A kind of determination method and device of soil management plant

Abstract

The invention discloses a method and a device for determining soil management plants. The method includes: acquiring environmental indicators of a target area, wherein the environmental indicators at least include climate indicators and soil indicators of the target area; inputting the environmental indicators of the target area into a plant prediction model; acquiring the governance plants corresponding to the target area output by the plant prediction model , the treatment plants meet the climate indicators of the target area, and can absorb the excessive heavy metals recorded in the soil indicators. By adopting the method provided by the present invention, the conditions of soil restoration by different plants under different environmental factors are predicted by integrating multiple indicators such as climate and soil in the target area, and soil restoration plants are determined according to the prediction results.

Description

technical field [0001] The invention relates to the field of plant ecological environment, in particular to a method and a device for determining plants for soil treatment. Background technique [0002] my country's soil arsenic pollution is a serious problem. Excessive arsenic in these soils enters the human body along the food chain and is harmful to health. Phytoremediation is a green, sustainable and economical soil remediation technology. The hyperaccumulator plants used in this technology are capable of hyperaccumulating specific metal elements and are protected from metal element poisoning. The actual application process of phytoremediation is affected by many aspects such as climate and soil in the external environment. Even the concentration of heavy metals enriched by the same plant in different locations varies greatly. This makes further promotion of this technology difficult to unify and standardize. In this regard, establishing a prediction model to predict...

However, most of the studies done so far are pot experiments in the laboratory environment, which may not be able to simulate the conditions in the field environment, especially climate factors such as temperature and precipitation are often not included in the laboratory environment.

In addition, the variable factors controlled by different studies are relatively isolated, and phytoremediation in regions with different climate characteristics is rarely integrated and analyzed, which still has a certain gap with the multi-faceted influencing factors that may exist in the external environment of the phytoremediation process.
