Description

Technical Field

[0001] The present invention relates to the technical field of garden construction, and particularly to an ecological and efficient dust suppressant for garden construction and a preparation method thereof. Background Technique

[0002] The concept of garden engineering has broad and narrow meanings. Broadly speaking, it is a comprehensive landscape construction project, which is the whole process from the project start to design, construction and later maintenance. Narrowly understood, garden engineering refers to the process of making the target garden area into a specific beautiful landscape area through engineering means and artistic methods by on-site construction of each design element of the garden. That is, within a specific range, through artificial means (artistic or technical), multiple design elements (also called construction elements) of the garden are processed engineeringly so that the garden land meets certain aesthetic requirements and artistic atmosphere. This process of project implementation is garden engineering. During the construction process of the garden, a large amount of dust is easily generated, which will damage the surrounding environment and the health of construction workers. Existing dust suppressants cannot carry out dust suppression according to the on-site dust concentration, resulting in the failure of the dust suppressant to meet the suppression requirements, reducing the dust suppression effect and dust suppression time of the dust suppressant. Therefore, a special biochar slow-release tobacco planting fertilizer and its preparation method are needed during the tobacco planting process.

[0003] The inventor found that at least the following problems in the prior art have not been solved: 1. Existing dust suppressants cannot carry out dust suppression according to the on-site dust concentration, resulting in the failure of the dust suppressant to meet the suppression requirements, reducing the dust suppression effect and dust suppression time of the dust suppressant; 2. During the production process of the dust suppressant, long-term mixing and emulsification are required, resulting in poor production time of the dust suppressant and reducing the production efficiency of the dust suppressant; 3. After the production of the dust suppressant, the effect and production quality of the dust suppressant cannot be detected, thus reducing the success rate of the inhibitor production. For this reason, the present invention designs an ecological and efficient dust suppressant for garden construction and a preparation method thereof. Summary of the Invention

[0004] The purpose of the present invention is to provide an ecological and efficient dust suppressant for garden construction and a preparation method thereof, so as to solve the problems proposed in the above background technique that existing dust suppressants cannot carry out dust suppression according to the on-site dust concentration, resulting in the failure of the dust suppressant to meet the suppression requirements, reducing the dust suppression effect and dust suppression time of the dust suppressant, and it is not convenient during the production process of the dust suppressant, long-term mixing and emulsification are required, resulting in poor production time of the dust suppressant and reducing the production efficiency of the dust suppressant, and after the production of the dust suppressant, the effect and production quality of the dust suppressant cannot be detected, thus reducing the success rate of the inhibitor production.
