Carbon-based soil conditioner for sticky saline-alkali soil

Abstract

The invention discloses a carbon-based soil conditioner for sticky saline-alkali soil, and relates to the technical field of soil conditioners, and the carbon-based soil conditioner comprises the following raw materials in percentage by weight: 45%-60% of biomass charcoal, 5%-10% of pyroligneous liquor, 10%-15% of humic acid, 5%-10% of phosphogypsum, 10%-15% of furfural residue and 5%-10% of aluminum sulfate. By utilizing the porous structure characteristic of the biochar, the water and fertilizer retention capacity of the soil is improved; by adding the biomass charcoal particles, the soil carbon pool can be increased, soil pores can be increased, the soil viscous structure can be improved, and the soil microbial environment can be improved; the pyroligneous liquor effectively kills soilpathogenic bacteria and prevents and treats soil-borne diseases; the carbon-based soil conditioner is rich in soluble organic carbon and organic acids, and can stimulate crop growth, adjust soil pH, activate medium trace elements, improve soil and improve soil fertility level; the biochemical humic acid can improve the soil structure, improve and fertilize soil and stimulate crop growth; and the furfural residues can effectively reduce the pH of the soil. By adopting the carbon-based soil conditioner, seedling protection, high quality and high yield of crops in viscous saline-alkali soil are realized.

Description

Technical field: [0001] The invention relates to the technical field of soil conditioners, in particular to a carbon-based soil conditioner for heavy saline-alkali land. Background technique: [0002] Saline-alkali land is a general term for various saline soils and alkaline soils, as well as salinized and alkalized soils to varying degrees. The problem of soil salinization is currently one of the most serious environmental problems in the world. With the population growing and the arable land gradually decreasing, the improvement and utilization of saline-alkali land is very important for the sustainable and healthy development of agriculture and rural economy, land management, The protection of the ecological environment is of great significance. Ningxia has been prosperous since ancient times due to the irrigation of the Yellow River, and is known as "the south of the Yangtze River". However, some areas of the local Yellow River irrigation area are severely salinized, ha...

Problems solved by technology

Ningxia has been prosperous since ancient times due to the irrigation of the Yellow River, and is known as "the top of the south of the Yangtze River". However, some areas of the local Yellow River irrigation area are severely salinized, have high salt content, and have a large area of ​​medium-low yield fields, which seriously restricts agricultural development.

In recent years, Ningxia has continued to improve saline-alkali land through engineering, agronomic and other measures. At present, the treatment effect has appeared, but the treatment and utilization of local cracked alkaline soil and severe saline-alkali wasteland is still a problem
