The nutrient geotextile is a functional non-woven geotextile specially developed for a plant ecological concrete slope protection material, the non-woven fabric can be uniformly laid at the bottom of plant ecological concrete, while the reverse filtration performance of the common non-woven geotextile is kept, a compound fertilizer in the non-woven fabric can be slowly decomposed, long-term nutrients are provided for plants on the plant ecological concrete, plant root growth nutrients are provided by utilizing the plant fertilizer tendency characteristic, the roots of the plants are promoted to be quickly rooted to the soil, the problem of insufficient slow release fertilizer in a filling material caused by limited space in gaps of the plant ecological concrete is solved, and the survival rate of the plants is improved.
Disclosure of Invention
The invention provides a nutrient geotextile, which solves the problem of poor growth environment caused by limited space in a concrete gap of plants, improves the survival rate of the plants, improves the growth environment of the plants, increases the microbial activity of soil, provides sufficient nutrient conditions for the healthy growth of the plants and has very important significance for realizing agricultural sustainable development.
The invention relates to a nutrient geotextile, which comprises a woven fabric layer, a nutrient layer and a non-woven fabric layer, wherein the nutrient layer comprises the following raw materials in parts by weight: 20-30 parts of modified bentonite, 5-10 parts of an active carbon source, 8-15 parts of an active nitrogen source, 5-10 parts of EM (effective microorganism) strain and 1-5 parts of bean dregs.
Preferably, the raw materials of the nutrition layer are as follows: 25 parts of modified bentonite, 10 parts of activated carbon source, 8 parts of activated nitrogen source, 6 parts of EM strain and 3 parts of bean dregs.
The preparation process of the nutrition layer comprises the following steps:
(1) weighing the raw materials of the nutrition layer according to the proportion for later use;
(2) uniformly mixing bentonite, silver nitrate solution and sodium dodecyl benzene sulfonate, stirring for 2-3h at room temperature, filtering, and drying to obtain a solid material; then, carrying out gradient roasting on the solid material to obtain modified bentonite;
(3) and adding the bean dregs, the activated carbon source, the activated nitrogen source and the EM strain into the modified bentonite in sequence, and mixing uniformly to obtain the nutrient layer.
The mass volume ratio of the bentonite to the silver nitrate solution is 0.1-0.5g/20 ml.
The mass ratio of the bentonite to the sodium dodecyl benzene sulfonate is 1: 0.01-0.05.
Before gradient roasting, the solid material is firstly added into a planetary ball mill for grinding and crushing, is sieved by a 200-mesh sieve, is then put into a muffle furnace to be heated to 300 ℃ at the speed of 30 ℃/min for 2h, is finally heated to 400 ℃ at the speed of 10 ℃/min for 1h, is taken out of the furnace for cooling after being kept warm for 1h, and the material is obtained.
In the invention, silver nitrate solution is used for modification, so that ions exchange is carried out between silver ions with low electricity price and large radius and cations in a bentonite layer, on one hand, layered bentonite can be peeled and dispersed into thinner single pieces with the assistance of sodium dodecyl benzene sulfonate, the specific surface area is larger, and more nitrogen sources, carbon sources and EM strains can be adsorbed in the later period. The method mainly caters to the characteristic that the bentonite has different surface areas when being roasted at different temperatures by adopting gradient roasting, so that the surface area of the bentonite is gradually increased, the bentonite can lose surface water firstly when being heated, water and impurities in gaps are adsorbed between layers, and the adsorption of a nitrogen source, a carbon source and EM strains is enhanced. In the invention, silver nitrate can be used for modifying bentonite on one hand and can be used as a partial nitrogen source on the other hand to provide nutrition for the growth and the propagation of EM strains. Because silver ions have the bacteriostatic action, the proportion of silver nitrate is not too much, and the mass-volume ratio of bentonite to silver nitrate solution is 0.1-0.5g/20ml, so that the bentonite can be modified and harmoniously co-located with EM strains.
The nitrogen source adopted in the invention is urea, and the carbon source is glucose. Glucose is a monosaccharide, and its addition provides a nutrient guarantee to the microorganisms, thereby promoting the mass propagation of the microorganisms. Urea is a biological nitrogen, and the addition of urea can prolong the activity of the microorganisms.
In the invention, the introduction of EM strain can rapidly decompose organic matters in soil by using a plurality of microorganisms which form group operation and group operation, thereby killing harmful bacteria, increasing the activity of soil microorganisms and providing sufficient nutrition for the healthy growth of plants. The EM strain can utilize protein, various sugars and starch in the bean dregs to rapidly decompose tryptophan to form indole, and can stimulate plant roots to promote plant growth.
In conclusion, the bentonite is modified, and EM strains and the like are introduced to form a nutrition layer together, so that the bentonite can fully exert an adsorption effect, adsorb more nitrogen sources, carbon sources and EM strains, further improve the living environment of plants in concrete gaps, and improve the survival rate of the plants.
