My peach tree bark is splitting open in huge areas and curling back. Also, the trees have not blossomed in the past two years.

Splitting most commonly occurs in freezing weather. If the wound is not weeping or splitting further, then you should just leave it alone to heal on its own. If the split is widening, you can try protective paper (sold at nurseries) to help hold it together while it heals. Do not cover the wound with tar or any other permanent substance as this can trap disease in the wound.
Splitting bark may occasionally be caused by borers as well. This article will help determine if this is the case for your peach tree: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-borer.htm
