Abstract

The invention relates to the technical field of soil conditioners, and particularly relates to a garden waste biomass carbon based soil conditioner and a preparation method thereof. The garden waste biomass carbon based soil conditioner consists of the following raw materials in parts by weight: 50-100 parts of garden waste biomass carbon, 10-15 parts of fermented soybean residues, 10-15 parts ofplant ash, 1-5 parts of chitin, 10-15 parts of sodium bentonite, 5-10 parts of sodium lignin sulfonate and 1-5 parts of nano titanium dioxide. The garden waste biomass carbon based soil conditioner and the preparation method thereof provided by the invention have the beneficial effects that the garden waste biomass carbon is adopted as a basic raw material, the characteristics of the garden wastebiomass carbon as biomass carbon are fully utilized, and then the raw materials such as the fermented soybean residues, the plant ash, the chitin, the sodium bentonite, the sodium lignin sulfonate andnano titanium dioxide are selected to be matched with the garden waste biomass carbon, so that the gas permeability of soil can be effectively improved, the soil volume weight is reduced, contaminated soil is repaired, the soil microbial activity is promoted, and the soil fertility and the water permeability are enhanced.

Description

Technical field [0001] The invention relates to the technical field of soil conditioners, in particular to a garden waste biomass carbon-based soil conditioner and a preparation method thereof. Background technique [0002] In recent years, due to the large and unreasonable use of pesticides and the discharge of industrial wastes into farmland, soil problems have become more and more serious. Soil organic matter has been severely destroyed, soil nutrients have been lost, and the release rate has slowed. At the same time, soil aeration is caused by soil compaction. Decrease, the permeability coefficient decreases, and the activity of microorganisms in the soil decreases. These soil problems directly affect the quality and yield of crops. Therefore, the development of efficient and environmentally friendly soil conditioners has become an urgent problem in my country’s agricultural development. [0003] The minerals or rocks currently used as soil improvement regulators mainly include ...
