Description

The invention relates to agriculture, in particular to meadow cultivation and forage production, and may find application in increasing the growth and development of plants of cultivated hayfields and pastures.

There is a method in which, in the spring regrowth of plants, mineral fertilizers are applied by foliar feeding in doses of N ₃₀ P ₄₅ K ₄₅ followed by treatment of vegetative plants with Verva biological product extracted from fir green wood (patent No. 2582989, published April 27, 2015, IPC А01С 21 / 00).

However, the known technical solution is somewhat complicated due to the 2-fold treatment with minerals and biological product, which increases the cost of implementing the method.

There is also a method where, to increase the productivity of pastures, grass is sown, the seeds of which are treated with Extrasol-55 biological product in a mixture with zeolite-containing clay alanite, ash and urea in a certain ratio (patent No. 2431248, published October 20, 2011, IPC А01С 7/00 A01C 79/02).

The method is taken as the closest analogue and its disadvantage is the low results of the technical solution, since on the sloping lands in the presence of water erosion and spring precipitation, the mineral and biological composition of the treated seeds can lower their performance without achieving the desired effect. In addition, the used mineral ingredients are quite expensive.

The objective of the invention is to simplify the method and reduce costs through the use of local and low-cost funds.

The technical result from the use of the invention is to increase the efficiency of operation of cultivated hayfields and pastures, increase the yield of fodder mass.

The technical result is achieved by the fact that foliar top dressing of the growing grass in spring is carried out with an aqueous solution of growing bean herbs by steaming the leaves in an amount of 5-10%, and after cooling the solution and filtering it, Nikfan is additionally introduced in an amount of 0.1% of the total liquid volume.

The method is as follows.

Legumes present on grass pasture (creeping clover and blue alfalfa) have properties that are highly useful for all living organisms, in particular pectins, fatty acids, essential oils, saponins, plant steroids, triterpene enzymes, carotene and a number of vitamins (E, C, K, B - the whole group and others), which restore weakened plants during the winter period, accelerate the metabolism of not only leguminous components, but also cereals present in the grass stand. The Nikfan biological product added to the cooled solution increases the nitrogen-fixing nodule bacteria on the roots of legumes, enriching the soil with biological nitrogen.

Biological product Nikfan enhances root formation and photosynthesis, resistance to diseases, improves symbiosis with nitrogen-fixing bacteria. Due to the active activity of plants, their accumulating activity increases, heavy metals, nitrates and radionuclides decrease in the soil. The main active components of the drug are the products of the producer’s metabolism: amino acids, enzymes, growth substances, including phytohormones (cytokinins, auxins, as well as components containing humic substances and substances that ensure the stability of the drug’s properties during the warranty period. Observed biological effects of the biological product are achieved by improving the nutrition of vegetative organs, stimulating photosynthesis, regulating the work of plant genes at the molecular level the principle of hormonal signals in plants due to the penetration of the active parts of the drug using protein receptors through the cell membrane of the plant.The drug Nikfan in concentrations of 0.1% aqueous solution reaches high efficiency when dissolved in 5-10% aqueous solution of legumes. The prepared solution is justified by its stimulating and regenerating effect as an activator of living organisms, including various strains.

Example 1. When growing grass pasture of a cultural pasture, a solution was prepared from the leaves of legumes (alfalfa bluehybrid and clover creeping (white) at a rate of 50 g per 10 liters of water. Leaves of legumes were lowered into hot water (90-100 ° C), insisted until cooling 20 -25 ° C and the Nikfan biological product was dissolved in strained water in an amount of 10 ml per 10 liters of water. The resulting solution was applied to herbage over an area of 50 m ² (in 3-fold repetition). 200 l of solution was prepared per hectare.

Example 2. The grown leaves of bean herbs in an amount of 100 g were steamed in 10 l of water, insisted, filtered and 10 ml of Nikfan biological product (0.1%) was added to the resulting solution. The liquid flow rate per hectare is in the range of 200-250 liters.

The results are summarized in table.

From the given data of the experimental results, it follows that top dressing during the spring growth period with low-cost natural elements by sources of raw materials provides an increase in the resulting mass and improves the growth and development of plants, while enriching the soil with nutrients, in particular biological nitrogen. Using natural energy resources, you can simplify the method and get additional products at no additional cost.
