Description

The invention relates to the field of agriculture, in particular to the meadow fodder production and may find application in improving the productivity of cultivated pastures.

There is a method where high doses of mineral fertilizers are used to increase the productivity of the herbage and irrigation is carried out (patent No. 2474106, published 02.10.2003. IPC A01G 1/00, AV01 79/02, AK23 1/14)

The known method is quite expensive with fractional fertilization and additional seeding of perennial grasses.

There is also known a method in which mineral fertilizers are applied for intensive germination of the grass stand, followed by treatment of the drug Verv extracted from fir green wood (patent No. 2582989, published April 27, 2015. IPC А01С 21/00).

In the known technical solution is carried out 2-fold treatment of the stand with the additional introduction of a biological product, which complicates the method.

The closest technical solution is the method, where in spring, during regrowth, plants are fed with an aqueous solution of the growing leaves of legumes by steaming them in an amount of 5-10% and after cooling the solution Nikfan biological product is added in an amount of 0.1% concentration (patent 2642858, published 29.01. 2018. - IPC А01С 14/00, А01С 21/00 and А01Р 21/00).

In the prototype method, only legume grasses are steamed, which is not enough to fully feed the grass stand in the presence of cereal components to produce food balanced in a sugar-protein ratio. The applied biological product is quite expensive. Moreover, Nikfan added to the cooled solution, which also complicates the method.

The technical result is a simplification of the method and cost reduction.

The technical solution of the claimed object is that, unlike the method of the prototype, during the spring regrowth, the above-ground mass of leguminous and cereal grasses in the amount of 5-10% is cut off, steamed and para-aminobenzoic acid (PABA) is added to the hot solution at a concentration of 0.1% of the volume of the aqueous solution and when cooling it to 20-25 ° C, the plants are fed.

The method is as follows. The grown vegetation of cereals and legumes contains a number of macro- and microelements, flavonoids, antioxidants, and vitamins necessary for the development of phytocenosis. The prepared solution has a complex of substances, balanced by the sugar-protein ratio. As is known, legumes have more protein (18-22%), and cereals have more sugar (10-12%). PABK added to the solution enhances the effect of these elements, increasing the more rapid growth of the grass stand.

PABK has a high biological activity and interaction with the enzymes contained in the aqueous solution of the steamed aboveground biomass. PABA is classified as a non-toxic vitamin-like compound of group B, also known as vitamin H or vitamin B10. PABK is a phenotypic activator and enhances immunity, has antimicrobial effects, and exhibits bioxide functions. At the same time, it affects all the signs that determine the structure of the crop and increase the adaptive properties of plants, including resistance to diseases. Interacting with the enzymes of mowed and steamed herbs growing on cultivated pastures, PABK enhances their growth and development. Considering that PABK powder is dissolved only in hot water, it was added at a concentration of 0.1%. Above these parameters, PABA slows down plant growth, and below these indicators reduces the effectiveness of the method.

Example 1. When the grass was grown on April 10, the leaves of the growing plants of a cultivated pasture were cut: creeping clover, bluefree alfalfa, horned bird and festulolium (fescue and ryegrass hybrid). A mass of 5 kg of green leaves was steamed in 100 liters of water, which was heated to 100 ° C, with the additional administration of 10 g of PABA powder.

After cooling the solution to 20-25 ° C, foliar feeding was carried out on an area of 0.5 ha.

Example 2. A solution was prepared as in the first example, but unlike it, 10 kg of leaves were taken, growing herbs, steaming in 100 liters of water.

Justification of the parameters of the method presented in the table.

The results obtained indicate that foliar treatment of cultivated grazing plants increases plant productivity, improves plant growth, while reducing the cost of mineral fertilizers and various growth stimulants, simplifies the method by simultaneously preparing a solution.
