Abstract

The invention relates to the technical field of solid waste resource utilization and soil environment treatment. The invention relates to a saline-alkali soil improver carbon-based fertilizer and a preparation method and application thereof. The fertilizer is prepared by the preparation method comprising the following steps: introducing nitrogen into dried and crushed cotton straw particles, purging, sealing, putting the particles into a muffle furnace, carrying out temperature programming, carrying out a pyrolytic reaction, washing with water, drying, crushing, screening to obtain cotton straw carbon, mixing the cotton straw carbon and a chemical fertilizer according to a ratio, and granulating to obtain the saline-alkali soil improver carbon-based fertilizer. The physical and chemical properties of the saline-alkali soil can be effectively improved; the content of total available nitrogen, phosphorus and potassium in the soil is increased, the activity of enzymes in the soil can be improved, the stress resistance of plants is improved, the salt content of the saline-alkali soil is effectively reduced, the water retention rate of the soil is increased, meanwhile, resource utilization of agricultural waste can be achieved, and the saline-alkali soil improver carbon-based fertilizer has the advantages of being environmentally friendly, economical and efficient and can be widelyapplied to wheat cultivation soil improvement.

Description

technical field [0001] The invention relates to the technical fields of solid waste resource utilization and soil environment treatment, and relates to a saline-alkali soil improver carbon-based fertilizer and a preparation method and application thereof. Background technique [0002] There are large areas of saline-alkali land in my country that need to be improved and utilized, and there is an urgent need for improvement measures and technologies for saline-alkali land. Land salinization has become an important factor restricting the sustainable development of agriculture. With the continuous growth of population, the demand for food and other agricultural products is increasing, and the development and utilization of saline-alkali land is imminent. Rational use of saline-alkali soil can not only increase crop yield and alleviate food crisis, but also control environmental pollution and improve environmental ecological quality. On the one hand, Xinjiang has formed a large...
