Soil remediation liquid

Abstract

The invention discloses a soil remediation liquid including, by mass, 8-10 parts of organic spirulina powder, 8-10 parts of talcum powder, 5-8 parts of NaHCO3, 16-22 parts of low carbon bacillus subtilis, and 30-50 parts of distilled water. The soil remediation liquid increases water and fertilizer retention capability of soil and makes soil more and more fertile as planting crops year after year.The soil remediation liquid also can promote reproduction of beneficial organisms, such as earthworms, in soil, can enhance water permeation and retention and breathability and can promote aggregation, can reduce use amounts of chemical fertilizers and pesticides year by year; after application for 3-5 years, the ecologic, physical and chemical properties of soil are completely modified, thus achieving zero tillage. The soil remediation liquid has large scope and high speed of reducing residual pesticide, can degrade toxic chemical components, such as organic phosphorus, organic chlorine, organic nitrogen and herbicides, and turns the components into harmless substances.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil restoration liquid. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants, and its thickness is generally about 2m. Soil not only provides mechanical support for plant growth, but also provides fertility elements such as water, fertilizer, air, and heat for plant growth and development. 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 scattered into the envi...

Problems solved by technology

[0004] At present, due to the pursuit of high yield of food, quality, quality and taste are ignored, and a large amount of chemical fertilizers and pesticides are used, which pollutes soil, water and fertilizers, promotes the growth of plant structure and growth patterns, destroys plant nutrients, and reduces plant quality. The quality contains chemical fertilizers and pesticide residues with an exceeding rate of 20-30%, and the rate of soil heavy metals exceeding the standard reaches 15.1%. 30% of the cultivated land has been polluted by heavy metals, and 50% of the cultivated land in most parts of my country has suffered from heavy metals such as cadmium, arsenic, mercury, chromium and petroleum.
