To mitigate this damage you could:

wrap the stem of the young plant in aluminium builders insulating paper up to a height of around 40cm, or the first branch. The paper with a tar centre-layer is stronger and thicker and gives better protection than the cheaper paper.
erect 4 posts around each tree, and wrap the structure in cloth such as windbreak cloth.
cover the roof of the protective structure with quality frost cloth.
Spray around the base of each seedling to maintain bare earth. This helps absorb maximum solar energy during the day.
