Soil improvement composition and soil improvement method

Abstract

The invention belongs to the technical field of soil improvement, and discloses a soil improvement composition and a soil improvement method. According to the soil improvement composition and the soil improvement method, the soil improvement composition is prepared from the following components in parts by mass: 300 to 700 parts of straw, 700 to 1300 parts of chicken manure, 15 to 40 parts of lime sulfur, 150 to 200 parts of calcium superphosphate, 250 to 500 parts of oil cake, 20 to 30 parts of activating agent, 30 to 40 parts of chloride ion supplement, 3 to 5 parts of stabilizing agent, 15 to 47 parts of filling agent, 5 to 10 parts of activated carbon powder and 5 to 10 parts of polyethylene powder. According to the soil improvement composition and the soil improvement method, the improvement composition adopts various biological raw materials, has no pollution to the environment, can help the soil to quickly return to fertility, is beneficial to back ploughing of cultivated land, and is low in raw material cost and easy to popularize on a large scale.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement composition and a soil improvement method. Background technique [0002] In order to grow products with good quality and high yield, a large amount of various organic and inorganic fertilizers and pesticides are usually sprayed, resulting in the accumulation of their remaining components in the soil, resulting in the loss of self-purification ability of the soil, and the long-term use of chemical fertilizers such as nitrogen and phosphorus Using it will destroy the soil structure, cause soil compaction, degrade the cultivated land soil, shallow the cultivated layer, reduce the ability to retain water and fertilizer, and bring great obstacles to crop growth. Therefore, the research on soil improvers has become a hot spot of concern. However, the types of modifiers commonly used are relatively single, and some modifiers will also pollute the environment,...

[0002] In order to grow products with good quality and high yield, a large amount of various organic and inorganic fertilizers and pesticides are usually sprayed, resulting in the accumulation of their remaining components in the soil, resulting in the loss of self-purification ability of the soil, and the long-term use of chemical fertilizers such as nitrogen and phosphorus Use will destroy the soil structure, cause soil compaction, degrade the cultivated land soil, shallow the cultivated layer, reduce the ability to retain water and fertilizer, and bring great obstacles to crop growth. Therefore, the research on soil improvers has become a hot spot of concern.

However, the types of modifiers commonly used are relatively single, and some modifiers will also pollute the environment, which is time-consuming and wastes resources.
