Abstract

The invention relates to a carbon-based purple soil water retention agent and a preparation method of the water retention agent, and belongs to the technical field of soil improvement. According to the water retention agent and the preparation method, a bacterium stick waste void is deeply opened by microwave treatment; silica gel generated by hydrolysis of ethyl silicate is filled in the bacterium stick waste void by ultrasonic oscillation; the macro aggregate content and the stability of soil are increased and improved by compounding fulvic acid with the silica gel; and the problems of low organic matter content, poor structure and weak water storage and retention capacity of the soil are effectively improved by cooperating with good water storage and retention capacity of the silica gel. Bacterium stick waste is taken as a raw material; a resource is rich; the waste is recycled; and the water retention agent and the preparation method have wide application prospects.

Description

technical field [0001] The invention relates to a carbon-based purple soil water-retaining agent and a preparation method thereof, belonging to the technical field of soil improvement. Background technique [0002] Purple soil is a kind of mineral soil with shallow weathering development, low soil organic matter content, poor structure, and weak water storage and water retention capacity, and is widely distributed in the Sichuan Basin. The sloping farmland in the purple hilly area is the main part of local agricultural production. The precipitation in this area is relatively large and concentrated. Under the condition of heavy rain, the soil is easily eroded, and the water and soil loss is serious, resulting in shallow soil layer, reduced water storage and water retention capacity, and seasonal drought. and other problems worsen. Previous studies on soil and water conservation in sloping farmland mainly focused on the slope-to-terrace project, agroforestry planting, straw m...
