Abstract

This invention relates to agriculture. The purpose of the invention is to improve the water-physical properties and durability of the substrate. For the cultivation of plants, a substrate based on a mineral or glass shafts is used. Cotton wool is made in the form of a pierced corrugated mat with a density of 50-150 kg / m with a content of 0.5-3 wt.% Hydrophilic substances. The moisture content of the substrate with the introduction of graphene substances is 66-90.5% by volume against 40-57% without hydrophilic substances. 2 tab.

Description

The invention relates to the manufacture of a substrate in the form of articles of mineral or glass wool and can be used for growing plants.

The aim of the invention is to improve the water-physical properties and the durability of the substrate.

Example. As samples for testing, mineral wool mats of a corrugated structure with a density of 0-150 kg / m, containing 0.5 and 3% of solid substances, and mineral wool plates on synthetic bonding horizontally layered structures with a density of 120-140 mg / m were taken. binder content (phenol alcohols) 5-6%.

To test these products for the possibility of using them as a substrate for growing plants, tomato seeds were sown on samples of sizes XOOx x 500 mm. Plants planted on the stitched mats of the corrugated structure developed normally and fruited, and the plants planted on mineral wool plates on a synthetic binder with a horizontally layered structure did not develop well, lagging behind the plants growing on the pierced mats died.

It is noticed that as a result of the impact of the nutrient solution: plates with a horizontally layered structure showed shrinkage by up to 40% in comparison with the piercing mats of the corrugated structure, which determined to a great extent the growth retardation and the death of plants.

Plants on pierced mats developed as follows.

The vigorous seeds of tomato varieties Miracle of the market dived 14 days later, 50 days after germination, they bloomed, after 15 days, fruits that developed normally developed. The first ripe fruit was obtained on the 130th day after germination. Shrinkage of the mats under the influence of the nutrient solution was not observed.

Examples of the implementation of the substrate boundary values of density, and hydrophilic substances are presented in Table. 1 and 2.

From tab. 1 shows that the proposed substrate with an equal density with the known one has an increased strength, which provides it with less shrinkage during operation. From the results presented in table. 2, it can be concluded that the substrate is hydrated with the introduction of 0.5–3.0 wt.% Hydrophilic substance into it.

Claims (1)

The results of the carried out works showed the possibility and economic expediency of using mineral wool pierced mats, the adaptability of their use: it is not necessary to remove harmful substances - phenolic alcohols, they have a slight shrinkage in comparison with the known ones. Invention Formula The substrate for growing plants based on mineral or glass wool, characterized in that, in order to improve the water-physical properties and durability of the substrate, mineral or glass wool is made in the form of a pierced corrugated mat with a density of 50-150 kg / m, containing , 5–3 wt.% Hydrographic in still with TV.
