DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0022] The technical terms in the embodiments will be explained as follows: The heat preservation plate is a functional plate that reduces heat transfer and maintains the temperature stability of the target area through the low thermal conductivity of the material itself or special structural design, and is widely used in the fields of agriculture, construction, industry, etc. In the frost prevention and cultivation management of fruit trees, the heat preservation plate creates a suitable microclimate environment for plant root systems and tree trunks by blocking external low temperature and reducing heat loss. Its core role and technical principle are as follows: Low thermal conductivity materials: common materials include polystyrene (EPS), polyurethane (PU), rock wool, phenolic foam, etc. The thermal conductivity is usually lower than 0.03 W / (m·K), which is only 1 / 50 of that of concrete (1.7 W / (m·K)). Effect: can significantly reduce the heat conduction rate, for example, a 2cm thick EPS plate can make the inside temperature 8-10℃ higher than the outside in a-10℃ environment.

[0023] Reflective layer: surface coated with aluminum foil or reflective paint, reflecting thermal radiation (reflectivity can reach more than 90%), reducing radiation heat transfer.

[0024] Air barrier layer: built-in aluminum foil or plastic film, blocking water vapor permeation, preventing the increase of thermal conductivity due to condensation.

[0025] Support layer: use high-strength materials (such as glass fiber mesh) to enhance impact resistance and adapt to complex outdoor environments.

[0026] Trunk wrapping insulation: The insulation is molded into an arc-shaped plate, wrapped around the trunk to the first branch, which can prevent winter low temperature freeze-cracking bark, and avoid the "strip" phenomenon caused by spring cold.

[0027] Wind barrier: The vertically installed insulation board can weaken the wind speed by 30%-50%, reducing the exposure of root system and trunk shaking damage caused by wind erosion.

[0028] Blocking overwintering eggs: The insulation board covering the tree disc can destroy the survival environment of overwintering pests in the soil, reducing the pest density.

[0029] Reducing the spread of pathogens: By keeping the tree disc dry, inhibiting the spore germination of soil-borne diseases (such as root rot), and cooperating with pesticide treatment, the incidence can be reduced.
