AI Technical Summary

Technical Problem

Existing technologies cannot provide stable and continuous cold protection for garlic seedlings during the emergence period, especially for the tender stem base after breaking through the soil, under the concept of green agriculture development, which makes seedlings susceptible to frost damage.

Method used

The system employs a combination of mulch film, seedling tube assembly, and phase change insulation component. The mulch film has through holes, and the seedling tube contains the phase change insulation component, which is a mixture of fatty acid phase change material encapsulated in microcapsules and diatomaceous earth. These components are connected by thermal fusion to form a closed microenvironment, and the phase change material regulates the temperature within the range of -2℃ to +2℃.

Benefits of technology

It achieves stable and continuous heat protection for the base of garlic seedling stems, significantly reduces the rate of frost damage, improves the uniformity of emergence and the yield in the later stage, and meets the requirements of green agriculture.
