Hardened soil loosening agent and preparation method thereof

Abstract

The invention discloses a hardened soil loosening agent and a preparation method thereof, which particularly relate to the field of soil improvement. The hardened soil loosening agent comprises immature soil, plant powder, animal waste, potassium acetate, calcium superphosphate, calcium carbonate, charcoal, waste cement, waste paper and a microbial fermentation agent. The preparation method comprises the following steps of uniformly mixing plant powder with potassium acetate, adding raw soil, uniformly mixing to obtain a mixture 1, uniformly mixing the mixture 1 with animal manure, and adding a microbial fermentation agent for fermentation to obtain a fermentation mixture, adding calcium superphosphate and calcium carbonate into the fermentation mixture, and uniformly mixing to obtain a mixture 2, uniformly stirring and mixing the mixture 2 with charcoal and waste paper to obtain a mixture 3, grinding waste cement into ash, adding the ash into the mixture 3, and uniformly mixing to obtain the hardened soil loosening agent. The loosening agent can quickly improve the soil problem of hardened soil, does not need to depend on large-scale mechanical equipment, does not need to reduce the cultivation frequency, and does not damage the soil.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a compacted soil loosening agent and a preparation method thereof. Background technique [0002] Soil compaction refers to the phenomenon that the surface layer of the soil is poor in structure due to the lack of organic matter, and the structure is destroyed and the soil material is dispersed under the action of external factors such as irrigation or rainfall, and the soil surface is hardened by the cohesive force after drying. [0003] There are about 7 main factors of soil compaction. 1. The soil texture of the farmland is heavy and the clay content in the shallow clay of the cultivated layer is more. In addition, the average cultivated layer is less than 20cm, and the capillary pores in the soil are less, and the ventilation, water permeability and temperature increase are poor. After the rain. The soil aggregate structure is destroyed, resulting in a crust on the soil surfac...
