Problems solved by technology

Although manganese, copper, zinc and other heavy metals are trace elements needed for life activities, most heavy metals such as mercury, lead, cadmium, etc. are not necessary for life activities, and all heavy metals are toxic to the human body if they exceed a certain concentration

Embodiment 1

[0027] A method for carrying out soil restoration to heavy metal cadmium pollution, comprising the following steps:

[0028] A. Spread special fertilizer for soil restoration on the polluted land and plow it;

[0029] B, plant fast-growing eucalyptus according to row spacing 2.8 meters;

[0030] C, when the fast-growing eucalyptus grows to 1.8-2 meters, every two rows of eucalyptus trees are planted as vines;

[0031] D, when the liana reaches the transplanting condition, transplant and replant the liana;

[0032] E. After the fast-growing eucalyptus reaches the harvesting conditions, the harvesting is carried out;

[0033] F. After the fast-growing eucalyptus is harvested, the soil is tested. After the cadmium content is reduced to the standard conditions for planting food crops, food crops can be planted, otherwise the fast-growing eucalyptus can be planted.

[0034] In the step A, the special fertilizer for soil restoration contains the following main components in weigh...

Embodiment 3

[0046] A kind of method that soil remediation is carried out to heavy metal cadmium pollution, comprises the following steps:

[0047] A. Spread special fertilizer for soil restoration on the polluted land and plow it;

[0048] B, plant fast-growing eucalyptus according to row spacing 3 meters;

[0049] C, when the fast-growing eucalyptus grows to 1.8-2 meters, every two rows of eucalyptus trees are planted as vines;

[0050] D, when the liana reaches the transplanting condition, transplant and replant the liana;

[0051] E. After the fast-growing eucalyptus reaches the harvesting conditions, the harvesting is carried out;

[0052] F. After the fast-growing eucalyptus is harvested, the soil is tested. After the cadmium content is reduced to the standard conditions for planting food crops, food crops can be planted, otherwise the fast-growing eucalyptus can be planted.

[0053] In the step A, the special fertilizer for soil repair contains the following main components in we...

Abstract

The invention discloses a method for carrying out soil remediation on heavy metal cadmium-contaminated soil. According to the method, a special fertilizer for soil remediation is dispersed into the soil at first, and then fast-growing eucalyptus is planted; the special fertilizer for soil remediation plays a main role of providing the fertilizer for the growth of the fast-growing eucalyptus and has a good collection function for heavy metal cadmium in the soil, so that absorbing of the fast-growing eucalyptus is facilitated; a control effect on grubs can be remarkably improved through adding coffee grounds into the special fertilizer for soil remediation; the generated fast-growing eucalyptus is mainly applied to furniture or papermaking, and free from causing harm to human body or livestock as a food; vines are planted at intervals, so that the economic value per unit area can be increased, and moreover, the root systems of the vines are shallow relative to the root systems of the fast-growing eucalyptus, and the vines are mutually cooperated with the fast-growing eucalyptus with the deep root systems, so that cadmium in the soil is much easily and rapidly absorbed, and the remediation speed for the soil is increased; and in conclusion, the soil remediation method disclosed by the invention is good in remediation effect and remarkable in economical benefit.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a method for soil remediation of heavy metal cadmium pollution. Background technique [0002] Heavy metals refer to metals with a specific gravity greater than 5 (generally referring to metals with a density greater than 4.5 grams per cubic centimeter). There are about 45 species, generally belonging to transitional elements. Such as copper, lead, zinc, iron, cobalt, nickel, manganese, cadmium, mercury, tungsten, molybdenum, gold, silver, etc. Although heavy metals such as manganese, copper, and zinc are trace elements needed for life activities, most heavy metals such as mercury, lead, and cadmium are not necessary for life activities, and all heavy metals are toxic to the human body if they exceed a certain concentration. [0003] For example, the clinical manifestations of mercury poisoning are: general symptoms are headache, dizziness, fatigue, and fever. Symptoms...
