A method for rapid screening and targeted regulation of limiting factors in polluted cultivated land

Abstract

This application relates to a method for rapid screening and targeted regulation of restrictive factors in polluted cultivated land. Based on soil monitoring data and agricultural product monitoring data, the restrictive factors that affect agricultural products exceeding the standard can be determined and the regulation amount of each factor is given. Through the restrictive factors Determining the amount of control targets is more conducive to the formulation of targeted decision-making measures and suggestions, and reduces the waste of resources such as human resources and materials caused by the unclear causes of existing pollution.

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
