Abstract

The invention belongs to the field of soil improvement, and discloses a soil conditioner. The soil conditioner is mainly composed of chitosan oligosaccharide, rhamnolipid, calcium peroxide, trace mineral nutrients, auxin, animal waste, plant ash and volcanic ash, wherein the polymerization degree of the chitosan oligosaccharide is 5-15, and the molecular weight of the chitosan oligosaccharide is 500-2000 Da. The soil conditioner has the advantages that (1) the bulkiness and porosity of heavy soil can be improved, soil structure forming ability is improved, the soil is activated, and soil hardening is avoided; (2) the soil conditioner can improve the micro-ecological environment of rhizosphere soil of crops, stimulate the development of root systems of the crops and enhance the stress resistance and disease resistance of the crops; (3) the soil conditioner can chelate heavy metal ions in the soil, activates the activity of nutrients in the soil, and facilitates nutrient absorption and utilization of crops; and (4) the soil conditioner can obviously improve crop yield, wherein corn yield can be increased by 9.6% at most, and a disease rate is less than 5%.

Description

technical field [0001] The invention belongs to the field of soil improvement, in particular to a soil conditioner and a preparation method thereof. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants, and its thickness is generally about 2m. Soil not only provides mechanical support for plant growth, but also provides fertility elements such as water, fertilizer, air, and heat for plant growth and development. [0003] Due to the rapid population growth and rapid industrial development, solid wastes are continuously stacked and dumped on the soil surface, harmful wastewater is continuously infiltrated into the soil, and unreasonable use of herbicides, pesticides, chemical fertilizers, hormones, etc. have resulted in soil pollution. The polluted soil loses its normal function, the physical and chemical properties of the soil deteriorate, the soil is compacted, or the fertilizer nutrients in t...
