Mulching composition (versions)

FIELD: chemistry.

SUBSTANCE: mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride, natural additives - Conocephalum moss and Larix koreana larch 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, Conocephalum moss 10-15, Larix koreana larch needles 8-9, water - the balance. Other versions of the polymer-natural mulching composition are also disclosed.

EFFECT: wider range of soil mulching compositions.

The invention relates to the chemistry of synthetic substances polymer in a mixture with organic and natural substances, such as for urban and agricultural purposes, or compositions for mulching different types of soils, lawns, parks and gardens.

Was formerly known such a composition of the mulch, which is used polyacrylamide, urea, lignosulfonate, potassium chloride and water in the following ratio, wt.%: polyacrylamide 0,25-0,75, lignosulfonate 0.5 to 1.5, urea, 0.4 to 0.8, potassium chloride 1-3, water - the rest (patent of Russia №2034899 C1, 1995, a class of the international classification of patents, C09K 17/00).

However, this patent did not use natural materials is a significant disadvantage. Nature provides many suitable materials, many mosses, different types of wood waste, bark, shavings, chips. In this case, different types of wood can be combined with different kinds of synthetic materials - polymers, their waste if they are harmless to the environment.

In the technical result of the invention is the use of numerous kinds of natural materials, that is, the extension of the range of compositions for mulching soils.

This result is achieved by the fact that the composition of the mulch, according to the invention, contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride, and ka is este natural supplements moss species Conocephalum and needles of larch Larix koreana, water, wt.%:

As variants invented the following compounds, which are changed (selected) important relations for moss and pine needles:

or

The composition prepared as follows.

These ingredients are subjected separately to grinding and after mixing in the aquatic environment.

the table below presents various examples of variants of the invention:

1. The composition of the mulch, characterized in that it contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural to the AVOK moss species Conocephalum and needles of larch Larix koreana, water in wt.%:

2. The composition of the mulch, characterized in that it contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives moss species Conocephalum and needles of larch Larix koreana, water, wt.%:

3. The composition of the mulch, characterized in that it contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives moss species Conocephalum and needles of larch Larix koreana, water, wt.%:
