Imperata cylindrica Beauv growth liquid applied to soil restoration in mining area, and preparation method thereof

Abstract

The invention discloses an Imperata cylindrica Beauv growth liquid applied to soil restoration in a mining area, and a preparation method thereof. The Imperata cylindrica Beauv growth liquid comprisesa plant decayed solution, hydroxyethyl cellulose, triethyl citrate, ammonium carbonate and potassium sulfate. Plants are treated by a specific means, enzymatic hydrolysis and fermentation are carriedout to obtain the plant decayed solution being suitable for growing roots of Imperata cylindrica Beauv and stimulating the roots of Imperata cylindrica Beauv, the hydroxyethyl cellulose which is highly viscous and easily soluble in water is added, and the triethyl citrate is a strong thickener and increases the viscosity of the hydroxyethyl cellulose, so the Imperata cylindrica Beauv growth liquid forms a protective film on the outer layer of the roots of Imperata cylindrica Beauv, can maintain the relative environmental stability of the roots, and can ensure the passing of water molecules without affecting the growth of the roots due to its hydrophilicity. The Imperata cylindrica Beauv growth liquid can promote the good growth of Imperata cylindrica Beauv in the mining area especially the seriously polluted mining area, and plays a great role in environmental protection and soil restoration.

Description

technical field [0001] The invention relates to a growth liquid of imperata imperata applied to soil restoration in mining areas and a preparation method thereof, belonging to the technical field of environmental protection. Background technique [0002] Imperata cylindrica (scientific name: Imperata cylindrica (L.) Beauv.) is a perennial herb of Gramineae and Imperata genus, with erect stems, up to 80 cm in height, and glabrous nodes. Leaf sheaths gathered at culm base, ligule membranous, culm leaves narrow and linear, usually involute, apex acuminate and spiny, lower part narrower, hard, base pilose. The panicle is dense, the first lemma is ovate-lanceolate, the second lemma is nearly equal to the inner lemma, ovoid, with teeth and cilia at the top; the style is slender, purple-black, the caryopsis is elliptic, and the flowering and fruiting stage April-June. [0003] Imperata has a strong root system, which can firm the soil and has a good protective effect on the soil....

AI Technical Summary

Problems solved by technology

[0004] In view of the fast growth and deep rooting of Imperata imperata, it has a great protective effect on the soil, and can change the local preparation environment, promote the growth of other plants, and form a good ecological environment. At present, the soil in most mining areas in China is seriously polluted , especially excessive metal ions lead to serious damage to the preparation. Based on the above problems, the present invention develops a growth solution, which can promote the growth of Imperata coronata in the mining area, improve the environment of the mining area, and repair the soil.
