Abstract

The invention discloses a clayed soil conditioner, a preparation method and a clayed soil improvement method, and belongs to the technical field of soil improvement. The clayed soil conditioner is prepared from the following parts in parts by weight: 500 to 1000 parts of solid additive material, 350 to 550 parts of organic biological fertilizer and 40 to 70 parts of compound microbial agent, the solid additive material comprises 80-120 parts of fine sand, 60-90 parts of zeolite, 20-40 parts of lignite powder, 10-20 parts of expanded graphite powder, 1-2 parts of triterpenoid saponin and 1-2 parts of sodium lignin sulfonate. Solid addition materials are adopted for physical improvement, the organic biological fertilizer and the compound microbial agent are adopted for biochemical improvement, multiple improvement methods jointly cooperate, the physical and chemical properties of clayed soil are improved by the clay improver comprehensively and effectively, soil hardened is avoided, and the content of organic matter in the soil is increased.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a sticky soil improver, a preparation method and a sticky soil improver. Background technique [0002] Clay soil is mainly distributed in the Yangtze River Basin in my country. Clay soil is also called clay soil, which refers to soil with less sand content, fine particles, slow water seepage, good water retention performance and poor ventilation performance. Clayy soil is the soil whose plasticity index is greater than 10 and whose particle size is greater than 0.075mm, and the content of particles with a particle size greater than 0.075mm does not exceed 50% of the total volume, including clayey sand, sandy low liquid limit clay, high liquid limit clay sand, sandy high liquid limit Clays and high liquid limit clays. This kind of soil generally refers to those with 45% physical clay particles, fine texture (sticky weight), including clay and heavy loam and some medium l...
