2 interpretations of result
2.1 different modifying agents match somebody with somebody the leaching effect applied
The lower sepage electrical conductivity situation of 1 different modifying agents of table processing
Different modifying agents are shown with the lower sepage electrical conductivity situation of processing is applied in table 1, respectively handle relative comparison processing table
Bright, modifying agent of the present invention is variant with applying the lower sepage electrical conductivity highest of processing, between 42.2-43.1ms/cm；Ureasulfuric acid
Class modifying agent takes second place, between 35.3-36.3ms/cm；Polyacrylic acid is minimum, between 20.8-32.3ms/cm.This says
Leaching effect of the present invention is best under bright different modifying agent processing, and second especially of the invention optimal with processing is applied, and reaches
43.1ms/cm, relative comparison processing, relative changing value 12ms/cm；Polyacrylic modifying agent the third effect is most
Difference, lower sepage electrical conductivity are only 28.8ms/cm, and relative comparison processing, relative changing value is -2.3ms/cm.
2.2 different modifying agents match somebody with somebody the influence applied to soil pH value
2 different modifying agents of table are with different soil pH value situation under processing of applying
Different modifying agents are shown with the lower different soil pH value situation of processing is applied in table 2, respectively handle relative comparison processing table
It is bright, modifying agent of the present invention it is variant with apply processing under each soil layer pH value be below control treatment, sulfuric acid ureas modifying agent effect is not
Substantially；The C1 of polyacrylic acid modifying agent is also below control treatment.This illustrates the influence present invention to pH under different modifying agent processing
Effect is best, and A3 especially of the present invention is optimal with processing is applied；Polyacrylic modifying agent C1 effects are preferable.
2.3 different modifying agents match somebody with somebody the influence applied to soil total salt
3 different modifying agents of table, which are matched somebody with somebody, applies each soil layer electrical conductivity situation under processing
Different modifying agents are shown with each soil layer electrical conductivity situation under processing of applying in table 3, each to handle relative comparison processing table
Bright, outside sulfuric acid urea B1 modifying agents, other modifying agents have obvious effect.A3 effects are best in modifying agent wherein of the present invention,
B2 effects are best in ureasulfuric acid modifying agent, and C3 effects are best in polyacrylic acid modifying agent.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
Some variations that some of which part may be made are embodied the present invention principle, belong to protection scope of the present invention it
It is interior.
