Soil improving agent and preparation method thereof

Abstract

The invention discloses a soil improving agent. The soil improving agent is prepared from the following raw materials in parts by weight: 10 to 20 parts of montmorillonite, 7 to 15 parts of oyster shell, 9 to 18 parts of earthworm excrement, 5 to 13 parts of sugar residues, 3 to 8 parts of chlorite, 13 to 25 parts of straw, 5 to 10 parts of marsh residues, 7 to 11 parts of turfy soil, 3 to 5 parts of lignin, 2 to 7 parts of polyacrylamide, 9 to 16 parts of rice bran, 3 to 7 parts of fish meal, 4 to 8 parts of silkworm excrement, 2 to 5 parts of humic acid, 1 to 2 parts of calcium carbonate, 2 to 3 parts of ammonium dihydrogen phosphate, 3 to 6 parts of potassium chloride, 1 to 2 parts of sterilizing agent, and 2 to 3 parts of activated carbon. The soil improving agent has the advantages that the acid soil can be neutralized, the growth of crops is promoted, the output is increased, and the diseases and pests can be prevented.

Description

technical field

[0001] The invention belongs to the technical field of agriculture, and in particular relates to a soil conditioner and a preparation method thereof. Background technique

[0002] Generally speaking, due to the uncontrolled spraying of various inorganic fertilizers and pesticides that are applied to the country's agricultural soil every year, the remaining components after the crops are absorbed are accumulated in the soil, which eventually leads to the loss of self-purification ability of the soil, and gives Crop growth poses great obstacles.

[0003] As a result, the soil is rapidly acidified, and the activity of microorganisms is reduced due to the gradual reduction of food for microorganisms in the soil, and the production of gas is inhibited due to the lack of organic matter that should be decomposed by microorganisms. Therefore, there is no breathing space for the soil. Reduce the fertility of the soil, which in turn will adversely affect the growth an...
