RU2473610C1 - Mulching composition - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry, agricultural industry and forestry, for example, for mulching different types of soil, lawn and parking areas. The mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and water. The composition contains natural additives in form of Moerckia moss and Picea engelmanni fir needles, taken in different amounts in different versions of the invention.

EFFECT: wider range of soil mulching compositions.

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 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, 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 spruce Picea engelmanni, water in 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 needles spruce Picea engelmanni 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 needles spruce Picea engelmanni 9.1-9.5

or

moss species Moerckia 10-15 needles spruce Picea engelmanni 9.8-11

or

moss species Moerckia 15,5-17 needles spruce Picea engelmanni 8-9

or

moss species Moerckia 17.8-18 needles spruce Picea engelmanni 8-9

or

moss species Moerckia 17.8-18 needles spruce Picea engelmanni 9.8-10

The composition is prepared as follows.

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