Growing culture medium for ecological remediation and preparation method thereof

Abstract

The invention discloses a growing culture medium for ecological remediation and a preparation method thereof. The growing culture medium comprises the following raw materials in parts by weight: 5-12 parts of lutein ester, 11-19 parts of lignocellulose, 7-15 parts of algin, 28-36 parts of straw powder, 15-25 parts of tartaric acid, 20-30 parts of variegated-leaf begonia and 1-5 parts of propyl acetate. The preparation method comprises the following steps: mixing the variegated-leaf begonia, the tartaric acid and deionized water, heating, performing ultrasonic treatment, mixing with the lignocellulose and the propyl acetate, heating, and performing ultrasonic treatment to obtain a mixture B; adding deionized water and the tartaric acid into the straw powder, heating, and performing ultrasonic treatment to obtain a mixture C; mixing the mixture B and the mixture C, adding the remaining materials, heating, and stirring till a dry state to obtain the growing culture medium. The growing culture medium can effectively improve soil, play water-retaining and fertilizer-retaining roles, improves the growth environment for plants, can provide nutrients immediately, can activate heavy metals which cannot be dissociated from the soil so as to promote heavy metal absorption of the plants, and can be applied to the fields of ecological remediation for a mining area, heavy metal-contaminated land remediation, slope remediation and the like.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation, in particular to a growth cultivation substrate for ecological restoration and a preparation method thereof. Background technique [0002] The irrational development and utilization of human beings has caused the destruction of natural ecological environments such as forests and grasslands, thereby deteriorating the living conditions of humans, animals, and plants; such as: soil erosion, land desertification, soil salinization, and biodiversity reduction, etc. Wait. The consequences of environmental damage often take a long time to recover, and some are even irreversible. The deteriorating ecological environment has attracted more and more attention from all countries. More and more people are beginning to realize that human beings should constantly update their concepts and adjust their behavior at any time in order to realize the harmonious coexistence of human beings and ...

AI Technical Summary

Problems solved by technology

The existing remediation methods are poor in effect, and they are all specially aimed at a certain pollution situation. The scope of application is narrow, and they cannot achieve sustainable and low-maintenance effects. The plants grow slowly and the biomass is small.
