Abstract

FIELD: chemistry.

SUBSTANCE: mulching composition is characterised by that it contains lignosulphonate, carbamide, NA-carboxymethyl cellulose, potassium chloride and, as natural additives, Takakiopsida moss and Juniperus h. Wiltonii juniper needles, and water in the following ratios, wt %: lignosulphonate 0.1-0.4, carbamide 0.2-0.6, NA-carboxymethyl cellulose 0.3-0.4, potassium chloride 1-3, Takakiopsida moss 10-15, Juniperus h. Wiltonii juniper needles 8-9, water - the balance. Other versions of polymer-natural mulching compositions are also disclosed.

EFFECT: wider range of soil mulching compositions.

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, urea 0 , 4-0.8, potassium chloride 1-3, water the rest (Russian patent No. 2034899 C1, 1995, CL 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 this 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 moss of the Takakiopsida species and juniper needles Juniperus h as natural additives. Wiltonii, water in the following ratio, wt.%:

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

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

moss species Takakiopsida 10-15 juniper needles Juniperus h. Wiltonii 9.1-9.5

or

moss species Takakiopsida 10-15 juniper needles Juniperus h. Wiltonii 9.8-11

The composition is prepared as follows.

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