Problems solved by technology

However, the soil remediation agent in the prior art has poor remediation effect, has secondary pollution to the soil, and has only a single function, but has no insect-proof, anti-bacteria and fertilizer-enhancing effects.
[0004] The Chinese patent application with the application number 20111041314.5 discloses a method for soil remediation using cadmium-resistant tobacco varieties, chitosan solution and microorganisms that activate heavy metals in the soil to act together, but because it is based on the cooperation with crop varieties, it is used Narrower range of crops with less repeatability

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil restoration agent and a preparation method thereof. Background technique [0002] In recent years, with my country's economic development and urban layout adjustment, many chemical fertilizer factories, pesticide factories, chemical factories and other enterprises that discharge a large amount of organic waste have been relocated from the city center, and a large number of former industries that have been abandoned, idle or no longer used have emerged. and commercial land. Most of these lands have seriously polluted the soil due to the entry of a large amount of chemicals. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, and the microbial activities will be inhibited; Air, water, and food chains are enriched into human and animal bodies, t...
