Embodiment 1

[0029] The preparation method of soil remediation agent of the present invention is as follows:

[0030] 1) Weigh Radix Isatidis, Dandelion, and Bupleurum root, crush them, add 15 times the weight of water to soak for 2 hours, heat to 100°C, keep the temperature for 30 minutes, filter, then add 8 times the weight of water, heat at 100°C, keep the temperature for 20 minutes, filter, and then Add 6 times the weight of water, heat at 100°C, keep the temperature for 10 minutes, filter, and keep the liquid in each filter;

[0031] 2) Mix the amino acid liquid with the liquid in step 1), slowly add polyacrylamide into the mixed liquid, stir in the enamel reaction kettle at a speed of 120r / min for 5 minutes, and let it stand for 30 minutes to obtain a gelatinous liquid;

[0032] 3) mixing rhamnolipid, sucrose ester and potassium fulvic acid and stirring evenly;

[0033] 4) Add the mixture in step 3) to the gelatinous liquid in step 2), and stir for 10 minutes;

[0034] 5) Quantitat...

Abstract

The invention relates to a soil restoration agent containing a biological surface active material. The soil restoration agent is obtained by combining bio-surfactant rhamnolipid, sucrose ester, humic acid and amino acids and adding Chinese herbal medicinal ingredients such as indigowoad root and herba taraxaci which have a sterilization function, the soil restoration agent has functions of improving soil granular structure and soil property, enhancing soil fertility, restraining soil-borne diseases and improving crop quality, pesticide residues and passivated heavy metals can also be effectively reduced, all components of the soil restoration agent are completely biodegradable, and the soil restoration agent does not lead to secondary pollution to the environment and belongs to green environment-friendly products.

Description

technical field [0001] The invention relates to the field of fertilizers and soil conditioners, in particular to a soil repair agent containing biological surface active substances and its preparation method and application. Background technique [0002] Nearly one-fifth of China's existing arable land is polluted to varying degrees. Polluted soil will lead to crop yield reduction, and may even cause pollutants in agricultural products to exceed the standard, thereby endangering human health. In order to effectively strengthen the prevention and control of soil pollution and gradually improve the quality of the soil environment, the State Council issued the "Action Plan for the Prevention and Control of Soil Pollution" on May 28, 2016. Soil is an important material basis for sustainable economic and social development, and an indispensable and difficult-to-regenerate natural resource. Therefore, the prevention of soil pollution and the remediation of contaminated soil must b...
