Abstract

The invention provides a combined method and device for a variable-rate application of a soil heavy metal passivating agent, and relates to the technical field of passivating agent applications. The device comprises a soil near-ground sensing unit, a central control unit and a passivating agent variable-rate application unit which are connected in sequence; the soil near-ground sensing unit is used to collect reflection spectrum information and positioning information at the current position; the central control unit is used to generate and draw a heavy metal space distribution electrical signal in a target area according to the reflection spectrum information, the positioning information and preset geographic information; and the passivating agent variable-rate application unit is used toapply the passivating agent at a preset speed according to the heavy metal space distribution electrical signal. According to the embodiments provided by the invention, the heavy metal space distribution electrical signal in the target area can be quickly detected in real time, and the passivating agent is applied to soil on demand according to the heavy metal space distribution electrical signal; and the device realizes integration of monitoring and repair are, has a reasonable structure, and improves the passivation efficiency.

Description

technical field [0001] The invention relates to the technical field of passivating agent application, in particular to a combined method and device for variable application of soil heavy metal passivating agent. Background technique [0002] Food and food safety problems caused by heavy metal pollution are not uncommon. The form of heavy metals in soil affects their activity and bioavailability, and eventually enters animals and humans, endangering human health. Considering the relationship between its use and the actual balance of payments, farmland soils seldom use large-scale engineering investment for heavy metal restoration, and mostly use in-situ passivation agents, phytoremediation, or agricultural ecological restoration technologies for restoration. Passivating agents have attracted widespread attention due to their advantages of low cost, fast effect, simple operation, and no impact on crop production. They are considered to be one of the most effective methods for...
