AI Technical Summary

Technical Problem

Existing technologies cannot simultaneously meet the needs of seedlings for winter frost protection and root development. Traditional frost protection methods cannot raise soil temperature, leading to stagnation of root development and failure to replenish water in time, thus inhibiting seedling growth.

Method used

Design a seedling antifreeze device for forest cultivation, including a base, heat exchange mechanism, support mechanism and water supply component. Utilize mechanical linkage and natural monsoon power to increase soil temperature and supply water through frictional heat generation and air heating. Combined with plastic sheet support to regulate temperature, achieve adaptive regulation of soil temperature and moisture.

Benefits of technology

It effectively breaks the dormancy mechanism of seedling roots, promotes root development, ensures soil moisture, improves seedling growth efficiency, shortens the timber production cycle, and adapts to the forest cultivation needs of cold northern regions.

Abstract

The invention relates to the technical field of seedling cultivation, in particular to a seedling anti-freezing device for forest cultivation, which comprises a base and a water inlet, the base is hollow and has a water storage function, the outer wall of the base is made of a rubber and plastic material and has a heat preservation effect, and at least two heat exchange mechanisms are equidistantly mounted on the upper surface of the base along the circumferential direction. The heat exchange mechanisms extract moisture in the air and supplement water for the saplings, the supporting mechanisms are installed between the heat exchange mechanisms, the bottoms of the supporting mechanisms are fixed to the base, and the supporting mechanisms support the plastic cloth to prevent the saplings from being frozen. A sapling root dormancy mechanism caused by low temperature is effectively broken, sapling rhizomes are prevented from frostbite and death, and a proper temperature environment is provided for root development; soil moisture evaporation can be effectively avoided, the soil moisture content is continuously guaranteed, growth and development of sapling roots are promoted, and then the tree fruiting period is shortened; the temperature can be increased by increasing the light condensation performance to avoid low-temperature inhibition of sapling growth, and the temperature can also be reduced by reducing the light condensation performance to prevent high-temperature seedling burning.
