Description

The invention relates to the chemistry of synthetic substances - polymeric mixed 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, such a mulching coating composition was known 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, urea 0, 4-0.8, potassium chloride 1-3, water the rest (Russian patent No. 2034899 C1, 1995, class of international classification of patents, C09K 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 my invention, the technical result is the use of numerous types of natural materials, that is, expanding 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 Moerckia and needles of juniper Juniperus virginiana Kobold, water in the wake. wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss species Moerckia 10-15 juniper needles Juniperus virginiana Kobold 8-9 water rest.

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

moss species Moerckia 10-15 juniper needles Juniperus virginiana Kobold 9.1-9.5

or

moss species Moerckia 10-15 juniper needles Juniperus virginiana Kobold 9.8-11

or

moss species Moerckia 15,5-17 juniper needles Juniperus virginiana Kobold 8-9

or

moss species Moerckia 17.8-18 juniper needles Juniperus virginiana Kobold 8-9

or

moss species Moerckia 17.8-18 juniper needles Juniperus virginiana Kobold 9.8-10

The composition is prepared as follows.

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