Rapid screening and targeted regulation method for restrictive factors of polluted cultivated land

Abstract

The invention relates to a rapid screening and targeted regulation method for restrictive factors of a polluted cultivated land, which can determine restrictive factors influencing agricultural product standard exceeding according to soil monitoring data and agricultural product monitoring data and give each factor regulation and control quantity, is more conducive to making targeted decision-making measure suggestions through restrictive factor regulation and control target quantity determination, and waste of resources such as manpower and materials caused by unclear causes of existing pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural environment, and specifically relates to a method for rapid screening and targeted regulation of limiting factors in polluted cultivated land. Background technique [0002] The interaction between heavy metals and physical and chemical properties in soil is coupled with each other, which directly affects the enrichment and distribution of heavy metals in agricultural products. Clarifying the relationship between various factors in the soil and their impact on agricultural products is the focus and difficulty of current research in the field of agriculture. At present, most of the research on the main causes of agricultural products exceeding the standard is carried out around inputs such as pesticides and fertilizers, and the research objects on the impact of heavy metals in soil are mostly available heavy metals. [0003] The main problems in the above-mentioned technical methods are: (1) t...

Problems solved by technology

[0003] The main problems in the above-mentioned technical methods are: (1) the main factors affecting the over-standard of agricultural products, lack of comprehensive analysis of heavy metals and physical and chemical properties in the soil; (2) it is difficult to directly determine the main cause of over-standard agricultural products based on the existing soil testing data; (3) farmland Pollution prevention and crop quality and safety countermeasures lack pertinence, and resources such as human capital are excessively invested
