Abstract

The invention discloses a microorganism-containing composite soil remediation agent which comprises a composite microbial agent and composite powder, wherein the composite microbial agent comprises bacillus, sphingobacterium, pseudomonas and aspergillus oryzae, and the composite powder comprises diatomite, aquatic floaters, livestock and poultry manure, bagasse and corn straw. The composite powder is prepared from the following components in parts by weight: 20 to 40 parts of diatomite, 10 to 20 parts of aquatic floaters, 5 to 10 parts of livestock and poultry manure, 3 to 10 parts of bagasse and 20 to 30 parts of corn straws. Various production wastes obtained by agricultural production are adopted as raw materials, the manufacturing cost can be remarkably reduced, and due to the adoption of natural raw materials, secondary damage to soil is avoided, the remediation effect is excellent, and the soil remediation agent is more natural and environmentally friendly.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to a composite soil restoration agent containing microorganisms. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants. Its thickness is generally about 2m. The soil not only provides mechanical support for plant growth, but also provides water, fertilizer, air, heat, etc. for plant growth and development. Fertility factor. In recent years, due to the rapid growth of population and the rapid development of industry, solid wastes are continuously stacked and dumped on the soil surface, harmful waste water is continuously infiltrated into the soil, exhaust gas emitted by automobiles, harmful gases and floating dust in the atmosphere are constantly falling into the soil with rain. The improvement of the agricultural chemical level has caused a large amount of chemical fertilizers and pesticides to be scatt...
