Mulching composition (versions). RU patent 2513171.

FIELD: chemistry.

SUBSTANCE: mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride, natural additives - Tetraphidopsida moss and Larix maritima 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, Tetraphidopsida moss 10-15, Larix maritime 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 mixed with organic and natural substances, for example, for municipal and agricultural purposes or compositions for mulching the various soil types, lawns, gardening of territories.

Previously known such a composition of the mulch, which was used polyacrylamide, carbamide, lignosulfonate, potassium chloride and water, in the following ratio, mass%: polyacrylamide 0,25-0,75, lignosulfonate 0,5-1,5, carbamide 0,4-0,8, potassium chloride 1-3, water - the rest (patent of Russia №2034899 C1, 1995, the class of the international classification of patents, C09K 17/00).

But such a patent is not used natural materials is a significant disadvantage. Nature provides many suitable materials - many of 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 such as polymers, waste - if they are harmless to the environment.

In my invention technical result is the use of multiple types of natural materials, that is expanding Arsenal of compositions for mulching of soil.

This result is achieved by the fact that the composition of the mulch, according to the invention, contains lignosulfonate, carbamide, PA-the carboxymethyl cellulose, potassium chloride, and as a natural additives moss species Tetraphidopsida and needles larch Larix maritima, water footprint. wt.%:

lignosulfonate

PA-carboxymethylcellulose

potassium chloride

moss species Tetraphidopsida

pine larch Larix maritima

As options invented following compositions change (selected) important ratios for moss and pine needles:

moss species Tetraphidopsida

pine larch Larix maritima

from 9.1 to 9.5

moss species Tetraphidopsida

pine larch Larix maritima

The composition is prepared as follows.

These ingredients are subjected individually ground and, after mixing in the water environment.

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