtight container and filled with ether (the ratio of raw material to extractant is 1: 8). Stand for 24 hours at room temperature. The ether extract is separated from the feed by filtration. The operation is repeated 4 more times. Fat-free vegetable raw materials are dried in air, then extracted five times with hot methanol or 70% ethanol. Alcohol extracts are combined, the solvent is distilled off in vacuum. The resulting gummy extract is air dried. The extract contains about 2% (by weight of air-dried raw materials) of the amount of triterpene glycosides with growth-regulating effect.

 For spraying wheat plants using an aqueous solution of the extract at a concentration of 0.2-0.4%.

 Example 1. Plants of winter wheat cultivar Bezostaya 1 were grown in the field according to standard agricultural technology. In the earing phase, the plants were sprayed with a 0.2% aqueous solution of sylphium extract at the rate of 500 l / ha. For comparison, the treatment was carried out at the same time with sodium humate and water (control). The value of the grain yield was determined, as well as the content and elasticity (MPI index) of raw gluten (Table 1).

 As can be seen from the data table. 1 treatment of wheat plants with an extract of sylpha pronzennolistnoy leads to an increase in grain yield and the content of crude gluten in it. In the variant using sodium humate, an increase in the amount of gluten was not noted.

 Example 2. In the field experiments of 1998-2000. winter wheat cultivar Bezostaya 1 was grown according to various predecessors (black steamed and winter wheat - monoculture). In the earing phase, they were sprayed with a 0.4% solution of pronezolistine sylphia extract at the rate of 500 l / ha. In the control variant, the plants were sprayed with water. The experiments showed that spraying the plants with the sylphium extract led to a yield increase when cultivating winter wheat both in black steam and in winter wheat (monoculture) (Table 2).

 Spraying plants with sylphium extract had a positive effect on grain quality (Table 3). The grain content of protein (by 1.3–2.9%) and crude gluten (by 0.5–3.0%) increased, the index of IDK decreased, which helps to improve its baking qualities.

 Thus, based on the above data, we can conclude that the proposed method for regulating the growth of wheat plants increases the grain yield and improves its quality.
