| titleOfInvention | Soil conditioner and preparation method thereof |
| abstract | The invention belongs to the field of soil improvement, and discloses a soil conditioner which mainly comprises chitosan oligosaccharide, rhamnose ester, calcium peroxide, trace mineral nutrients, auxin, animal wastes, 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. (1) The soil conditioner can improve the bulkiness and the void degree of the sticky soil, improve the soil structure forming capability, activate the soil and avoid soil hardening; (2) the soil conditioner can improve the micro-ecological environment of the rhizosphere soil of the crops, stimulate the root development of the crops and enhance the stress resistance and disease resistance of the crops; (3) the soil conditioner can chelate heavy metal ions in soil, activate the activity of nutrients in the soil and facilitate the absorption and utilization of crops; (4) the soil conditioner can obviously improve the crop yield, the corn yield can be increased by 9.6 percent at most, and the disease rate is less than 5 percent. |
