Straw carbonization returning soil improvement method

Abstract

The invention relates to the technical field of soil improvement methods, and discloses a straw carbonization returning soil improvement method. The method involves a straw carbonization device, whichmainly comprises a mounting shell, a combustion bin and a mixing bin; the combustion bin is arranged above the mixing bin; an ignition mechanism is mounted on the inner cavity wall of the combustionbin; a hole is formed in the inner wall of the combustion bin and is provided with a flue; and inner cavities of the combustion bin and the mixing bin are communicated with each other. According to the method, the effect of straws is maximized, the excellent effect of the straws on the soil is brought into full play, the physical, chemical and biological properties of the soil can be improved through the mixture of a soil conditioner in the carbonization process, the soil conditioner is more suitable for plant growth, and the method is one of effective methods for restoring the comprehensive production capacity of the soil. The preparation method disclosed by the invention integrates transportation, mixing and carbonization, is continuous in production and high in yield, and is suitable for large-scale production, and the mixing quality of the soil conditioner is stable.

Description

technical field [0001] The invention relates to the technical field of soil improvement methods, in particular to a soil improvement method for straw carbonization and returning to the field. Background technique [0002] Straw carbonization is a process in which the straw is dried or sun-dried and crushed, and then in the charcoal equipment, the loose straw is made into charcoal through drying, carbonization, cooling and other processes. The production of straw charcoal makes good use of the energy in the straw, but the traditional straw carbonization device has uneven feeding and insufficient combustion, and the size of the final straw charcoal is also different, and the carbonization efficiency is low, which is not conducive to the treatment of straw. The physical, chemical and biological properties of the soil are difficult to change or improve, and are not suitable for large-scale production. Contents of the invention [0003] The purpose of the present invention is ...
