Embodiment Construction
[0031] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.
[0032] The invention provides a rice rhizosphere effective state heavy metal control system, comprising figure 1 The simulated paddy field setup shown as well as figure 2 The paddy field water refinement management device shown, the simulated paddy field device is used to quantify the soil Eh and pH control range when the rhizosphere available heavy metal content is the lowest, and construct the quantitative relationship between rice rhizosphere Eh, pH and available heavy metal content , to calculate the required Eh and pH range intervals during the rice growth period. The paddy field water fine management device is used for fine management of field water according to the constructed quantitative relationship between rice rhizosphere Eh, pH and available heavy metal content.
