Description

Technical Field

[0001] The utility model relates to the technical field of ecological management, in particular to a rhizome cutting device for ecological management using a fermentation method. Background Art

[0002] In large-scale ecological and environmental governance, the most common construction and renovation work is the elimination of invasive plants. Its construction and exploration methods often use chemical agents for elimination or manual physical removal. Both methods have certain disadvantages, whether it is the destruction of soil or the waste of human resources. The fermentation method of ecological governance uses enzyme bacteria to ferment the roots, and the crushing of the roots by the rotary tiller can effectively eliminate invasive plants and reduce the chance of recurrence. While the enzyme bacteria ferments and destroys the invasive plants, it converts them into high-quality organic fertilizers, turning invasive plants into treasures. The ecological governance method includes the following process steps: building a water retaining embankment, cutting and crushing the upper structure of the plant, applying enzyme bacteria, rotary tillage and crushing the lower structure of the plant, washing the planting bed, TTC method activity detection, fermentation and moisture control, etc.

[0003] When using a rotary tiller to crush the lower part of the plant, the blade rotates at a certain speed and moves forward in a random manner, cutting and crushing the roots. The mechanical crushing and rotary tillage depth reaches about 30 cm. Through the crushing and rotary tillage, the plants, enzyme bacteria and soil are fully integrated into a sludge state. However, most of the existing rotary tiller blades are an integral structure with three sets of blade teeth formed in one piece. When one set of blade teeth is damaged, the entire blade needs to be replaced, resulting in a waste of resources. Utility Model Content
