Description

The invention relates to the chemistry of synthetic substances - polymeric in mixture with organic and natural substances, for example, for urban and agricultural purposes or to compositions for mulching various types of soils, lawns, park areas.

Previously known was the composition of the mulching coating, in which polyacrylamide, urea, lignosulfonate, potassium chloride and water were used in the following ratio, wt.%: Polyacrylamide 0.25-0.75, lignosulfonate 0.5-1.5, carbamide 0.4 -0.8, potassium chloride 1-3, water the rest (Russian patent No. 2034899 C1,1995, class of international classification of patents С09К 17/00).

But such a patent did not use natural materials - this is a significant drawback. In nature, there are many materials suitable for this - many mosses, various types of wood waste, bark, shavings, wood chips. Moreover, different types of wood can be combined with different types of synthetic materials - polymers, their waste, if they are harmless to the environment.

In the invention, the technical result is the use of numerous types of natural materials, that is, the expansion of the arsenal of compositions for mulching soils.

This result is achieved in that the composition of the mulching coating according to the invention contains lignosulfonate, urea, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Conocephalum and needles of Juniperus squamata Holger juniper, water in the following wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss species Conocephalum 10-15 juniper needles Juniperus squamata Holger 8-9 water rest

As options, the following compositions were invented, in which important ratios for moss and needles were changed (selected):

moss species Conocephalum 10-15 juniper needles Juniperus squamata Holger 9.1-9.5

or

moss species Conocephalum 10-15 juniper needles Juniperus squamata Holger 9.8-11

The composition is prepared as follows.

These ingredients are individually milled and then mixed in an aqueous medium.
