FIELD: agriculture. ^ SUBSTANCE: invention relates to agriculture, i.e. to bio-stimulating and growth-controlling means intended for plants growing and harvest increasing. The above method includes top-dressing of vegetative plant by means of mineral fertiliser solution consisting of chemical substances with nutrient elements such as boron, manganese, copper and molybdenum. In addition, the solution includes chemical substances containing iron, potassium, zinc, nickel, iodine, cobalt, sulfur, aluminium, tin and strontium. The weight of each chemical substance to be used for mineral fertiliser solution preparation is defined to the standard weight of separate mineral fertiliser being in 100 g of the fall wheat and according to the formula: where m(B) -weight of the chemical substance (S) included into the fertiliser weight and having one nutrient element (E); Mr(S) - relative molecular mass of the chemical substance (S) to be defined to the Mendeleev Table based on the chemical formula of the substance; m'(E) - weight of separate nutrient elements (E) in 100 grams of the grains expressed in grams; Ar(E) - relative atomic weight of the nutrient element (E) included into the chemical substance (S). After that, water solution of mineral fertilizers is prepared at concentrations 0.0686/0.1% containing all calculated chemical substances. The crops of the fall wheat are then treated with the above solution in the amount of 100-300 l per 1 crop hectare. ^ EFFECT: increase of fall wheat crop-producing power due to nutrient fertiliser solution optimisation for top dressing. ^ 2 tbl |
