Example Embodiment

[0036] Example 1:

[0037] First, pulverize calcium oxide, pass through a 100-mesh sieve, and set aside;

[0038] Next, take 60 parts of calcium oxide powder by weight, 36 parts of humic acid, 2 parts of abscisic acid, and 2 parts of trace element raw materials in proportion to scientific compatibility, mix them evenly, put them in a fermenter for quick-ripening fermentation, and decompose into a modifier. Raw material combination, spare;

[0039] Third, dry, pulverize and sieve the combination of modifier raw materials, the particle size is less than 0.18mm, and it is ready for use;

[0040] Fourth, according to the conventional extrusion method for the production of granulated organic fertilizer, granulation is carried out, and then it is packaged.

Abstract

The invention discloses an ecological improver for heavy metal pollution of soil. The ecological improver is prepared by mixing, by weight, 50-70 parts of calcium oxide, 26-46 parts of humic acid, 1-3 parts of abscisic acid and 1-3 parts of microelements, decomposing and fermenting the mixture and granulating the fermented mixture, has the advantages of effectively regulating the PH value of the soil, significantly increasing organic matter in the soil, supplementing abscisic acid and the microelements in the soil, achieving the obvious repairing effect after being applied to the soil polluted by heavy metals and the like and can be not only used for heavy metal pollution repairing and ecological improving of the paddy farmland soil in the south of China but also used for heavy metal pollution repairing and ecological improving of the dry soil farmland in the south of China. The invention further discloses a preparation method of the ecological improver for heavy metal pollution of the soil.

Description

technical field [0001] The invention relates to the technical field of cultivated land restoration, in particular to an ecological improver for soil heavy metal pollution and a preparation method thereof. Background technique [0002] In April 2014, the Ministry of Environmental Protection and the Ministry of Land and Resources jointly issued the first national survey report on soil pollution. The overall situation of the national soil environment is not optimistic. Some areas have serious soil pollution, and the quality of cultivated land soil environment is worrying. Among the soils of different land use types, the point exceeding standard rate of cultivated land soil was the highest, which was 19.4%. Among them, heavy metal pollutants are mainly mercury, arsenic, copper, lead, chromium, zinc, and nickel, which seriously pollute agricultural land and agricultural products, causing heavy metal residues in agricultural products in these places to exceed the standard, and lea...
