FR2630291A1 - Growth medium for young seedlings based on ligneous components and polymerised water - Google Patents

Abstract

The present invention relates to an inert growth medium for seeds and young seedlings of any plant species. The product which acts as growth medium is characterised in that it consists of a mixture of polymerised water and of wood fibre, that it possesses a hygrometric constant, that it can be laden with nutrient components, that it leads to accelerated growth of the plant, that it slows down the evaporation of water and of the nutrient components, and that it can be packaged in any form.

BhSE OF ELE} ZOOTES WOOD AND WATER P0LYYR: SEE the present invention relates to a product serving as an inert culture medium for seeds and young plants of any plant species.

It is known that wood fibers of various species are used as a culture medium to promote better development of the system.

root of young plants of various plant species.

However, the use of such wood fibers has significant drawbacks, in particular linked to the absence of a hygrometric and nutritive constant in the culture support. These absence of a constant have a negative effect on plant growth because they slow down said growth and correlatively increase the susceptibility to diseases of young plants.

The present invention aims to remedy such drawbacks by providing young plants with a perfectly adapted growth medium. The new product is characterized in that the wood fibers are incorporated in polymerized and crosslinked water of adequate molecular weight and fillers. differentiated ionic.

The constant humidity is due to the polymerization of water. The mixture of polymerized water with wood fiber leads to an increase in ionic exchanges and therefore a better distribution of fertilization.

The growth vitamins and amino acids are introduced, at the time of manufacture, into the mixture of polymerized water and wood fiber. The anionic and cationic components used for fertilization are stored in ionic form. The amount of stored quantity depends on the rate of polymerization and crosslinking of the water.

The product according to the invention avoids any excess supply of nutrients, because the latter will not be absorbed by the medium because the rate of retention of nutrients is linked, during the manufacture of the product serving as a culture medium, to the rate water polymerization and crosslinking
The aeration of the product according to the invention remains constant during use because the polymerized water is introduced to the heart of the vegetable fiber.

The faster growth of the young plants results from the regular distribution of the nutritive matters. The absorption by the root system of the plant of all the nutritive elements occurs in an ideal way because the said root system works in osmosis with the ionic exchanges of the product serving as a culture medium. Nutrition is therefore ideally distributed to plants according to their needs.

In addition, the evaporation of water and nutrients is considerably slowed down by the absorption (retention) capacity of the polymerized and crosslinked water.

The product according to the invention can be packaged in various forms to meet the wishes of the customers.

By way of nonlimiting example, there will be presented photographs showing an embodiment of the present invention and clearly demonstrating the improvement brought by the invention compared to the conventional culture mode medium consisting of wood fibers.

Illustration No. 1 shows two verbena plants with, in the left cup a two-month plant, the growth medium of which is the product according to the invention; the right cup showing a two-month verbena plant, the growth medium is a wood fiber substrate conventionally used.

Illustration No 2 shows six pots: the left pots present from top to bottom a fuchsia plant, a verbena plant, a coleus plant.

These plants are two months old and have been cultivated in a wood fiber medium conventionally used.

The pots on the right show, from top to bottom, a fuchsia plant, a verbena plant, a seedling plant. These two-month-old plants were cultivated in the product serving as a culture medium according to the invention.

Note the important difference in the development of the leaf system depending on the growing medium used.

The product according to the invention can be used with all kinds of young plants and will therefore particularly attract the attention of the horticultural industry, taking into account the added productivity and the rapidity of growth offered.
