Mulching composition (versions)

FIELD: chemistry.

SUBSTANCE: mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Pellia endiviifolia moss and Larix middendorffii 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, Pellia endiviifolia moss 10-15, Larix middendorffii larch needles 8-9, water - the balance. Moss and larch needles can also be taken in the following ratios, wt %: Pellia endiviifolia moss - 10-15, Larix middendorffii larch needles- 9.1-9.5; or Pellia endiviifolia moss - 10-15, Larix middendorffii larch needles - 9.8-11.

EFFECT: wider range of soil mulching compositions owing to use of natural materials; improved environmental friendliness of mulching compositions.

The invention relates to the chemistry of synthetic substances polymer in a mixture with organic and natural substances, for example, 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, SC 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 to the availability of natural additives moss species of Pellia endiviifolia and needles of larch Larix middendorffii, water in the following, 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 the grinding and the Les are mixed in the aquatic environment.

The table shows various examples of variants of the invention:

1. The composition of the mulch, characterized in that it contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chlorine the East, and, as natural additives moss species of Pellia endiviifolia and needles of larch Larix middendorffii, water, 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 of Pellia endiviifolia and needles of larch Larix middendorffii, 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 of Pellia endiviifolia and needles of larch Larix middendorffii, water, wt.%:
