Problems solved by technology

[0002] Measures such as fencing, supplementary seeding, and fertilization are currently widely used in grassland restoration projects. The grasslands enclosed by fencing will recover naturally due to the elimination of livestock pressure. The long-term development of grassland economy; and although fertilization has achieved certain results, there are still defects such as single fertilizer effect and weak ability to improve soil

Abstract

The invention discloses a soil remediation substrate and a preparation method thereof, and relates to the technical field of soil remediation; the soil remediation substrate comprises the following raw materials in parts by weight: 30-50 parts of straws, 20-30 parts of soy sauce residues, 10-15 parts of fly maggots and 2-4 parts of phosphate solubilizing bacteria liquid, wherein the straws are annual plant straws, and the soy sauce residues are residues after soy sauce brewing. The soil remediation substrate is rich in fertilizer efficiency, can comprehensively supplement soil nutrient content, further nourish ground cover plants and improve the total biomass of the ground surface, and has an obvious remediation effect on grassland soil and overground vegetation. The soil remediation substrate is easily available in raw materials, simple and convenient to prepare and suitable for large-area popularization and application.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a soil restoration matrix and a preparation method thereof. Background technique [0002] Measures such as fencing, supplementary seeding, and fertilization are currently widely used in grassland restoration projects. The grasslands enclosed by fencing will recover naturally due to the elimination of livestock pressure. The long-term development of the grassland economy; and although fertilization has achieved certain results, there are still defects such as single fertilizer effect and weak soil improvement. [0003] Therefore, how to provide a soil remediation matrix rich in fertilizer efficiency and environmental friendliness is a problem to be solved urgently in this area. Contents of the invention [0004] The invention discloses a soil restoration matrix and a preparation method thereof. The soil restoration matrix has rich fertilizer effect and lo...
