RU2473658C1 - Composition of mulch cover (versions) - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: composition of mulch cover which is characterised by the fact that it contains lignosulphonate, carbamide, NA-carboxymethyl cellulose, potassium chloride; and moss of species Moerckia and needles of juniper Juniperus virginiana "Erecta" as natural supplements; and water in the following ratio, wt %: lignosulphonate 0.1-0.4, carbamide 0.2-0.6, NA-carboxymethyl cellulose 0.3-0.4, potassium chloride 1-3, moss of species Moerckia 10-15, needles of juniper Juniperus virginiana "Erecta" 8-9, water - the rest. And also other versions of compositions of polymer-natural mulch cover are claimed.

EFFECT: expanding of range of compositions for mulching of soil.

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, carbamide 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 juniper Juniperus virginiana 'Erecta', 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 juniper needles Juniperus virginiana 'Erecta' 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 juniper needles Juniperus virginiana 'Erecta' 9.1-9.5

or

moss species Moerckia 10-15 juniper needles Juniperus virginiana 'Erecta' 9.8-11

The composition is prepared as follows.

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