In summary, as can be seen from table 1, the average yield increase rate of the rice in examples 1 to 5 reaches 17.98%, and the yield increase rate of the rice in the comparative example reaches 15.9%, which indicates that the soil remediation improver is obviously improved on the soil, meanwhile, the comparative example only applies the soil remediation improver, and the example applies the soil remediation improver after applying the soil remediation improver auxiliary solution on the soil in advance, which is improved by 2.08% compared with the comparative example, which indicates that the application of the soil remediation auxiliary solution is beneficial to the propagation of beneficial microorganisms, efficiently decomposes the refractory organic matters in the soil, and improves the fertilizer quality of the soil;
as can be seen from Table 2, the soil remediation improver has a high heavy metal removal rate, and can further improve the heavy metal removal rate by being supplemented with the soil remediation improver auxiliary liquid, so that the soil improvement effect is good.
