Key innovations
The innovation of this green technology lies in its independent intellectual property chemicals and the three-dimensional management strategy of "soil passivation + foliar resistance control". By reducing the activity of heavy metals (especially cadmium) in the soil and improving crop resistance, the cadmium content of agricultural products has been significantly reduced by more than 50%, and the effective cadmium content of cultivated land has been reduced by more than 15%.
Potential economic benefits
Ensure the safe use of contaminated cultivated land, improve the quality and market competitiveness of agricultural products (such as rice), increase agricultural returns, and avoid land abandonment.
Potential climate benefits
Improving soil health and increasing soil organic matter content will help soil carbon sequestration and indirectly reduce greenhouse gas emissions. At the same time, we will ensure the use of cultivated land and avoid carbon emissions caused by land reclamation.

Solution details

1. scope of application

Environmentally friendly, agricultural products that can be used on the ground.

2. Brief description of technology

Principle: It is mainly to use our company's pharmaceuticals with independent intellectual property rights as carriers to inactivate heavy metals in soil and reduce their activity. We will exert three-dimensional efforts from soil to crops to ensure the safe use of heavy metal-contaminated cultivated land, improve crop resistance and reduce crop resistance. Absorption of heavy metals. Function: Reduce heavy metal cadmium in cultivated soil. Process: sampling and testing-calculating the dosage of the agent-spreading the agent-plowing and stirring-irrigation and curing-foliar resistance control.

3. technical information

Soil conditioner: available calcium (calculated as CaO)/%≥34, etc.; foliar inhibitor: silicon (calculated as Si) content/g/L≥80, etc.

4. comprehensive benefits

Compared with before using this technology, using this technology can reduce the available cadmium content in cultivated soil by more than 15%, and the cadmium content in rice by more than 50%.
