Problems solved by technology

[0003] At present, the main raw materials for the preparation of nutritious soil include garden soil, leaf humus soil, mountain mud, river sand, rice ash, plant ash, bone meal, sawdust, pine leaves, etc. Many commercially available nutritious soils have poor slow-release effects and are applied to plants. During cultivation, the surface soil is easy to harden when it is dry, and has poor ventilation and water permeability when it is wet.

Abstract

The invention discloses a method for preparing compound fertilizer-conserving nutritional soil from anaerobic fermentation residue. The compound fertilizer-conserving nutritional soil is mainly prepared from biogas slurry, biogas residue, garbage leachate, adsorbing material and surface oil as raw materials; the ratios of the materials are 5-15% of biogas slurry, 20-35% of biogas residue, 35-55% of adsorbent for absorbing leachate in a city refuse landfill, 20-40% of surface oil and 1-2% of inorganic fertilizer. The nutritional soil provided by the invention can promote the root part to breathe and absorb nutrients, so the plant can gain chronic and long-term nutritional ingredients; the process adopts fermentation residue and garbage leachate as primary materials; the cost is low, and the process is simple.

Description

technical field [0001] The invention relates to a method for preparing compound fertilizer-preserving nutrient soil with anaerobic fermentation residue, and belongs to the technical field of plant cultivation. Background technique [0002] Nutrient soil is a bed soil specially formulated to meet the growth and development of plants, containing a variety of mineral nutrients, loose and ventilated, strong in water and fertilizer retention, and free of diseases and insect pests. [0003] At present, the main raw materials for the preparation of nutritious soil include garden soil, leaf humus soil, mountain mud, river sand, rice ash, plant ash, bone meal, sawdust, pine leaves, etc. Many commercially available nutritious soils have poor slow-release effects and are applied to plants. During cultivation, the surface soil is easy to harden when it is dry, and has poor ventilation and water permeability when it is wet. Contents of the invention [0004] The object of the present ...
